本文主要研究了公共产品供给与经济增长和区域收敛的关系,从理论上阐述了公共产品供给对经济增长收敛的作用机制;通过构建经济增长收敛模型,选择1998～2009年中国31个省(自治区、直辖市)公共产品供给的面板数据,采用GMM的方法进行计量分析。实证结果表明,公共产品供给显著促进经济增长,并有利于区域经济收敛,考察期我国区域经济收敛速度为3%～3.08%。建议国家在公共品供给政策设计上应充分重视公共品在经济增长中的内生性作用,增加落后地区公共产品供给,并且在公共产品的供给上政府应处于主导地位,以市场机制为基础,政府和市场分工互补来提高公共产品的供给效率。
This paper mainly studies the relationship between the supply of public goods and economic growth and regional convergence, expounds the mechanism of public goods supply on the convergence of economic growth in theory, and constructs a model of economic growth convergence to select the economic growth of 31 provinces (autonomous regions , Municipalities) public product supply panel data, the use of GMM method for measurement analysis. The empirical results show that the supply of public goods can significantly promote economic growth and is conducive to regional economic convergence. During the period of investigation, the rate of regional economic convergence in China is between 3% and 3.08%. It is suggested that the state should pay due attention to the endogenous role of public goods in economic growth and increase the supply of public goods in backward areas. The government should take the leading position in the supply of public goods. Based on the market mechanism, the government And market division of labor complement each other to improve the efficiency of the supply of public goods.
