经济增长与环境质量问题已引起众多学者的关注。本文利用中国30个省、市、自治区15年的面板数据检验中国是否存在倒U型的EKC曲线,并且在考虑贸易与投资的基础上,得出如下结论:东部地区存在倒U型的EKC,西部地区存在正U型的EKC,中部地区不存在EKC;外贸依存度与碳排放呈现出显著地正相关关系,FDI对碳排放虽有影响但很微弱;贸易和投资对拐点到达的时间并无影响,但却能够提高拐点到达时的人均GDP水平。
The problems of economic growth and environmental quality have drawn the attention of many scholars. In this paper, we test the 15-year panel data of 30 provinces, cities and autonomous regions in China to test whether there is an inverted U-shaped EKC curve. Based on trade and investment, we draw the following conclusion: There exists an inverted U-shaped EKC in the eastern region, There is a positive U-shaped EKC in the western region, and no EKC in the central region. The dependence on foreign trade shows a significant positive correlation with carbon emissions, but the impact of FDI on carbon emissions is weak. However, there is no time for trade and investment to reach the inflection point But it can raise the level of per capita GDP at the time of inflection point.
