1.What Is Applied Linguistics?

1).What is applied linguistics? Why is there no consensus on its definition and scope?

①Applied linguistics aimed to solve problems in various fields by applying the knowledge of linguistics.②As applied linguistics is a comparatively new discipline, there is as yet no consensus of opinions as to what its definition is and how wide its scope should be.

2.What is the role of applied linguistics? Why does it play that role?

① The role of applied linguistics

Linguistics, etc. ←→ Applied Linguistics ←→

Language Teaching, etc.

Figure---The role of applied linguistics as a mediator.

②Applied linguistics thus not only provides principles and basic methodology for language teachers, etc., based on the theories and insights of linguistics, sociolinguistics, psycholinguistics, etc.; it also provides feedback to linguistics, sociolinguistics, psycholinguistics, etc., by summing up the experience from the practical areas such as language teaching.

3.What is the nature of applied linguistics? What is the difference between applied linguistics and other applied sciences?

Answer: the nature of applied linguistics

(1) It is an independent discipline in its own right, because

* it has its own object of study;

* it has its own scientific system of theories and methodology; and

* it has its own researchers.

(2) It is an interdisciplinary science, because it draws upon theories not from a single science,

but from several. Besides, its application is also interdisciplinary in the broad sense.

(3) It is an applied science. Its goal is to solve problem, i. e. application, unlike pure science.

But we should not understand application in a narrow sense. Applied linguistics is also concerned with implications of the theoretical fields such as linguistics, sociolinguistics and psycholinguistics.

(4) It is an empirical science. Like natural sciences, it uses experiments as its basic way of research, emphasizing objectivity, systematicness, explicitness and economy.

The goal of applied linguistics is to solve problem, i.e., application. But we should not understand application in the literal sense. Applied linguistics is also concerned with implications of the theoretical fields such as linguistics, sociolinguistics, psycholinguistics.

4.What is the relationship between applied linguistics and language learning and teaching? Answer: Good language teaching practice is based on good theoretical understanding, and a good language teaching theory will strive to provide a conceptual framework devised for identifying all factors relevant in the teaching of language and relationship between them and for giving effective direction to the practice of language teaching, supported by the necessary research and inquiry.

5.Why is it necessary for the language teacher to learn applied linguistics?

Answer: Applied linguistics aims to provide language teachers with good language teaching

theories, principles and methodology. The language teacher can benefit from applied linguistics in, at least, the following three areas: a comprehensive and up-to-date grasp of the theoretical foundations of language learning and teaching; an integrated understanding of the various factors affecting language learning and teaching, and a basic knowledge about different language teaching approaches, methods and techniques. In short, applied linguistics will help the language teacher teach more effectively.

Chapter 2

Language, Learning and Teaching

1.What is the nature of language? Why is it necessary for the language teacher to know it?

Language is systematic and generative. It is a set of arbitrary symbols and they have conventionalized meanings to which they refer. is used for communication. operates in a speech community or culture. language and language learning both have universal characteristics.

By system: we mean the recurring patterns or arrangements or the particular ways or designs in which a language operates. Every language contains two systems: a system of sound and a system of meaning. This phenomenon is called duality.

―arbitrary vocal symbols‖: Anything that represents something else is a symbol.

Language consists of another type of symbols, sound symbols or speech sounds.

human communication: Language is a unique system of communication. It is the cement of society. It allows people to live, work and play together, to tell the truth or to tell lies.

Teachers cannot hope to teach a part (the particular language) of reality without knowing how that part fits into the whole(language in general) Your understanding of the components of language will determine to a large extent

how u teach a language.

2.What are the similarities and differences between human learning and animal learning?How do you understand language learning?

Animal learning for simple communication .express the food source, very simple emotion like anger and happiness. human learning complex idea. hypothesis , give command, thinking. Language learning in a broad sense include both formal learning in the classroom

stimulated by teaching and natural informal language learning without instruction from any teacher.

Learning is the prerequisite and basis of teaching.A theory of teaching always implies a theory of learning.

3.What is teaching? Can it be defined apart from learning? Why(not)?

①Teaching can be defined as ―activities which are intended to bring about learning. ‖

②Teaching cannot be defined apart from learning, because teaching presupposes learning. There will be no teaching if learning does not take place.

4.Illustrate the relationship between language teaching and language learning?

J. S. Bruner---1966 Toward a Theory of Instruction ―Learning something with

the aid of an instructor should, if instruction is effective, be less dangerous or risky or

painful than learning on one’s own.‖

Teaching understand the learners’ development ,skill, motivation and gives formal instruction ,training, by media or different kind of supportive activities. thus makes

learning easier.

5. Why is it necessary for the language teacher to have some knowledge not only of teaching but also of learning?

Since the mid-1960s,the student-centered view has been widely accepted, This reflects the theory that the students play an active role in learning ,and that they are not only actively participating in classroom activities ,but are interacting with the teacher and their peers.

Chapter 3

1. What are the characteristic features of human learning?

conceptualization of learning has several implications:

1). Everything we learn is retained in some form in our brain, even though it may be forgotten.

2.)Learning cannot be equated with behavior or performance.

3). Learning includes not only deliberately acquired new associations but also those acquired without conscious awareness, when we are paying primary attention to something else.

4). The new associations which constitute learning vary in meaningfulness and complexity. 5). All learning depends upon environmental input.

6). Learning is not restricted to new associations or insights that result from experience with purely external stimuli.

2、What are the four general philosophical views of human nature? How are they related to human learning?

The pessimistic view

According to this view, humans are inherently evil. Therefore, education must be designed to keep dangerous instincts under control. This philosophy leads to approaches which emphasize the will not engage in higher intellectual pursuit voluntarily, but they will learn if they are forced to.

The hedonistic view

According to this view, people are selfishly preoccupied with the pursuit of pleasure and the avoidance of pain. This philosophy leads to approaches which emphasize the need to make learning experience as enjoyable and intrinsically rewarding as possible.

The optimistic view

According to this view, people are naturally altruistic, humanistic and curious. This view leads to theories that picture people as thirsting for knowledge and actively processing information from the environment.

