目前关于研究环境库兹涅茨曲线EKC的大多数文献都存在同质性的假定,但是这不能够很好地解释个体间的经济结构或资源禀赋差异,所以本文利用1995年到2014年省级面板数据分析,首先按照非参数估计得到函数形式;其次按照面板门限回归对各省份进行划分,从而解决异质性的问题。基本结论是:(1)EKC的3次曲线形式要比2次曲线的更好;(2)从各省份的情况来看,除了上海和北京处在“双重红利”局面,其他省份处于“双增”的不利形势;(3)影响CO2排放量的主要因素是能源因素(EI、ES)、人口因素(PD)、工业化(IP)、城市化(UL)。
At present, most of the literature about the EKC of the research environment Kuznets Curve has the assumption of homogeneity, but this does not explain the economic structure or the resource endowment difference very well. Therefore, in this paper, Panel data analysis, first according to non-parametric estimates of the function form; followed by panel threshold regression provinces to divide, in order to solve the problem of heterogeneity. The basic conclusions are: (1) EKC’s third-order curve is better than the second-order curve; (2) From the situation in each province, except that Shanghai and Beijing are in “double dividend”, the other provinces are in (3) The main factors affecting CO2 emissions are energy (EI, ES), population (PD), industrialization (IP) and urbanization (UL).
