财政支出结构、人力资本积累与经济增长

The Structure of Fiscal Expenditure,the Accumulation of Human Capital and Economic Growth

本文通过构建四部门模型,分析了财政支出结构与人力资本积累对经济增长的作用,研究发现:财政支出结构对经济增长的作用是不确定的,依据公共支出与生产性支出之间的不同比例关系而异;人力资本对于经济增长的作用是不确定的,依人力资本存量存量是否达到一定的临界条件而异,而这一作用的大小受制于教育资金中政府投入比重与财政支出中公共支出比重;基础设施投资与公共卫生支出能促进经济增长,但这一正向效应的大小受制于财政支出中公共支出的比重;政府教育投资有助于经济增长,这一作用的大小与教育投资回报率密切相关。

The article establishes a four-sector model in order to make an analysis on the effect the structure of fiscal expenditure and the accumulation of human capital impose on the economic growth. As the findings show, the structure of fiscal expenditure has an ambiguous effect on the economy, depending on the ratio between public expenditure and manufacturing expenditure. Human capital exerts an uncertain effect on the economic growth, depending on the quantity of human capital achieving a threshold level. However, the effect is constrained by the ratio of governmental investment in education funds and the ratio of public expenditure in the fiscal expenditure. The investment of infrastructure and the expenditure of public health con- tribute to economic growth, but the positive effect is constrained by the ratio of public expenditure in the fiscal expenditure. Governmental education investment is beneficial to economic growth, and the effect is closely related to education investmentreturn rate.
