居民收入视角下中国农村能源碳排放效率问题研究

Research on the Efficiency of Rural Energy Carbon Emission in China from the Perspective of Residents'Income

基于2006—2020年中国30个省份的面板数据,采用超效率SBM模型对我国农村能源碳排放效率进行测度,在此基础上,运用泰尔指数考察居民收入权重下我国农村能源碳排放效率区域差异及其演变特征,并通过面板Tobit模型分析居民收入水平与农村能源碳排放效率的非线性影响关系。结果表明:(1)我国农村能源碳排放效率总体呈波动上升趋势,省域间有较大差异且存在扩大趋势。(2)我国农村能源碳排放效率泰尔指数值总体呈波动上升态势,区域内差异大小以及各区域差异对全国总体差异的贡献度排序均为“东部>西部>中部”。(3)居民收入水平对农村能源碳排放效率具有正向影响作用,从影响程度来看,中部地区最明显,东部地区次之,西部地区较弱。

Based on the panel data of 30 provinces in Chinese mainland from 2006 to 2020,the Super-efficiency SBM model is adopted to measure the carbon emission effciency of rural energy in China.On this basis,Using Theil Index to investigate the regional differences and evolution characteristics of rural energy carbon emission efficiency under the weight of residents'income,the nonlinear influence relationship between residents'income level and rural energy carbon emission efficiency is analyzed by panel Tobit model.The results are:(1)China's rural energy carbon emission efficiency is generally fluctuating and rising,there are big differences among provinces and there is an expanding trend.(2)The Theil Index of China's rural energy carbon emission efficiency is generally fluctuating and rising,and the order of regional differences and their contribution to the national overall differences is"Eastern>Western>Midlands".(3)Residents'income level has a positive impact on rural energy carbon emission efficiency.From the perspective of the degree of impact,Midlands is the most obvious,followed by the Eastern,and the Western is weak.
