我国经济开放对政府规模的影响研究

Research of Impact of China's Economic Opening on Size of Government

经济开放对政府规模的影响机制一直是学术界的研究重点,目前主要有"效率论"和"补偿伦"两种观点。利用2000—2014年中国31个省(区、市)的面板数据,研究近15年我国经济开放与政府规模的关系。采用静态面板数据模型的实证结果表明,经济开放与政府规模之间呈不确定的关系,且结果不显著;采用动态面板数据模型,即利用差分GMM和系统GMM克服内生性问题后,实证结果表明经济开放与政府规模呈正向关系,即经济开放促使政府规模扩大。同时经济开放与政府规模也存在空间相关性,空间杜宾模型的回归结果显示,相邻地区经济开放对本地区政府规模存在空间溢出效应。

The impact of economic openness on the size of the government has been the focus of academic research and there are two main theories as ＂efficiency＂ and ＂compensation＂. Using data of 31 provinces （regions and cities） of China from Year 2000 to Year 2014, the relationship is studied between economic openness and the size of the government over the past 15 years. Empirical results of static panel data model show. that the relationship between economic openness and the size of the government is uncertain, and the results are not significant. Using the dynamic panel data model namely difference GMM and system GMM to overcome endogenous problems, empirical results show that economic openness is positively correlated with the size of the govern- ment, which shows that economic openness expands the size of the government. There is also a spatial correlation between economic openness and the size of the government. The results of the space Durbin Model shows that economic opening of neighboring regions has a space spillover effect on the size of the regional government.