The tabula-rasa or ―blank-slate‖ view

This is a neutral view. According to this view, humans have few if any natural predispositions. Development, therefore, is dependent upon the individual’s experiences, which are determined by the environment and are thus open to planning and control. In its strongest form, this approach pictures learners as almost entirely passive and reactive, so that their behavior can be controlled predictably and systematically through environmental manipulation. Teaching then becomes a matter of structuring learning environments so as to produce desired outcomes.

3、What are the similarities and differences between classical behaviorism and neobehaviorism?

Similarities: They are predominantly concerned with the relationship between stimulus and response. According to them, behavior is acquired or changed when the organism builds up associations between stimulus and response either because of the closeness of stimulus and response or by satisfaction which comes from giving a correct response to a given stimulus.

Differences: classical behaviorism is related to association between stimuli and reflexive response, Classical conditioning, Reflex could also occur in response to stimuli that appear to be indirectly related to the reflex. neobehaviorism focuses on operant conditioning VS respondent conditioning (Classical conditioning). classical behaviorism stressed the environmental modifiability of behavior, as against determination by constitutional structure. Neobehaviorism : Guthrie stressed classical conditioning and the principle of contiguity over instrumental conditioning and the principle of reinforcement. Hull stressed one-trial learning. The whole process was controlled by reinforcement. Skinner stresses a particular kind of instrumental conditioning known as ―operant conditioning‖ . Operants are any behavioral ele ments or series f related behaviors that organisms presently perform or are capable of performing, and the produce an effect or operate on the environment.

4、What are the strengths and weaknesses of the behaviorist theories?

Watson’s behaviorism: he stres sed the environmental modifiability of behavior, as against determination by constitutional structure. He seek to make psychology a ―purely objective experimental branch of natural science‖ by restricting it to the study of the relations between environmental events(stimuli) and behavior(response). But there will be an increase in both frequency and recency of successful responses until a correct S-R pattern appears.

Guthrie’s S-R theory: He stressed classical conditioning and the principle of contiguity over instrumental conditioning and the principle of reinforcement. However, it has difficulty accounting for more complex kinds of learning.

Hull’s S-O-R theory: Hull stressed one-trial learning. The whole process was controlled by reinforcement. Reinforced responses would be more likely to appear in the future, and punished or unreinforced responses were less likely to reappear.

Skinner’s operant conditioning: he stresses a particular kind of instrumental conditioning known as ―operant conditioning‖ . Operan ts are any behavioral elements or series f related behaviors that organisms presently perform or are capable of performing, and the produce an effect or operate on the environment. Otherwise, when there is a punishment(i.e a positive reinforcing stimulus is removed or a negative reinforcing stimulus is presented), the rate of responding decreases.

5、What are the similarities and differences among the cognitive learning theories? Why are they cognitive?

Gestalt psychology: eh emphasizes on innate organizing principles(gestalt) in human perception, recognition, sensorimotor skills, learning and even in social conduct . according to this theory, organisms are innately active in their interactions with the environment.

Piaget’s developmental psychology: his basic concepts are assimilation and accommodation. He

refers to the learning process as the development of new schemata (the plural of schema) through assimilation and accommodation. Schemata are the cognitive or mental structures by which the individual intellectually adapts to and organizes the environment. These cognitive structures are used to process and identify incoming stimuli.

Ausubel’s theory of meaningful learning: according to ausubel, meaning is a ―clearly articulated and precisely differentiated conscious experience that emerges when potentially meaningful signs, symbols, concepts or propositions are related to and incorporated within a given individual’s cognitive structure on a non-articulatory and substantivebasis‖ human learning is a meaningful process of relating new events or items to already existing cognitive concepts or propositions. Meaning is therefore a process of relating and anchoring new material to relevant established entities in the learner’s cognitive structure. Meaningful learning takes place when the learner has a disposition to relate the new material to what he already knows or when the learning task is potentially meaningful

If we can conceive of cognitive structure as a system of building blocks, then rote learning is the process of acquiring isolated blocks with no particular function in the building of a structure, and therefore with no relationship to other blocks. Meaningful learning is the process whereby blocks become an integral part of already established categories or systematic clusters of blocks.

6、What do you think of the different learning theories? What is your own view of human learning?

Cognitive theories place greater store by the functioning of the mind, and postulate internal mental thinking as well as processes including perception, memorizing and cognitive structures which can be acquired from learn ers’ experience and can modify their present behavior. Much greater emphasis is placed on learners being aware of the surroundings and being flexible in solutions they adopt.

1. Is it easy for the child to acquire his mother tongue? Why (not)?

No, it is not easy for the child to acquire his mother tongue.

First of all, he must segment the sound stream into meaningful units (words or phrases). This requires his ability to analyze. Then, he must combine them to arrive at the intended underlying propositions. This requires his ability to synthesize.

2. What questions must theories of L1 acquisition answer? Why?

Psycholinguists who study child language are confronted with a more complex task than theoretical linguists whose major concern is competence (i.e. the system of language) and sociolinguists whose major concern is performance (i.e. the use of language). Psycholinguists have to be concerned with both competence and performance.

Because they look at language from different angles, and because their purposes in the study of language are different.

3. Sketch out Skinner’s behavioristic theory of L1 acquisition.

Skinner’s behavioristic model is embodied in his classic Verbal Behavior. His theory of verbal behavior is in fact an extension of his general theory of learning by operant conditioning. According to Skinner, verbal behavior, like other human behavior, is controlled by its consequences. When consequences are rewarding the behavior is reinforced and maintained, and

even increased in strength and frequency. When consequences are punishing or when there is no reinforcement, the behavior is weakened and eventually extinguished. Therefore, effective language is the production of correct responses to external stimuli. The L1 acquisition process is one in which the child’s correct responses are repeatedly reinforced and finally a habit is formed.

4. What are the main points of mediation theories? Why are they called mediation theories?

Mediation theories are represented by O. H. Mowrer and C. E. Osgood. Their goal is to fill the ―black box‖ with postulated internal psychological structures and processes in order to account for the observed behavior of organisms. They have developed a principle of mediated association, according to which two things associated with a third thing tend to be in association with each other. Once the association is established, an internal link is built up even when the third thing is not present.

