第十三章 财政、货币政策的内容及其作用1 名词解释 （1）IS曲线:是指表示使得产品市场处于均衡利息率与均衡国民收入的不同组合描述出来的曲线。在IS曲线上,每一点表示的利息与国民收入的组合恰好使得投资等于储蓄。IS曲线向右下方倾斜。 （2）LM曲线:是指表示使得货币市场处于均衡的利息率与均衡国民收入的不同组合描述出来的曲线。在LM曲线上,每一点表示的利息与国民收入的组合恰好使得货币需求等于货币烘给。LM曲线向右上方倾斜。 （3）财政政策;政府为了实现宏观经济政策目标而对政府支出、税收和借债水平作出的选择,或对财政收人和财政支出所做出的决策。 （4）拉弗曲线;是描述税率与税收收入之间关系的。在一定范围内提高税率能增加税收;但如果税率超过一定比例,提高税率反而会使税收收入减少。 （5）货币政策:中央银行通过控制货币供应量,从而影响利率,影响投资并最终影响国民收入的宏观经济政策。 相似文献

一般均衡论：IS－LMFE模型分析,对于国际收支政策一货币政策和财政政策的效应评价,有着重要意义和积极作用。因此,仅就这一问题,谈谈个人粗浅的看法。一、一般的均衡论：IS－LM－FE模型简介（一）基本内容一般均衡论：IS－IAllerry模型的基本内容,包括：1、该模式建立的一个重要前提,是：总供给具有完全的弹性。因而,国内经济的均衡,即：IS－LM曲线的交点,总成立。2‘假定汇率不变,以固定汇率的条件。如果取这一决定,则会有FE的曲线的移动。因此,即使浮动汇率条件下,该模式仍然成立。3、国际收支差额为贸易差额与资本… 相似文献

文章以IS—LM模型为例,探讨了GAMS仿真在宏观经济学教学中的应用。具体的政策模拟可分为四个方面：（1）财政和货币政策分别对均衡国民收入、利率、消费和投资的影响;（2）财政和货币政策混合的综合影响;（3）IS和LM曲线斜率对财政和货币政策效果的影响;（4）实现经济目标的政策选择。GAMS仿真的结果不仅进一步验证了IS—LM模型的基本结论,同时也更为直观地体现了政策变动对经济的各种影响,研究结果对实验经济学在中国的应用与推广具有一定的参考价值。 相似文献

我国大部分中学地理教师应该在地理领域里引入G IS,但是他们对G IS并不了解。现在中学教育中有G IS内容,但还不够完善。由于硬件或软件等G IS环境的不完备,教师对G IS知识了解不够全面。地理课时间不足与地理课程教学大纲相关。G IS教育不兴的原因有:第一,按照国家教育共同基本科目、一般选修科目、深化选修科目等要求,对G IS学习目标划分不清;第二,没有按照各共同基本科目、一般选修科目、深化选修科目的学习内容水平分等级;第三,因为在独立的单元里同时运用G IS概念和应用,所以G IS教育的灵活运用受到了限制。 相似文献

Fast changing information technology (IT) has posed tremendous challenges to information systems (IS) educational programmes. One question frequently asked by IS educators has been: ‘Are we doing the right thing?’ This article presents information about the current state of IS educational programmes in the USA based on a survey of 193 higher education institutions conducted at the end of 1996. The results indicate that IS educational programmes are prevalent in the higher educational institutions. These programmes have a highly qualified faculty: 92% or more holding terminal degrees, more than two-thirds having tenure, with evidence of an increasing amount of time being devoted to research activities. It is also found that the most popular programming languages taught in both graduate and undergraduate programmes are C/C++, SQL and COBOL, and dominant operating systems are Windows/OS2 and UNIX. The most profound change over the last five years in the content of IS programmes has been the transition from text-based and centralized mainframe environment to the graphical and decentralized network based client–server architecture. This survey provides a snapshot of IS programmes, serving both to improve our understanding of current programmes and to provide a frame of reference for future studies. 相似文献

