本文建立了政府支出创新激励经济增长的理论模型,模型表明政府支出对经济增长的效应取决于预算、投资生产率和支出结构。借助VAR实证模型,中国的经验实证分析表明:公共花费是公共投资的基础,也是GDP增长的主要影响变量;公共投资不一定能促进GDP增长。为此,我们提出政策建议:必须转变政府职能,由投资型政府变为服务型政府,以促进经济持续增长。
This paper establishes a theoretical model of government spending innovation to stimulate economic growth. The model shows that the effect of government expenditure on economic growth depends on the budget, investment productivity and expenditure structure. Empirical VAR models show that the public expenditure is the foundation of public investment and the main influence variable of GDP growth. Public investment may not be able to promote the GDP growth. To this end, we propose policy proposals: we must transform the government functions from an investment-oriented government to a service-oriented government to promote sustained economic growth.
