本文依据中国“低成本”竞争模式,基于“要素价格”和“多产出”的双约束,构建一种新型的全要素能源生产率指数,并沿着“要素价格-成本权衡-区域能源效率变化”的逻辑链条,从成本视角对全要素能源生产率指数解构,探寻中国区域能源效率的时空分布特征以及根本动因,研究表明:1)要素价格扭曲的“低成本”策略通过技术效率和要素配置效率影响全要素能源生产率的变动,且后者逐渐成为影响我国区域全要素能源生产率指数变动的关键因素.2)就全国而言,能源利用效率和能源配置效率在节能减排政策实施前后有显著的跳跃性增长,说明市场化进程加快、节能减排政策实施能显著提高我国整体能源利用效率和配置效率.3)东部地区能源利用效率表现较好,但因要素市场扭曲程度较高,能源配置效率相对较低;中西部地区技术水平较低,但要素市场扭曲程度相对较小,短期内市场化改革决定的要素配置效率对区域全要素能源生产率提升更重要。
Based on the competition pattern of “low cost” in China, this paper constructs a new type of total factor energy productivity index based on the dual constraint of “factor price ” and “multiple output Cost trade-off - the regional energy efficiency change ”logic chain, from the cost perspective of total factor energy productivity index deconstruction, to explore the spatial and temporal distribution characteristics of China’s regional energy efficiency and the underlying cause of the study shows that: 1) "The strategy affects the change of total factor energy productivity through technical efficiency and factor allocation efficiency, and the latter becomes the key factor affecting the change of total factor energy productivity index in our country gradually.2) For the whole country, the energy efficiency and energy allocation efficiency The remarkable increase in the energy saving and emission reduction policies before and after the implementation shows that the marketization process is accelerated, and the implementation of energy conservation and emission reduction policies can significantly improve the overall energy efficiency and allocation efficiency in China.3) The energy efficiency in the eastern region performed better, The factor market has a higher degree of market distortions and a relatively lower energy allocation efficiency; the technology level in the central and western regions is relatively low, but the factor market distortions are relatively small and short Market-oriented reforms in the decision of the allocative efficiency is more important for regional energy total factor productivity improvement.
