空间集聚、经济增长与环境污染之间的门槛效应分析

An Analysis of Threshold Effect on the Relationship between Spatial Agglomeration,Economic Growth and Environmental Pollution

文章通过构建面板门槛模型检验了空间集聚、经济增长与环境污染之间的内在机制。结果表明,集聚对经济增长的作用受到开放性的影响,随着贸易开放度的逐步加深,集聚对经济增长的促进作用将不断凸显。同时,空间集聚对经济增长的非线性关系使得环境污染排放与经济增长之间表现出倒U或倒N型关系,表明适度集聚规模是实现生态环境与经济增长双赢的关键,环境库兹涅茨曲线假说是否成立取决于集聚程度。

This paper builds a panel threshold model to test the internal mechanism of spatial agglomeration, economic growth and environmental pollution. The results show that the effect of agglomeration on economic growth is affected by open- ness, and with gradually deepening trade openness, the effect of agglomeration on promoting economic growth will continue to highlight. Moreover, the nonlinear relationship of spatial agglomeration and economic growth makes economic growth and environmental pollution also present ＇inverted U-shape＇ curve or ＇inverted N-shape＇ curve, which indicates that the appro- priate agglomeration scale is the key to achieve a win-win of eco-environment and economic growth, that is, the degree of agglomeration is an important factor affecting whether environmental Kuznets curve hypothesis is satisfied.
