城乡收入差距与经济增长关系的实证研究——基于中国1978-2007年数据的协整检验与脉冲响应分析

对中国1978—2007年数据的实证研究结果表明：城乡收入差距与经济增长之间存在着长期稳定的双向因果关系：城乡收入差距只在短期内对经济增长产生影响;而经济增长并不会自动导致城乡收入差距的缩小,相反,经济增长在中长期内还会进一步加大城乡收入差距。     

Do regional house prices converge or diverge in China?

This paper aims to test whether the regional house prices are convergent or divergent in China using a monthly panel data set of China’s 70 large and medium-sized cities from July 2005 to December 2010. This issue is closely related to understanding the efficiency of the country-level housing policies made by China’s central government. The test results suggest that the regional house prices in China are generally divergent, and thereby the country-level policies may be inefficient since they do not explicitly take the strong heterogeneity of China’s regional housing markets into consideration. As a consequence, it may be better for China’s central government to further decentralize and devolve its governance toward the housing market to the local governments.     

Unbundling the differences between Psychic and Cultural Distance: An empirical examination of the existing measures

The diversity between the country-scores of Hofstede, Schwartz, GLOBE, Håkanson and Ambos and Dow and Karunaratna is the main focus of this study. To investigate the correlation between the country-scores of these CD (Cultural Distance), pPD (perceived Psychic Distance) and PDs (Psychic Distance stimuli) instruments we apply the Mantel test, a test predominantly used in anthropology and genetics, which can be particularly insightful when examining “distance” data. The matrix correlation findings provide evidence supporting the high diversity between these measures and their lack of consistent results for the same countries. Therefore, despite the similarity between the way of conceptualizing and operationalizing CD that Hofstede, Schwartz and GLOBE share, these CD measures do not report consistent findings. Consistently, the lack of correlation, between the PDs measure of Dow & Karunaratna and pPD of Håkanson & Ambos, indicates the diversity between PD stimuli measures and perceived PD measures. At the same time, while the two Psychic Distance (PD) measures indicate high correlation in some cases, overall they are highly diverse from the CD measures. We argue, therefore, that identical studies could reach significantly different conclusions by simply using different measures of CD,pPD&PDs which then denotes significant implications for the reliability of research findings. Additionally, we point out potential weaknesses of these measures when examining culturally proximate countries and multicultural nations.     

我国地区经济差异与城市化水平关系的实证分析

对改革开放以来地区经济发展水平的差异以及建国以来全国及各省区的城市化的发展进程进行了描述,利用格兰杰因果关系检验,研究我国不同经济发展阶段中城市化水平与经济增长的因果关系, 并采用国际上流行的Panel data方法从多个角度对城市化与地区经济增长的关系进行了分析研究。结论是:城市化水平的提高对于落后地区经济增长的促进作用要高于经济发达地区。     

基于VAR模型的江苏省投资、消费与经济增长实证分析

本文利用江苏省1980年到2007年经济数据,在VAR模型的基础上,运用协整检验、格兰杰因果检验、脉冲响应分析和方差分解的方法对江苏省的投资、消费与经济增长之间的关系进行实证分析。结果发现,投资、消费和经济增长之间具有长期均衡关系,江苏省地区生产总值的增长与投资和消费都具有双向因果关系,消费对经济增长的贡献度比投资更大。因此,通过提高居民收入水平,才能刺激消费,促进江苏经济健康发展。     

Performance and Capital Structure of Privatized Firms in Europe

Abstract

The objective of this paper is to analyze whether there are differences in performance between private firms and recently privatized firms in the European Union, as well as to determine whether ownership (state-owned versus private) and regulation affect capital structure. Focusing on economic reasons that justify privatizations, we analyze whether there are differences between recently privatized state-owned enterprises (SOEs) and private firms in their profitability, leverage and efficiency during the period 1999–2002. Also, we analyze the determinants of the capital structure of these firms. Contrary to previous studies, our results show that privatized firms are not less efficient than firms with private ownership.     

西部地区财政科技支出的经济增长效应

科学技术是第一生产力,科技投入无论是在推动经济增长还是促进社会发展方面,都有着举足轻重的重要作用。通过协整检验、格兰杰因果检验等方法,研究2006年-2020年西部地区财政科技支出对区域经济增长的作用。实证结果表明,西部地区的财政科技支出与经济增长之间存在着长期的均衡关系。因此,应进一步加大及合理安排政府财政科技资金的投入,加强资金监管,提高资金使用效率,更好地促进经济发展与社会进步。
