CEPA框架下“大珠三角”区域经济格局演变的动力模式研究

世界性的区域经济一体化的动力模式一般都是从市场要素动力模式向制度动力模式演变.CEPA的实施,为"大珠三角"区域经济格局的调整提供了制度机遇,为此,文章提出以区域合作制度为导向,以区域创新为核心,从制度、产业、技术和空间等方面构建新的动力模式框架,以促进"大珠三角"动力模式从分散的市场要素动力模式转向制度动力模式.     

人民币国际化与国际货币体系改革

从美国债务上限调整的议案及美国信贷主权评级的下调,可见现行由美元和欧元所组成的二元国际货币体系并不稳定。为测度出人民币的引入能否增加国际货币体系的稳定性,本文先建立面板回归模型分析影响一国货币国际化的基础条件因素,并在模型的基础上,测度出人民币在可自由兑换后将成为一个能与欧元相互抗衡的国际货币。通过方差比较,本文论证了由美元、欧元和人民币三种货币所组成的外汇储备组合较二元体系下的稳定,说明人民币国际化有助于改革现行的二元体系,使国际货币体系发展成为更稳定的三元体系,从而促进全球经济的健康发展。     

旅游地阻力面理论初探--五大连池风景名胜区为例

以生态学中的阻力面理论为依托，创建了符合旅游规划需要的旅游地阻力面理论模型，构建了旅游景点、景区、旅游地、旅游区域之间联系的阻力层次体系，建立了旅游空间联系关系的影响因子系统，提出了旅游地阻力面理论在指导区域、地方及旅游区规划中的作用，并以国家级风景名胜区五大连池为例展示了旅游地阻力面理论在地方旅游开发建设实践中的现实作用。     

试论我国农地发展权定位及农民分享实现

经营性征地给社会经济发展带来许多不稳定因素,其中一个极为重要的原因是由于长期以来强大的行政权力取代了土地发展权的权效。从这一角度出发,文章首先介绍了发展权的含义和特征并总结了我国农地发展权的现状,在此基础上针对农地市地化过程中的土地发展权进行了定位,提出将发展权分享引入征地补偿机制即农民参与发展权权益的分享,紧接着探讨了发展权分享实现问题,并对农民发展权分享进行了量化。旨在通过对发展权的适当安排缓解现行征地体制中的一些矛盾,从而在深层次上促进我国土地产权制度的健全和土地的合理利用。     

THE ACCOUNTS AND THE COMPUTER

(1) The primary contribution from the computer's application to the national accounts may well be to erode the line between micro and macro analysis. Key macro totals in the accounts sum individual company reports. The computer permits us to develop distributions of these reports. Such distributions, regularly presented, would permit discovery of the first forerunners of change, would help distinguish, e.g., widespread strength in an export drive or a profits surge, from participation by a few major concerns that dominate the aggregate.
(2) The strikingly different parameters in cross section and time series studies (e.g., price elasticity of housing) will in some measure reflect incomparability between the micro data that enter into each. The computer makes possible the use of the wide array of micro data that really underly the accounts to develop consistent analyses of time series (of both aggregates and distributions) and cross section analyses.
(3) The inconsistencies now imbedded in the accounts but gilded over by the abilities of the estimators are well-known. Discussions of wage price policy rest on data for wages that have no necessary compatibility with data on profits, etc. But since 1,500 corporations account for at least half of U.S. net income, sales, and investment, the computer can test the consistency of reports made by different units in these firms to different agencies—a process totally out of the question before the computer.
(4) The potential that the computer offers for prompt revisions in the accounts; for revisions by systematic rule; for tests of sensitivity of the entire set of accounts to particular tailor-made adjustments, is clear.
(5) Company purchase orders and accounts are increasingly recorded on cards or tapes. From these we may derive input-output detail and process detail that are light years better than those now feasible from intermittent survey aggregates.     

THE ROLE OF THE GOLD STANDARD IN THE GIBSON PARADOX

Recent papers by Lee and Petruzzi (1986) and Barsky and Summers (1988) provide rival theories of how the Gibson Paradox could result from the impact of changes in the interest rate on the real price of gold. This paper empirically tests each model and finds more support for the Lee-Petruzzi approach than the Barsky-Summers approach. The paper also suggests that Lee and Petruzzi may have used an inappropriate method to test their model, and that both papers employed inappropriate sample periods.     

土地征用中存在的主要问题

伴随着城市建设和经济发展,土地市场开发和土地征用日渐频繁。实践中,我国对征用土地的大部分使用都是为了商业目的,而且在征用过程中存在许多有待思考和解决的问题。因此,正确处理经济发展与土地保护的关系,加强对征用土地的监督管理尤为必要。文章通过对土地征用中一些主要问题的归纳和分析,期望完善立法以进一步维护农民的利益,真正实行最严格的土地管理制度,保护和利用好每一寸土地。     

声音的脉动

随着时代的进步,除了音响技术日趋成熟外,音响的种类也越发繁杂.按照类型又可以分为一体式音响以及功放、音响分开式的组合音响;根据箱体声学结构又可以分为密闭箱、倒相箱、无源辐射器音箱、传输线音箱.     

城市与区域关系演化过程及新时代特征

城市与区域关系是定位和指导城市与区域发展的立足点,理清城市与区域关系是实现科学发展的重要保障。分析城市与区域的基本关系及其演化动因和演化过程,以此考察我国传统的城市与区域关系特点,以及全球化与知识经济时代城市与区域关系的新特征和发展趋势,指出我国城市与区域关系处于区域框架指导下的城市主导发展时期;新时期,城市的功能性和区域的整体性是城市与区域关系的核心。在一定时期内,我国城市与区域对立统一关系依然存在,同时,随着城市实体地域与功能地域的空间扩展,城市与区域的边界趋于模糊,城市与区域地理单元走向交织缠绕和相互融合。     

城镇标准地块定位技术探讨

根据重庆市建立标定地价体系的科学实践．提出城镇标准地块空间定位的技术途径为：从分析土地级别内各定级单元土地质量空间分布规律或房地产市场价格空间分布规律入手，采用定级单元总分平衡法和房地产市场价格平衡法确定标准单元，依据功能特征评价成果将标准地块定位。     

INSIDER TRADING: THE LAW, THE THEORY, THE EVIDENCE

This paper reviews the arguments concerning the role and effects of insider trading. In reviewing the law of insider trading, we concentrate on the main elements of the regulatory framework and court interpretations. We discuss economic issues involved in the debate over the benefits and costs of insider trading. Finally, we discuss evidence illustrating that legal market research can explain much of the runup in a target firm's stock price before a tender offer is formally announced.
