中文摘要:
      中国是以煤电能源为主体的国家,如何优化能源结构成为供给侧改革中关注的重点。以企业的生产效率为切入点,将中国煤电产业链的纵向一体化细分为煤炭产业的前向一体化和电力产业的后向一体化,依据2002-2017年的微观企业数据,采用投入产出表法计算纵向一体化指数,运用以中间投入为代理变量的半参数估计法测算煤电企业的全要素生产率,进一步构建固定效应面板模型实证分析纵向一体化对企业全要素生产率的影响。研究结果表明:(1)煤炭产业的前向一体化指数与电力产业的后向一体化指数均是波动上升的,但后者上升趋势高于前者。(2)煤电产业链的全要素生产率呈现波动上升趋势,且电力产业的全要素生产率水平高于煤炭产业。(3)煤电产业链纵向一体化政策与企业全要素生产率之间呈现"倒U形"关系,但目前煤、电企业一体化对提高生产效率仍具有积极影响。
English Summary:
      China is a country with coal and electricity sources as the mainstay. How to optimize the energy structure has become the focus of supply-side reform.Taking the production efficiency of enterprises as the starting point,the vertical integration of China's coal-electricity industrial chain is subdivided into the forward integration of the coal industry and the backward integration of the power industry. Based on the micro-enterprise data from 2002 to 2017,the vertical integration index is calculated by the input-output table method,and the TFP of coal and electricity enterprises is measured by the semi-parametric estimation method with the intermediate input as the proxy variable. And further construct a fixed effect panel model to analyze the impact of vertical integration on enterprise TFP. Research indicates:(1)The forward integration index of the coal industry and the backward integration index of the power industry both fluctuated,but the latter's upward trend was higher than the former.(2)The TFP of the coal-electricity industrial chain shows a volatility,and the TFP of the power industry is higher than that of the coal industry.(3)The vertical integration policy of coal-electricity industrial chain has an "inverted U-shaped" relationship with the TFP of enterprises. However,the integration of coal and electricity enterprises still has a positive impact on improving production efficiency.