They need media. The internal mediating response is considered to be an internal replication of a ―real‖ response. From a behavioristic point of view, meaning is an internal replica of an external response.

5. How do the nativist theories account for L1 acquisition?

Nativist theories are represented by N. Chomsky, E. H. Lenneberg, and D. McNeill. According to these theories, human babies are somehow predisposed to acquire a language. Lenneberg contends that language is a species-specific behavior which is biologically determined. The child is born with the biological basis for the acquisition of language. Chomsky claims the existence of a little black box which he calls the language acquisition device (LAD). He regards it as ―the genetically determined language faculty”, ―an innate component of the human mind that yields a particular language through interaction with presented experience.‖ McNeill describes four innate linguistic properties of the LAD and suggests that infants are born with a hierarchy of linguistic categories and the basic grammatical relations.

6. What are the main arguments of the cognitive theories?

Cognitive theories are represented by D. I. Slobin, J. Piaget and L. Bloom, who attempt to account for the linguistic knowledge of the child by a more general theory of cognitive development. Slobin suggests that the conceptual development of all human children is the same with regard to the order of attainment of conceptual categories and that a number of cognitive prerequisites lie behind the emergence of communicative speech. Slobin characterizes this development as new functions first expressed in old forms. Piaget outlines four major stages of intellectual development in the child, and claims that intelligence actually develops well before language. Stage One, the sensory-motor stage(ages 0-2). Stage Two, the preoperational stage(ages 2-7). In the first stage(ages 2 to 4 or 5) the child’s language is egocentric speech. In the second stage(by ages 6-7), the child’s language has become socialized speech, which is characterized by intercommunication and exchange of ideas. Stage Three, the concrete operational stage (ages 7-11). Stage Four, the formal operational stage(ages 11-16). Bloom concludes that the development of perception and cognition are keys to the understanding of the process of child language acquisition.

7. What do you think of the different L1 acquisition theories?

There is one common problem with all of the theories. They all ignore the social aspect of L1 acquisition. Just as Armstrong et al point out‖…language acquisition studies show that language does not develop through an individual’s interaction with the natural environment. It emerges only

out of social interaction, but social interaction within constrained limits…Without the introduction to words and seminal idea that words symbolize—without the initial acquisition process which is social—we would have no equipment with which to make linguistic inferences.‖

1.Illustrate the use of the terms second language and foreign language

In the past, the term ―foreign language‖ was most widely used in contrast to ―native language‖. But in recent decades, the term ―second language‖ has been increasingly used to refer to all types of non-native language. In certain cases, they are distinguished from each other. According to Stern , ―second language‖ is used to refer to a non-native language learned and used within one country or community where it has official status or a recognized function, whereas ―foreign language‖is used to refer to a non-native language learned and used outside the country or community where it has official status or a recognized function. In a second language context, the target language is spoken by the community outside the classroom, whereas in a foreign language context, the target language is generally not spoken by the community but is limited to the classroom.

2.What does it mean to know a second language?

Knowing a language means having acquired the competence ore proficiency in the language. The idea goal of competence or proficiency in a second language is the native speaker’s competence or proficiency in the language, which is necessary point of reference for the concept of second language proficiency.

3.What is meant by second language proficiency ? How can the learner attain it?

Knowing a language means having acquired the competence or proficiency in the language. The ideal goal of competence or proficiency in a second language is the native speaker’s competence or proficiency in the language, which is a necessary point of reference for the concept of second language proficiency. Stern conceptualizes this native speakers’ proficiency as follows: 1. The intuitive mastery of the forms of the language, 2. The intuitive mastery of the linguistic , cognitive , affective and sociocultural meanings expressed by the language forms, 3. The capacity to use the language with maximum attention to communication and minimum attention to form, and 4. The creativity of language use.

4.Who is a better second language learner, the child or the adult? Why ?

Adults and old children in general initially acquire the second language faster than young children(older id better for the early stage of acquisition), but child second language acquires will usually be superior in terms of ultimate attainment(younger is better in the long run). We can explain it from three main aspects: the biological explanation, the cognitive explanation, and the affective explanation.

5.What does interlanguage refer to? What is the nature of interlanguage? Do you think we can apply this concept to foreign language learning? Why (not)?

The term interlanguage was defined differently by different experts, but now we say that inter language is in fact a language system bordering on the first language and the target language. I don’t think we can apply it to foreign language learning, because it has only a minor impact on L2 pedagogy.

6.How do you understand Kranshen’s monitor theory? Do you think it is applicable to

foreign language learning ? Why (not)?

Krashen’s monitor theory is considered the best known most ambitious most influential of all L2 theories. It has brought together research findings from a number of different domains, is closely tied to recommendations for classrooms practice and is readily understandable to L2 teachers. So I think it can be applied to foreign language learning.

7.How do Burt and Dulay account for the internal processing of second language ? Is foreign language learning also a creative construction process? Why (not)?

The creative construction model is developed by Burt and Dulay in 1977 to account for the internal processing of second language. It is based on Chomsky’s linguistic theory of creative aspects of language use. Foreign language learning is also a creative construction process. Creative construction in language acquisition refers to the process by which learners gradually reconstruct the rules for speech they hear, guided by innate mechanisms which cause them to formulate certain types of hypotheses about the language system being acquired, until the mismatch between what they are exposed to and they produce is resolved.

Chapter 6

1. How are different types of learning related to learning English as a foreign language? Learning has been classified in many different ways .The most useful classification is based on the task of learning (i.e. what is being learned).Based on the nature of the learning task, three types of learning are identified :skill learning ,affective and social learning, and cognitive learning .

Type 1,signal learning

This is a somewhat specialized type of learning.It is called signal learning to emphasize that the learner is associating an already available response with a new signal or stimulus .One important characteristics of this type of learning is that it involves the Pavlovian conditioned response ,which is general ,diffuse ,and emotional.This kind of response has a truly ―involuntary‖character .A fear response ,for example,involves general ,diffuse activity including speeded heartbeat,constriction of blood vessels and other internal involuntary behavior .In our daily life, learning to respond to alarm clock bells or automobile horns falls into this type of learning .

