基于异质性假设的我国二氧化碳排放影响因素分析

Impact Factors of Carbon Dioxide Emission in China Based on Heterogeneity

比较准确地测算了我国29个省份的二氧化碳排放总量和人均排放量,并根据人均排放和收入,构建省级二氧化碳排放异质型面板,利用动态面板数据模型研究我国二氧化碳排放EKC曲线及影响因素.实证结果显示,高收入和低排放低收入地区的经济发展水平与二氧化碳排放量存在倒"U"型关系,环境库兹涅兹曲线假说成立.经济和产业结构、能源消费、国际贸易和城市化水平等是我国二氧化碳排放的重要影响因素.另外,我国二氧化碳排放表现出明显的路径依赖现象.

CO2 emissions of 29 provinces in China are calculated accurately in this article and analysed comparatively in four different areas,high-income ones with high emission,high-income low emission,low-income high emission and low-income low e mission. Meanwhile,in the framework of dynamic panel data model,what influences carbon dioxide emissions are also investigated here. The results indicate that the hypothesis of environmental Kuznets Curve is established,according to the inverted U-shaped re lationship that lingers between the level of economic development and CO2 emissions except the area of low-income high emission.Significant positive influence has been proved by energy comsuption,the level of urbanization and foreign trade. In addition,an obvious phenomenon of path dependence is evidently expressed.
