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。
China’s commitment to reducing emissions must rely on the improvement of carbon emission efficiency and total factor productivity. The author selects the panel data of 30 provinces (autonomous regions and municipalities) from 2000 to 2014 in our country, and uses the three-stage DEA model to make an empirical analysis of the carbon emission efficiency and total factor productivity of all regions in China. The results show that, overall, the comprehensive technology efficiency of the 30 provinces and autonomous regions examined is low, the comprehensive technology efficiency in the west is the highest, and the pure technical efficiency in the east is the highest. The technical efficiency of the east is higher than that of the central and western regions, while that of the west is higher than that of the central region. China’s eastern, central and western technological progress in decreasing order. Meanwhile, total factor productivity in the east is also higher than in the central and western regions. In the future, China can take measures such as increasing investment in scientific research, encouraging technological innovation and application, optimizing industrial structure, improving energy structure and raising the level and level of opening to the outside world so as to improve China’s carbon emission efficiency and total factor productivity.