Type 2,stimulus-response learning

Type 3 chaining

Type 4 verbal association (or sequence)

Type 5 multiple discrimination

Type 6 concept learning

Type 7 principle learning

Type 8 problem-solving

Language learning is a complex task which involves all these types of learning . For example,in learning the pronunciation of a second language,the learner is concerned with how to produce the appropriate sound patterns –a sensorimotor skill or part of a skill.If the learner cannot distinguish two sounds and therefore cannot pronounce them,he needs to know the articulatory description of the two sounds .This involves conceptual learning.The actual learning of a second language is accompanied by emotional reactions, and entire learning experience may lead to a fixed constellation of likes and dislikes directed towards the language and the people speaking that

language.

2.Illustrate the general learning strategies with examples from yourself or your Students in learning English.

ways in which a learner attempts to work out the meanings and uses of words, grammatical rules, and other aspects of a language

metacognitive strategies :1.thinking about the mental processes used in the learning process2.monitoring learning while it is taking place, 3.evaluating learning after it has occurred A. advance organizersB. directed attentionC. selective attentionD. self-management

E. functional planning

F. self-monitoring

G. delayed production

H. self-evaluation

cognitive strategies:processes and behavior which learners use to help them improve their ability to learn or remember something, particularly those which learners use with specific classroom tasks and activities

A. repetition

B. Resourcing

C. translation

D. grouping

socioaffective strategies:social-mediating activity and transacting with others

3.What are the major strategies employed by good students in your class?

Tarone defines learning strategy as attempts to develop linguistic and sociolinguistic competence in the target language. The motivation for the use of learning strategy is the desire to learn the target language rather than the desire to communicate .Production strategies are used to accomplish communication goals;they reflect an interest in using the language system efficiently and clearly without excessive https://www.sodocs.net/doc/4812901674.html,munication strategies are an adaptation to the failure to realize a language production goal.They therefore serve an important role in negotiating meaning between individuals.

Rubin suggests that the good language learner :

1)is a willing and accurate guesser

2) has a strong drive to communicate

3)is often uninhibited about his weaknesses in the L2 and ready to risk making mistakes

4)is willing to attend to form

5)practices

6)monitors

7)attends to meaning in its social context

Stern identifies four basic sets of strategies from the basic considerations and research of language learning:

1)Active planning strategy Good language learners will select goals and subgoals,recoginize stages and developmental sequences and actively participate in the learning process

2)‖Academic ―(explicit)learning strategy Good language learners are prepared to study and practice .They pay attention to the features of language as a formal system with rules and regular retationships between forms and meaning.

3)Social learning strategy Good language learners seek communicative contact with target language users and are active participants in authentic language use

4)Affective language Good language learners can cope effective with the emotion and motivational problems of language learning .They approach the task of L2 learning in a positive frame of mind and cultivate positive attitudes towards themselves as language learner s, towards

language and language learning in general,and towards the target language and its society and culture.

4.What is the difference between learning strategy and learning style?

There was significant difference between learning strategy and learning style.,but it simply existed in one type of learning strategy.

Three learning styles (visual,auditory and kinesthetic)did not influence all the six types of learning strategies (memory, cognitive, compensation, metacognitive, affective and social).The learning styles only influenced the use of social strategies.

In addition ,after the Post Hoc Scheffe test,researchers found that learners with auditory learning styles use more social strategies than those with vusual learning style.

In conclusion, the common element in all these styles involves the way people perceive problems and the effect this might have on the paths taken to a resolution.In this sense, learning styles are more general and abstract than learning strategies,for learning style refers to the way people perceive problems , whereas learning strategies refer to the paths they take to arrive at a solution of the problem.

5.Discuss the relevance of the three pairs of learning styles to learning English as a foreign language.

Field independence vs.field dependence

A field-independent person tends to perceive analytically . That is ,he tends to perceive particular relevant items in a field as discrete from the field as a whole. A field-dependent person, on the other hand, tends to perceive globally; his perception tends to be dominated by the total field.As a result,the parts embedded in the field are not easily perceived. It has been found that field-dependent persons tends to show a strong social orientation; they are usually more empathetic and more perceptive of feelings of others. Field-independent persons , on the other hand, tend to show an ―impersonal orientation‖; they are generally individualistic and less aware of the things by which others are moved.Some researchers have found that the field-independent person is the better L2 learner because he will be better able to focus on the relevant variables in a language lesson or a conversation.Other researches, however, have found that field-dependent persons are superior L2 learners because of their social orientation. Brown speculates that field-independence may be more important in traditional classroom settings with a strong emphasis on analysis on analytical activities, whereas field dependence may be more important in the natural setting. In language learning it is often necessary to understand language items in their context and at the same time it is also necessary to classify the items out of that context to understand them paradigmatically . Therefore , the optimal degree of both may be necessary for successful language learning.

Reflectivity vs.impulsivity

The person who makes an impulsive, off-hand response is an impulsive, whereas the one who is prepared to pause and reflect on the mature of a question and the accuracy of the answer is a reflective . Reflectives tend to be more anxious about the quality of their performance and more capable of sustained attention than impulsives. It has been found that impulsive learners make more errors in L2 reading than reflective learners but they are faster readers. However , Hewett has found that subjects who rate themselves more frflective athan impulsive achieve significantly

better reading scores.Kagan et al. have found that inductive reasoning seems to be more effective with reflective learners.

Broad vs.narrow category width

It has been found that L2 learners who are broad categorizers tend to overgeneralize rules they have learned because they tend to subsume too many items under one rule,whereas narrow categorizers have difficulty in making generalizations, which are necessary for efficient L2 learning,because they tend to create a rule for every item. Naiman et al. have hypothesized that the best language lcarners would be those who neither generalize too much nor too little. That is to say, both operations are needed under different circumstances in language leaning;the good language learner is probably a ―middle-of-the-roader‖,reasonably precise in the application of rules and yet prepared to take risks in order to test the limits of a rule.

