能源消耗与碳排量约束下区域技术效率研究

A study of regional technical efficiency in China under the constraint of energy consumption and carbon emissions

充分考虑能源消耗与碳排量对区域技术效率的影响,将能源消耗与碳排量纳入技术无效方程,运用对数型道格拉斯生产函数的随机前沿分析方法(SFA)构建我国区域技术效率的测算模型,利用2005-2011年省际面板数据,从全国和分地区两个层面分别测算了能源消耗与碳排量约束下的区域技术效率,客观分析存在的差异。实证结果表明,资本投入和劳动力投入都呈现正向作用;能源消耗对技术效率有显著的促进作用,但碳排量对技术效率具有显著的阻碍作用;在考虑能源消耗和碳排量约束下我国三个地区的技术效率变化趋势较平稳,且差异较小。

Fully considering the influence of energy consumption and carbon emissions on regional technical efficiency in China, this paper puts energy consumption and carbon emissions into the technical inefficiency equation, constructs the measurement model based on the stochastic frontier analysis of the logarithmically Cobb - Douglas production function, measures the regional technical efficiency in China from both national and regional levels based on the 2005 -2011 inter - provincial panel data, and objectively analyze the existing differences. The empirical result shows that capital and labor inputs are showing a positive effect, energy consumption plays a significant positive role on the regional technical efficiency, carbon emissions has a negative effect on the regional technical efficiency, the change trends of technical efficiency among three areas is relatively stable under energy consumption and carbon emissions and their difference is smaller.
