FDI对于二氧化碳排放的门槛效应——来自省际面板的证据

Threshold Effect of FDI on Carbon Dioxide Emission:Evidence from Provincial Panel Data

基于1999—2012年我国30个省份的数据,从门槛面板分析角度,以收入门槛和研发投入门槛为切入点,检验FDI对于二氧化碳排放影响的门槛效应,实证结果表明,FDI对于二氧化碳排放具有显著的门槛效应。收入门槛表明,在低收入阶段FDI对二氧化碳排放有显著促进作用,而在中等收入和高收入阶段FDI则具有减排效果。研发投入门槛表明,研发投入可以显著地降低二氧化碳的排放量,但随着研发投入的增加,减排效果降低。因此,地方政府应该积极应对FDI迅猛增加的现状,加快研发投入,完善节能减排政策,促进经济发展转型。

This paper focuses on the threshold effect of FDI on carbon dioxide emission,based on data of thirty provinces in China from 1999 to 2012. From incomeand R＆D threshold perspectives,empirically examined whether the existing threshold effects or not. The resultshows that there is significant threshold effect of FDI on carbon dioxide emission. From the income threshold perspective,FDI will promote carbon emission in lower income stage,and will reduce emission in middle and high stage. From R＆D perspective,we find that its expense will reduce carbon emission significantly,but the effect declines with the increase of its input. So in order to positively deal with the situation of rapid FDI growth,local government should increase R＆D input,perfectthe policy of energy saving and emission reduction and accelerate the development of economy.