6. Why is it necessary for the language teacher to have some knowledge of these cognitive variables?

Three major groups of cognitive variables: types of learning, strategies of learning and styles of learning. The first is related to learning tasks, whereas the other two are related to individual characteristics of learners.

It is noteworthy that the combination of those variables constitutes a multiplicity of individual differences in language learners. The teacher needs to recognize and understand those differences so as to provide optimal opportunities for his learners.

To have some knowledge of these cognitive variables will undoubtedly help the language teacher to get a better understanding of students’ learning potential and eventually contribute to language teaching.

财政学知识点整理完整版

*财政学知识点整理 第一章 1、古代欧洲最早的财政思想的表现者是古希腊的色诺芬。在《雅典的收入》一书中,他讨论了希腊雅典的财政收入问题,并建议由国家购买奴隶,并将他们出租以增加国家的收入。 2、春秋战国的《国语- 齐语》中管仲提出了“ 相地而衰征,则民不移”的财政政策 3、威廉·配弟的《赋税论》被誉为西方最早的财政学专著。此书是在重商主义向古典经济学派的过渡阶段。 4、第一个从理论上系统阐述财政理论的经济学家是英国古典经济学的代表人物亚当·斯密三.现代财政理论 5、凯恩斯以前的经济理论,并不认为经济会一直处于充分就业的状态,但认为偏离充分就业的状态是暂时的。 6、凯恩斯主义者以《就业、利息和货币通论》为理论基础,把经济危机的根源归结为 “ 有效需求不足”,要求政府放弃自由资本主义原则,实行国家直接干预经济生活,提出了政府运用财政货币政策,增加投资,刺激消费,实现充分就业的一整套理论政策体系。 第二章财政学的福利经济学基础 1、意大利经济学家和社会学家帕累托建立了公共决策的理论基础。 2、帕累托效应及其实现条件【资源配置最优】:任何政策的改变都不可能在不使任何人的境况变坏的情况下使某个人的境况变好。这一概念常常被作为评价资源配置合意性的标准。 实现条件:竞争可以保证帕累托效率条件的实现 3、边际替代率:边际替代率是指在产量保持不变的前提条件下,增加一单位某种生产要素可以代替的另外一种要素的数量。通常,由于生产过程中投入的生产要素是不完全替代的, 随着一种生产要素数量的增加,该要素对另外一种要素的边际替代率是递减的。

4、无差异曲线及其特征:无差异曲线( Indifference curve )是一条表示线上所有各点两种物品不同数量组合给消费者带来的满足程度相同的线 特征:第一,无差异曲线是一条向右下方倾斜的线,斜率是负的;第二,在每种商品都不被限定为多了比少了好的前提下,无差异曲线图中位置越高或距离原点越远的无差异曲线所代表的消费者的满足程度越高;第三,任何两条无差异曲线不能相交;第四,无差异曲线通常是凸向原点的,这就是说,无差异曲线的斜率的绝对值是递减的 5、追求结果的公平——功利主义、罗尔斯主义、平等主义: 【1】功利主义:边沁早在1789 年便提出社会行为的目的应该是“增进最大数人的最大幸福”。这种被称为功利主义的思想追求的是个人效用总和的最大化。个人所得税制度 的累进设计符合功利主义的公平观。 ( 功利主义者认为①个人的效用可以用技术来衡 量,社会福利是所有社会成员福利的总和。②如果财富从富人手里转移到穷人手中造成穷人效用的增加大于富人效用的减少,被认为收入分配比以前公平。 ) 【2】罗尔斯主义 (短板效应) :社会福利仅仅取决于境况最差的个人的福利情况,即只有境况最差的人的状况得到了改善,社会福利才会得到改进。 第三章市场失效与财政职能 1、信息完备:p42 信息不对称:当交易双方中一方掌握的信息多于另一方时就存在信息不对称。 ① 逆向选择:市场交易中的一方无法观察到另一方的重要的外生特征时所发生的劣质品驱逐优 质品的情形。 ② 道德风险:市场交易的一方无法观察到另一方控制和采取的行动时所发生的知情方故意不采 取谨慎行为的情形,由于知情方故意不采取谨慎行为也许会招致对交易中另一方的损害。 2、囚徒困境:p44 反映了一个很深刻的问题,就是个人理性与集体理性的矛盾。 3、外部效应:p44 一个人或企业的行动影响了其他人或企业的利益,但又没有负担应有的责任或没有获得应有的报酬,公式:U A=U A(X1,X 2, ?X n,Y 1) 某一个人或企业的效用所控制的活动其他人或单位的活动

中级微观经济学-考试试题

《中级微观经济学》 一、概念题(每题5分,共20分) 1、市场均衡 市场均衡意味着市场出清,即所有消费者在愿意支付的市场价格上都买到了所需商品,而生产者也在该价格水平上卖出了其愿意出售的全部商品。 2、边际分析法 一种经济分析方法。边际分析法指把追加的支出和追加的收入相比较,二者相等时为临界点,也就是投入的资金所得到的利益与输出损失相等时的点。 3、稀缺 稀缺性指物品现有的数量不能满足对它的需求。分为相对稀缺和绝对稀缺,经济学中研究的是相对稀缺。 4、机会成本 是衡量我们作出一项决策时所放弃的东西。一项决策的机会成本是作出某一决策而不作出另一项决策时所放弃的东西。还指厂商把相同的生产要素投入到其他行业当中去可以获得的最高收益。 5、规模经济: 指通过扩大生产规模而引起经济效益增加的现象。规模经济反映的是生产要素的集中程度同经济效益之间的关系。 6、自然垄断(又称自然独占) 指整个市场需求只要有一个企业就能得到满足,而不需要两个或更多的企业参与生产的垄断。自然垄断

