政府公共支出结构与内生经济增长——基于省际面板数据的分析

Public Expenditure Structure and Endogenous Economic Growth:Empirical Study with Cross-provincial Panel Date

政府公共支出是社会经济正常运行的必要条件,对于促进经济增长和社会稳定具有重要的作用,不同的公共支出结构会对经济增长产生不同效果,对这类问题的研究有利于合理安排公共支出结构,从而保证其实现经济稳定发展的目标。本文将我国的公共支出分成经济建设类支出、社会性支出与一般性支出三类,并在一个内生增长框架下探讨了这三类支出对经济增长的影响,然后利用我国1997-2010年的省际面板数据进行实证分析,发现经济建设类支出和一般性支出对经济增长存在负效应,社会性支出对经济增长存在正效应,我国地方公共支出结构存在失衡现象,而且东、中、西部的公共支出结构存在不同的经济增长效应,最后在此基础上结合我国实际情况,提出了公共支出结构优化的建议。

Public expenditure plays a very important role in economic growth, studies on the relationship between the composition of public expenditure and economic growth are favorable for a more reasonable arrangement of public expenditure structure, so as to ensure the goal of economic stability and development. Based on an endogenous model, this paper divides the public expenditure to three categories： economic construction expenditure, social expenditure and regular expenditure, and then discuss the effect of different categories on economic growth. In order to make empirical studies about the different effects, we use panel date from 1997 to 2010 in China to examine the linkage between Chinese local public expenditure structure and local economic growth. The empirical analysis indicates that local economic construction expenditure and regular expenditure negatively impact local economic growth while social expenditure bear positive effect on local economic growth, furthermore, the local public expenditure structures of different regions such as eastern China, middle China and western China have different effects on the local economic growth. Finally, we give some suggestions to optimize the structure of public expenditure base on the above research work and Chinese actual situation.
