人力资本、物质资本财政支出与经济增长——基于内生增长理论的分析

The Public Expenditure of Human,Material Capital and Economic Growth——Based on the Analysis of Endogenous Growth Theory

本文基于内生经济增长模型研究我国物质资本、人力资本财政支出对经济增长的影响,研究发现当任何一项财政支出比例占总财政支出比例较低时,在总财政规模不变的前提下,增加该支出比例能促进经济增长;当这项支出比例占总财政支出比例较高时,减少该支出比例能促进经济增长。本文利用2007-2014年我国财政数据,进一步考察了物质资本、人力资本财政支出与经济增长的关系,结合模型发现,人力资本财政支出低于最优值,物质资本支出高于最优值,适当提高人力资本支出和降低物质资本财政支出比例有利于促进经济增长。

This paper discusses the economic growth effect of public expenditure including material capital and human capital in endogenous economic growth model. The author finds out that increasing the proportion of one kind of expenditure could promote economic growth as this kind of expenditure takes relatively low proportion of total expenditure on the premise of fixed fiscal size. At the same time,decreasing the proportion of one kind of expenditure could promote economic growth as this kind of expenditure takes relatively high proportion. Using fiscal data from 2007 to 2014 in China,the relationship between public expenditure and economic growth has been investigated. Compared with the optimum amount under the model,the amount of human capital expenditure is lower and material capital expenditure is higher,so relatively higher human capital expenditure and lower material capital expenditure benefit the economic growth.