由于规模经济而存在,垄断厂商的成本低于由多个厂商生产的成本。 7、边际效用: 边际效用指在一定时间内消费者增加一个单位商品或服务所带来的新增效用,即总效用的增量。也就是说,在其他条件不变的情况下,随着消费者对某种物品消费量的增加,他从该物品连续增加的每一消费单位中所得到的满足程度称为边际效用。 8、边际成本: 指每一单位新增生产的产品(或者购买的产品)带来的总成本的增量。 9、边际收益 指增加一单位产品的销售所增加的收益,即最后一单位产品的售出所取得的收益。它可以是正值或负值。 10、消费者均衡 指在既定收人和各种商品价格的限制下选购一定数量的各种商品以达到最满意的程度。消费者均衡是消费者行为理论的核心。 11、生产可能性曲线 指在技术知识和可投入品数量既定的条件下,一个经济体所能得到的最大产量。 12、需求价格弹性 指需求量相对价格变化做出的反应程度,即某商品价格下降或上升百分之一时所引起的对该商品需求量增加或减少的百分比。

财政学考试复习知识点汇总

税收中性:指政府课税不扭曲市场机制的正常运行,或不影响私人部门原有的资源配置状况。两种含义: ?国家征税使社会所付出的代价以税款为限; ?应避免对市场经济正常运行的干扰。 ?特别注意,税收的中性原则,并不意味着取消或忽视税收对经济的调节作用,而应在市场起基础性作用的前提下,有效地发挥税收的调节作用,使税收机制与市场机制两者取得最优的结合。 ?税收中性强调税收对经济不发生额外的影响,经济体系仅仅承受税收负担,不再给纳税人和社会造成其他额外损失或额外收益。其实质是,国家征税不应对市场机制产生影响,课税时,市场机制仍然是影响资源配置和纳税人决策的主要力量,税收不应成为影响资源配置和纳税人经济决策的主要因素 超额负担:政府通过征税将社会资源从纳税人转移向政府部门的过程中,给纳税人造成了相当于纳税税款以外的负担。 税收超额负担表现两个方面: –1、国家征税一方面减少纳税人支出,同时增加政府部门支出,若因征税而导致纳税人的经济利益损失大于因征税而增加的社会经济效益,则发生在资 源配置方面的超额负担。 –2、由于征税改变了商品的相对价格,对纳税人的消费和生产行为产生不良影响,则发生经济运行方面的超额负担。 马歇尔-哈伯格超额负担理论: 税收超额负担是由哈伯格运用马歇尔的基数效用理论作为基础理论提出的,使用了消费者剩余和生产者剩余概念,并以消费者剩余的大小作为衡量消费者在消费某种商品是获得净福利的多少,如图示: 税收中性和超额负担。 答:税收效率涉及税收中性问题。所谓税收中性是指政府课税不扭曲市场机制的正常运行,或者说,不影响私人部门原有的资源配置状况;如果政府课税改变了消费者以获取最大效用为目的的消费行为,或改变了生产者以获取最大利润为目的的市场行为,就会改变私人部门原来(税前)的资源配置状况,这种改变就被视为税收的非中性。税收中性包含两种含义:一是国家征税使社会所付出的代价以税款为限,尽可能不给纳税人或社会带来其他的额外损失或负担;二是国家征税应避免对市场经济正常运行的干扰,特别是不能使税收超越市场机制而成为资源配置的决定因素。只要国家征税就必然会对商品购买、劳动投入以及储蓄和投资等诸多方面产生不同程度的影响,在现实生活中保持完全税收中性是不可能的。因此,提出税收中性原则的实践意义,在于尽量减少税收对市场经济正常运行的干扰,使市场机制在资源配置中发挥基础性作用。在这个前提下,掌握好税收超额负担的量和度,有效地发挥税收的调节作用,使税收机制与市场机制两者取得最优的结合。 应当指出,体现税收的中性原则,并不意味着取消或忽视税收对经济的调节作用。一般是将增值税视为一种中性税收,我国1994年税制改革也体现了税收中性原则。 税收中性和税收超额负担相关,或者说,税收中性就是针对税收超额负担而提出的。税收超额负担是指政府通过征税将社会资源从纳税人转向政府部门的转移过程中,给纳税人造成了相当于纳税税款以外的负担。超额负担主要表现为两个方面:一是国家征税一方面减少了纳税人支出,同时增加了政府部门支出,若因征税而导致纳税人的经济利益损失大于因征税而增加的社会经济效益,则发生资源配置方面的超额负担;二是由于征税改变了商品的相对价,对纳税人的消费和生产行为产生不良影响,则发生经济运行方面的超额负担。税收理

一.简答题 1.机会成本相关 答:是指为了得到某种东西而所要放弃另一些东西的最大价值。 在稀缺性的世界中选择一种东西意味着放弃其他东西。一项选择的机会成本,也就是所放弃的物品或劳务的价值。机会成本是指在资源有限条件下,当把一定资源用于某种产品生产时所放弃的用于其他可能得到的最大收益。 2.劣等品和低档品的逻辑推导(P78) 答:低档品或劣等品(inferior goods):指消费量随收入的上升而下降的物品。 对于正常商品,替代效应与价格呈反方向变动,收入效应也与价格成反方向变动,所以总效应与价格成反方向变动,因此正常商品的需求曲线向右下方倾斜。对于低档品来说,替代效应与价格成反方向变动,收入效应与价格同向变动,但替代效应大于收入效应的作用,总效应与价格反方向变动,需求曲线向右下方倾斜。吉芬商品,替代效应与价格反方向变动,收入效应与价格通向变动,收入效应极大地大于替代效应,使总效应与价格同向变动,其需求线向右上方倾斜。 二.计算题 1.生产理论:已知企业的生产函数要素价格需求函数企业生产量 求:市场长期均衡的产品价格和企业数量 EG A: 已知生产函数为Q=KL-0.5L2—0.32K2,其中Q表示产量,K表示资本,L表示劳动,若 K=10,求: (1)写出劳动的平均产量函数和边际产量函数。 (2)分别计算出当总产量、平均产量和边际产量达到极大值时,厂商雇佣的劳动量。

