Regional Disparity,Affecting Factors and Convergence Analysis of Carbon Dioxide Emission Efficiency in China:On Stochastic Frontier Model and Panel Unit Root
中国政府在“十二五“规划中明确提出了二氧化碳减排的目标,由此引来的亟待解决的问题是:在促进结构调整的同时如何兼顾落后地区的发展空间？客观地评估和分析我国不同地区二氧化碳排放效率的现状,趋势及其影响因素是解决这一问题的先决条件。本文在随机前沿边界分析框架下,直观地定义并测算了碳排放效率,然后对我国1995~2009年各个地区的碳排放效率进行测算,并对地区差异、影响因素及收敛性进行分析。研究结果表明碳排放效率存在比较大的地区差异,而且这种差异还会不断扩大,地区差异始终是我国减排政策实践中应当考虑的因素。此外,发挥市场的资源配置作用、城市化进程、清洁能源的替代、出口贸易的发展等对我国碳排放效率的提高有积极的促进作用。Chinese government proclaimed a target of the reduction of carbon dioxide emission in the 12th Five-Year Plan,which led the urgent problem how to give consideration on the development of less developed areas while concentrating on promoting the structural adjustment.It is a requirement of the problem that objectively evaluates and analyzes the present situation,the trend and the affecting factors of carbon dioxide emission efficiency in different areas in China.Under the framework of stochastic frontier analysis,this paper directly defined the carbon emission efficiency,measured the carbon emission efficiency in each area of China from 1995to 2009,and analyzed the regional disparity, affecting factors and convergence.The results show that carbon emission efficiency has obvious regional disparity,which may continue to expend,and always is a factor should be considered in the practice of China's reduction policy.In addition,resource allocation,urbanization,clean energy substitution,export trade development have positive effects on the promotion of carbon emission efficiency.中央高校基本科研业务费专项资金(项目编号:201122G008)资
