本文利用含有非期望产出的DEA模型构建了可用于研究二氧化碳排放绩效动态变化的Malmquist指数.以此为基础,测度了1996--2007年我国28个省区市二氧化碳的排放绩效.并借助收敛理论和面板数据回归模型分析区域差异及其影响因素。研究发现:样本期间我国二氧化碳排放绩效主要因技术进步而不断提高,平均改善率为3.25%,累计改善为40.86%;四大区域的二氧化碳排放绩效有所差异,东部最高,东北和中部稍低,西部较为落后,但差异性有下降趋势。二氧化碳排放绩效存在收敛性;全国范围内。经济发展水平、产业结构高级化程度、能源强度和所有制结构对二氧化碳排放绩效有显著影响.对外开放的影响则不明显。
This paper evaluates the carbon dioxide emission performance of China by the proposed method, Malmquist index, during 1996--2007, and then regional disparity and the factors influencing performance is analyzed based on convergence theory and panel date model. The main results show that carbon dioxide emission performance improved 40.86% over the period with the average increasing of 3.25% and this was mainly driven by technology progress, the performance differences between four regions was found while the convergence of performance was existed, economic development, industry structure, energy intensity and ownership structure had a significant influence on carbon dioxide emission performance, though openness was not.