(3)证明当APL 达到最大值时,APL=MPL=2 AN A: (1)TP=Q=10L-0.5L^2-30 把K=10带进去 边际产量(MPL )函数 就是上式对L 求导。MPL=10-L 平均产量(APL )函数 就是总产量除以投入的劳动。APL=TP/L=10-0.5L-30/L (2)当TP 最大时,MPL=0。令MPL=10-L=0 ,解得L=10,所以当劳动投入量L=10时,劳动的总产量TP 达到极大值。 当APL 最大时,是APL 与MPL 相交的时候。令APL 的导数=0,解得L=2倍根号15(负值舍去),所以当劳动投入量L=2倍根号15 时,劳动的平均产量达到极大值。 当MPL 最大时,是TP 以递减的速度增加。由MPL=10-L 可知,边际产量曲线是一条斜率为负的直线。考虑到劳动投入量总是非负的,所以劳动投入量L=0时,劳动的边际产量达到极大值。 (3)当劳动的平均产量APL 达到极大值时,一定有APL=MPL 。由(2)可知,当L=2倍根号15 时,劳动的平均产量APL 达到极大值, 即相应的极大值为 APLmax=10-0.5 * 2倍根号15-30/2倍根号15 =10-2倍根号15 又因为APL 达到极大值,有APL=MPL 所以 边际产量函数MPL=10-2倍根号15 很显然,当APL 一定有极大值时,APL=MPL=10-2倍根号15 EN B: 5.某完全竞争行业中每个厂商的长期成本函数为 。假设市场需求函数是。试求市场的均衡价格,数量和厂商数目. 解:已知LTC q q q =-+3248,则LAC q q =-+248,欲求LAC 的最小值,只要令d d LAC q =0,即 q -=240,q=2。 当每个厂商的产量为q=2时,长期平均成本最低,其长期平均成本为:224284LAC =-?+=。当价格p 等于长期平均成本4时,厂商既不进入,也不退出,即整个行业处于均衡状态。故行业长期供给函数即供给曲线是水平的,行业的长期供给函数为p=4。 需求曲线为d Q p =-2000100,而行业的供给函数为p=4。 所以行业需求量d Q =-?=200010041600 。 由于每个厂商长期均衡产量为2,若有n 个厂商,则供给量QS=2n 。行业均衡时,Qd=QS ,即 1600=2n ,n=800。故整业行个均衡价格为4,均衡产量为1600,厂商有800家。 EN C . 某竞争 行业所有厂商的规模都相等,都是在产量达到500单位时达到长期平均成本的最低点4元,当用最优的企业规模生产600单位产量时,每一个企业的短期平均成本为4.5元,市场需求函数为 ,供给函数为Q =40000+2500P ,求解下列问题: (1)市场均衡价格是多少?该行业处于短期均衡还是长期均衡? (2)当处于长期均衡时,该行业有多少厂商?

名词解释 财政政策是指国家根据一定时期政治、经济、社会发展的任务而规定的财政工作的指导原则,通过财政支出与税收政策来调节总需求。增加政府支出,可以刺激总需求,从而增加国民收入,反之则压抑总需求,减少国民收入。税收对国民收入是一种收缩性力量,因此,增加政府税收,可以抑制总需求从而减少国民收入,反之,则刺激总需求增加国民收入。财政政策是国家整个经济政策的组成部分。 财政补贴是指国家财政为了实现特定的政治经济和社会目标,向企业或个人提供的一种补偿。主要是在一定时期内对生产或经营某些销售价格低于成本的企业或因提高商品销售价格而给予企业和消费者的经济补偿。 财政投融资是指政府为实现一定的产业政策和财政政策目标,通过国家信用方式把各种闲散资金,特别是民间的闲散资金集中起来,统一由财政部门掌握管理,根据经济和社会发展计划,在不以盈利为直接目的的前提下,采用直接或间接贷款方式,支持企业或事业单位发展生产和事业的一种资金活动。

外部效应:指在实际经济活动中,生产者或者消费者的活动对其他生产者或消费者带来的非市场性影响。这种影响可能是有益的,也可能是有害的,有益的影响被称为外部效益,外部经济性,或正外部性;有害的影响被称为外部成本外部不经济性,或负的外部性。外部效应也可解释某个个经济主体的活动所产生的影响不表现在他自身的成本和收益上,而是会给其他的经济主体带来好处或者坏处。 起征点,又称“征税起点”或“起税点”,是指税法规定对征税对象开始征税的起点数额。征税对象的数额达到起征点的就全部数额征税,未达到起征点的不征税。 免税额是指对税法规定的课税对象全部数额中免予征税的数额。 税收支出:以特殊的法律条款规定的、给予特定类型的活动或纳税人以各种税收优惠待遇而形成的收入损失或放弃的收入。这是一种间接性支出,慎于财政补贴性支出。 平衡预算乘数:平衡预算指政府增加开支的同时,相应增加同量的税收。即政府税收增加量等于政府购买增加量时叫预算平衡。平衡预算乘数指政

