人民币实际汇率波动对我国贸易收支的影响——基于非对称协整的实证分析

基于1994年1月至2009年4月的数据,采用较新的非对称协整技术,实证考察人民币实际汇率与我国贸易收支之间的变动关系。研究发现,长期中,马歇尔-勒纳条件在我国成立;短期内,J曲线效应在我国存在;人民币汇率与贸易收支间存在非对称协整关系。其中,相对于出现过大的贸易顺差,如果出现贸易赤字,贸易收支恢复长期均衡状态的调整过程较为缓慢。据此认为,相对于出现贸易顺差,当前更应关注外贸不利冲击对我国经济所造成的负面影响。     

汇率变动对我国贸易收支影响研究——基于向量自回归模型分析

汇率变动的贸易收支结构效应是指汇率变动对出口和进口不同影响引起贸易收支的变化过程。考察汇率变动贸易收支结构效应,可以探讨汇率变动对收支平衡的作用,进而探讨汇率调节贸易收支的马歇尔一勒纳条件是否成立。本文采用向量自回归模型,以年度数据为基础探讨汇率变动的贸易收支结构效应,刻画两者之间的脉冲响应关系,从而得出我国实际汇率变动对我国出口贸易和进口贸易的影响,并提出相应政策建议。     

人民币实际有效汇率和对外贸易收支的关系——基于中国与东盟5国贸易的实证研究

东盟已经超过日本成为中国第三大贸易伙伴,在中国对外贸易中占有重要地位。利用协整方法,使用季度数据对中国—东盟5国的贸易收支和人民币实际有效汇率、东盟5国实际GDP、中国实际GDP之间的关系进行实证研究,发现这四者之间存在长期均衡的关系;人民币实际有效汇率和中国—东盟5国贸易收支之间存在因果关系;人民币实际有效汇率升值对中国—东盟5国贸易存在"反J曲线效应",即短期内人民币升值会改善贸易收支。因此,中国和东盟5国的双边贸易收支状况可以通过变动人民币实际有效汇率来调整。     

人民币实际汇率波动对中美贸易收支的影响——基于1990—2009年时间序列分析

基于协整理论、误差修正模型和格兰杰因果检验并根据中国和美国1990-2009年的季度数据,分析人民币实际汇率变动对中美贸易收支的影响.结果表明:影响中美贸易收支的主要因素包括美国的实际GDP、中国的实际GDP和人民币实际汇率,且三者的影响力次第减弱,中美贸易也存在明显的J曲线效应.因此,改善中美贸易失衡应扩大中国内需、调整业口结构和改革人民币汇率制度.

论人民币升值对我国贸易收支的影响

人民币汇率波动对我国与东盟六国贸易收支的影响研究

人民币汇率波动对我国国际贸易收支有着非常重要的影响。本文在数理统计和实证角度研究自2005年7月21日汇改以来人民币实际有效汇率波动对我国与东盟贸易收支的影响,主要选取东盟中六国(即印度尼西亚、马来西亚、新加坡、越南、泰国和菲律宾)为代表进行分析,运用面板资料模型得出结论:人民币实际有效汇率升高(即人民币升值),会缩小我国贸易收支顺差,人民币实际有效汇率波动对中国与东盟六国的贸易收支产生国别效应。对中国而言,在努力扩大出口促进经济增长的同时应该兼顾国家发展战略,可采取的措施有完善汇率政策、对贸易政策的调整和对产业政策的调整等。     

基于VAR模型的中欧贸易“J曲线效应”实证分析

欧元作为一种新兴世界货币既在全球经济中发挥日益重要的作用,也是人民币汇率形成机制中的重要权重货币,由于欧盟是中国最大的贸易伙伴,故欧元兑人民币实际汇率变动对中欧贸易平衡产生重要影响。本文采用1999—2008年间欧元兑人民币汇率数据和中国与欧元区贸易季度数据构建VAR模型,并运用单位根检验、协整检验和脉冲响应函数的分析方法对欧元汇率变动对中欧贸易相对差额的影响进行实证分析。结果表明,人民币兑欧元的贬值初期会引起中国对欧元区贸易收支的短期恶化,但经过一段时间后由于我国对欧元区出口数量增加,贸易盈余趋于稳定,中国对欧元区贸易存在汇率贬值的"J曲线效应"。     

人民币汇率波动对我国国际贸易的传导效应

本文考察了我国与11个主要国际贸易伙伴的进出口贸易情况,使用GARCH模型测算人民币汇率波动,应用ARDL协整方法研究在现行汇率制度下人民币汇率波动对我国国际贸易的传导效应,得出如下结论:一是总体上,人民币汇率波动对我国国际贸易具有负面的传导效应,国际贸易尤其是出口贸易会受到人民币汇率波动的影响;二是贸易伙伴经济发展对我国国际贸易有促进作用;三是我国国际贸易不易受到进出口产品相对价格变动的冲击.     

