| 摘 要： 基于中国2001—2014年的省际面板数据，采用超越对数形式的随机前沿模型，对中国TFP的组成进行了分解研究。结果表明，2001—2014年，TFP年均增长率为1.64%，TFP增速总体呈现持续下降趋势。其中，技术进步年均增长率为0.84%，技术效率年均增长率为-2.50%，规模效率年均增长率为3.43%，配置效率年均增长率为-0.12%。总的来看，我国仍然处于规模报酬递增阶段，规模效率增长是正向影响我国TFP变化的主要因素，但是2011年后增速大幅放缓。技术效率则是负向影响我国TFP的主要因素，这也证明当前通过供给侧改革去落后产能的重要性。分省情况来看，东部地区的技术进步和配置效率已经越过转折点开始进入缓步提升阶段，而中西部仍然在负增长徘徊，证明了东部地区有可能率先实现增长动力转换。 |

| Abstract: Based on the cross-province panel data of 2001-2014 in China, and by using stochastic frontier analysis (SFA), this article analyzed the change of TFP and its components. The results showed that, during the period of 2001-2014, the average annual growth rate of China’s TFP was 1.64%, showing a downward trend. Among them, the average annual growth rate of technical progress was 0.84%, technical efficiency was -2.50%, scale efficiency was 3.43%, allocative efficiency was -0.12%. Overall, China is still at the stage of increasing returns to scale, and scale efficiency growth is a major factor in the positive impact on China’s TFP change. But after 2011, efficiency growth slowed down significantly. Technical efficiency is the main factor of negative impact on China's TFP. This shows the importance of the current supply side reform to backward production capacity. By region, the technology progress and allocative efficiency in eastern region has been crossed turning point started to the promotion stage. But central and western region is still in negative growth hovering. It is proved that the eastern regions are likely to be the first to achieve growth engine conversion. |
