税收、财政支出与内生经济增长

Fiscal Expenditure and Endogenous Economic Growth

构建了基于财政支出、税收的内生经济增长模型,并推导出在给定税收、财政支出政策的变化路径时,经济会达到"竞争性分散均衡",税率与经济增长存在"倒-U"型关系,政府投资性支出与经济增长之间正相关。利用中国省际面板数据进行实证检验显示,在我国经济运行中,总产出、消费、投资、政府投资性支出、税率、利息率、工资水平之间存在长期均衡关系。我国宏观税率为28.63%时达到最优值,政府投资性支出对经济增长率存在正向影响,但不同区域间存在较大差异性。

The paper establishes an endogenous economic growth model basing on fiscal expenditure and taxation. From the model, we can conclude that after giving the changing path of taxation and fiscal expenditure policy, economic will attain competitive decentralized equilibrium. There is an inverse - U relation between the rate of taxation and economic growth, a positive relation between governmental investment expenditure and economic growth. Making use of different provinces panel data in China to test it, it exists a long term equilibrium relation among general output, consumption, investment, governmental investment expenditure, the rate of taxation and interest, wage in Chinese economic system. The best rate of macroeconomic taxation is 28.63 %, There is a positive relation between governmental investment expenditure, however, this kind of effect exists a large regional difference.
