【摘要】：本文采用1999—2010年中国的分省面板数据从竞争、产权改革和管制政策三个维度来检验经济体制改革对电力行业产出效率的影响,从单因素效应、多因素效应以及其间的交互关系三个方面分析改革政策对于行业增长的相对重要性。基于工具变量法的实证研究表明:(1)在单因素模型中,产权和管制政策变量具有显著的正向效应,而竞争效应不显著;(2)在改革政策的联合模型中,产权和管制政策的作用相对重要,竞争正向效应的显著性提高;(3)改革政策间的交互关系均对产出绩效具有负向影响,表明改革政策间的配套效应尚未实现预期效果。以上结果在不同的指标设计和模型设定下均是稳健的。本文的研究结论具有明显的政策启示:深化电力体制改革应当继续推行厂网分开和主辅分离,确立市场在电力资源配置中的决定性作用;在进行改革设计时需要兼顾考虑改革变量的相对重要性和其间的交互影响,全面评估改革措施的作用效果。
[Abstract]:In this paper, the panel data from 1999 to 2010 in China are used to test the effect of economic system reform on the output efficiency of power industry from the three dimensions of competition, property right reform and regulation policy, and from the single factor effect. This paper analyzes the relative importance of reform policy to industry growth from three aspects: multifactor effect and interaction. The empirical research based on instrumental variable method shows that: (1) in the single factor model, the property rights and regulatory policy variables have significant positive effect, but the competition effect is not significant; (2) in the joint model of reform policy, The role of property rights and regulatory policies is relatively important, and the positive effect of competition is significantly improved. (3) the interaction between reform policies has a negative impact on output performance, indicating that the matching effect between reform policies has not yet achieved the expected effect. The above results are robust in different index design and model setting. The conclusions of this paper have obvious policy implications: deepening the reform of power system should continue to carry out the separation of power plant and power system, and establish the decisive role of the market in the allocation of power resources; It is necessary to consider the relative importance of the reform variables and the interaction between them, and to evaluate the effect of the reform measures in an all-round way when carrying out the reform design.
