中文摘要：

在测算我国1997～2007年间省级CO2排放量的基础上,通过对面板数据单位根检验及协整检验,并以此建立面板数据环境库兹涅兹曲线（EKC）模型,研究全国及东、中、西部地区CO2排放量与经济增长、产业结构及能源消费结构之间的相互关系。实证结果表明,考察期中全国和东部地区EKC曲线呈倒N型,中、西部地区CO2排放量则随人均GDP单增,工业比重及煤炭消费比重的降低都将导致CO2排放量的减少

英文摘要：

Based on the measurement of Chinese provincial CO2 emissions from 1997 to 2007,this paper constructs panel data Environment Kuznets Curve（EKC） model based on root test and cointegration test of the panel data unit,and studies the relationship between CO2 emission and economic growth,industrial structure and energy structure of the whole China and east,middle and west regions.The empirical results show that,the EKC of the whole China and east region are inverted N,while CO2 emissions of middle and west regions increase as per capita GDP increases.Meanwhile,reducing industrial proportion and coal consumption proportion will reduce CO2 emission
