环境污染治理投入与环境污染——基于内生增长的理论与实证研究

Environmental Pollution Control Investment and Environmental Pollution——Theoretical and Empirical Research Based on Endogenous Growth

文章通过构建一个包含最终产品生产部门和人力资本开发部门的内生增长模型,发现在均衡经济中存在最优的环境污染治理投入,以此通过实证来检验环境污染治理投入与环境污染之间的联系。结果表明:(1)环境治理公共投入在国民生产总值中的占比与环境污染之间存在倒U形曲线;(2)我国环境治理投资在GDP中的比重超过1.8%时才能遏制环境污染加剧的情况。进一步,发现"分权通道"不利于环境污染治理投入发挥其治理环境污染的作用。

The article,by constructing an endogenous growth model in the final product production sector and human capital development sector,finds that there is an optimal scale of environmental pollution control investment in the economy.On this basis we analyze the relationship between environmental pollution control investment and environmental pollution through the empirical testing.The test result shows that（1）the inverted Ushaped curve exists between the ratio of public investment in environmental management in GDP and environmental pollution;（2）China can control the situation of the increasing environmental pollution when the proportion of investment in environmental governance GDP exceeds 1.8%.Further,we find that ＂decentralization channel＂ is not conducive to environmental pollution control investment to play its role in controlling environmental pollution.
