【摘要】 在分析我国电力行业改革现状的基础上 ,结合我国电力工业的特点 ,运用交易成本理论分析我国电力行业“厂网分开、竞价上网”改革前的内部交易成本和在完全电力市场条件下的市场交易成本 ,并用图像和数学相结合的方法对这两种成本进行刻画和定量比较 ,最后将比较的结果基于经济学原理进行数学分析 ,得出了电力行业“厂网分开”改革的经济学条件 :即电厂处于规模报酬递增时 ,这种改革是没有经济意义的 ;在规模报酬递减阶段 ,这种改革也应分步骤逐步实行。更多还原

【Abstract】 This paper analyzes interior transaction cost before the reform of separation of network operations and generation, and making electric generation market competitive in power industry, and market transaction cost in complete power market with the theory of transaction cost in china on the basis of the actuality and characteristic of Chinese power industry,then the describtion and the scalar comparisim are done between two costs by curve and mathematics. Based on the economic theory,the authors analyze the compare result,and come out the economic term of separation of network operations and generation in power industry, that is to say that there isn’t economic reason when the electric plant lies in the phase of scale reward increasing by degrees,on contrast,when the electric plant lies in the phase of scale reward decreasing by degrees,the reform should be done step by step.更多还原