跨文化敏觉力被认为是成功进行跨文化交际的首要条件,而进行跨文化敏觉力培养的首要步骤便是跨文化敏觉力的调查与评估。该论文基于陈国明和Starosta关于跨文化敏觉力的理论,应用其设计的跨文化敏觉力量表,从大学文、理、工科学生中分别抽取样本来评估非英语专业大学生的跨文化敏觉力。对评估结果进行分析的基础上,作者发现了非英语专业本科学生在跨文化敏觉力的五个维度上的具体表现,并针对大学英语教学中如何提升学生的跨文化敏觉力提出了一些建议。 相似文献

The evaluation and selection of software tools for use in an IS or IT curriculum is difficult not only because actual industry software tools are often used but also because there is no formal approach to guide the process. How does one choose between SQL Server and MySQL, or Dreamweaver and Expression Studio? IS and IT educators must periodically go through the process of assessing the most suitable tools for their courses. Given how common such decisions are and how frequently they must be made, it is surprising to find that there is a lack of literature that deals with comparative studies of software tools for higher education. This paper proposes a set of criteria for the selection of software tools for IS and IT programs, explains how multi-criteria decision analysis can be used to weight those criteria, and details an approach for the application of those weighted criteria. The proposed approach is structured and replicable, and allows for a more thorough evaluation of the available options and a more easily supportable selection. 相似文献

当前。对女性作家的小说改编后的电视剧往往消解原著中的性别意识，回归到既定的性别形象和性别关系图式。由于创作者不同的社会性别观念和意识，在文本叙事中会体现出不同的性别视角。本文以《橘子红了》为例，通过对小说和剧本两个文本进行细读。从聚焦选择、人物描写、人物关系三个方面进行文本的叙事学分析，揭示文本中隐藏的性别视角，分析不同性别视角下文本的性别内涵。 相似文献

This paper describes an evaluation of the transition stages of “development assistance program” (DAP) international students (IS) at a large Australian research university. This group has different backgrounds that suggest distinct transition issues compared with students from wealthier families and/or more industrialized nations. We argue that a more circumspect “stakeholder” approach may be useful when investigating such programmes. Stakeholder theory offers a broader platform upon which to identify and realize mutual long-term interests. Using survey-based student self-reports, we analyse longitudinal quantitative data to examine developmental changes and interrelationships between various adjustment pathways. The results inform strategies for both staff and students to manage these transitions, especially by increasing students’ sense of control and predictability. The findings may assist other academics and administrators to enhance a range of IS programmes, and shed some light on some specific challenges and successes of DAP students. 相似文献

This paper backgrounds and illustrates an approach to researching didactic knowledge. Underlying the approach are some of the frameworks developed from the student learning research. Based on these frameworks the experience of learning about a particular phenomenon is theorised as having educationally critical aspects. Without addressing these aspects in learning experiences, students are highly unlikely to achieve the target understanding desired by the teacher. The approach developed to research educationally critical aspects compares scholarly and student experiences of learning about a phenomenon using the analytical framework of a structure of awareness. An application of the approach is reported in the form of a phenomenographic study which researched didactic knowledge about the concept of an information system (IS). Multiple, previously unreported, educationally critical aspects of learning about the concept of an IS were identified. Some implications of this finding for the design of IS undergraduate curricula, textbooks, teaching strategies and learning tasks are proposed. Finally, the research approach is promoted as a means to investigate didactic knowledge about other phenomena. 相似文献

Although group project concepts and skills have become a major component in most information systems (IS) academic programs, very little research has attempted to examine factors that may improve or undermine effectiveness of IS group projects. Accordingly, based on relevant literatures, this study develops and empirically tests a model of factors affecting IS group project effectiveness. The research model posits that group cohesion and group efficacy will have positive effects on group effectiveness (project success and expected impact), whereas perceived loafing is expected to have a negative effect on IS group effectiveness. Data collected from 104 students working in 29 groups to complete semester‐long projects in two IS courses revealed that group efficacy had positive impact on group effectiveness and perceived loafing demonstrated a partial effect. Contrary to expectations, the impact of group cohesion was nonsignificant. These results could be useful in evaluating groups' potential for success and creating conditions conducive to enhancing effectiveness and success of IS student group projects. 相似文献