论人民币汇制改革对我国进出口贸易的影响--兼析人民币汇率的未来走势

本文对新汇制十个月的表现、人民币汇率的未来走势、汇改的贸易效应、中国高贸易顺差的根源等进行了研究.认为:我国贸易收支与汇率变动的相关度不高,中国的高贸易顺差是国际产业转移形成的"迁移效应"等深层次根源的结果,人民币升值的贸易收支改善效应不大,但对贸易条件和产业结构具有一定的改善作用;不管是从短期还是中长期来看,人民币仍会有较强的升值预期,要注重人民币升值的节奏,适取小幅度、慢性化、长期性升值的原则.

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.     

中国养活自己能力的长期预测:技术和政策分析

中国拥有世界五分之一强的人口 ,收入又在迅速增长。因此 ,国际上很自然地会考虑或推测她在今后的几十年是否有能力养活自己。中国的人口预计将从 2 0 0 0年的 1 2 8亿增长到 2 0 2 0年的 1 4 6亿 ,和 2 0 3 0年的 1 4 9亿。与此同时 ,人均收入的增长将导致对家畜和鱼类产品更大的需求 ,因而对饲料的需求也将有很大的增长     

John Stuart Mill's Theories of Wealth and Income Distribution

Although he was much influenced by David Ricardo when he wrote the classical part of his Principles , John Stuart Mill was not a Ricardian when he penned his theories of wealth and distribution. They are based on a triple foundation. First, a belief that economics is a moral discipline. Second a theory of custom-driven human behavior. Third, an empirically formed conviction that the institutions of state, education and business cooperate to structure the distribution of income. On the basis of these presuppositions, Mill formulated 1) an institutional theory of the formation of human and non-human wealth and 2) an even more institutional theory of distribution demonstrating how the aforementioned institutions malignantly skew the distribution of income to the advantage of the propertied classes and to the extreme disadvantage of the working class. As a social economist, Mill recommended institutional reforms designed to eradicate the poverty of the working class.     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.

Information infrastructure: Who builds broadband networks?

This paper examines the essential difference between the U.S. and Japan, when one considers information infrastructure. There are seven perception gaps between the U.S. and Japan concerning Information Infrastructure policies. These gaps must be understood in order to compare the countries' governmental policies in this area. In looking at the present circumstances, the essential question to answer concerns who is to build, own and operate the network(s) of the infrastructure. Liberalization is certain to be a central factor in the ongoing telecommunications debates. Now that customers have had a taste of the liberalized market-place, the movement toward more open markets will be difficult to stop. When considering options, it is necessary to pay close attention to standardized network access and the increasingly important role software plays. These issues are causing us to take a new approach to the traditional role played by regulators. They also force a closer look at the appropriate structure of utility companies. This paper addresses the above issues in hopes of stimulating dialog on the new telecommunications infrastructure paradigm.     

海岛地区产业演替及资源基础分析--以舟山群岛为例

改革开放以来,舟山市产业构成发生了显著变化,其经济发展过程可以划分为三个阶段。1992年前,是以产业结构渔业占绝对地位的单一结构阶段;1993—1998年,以旅游业为主的第三产业快速发展阶段;上世纪末以来,又进入了新一轮的经济发展时期,即工业产值比重快速增加阶段。根据海岛的自然资源基础和特点,在新世纪的经济发展过程中,舟山市应定位为生态型的港口旅游城市。以港口及临港工业为主导,以海岛旅游和海洋经济为特色,大力发展第二产业和第三产业。海岛地区的主导产业应体现海岛资源优势及区位优势,以集群性环保型产业为主。同时由于海岛地区淡水资源缺乏,主导产业也应着重选择低耗水型产业。
