人民币汇率波动对NFDI波动的影响及其检验

本文通过对我国NFDI资本流动性及其波动性的计算,检验了人民币/美元汇率波动对NFDI波动性的关系。通过实证分析表明,人民币汇率的波动将导致NFDI资本流动的明显不稳定。在理论研究的基础上,引申出其政策含义：在国际资本流动不断加大的今天,我们必须维护人民币/美元汇率的稳定,这样对于有效引导NFDI的资本流动和维护金融稳定都具有重要的意义。     

Trade‐led growth hypothesis in Cuban commercial regimes since 19601,2

This study examines the impact of trade on Cuban growth during different commercial policy regimes spanning the period from 1960 up to 2004, encompassing two essential economic structural transformations: the Cuban revolution and the fall of the Berlin Wall. For this purpose, the Granger causality is used by means of the modified Wald test for augmented‐level vector autoregressive model with integrated and cointegrated processes introduced by Toda and Yamamoto (1995) and Dolado and Lutekepohl (1996) . We show an import‐led growth hypothesis during the Soviet‐oriented pattern that is rejected after 1990, when exports are not only responsive to growth expansion but also to imports’ behaviour.     

黑龙江省耕地非农化与经济发展的Granger因果关系研究

研究目的:分析黑龙江省耕地非农化过程的内在原因,以助于协调黑龙江省耕地非农化进程与经济发展的关系,使耕地保护工作与未来经济运行相一致。研究方法:运用Granger因果关系检验法,利用Eviews4.1软件分析。研究结果:城市化进程对耕地非农化进程的影响与经济增长对耕地非农化的影响并不一致,城市化进程对耕地非农化的影响更加显著。因此,要从根本上解决耕地非农化与经济发展之间的矛盾须将城市化作为切入点。     

略论土地环境与土地问题

本文拟从土地环境的角度切入，探讨土地利用、保护和管理的途径。界定了土地环境的概念，分析了其构成体系和基本特征；探讨了土地自然环境、工程环境和社会环境对土地的影响，并结合我国的实例，对原生土地问题、次生土地问题和社会土地问题进行了探索性研究。     

城市住宅价格与宏观经济变量的关系分析——基于VAR模型的实证研究

通过分析选取住宅价格指数(HPI)、国内生产总值增长率(GDP)、1-3年期银行贷款利率(IR)作为内生变量,滞后两期的广义货币供应量(M2)作为外生变量,建立了向量自回归模型。并在此基础上,运用协整分析、脉冲响应函数、方差分解和格兰杰因果检验等研究方法对住宅价格指数与宏观经济变量之间的动态相关关系进行了研究。研究结果表明,我国的住宅价格与所选用的宏观经济变量之间存在一定交互响应作用,并就此提出了相关建议。     

Further evidence on finance-growth causality: A panel data analysis

This paper reassesses the causal relationship between financial development and economic growth. Using recently developed panel methods on a data set of 71 developed and developing countries over the period 1960-2004, our study confirms previous results of a bidirectional causality between finance and growth. In addition, we show significant differences among country groups when considering both long-run and short-run causality. While in low and middle income countries there is no supportive evidence of short-run causality between financial development and economic growth, in high income countries economic growth significantly affects financial development.     

上海市外贸发展与经济增长关系实证研究

通过统计计量分析发现,上海对外贸易规模较大且增速较快,对外贸易与经济增长关系密切,二者存在长期稳定的均衡关系,外贸总额或者进口额每增长1%,则GDP将增长0.5%以上。但是,外贸总额、出口额、进口额增长并不是上海经济增长的格兰杰原因,恰好相反,经济增长是短期外贸总额、出口增长的格兰杰原因。     

A Study on Strategic Value Chain and Cost Driver and PEST Analysis Method

Strategic value chain analysis method can be adopted to analyze the existing cost causality so as to confirm and optimize the value chain. Strategic cost driver analysis method that is used on the income of the owners and daily operators, production and operating activities, administration, resources, culture, etc in an enterprise can further enlarge the strategic cost scope. For analysis of the enterprise and its external environment factor, PEST analysis is represented as the extroversive analysis of cost causality. Three analytical methods of different kinds having some commonness on cost causality analysis can be combined together to form the causality analysis method, which will expand the visual angle of analysis and help to establish the integral frame of strategic cost causality analysis.     

Information flows within and across sectors in Chinese stock markets

We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.     

论我国货币供应量中介目标的有效性

以普勒基本分析理论为基础，对我国经济的基础冲击进行了两阶段实证分析，结果表明目前的冲击仍然主要来自于商品市场；分析了货币供应量与真实GDP之间存在着长期均衡关系，认为货币供应量作为中介目标仍然具有理论上的合理性，但是合理性并不一定意味着效率性，进而通过Granger因果检验对货币供应量的低效性进行了证明。在实证分析的基础上对上述问题的产生原因进行了分析。
