将碳排放引入全要素生产率分析框架之中,利用Malmquist指数对长江经济带2000~2013年的全要素碳生产率进行测算。实证研究结果显示:(1)从时间维度来看,在此期间长江经济带碳生产率一直处于震荡上升的趋势,而全要素碳生产率处于较平稳的状态,年均增长率为2%;(2)从空间差异来看,长江经济带上中下游碳生产率区域差异明显,下游>中游>上游,全要素碳生产率下游区域高于中上游区域,而中游区域和上游区域则处于“追赶-超越-被反超”的状态;(3)上游区域全要素碳生产率增长的动力为技术效率的提高,中游区域全要素碳生产率平均下降了0.1%的原因为技术进步恶化的幅度已经完全抵消了技术效率提升带来的变化,下游区域主要是通过技术创新推动最优生产前沿向外移动使得全要素碳生产率平均增长了4.4个百分点;(4)安徽和贵州两地碳生产率提高的空间最大,而云南、四川和重庆地区也可通过技术进步、技术创新促进碳生产率的提高,上海、浙江、江苏和江西的碳生产率提升空间最小。
The carbon emissions into the framework of total factor productivity analysis, using the Malmquist index of the Yangtze River economic belt 2000 ~ 2013 total factor carbon productivity calculation. The empirical results show that: (1) From the time dimension, during the period, the carbon productivity of the Yangtze River economic belt has been in a trend of rising shocks, while the total factor carbon productivity has been in a relatively steady state with an average annual growth rate of 2%; (2) ) From the perspective of spatial differences, the carbon productivity in the middle and lower reaches of the Yangtze River economic belt is significantly different from that in the middle and lower reaches of the Yangtze River. In the lower reaches of the middle reaches, the lower reaches of the middle reaches are higher than the middle and upper reaches, while the middle and upper reaches are in the catch-and-surpass (3) The driving force for total factor carbon productivity growth in the upstream region is the increase in technical efficiency. The reason why the total factor carbon productivity in the middle reaches decreased by 0.1% on average is that the rate of deterioration in technological progress has completely offset the increase in technology (4) Anhui and Guizhou have the most room for improvement of carbon productivity, while the lower reaches of the region are mainly driven by technology innovation to move the optimal production frontier outwards, resulting in an average increase of total factor carbon productivity by 4.4 percentage points. (4) Yunnan, Sichuan and Chongqing also boosted carbon productivity through technological advances and technological innovation, boosted carbon productivity in Shanghai, Zhejiang, Jiangsu and Jiangxi Provinces. A minimum.