财政学重点知识总结

财政 学 简述社会公共需要的基本特征。社会公共需要涵盖的范围颇广,包括政府执行其职能以及执行某些社会职能的需要。特征:(l)社会公共需要是社会公众在生产、生活和工作中的共同的需要,它不是普通意义上的人人有份的个人需要或个别需要的数学加总。(2)为了满足社会公共需要而提供的公共物品,可以无差别地由应当享受的每一社会成员共同享用,并不排斥其他社会成员享用。(3)社会成员享用满足社会需要的公共物品,无须付出任何代价,或只支付与提供这些公共物品的所费不对称的少量费用。(4)在市场机制不能解决外部效应产生的结果时,需要由政府通过财政渠道来解决,因而为满足社会公共需要提供的公共物品一般带有外部效应的特征。 (5)满足社会公共需要的物质手段只能来自社会产品的剩余部分,如果剩余产品表现为价值形态,就只 能是对“M”部分的抽取。 简述政府干预市场的主要手 段。在市场机制失灵的情况下,政 府可以采取以下三种手段干预市 场运行:(1)行政法律手段,即制 定市场法规,制定发展战略和中长 期规划,制定经济政策,引导和调 节经济运行。(2)组织公共生产, 即由政府出资(即由预算拨款)兴 办的所有权归政府的工商企业和 单位。(3)财政手段,即以税收、 收费、国债等形式筹集收入,又通 过转移性支出、购买性支出以及财 政政策等手段调节经济的运行。 试论社会主义市场经济条件 下的财政职能 下的财政职能。 。(l)资源配置职能。 ①确定社会公共需要的基本范围, 确定财政收支占GDP的合理比例, 从而符合高效的资源配置原则。② 优化财政支出结构,合理确定生产 性支出与非生产性支出的比例,购 买性支出与转移性支出的比例。③ 合理安排政府投资的规模、结构, 保证国家的重点建设。④通过政府 投资、税收和补贴,调节社会投资 方向,提高社会投资的整体效率。 ⑤提高财政配置本身的效率。 (2)收入分配职能。①划清市 场分配与财政分配的界限和范围, 原则上属于市场分配的范围财政 不能越俎代庖,凡属于财政分配的 范围,财政应尽其职。②规范由国 家预算拨款的公务员的工资制度 以及相类似的事业单位职工的工 资制度。③加强税收调节,通过间 接税调节各类商品的相对价格,从 而调节各经济主体的要素分配;通 过企业所得税调节公司的利润水 平;通过个人所得税调节个人的劳 动收入和非劳动收入,使之维持在 一个合理的差距范围内;通过资源 税调节由于资源条件和地理条件 而形成的级差收入;通过遗产税、 赠予税调节个人财产分布。④通过 转移性支出,如社会保障支出、救 济支出、补贴等,使每个社会成员 得以维持起码的生活水平和福利 水平。 (3)经济稳定与发展职能。① 财政政策,紧松交替。②通过一种 制度性安排,发挥某种“自动”稳 定作用,③通过投资、补贴和税收 等多方面安排,加快农业、能源、

1.为什么市场会存在缺陷和失灵? 1)市场缺陷:现实中市场充分竞争所需要的四个基本假设条件都是不充分的,或难以具 备,因而,在实际的资源配置过程中,市场本身出现低效率状态. 2)市场失灵:由于每个人只追求自我利益,那些满足社会公共需要的产品和服务却无人 提供,由此必然使社会处于难以运转的状态. 2.为什么要有政府?政府存在的合理性依据是什么? 由于市场失灵的存在,必须矫正其固有的缺陷和弥补市场失灵,这就需要某种不同于自利主体的公共主体执行这一社会职能.这种公共主体就是国家及其政府. 3.为什么把市场失灵作为一种方法?主要运用在哪些方面? 1)通过市场实验或试错来验证市场机制失灵的领域,由此确定政府和公共部门进入领 域的合理范围. 2)通过市场失灵方法,证明某些具有经营性质的事业单位可以推向市场,政府应从该” 越位”领域退出,而某些服务则不能简单推向市场,否则,其公益性就会丧失.例如,医 疗体制改革. 4.财政模式与财政体制有怎样的关系? 财政模式是财政体制的上位概念,财政模式是抽象存在的,而我们在认识某一国家的财政时,所看到的是具体的财政体制,可以根据财政体制的本质特征和属性指出其属于哪种财 政模式. 5.你怎样理解公共财政模式及其特征? 公共财政模式是与市场经济社会相对应的财政模式.该模式要求从市场与政府关系界定财政职能. 公共财政模式的基本特征: 1)公共财政是纳税人的财政 2)公共财政以弥补市场失灵,提供公共产品和公共服务为基本职能 3)公共财政应向社会提供一视同仁的服务 4)公共财政是民主财政 5)公共财政是法制财政 6.什么是财政伦理?应怎样认识公共财政的伦理价值标准? 1)财政伦理即关于财政在整个社会关系体系中进行活动应遵循的一系列价值标准或 道德标准. 2)公共财政的伦理从总原则上说,就是在市场经济中,全体纳税人将全部税收委托给政 府以用来弥补市场失灵,换言之,凡是用于弥补市场失灵的财政支出活动都是符合公 共财政的伦理的. 1.简析制约财政职能的因素 1)财政本质对财政职能的制约 职能是事物固有的功能,这种功能系事物本身的质所决定的.从这一角度看,财政本 质是决定财政职能最重要的因素.

财政学考试复习知识点汇总2

结合财政支出增长的若干理论分析财政支出增长的原因分析 1、对于支出不断膨胀的趋势,许多学者做了大量的研究工 作,其中尤以19世纪德国经济学家阿道夫·瓦格纳(Adolf Wagner)最为著名,他的研究成果被称为“瓦格纳法 则”(Wagner’s Law)。 导致政府支出增长的因素分为两方面: 政治因素:随工业化发展,经济中人们的交往增多,关系更复杂,需要政府把更多的资源用于提供治安和法律方面。 经济因素:工业化带动城市化,人口居住密集化,由此产生拥挤等外部性问题,要求政府进行调节。 瓦格纳把对于教育、娱乐、文化、保健与福利服务的公共支出的增长归因于公共物品需求的收入弹性大。 2、皮科克与瓦埃斯曼的替代—规模效应分析 3、马斯格雷夫和罗斯托的经济发展阶段分析规模。 影响财政支出规模的因素 一、影响财政支出规模的宏观因素分析 1.经济性因素 主要指经济发展水平、经济体制以及中长期发展战略 和当前经济政策等。 2.政治性因素 政局是否稳定、政体结构和行政效率、政府干预政 策。 3.社会性因素 人口、就业、医疗卫生、社会救济、社会保障以及城 镇化等因素。 物价上涨。 政府职能增加,政府机构扩大。 公共工程和国防费用。 2、 分析影响财政支出规模的微观因素: 福利经济学对财政支出增长的分析主要是从微观角度进行 的,它采用效用最大化的分析方法,将市场有效供给原理运 用到政府公共物品的供应中,通过影响财政支出增长的变 量。 如公共物品的需求、成本和价格、质量、生产组织形式等,来分析和研究财政支出 根据个人的理解,阐述改革开放以来财政支出的变化特征。 根据瓦格纳法则等对财政支出规模的一般性描述,财政支出规模
