摘要
既有文献较少关注民间投资在波特假说实现过程中发挥的关键性作用。本文采用2007—2017年的省级面板数据,通过方向距离函数对中国绿色全要素生产率进行测度。以民间投资为中介变量和门槛变量,研究了环境规制、民间投资与绿色全要素生产率之间的关系,结果表明:(1)环境规制与绿色全要素生产率之间存在“U”型关系,中国处于拐点左侧,只有提高环境规制强度才能促进绿色全要素生产率提升;(2)民间投资的中介效应显著,环境规制与民间投资呈现显著的“U”型关系,加大民间投资能够促进绿色全要素生产率提升;(3)民间投资具有门槛效应,当民间投资水平较低时,环境规制与绿色全要素生产率负相关且不显著,只有当民间投资水平较高时,环境规制才能显著促进绿色全要素生产率的提升,边际效应随民间投资的增长而递增。本文结果表明,民间投资发展是推动“波特假说”实现的必要前提。
The existing literature ignores the close relationship between private investment and the realization of Porter's hypothesis.In this paper,the green total factor productivity is measured by the direction distance function using data from China at the provincial level for the period 2007—2017.Furthermore,taking private investment as intermediary variable and threshold variable,the relationship among environmental regulation,private investment and green total factor productivity is studied.The results show that:firstly,there is a U-shaped relationship between environmental regulation and green total factor productivity,and improving the intensity of environmental regulation can promote the green total factor productivity.Secondly,the mediating effect of“environmental regulation→private investment→green total factor productivity”is significant,and there is a U-shaped relationship between environmental regulation and private investment,increasing private investment can promote green total factor productivity.Thirdly,private investment also has threshold effect,when the level of private investment is low,environmental regulation and green total factor productivity are negatively correlated or not significant.Only when the level of private investment is high,environmental regulation can significantly promote green total factor productivity.The results show that the development of private investment is the necessary premise to promote the realization of Porter hypothesis.
