我国区域碳排放效率与全要素生产率研究——基于三阶段DEA模型

Research on Regional Carbon Efficiency and Total Factor Productivity in China——Based on a Three-Stage DEA Model

我国实现减排承诺必须依赖于碳排放效率和全要素生产率的提高。笔者选取我国30个省(区、市)2000年~2014年的面板数据,运用三阶段DEA模型对我国各地区的碳排放效率和全要素生产率进行实证分析。结果表明:总体上看,所考察的30个省区市综合技术效率偏低,西部的综合技术效率最高,东部的纯技术效率最高。东部的技术效率要高于中西部,而西部又高于中部。我国东、中、西部技术进步依次递减。同时,东部全要素生产率也高于中西部。未来我国可以采取增加科研投入、鼓励技术创新与应用、优化产业结构、改善能源结构、提高对外开放的层次与水平等措施来提高我国碳排放效率与全要素生产率。

At present, if our country wants to achieve carbon emissions reduction, we must rely on the improvement of efficiency and total factor productivity. This article selects the panel data of 30 provinces （municipalities directly under the central government） in Chi- na during 2000 - 2014, and makes empirical analysis using three-stage DEA model. The results show that the comprelaensive technical efficiency is low in the examined 30 provinces. The comprehensive technical efficiency of the western region is the highest, and the pure technical efficiency of the eastern region is the highest. The eastern region is higher than the central and western region on technical efficiency, while the western region is higher than the central region. The technological progress is decreasing from the eastern to the central and western in China. At the same time, the total factor productivity in the east is higher than that in the central and western regions. To improve the efficiency of China＇ s carbon emissions and total factor productivity in the future, our country can rely on increasing research investment, encouraging technological innovation and application, optimizing industrial structure, improving the energy structure, improving the level of opening up.
