本文在构建电网公司市场势力模型的基础上，经测算得到2004-2013年（除2009年）黑龙江、吉林和辽宁三省在各年度的市场势力具体数值。通过将辽宁省电力公司市场势力的变化情况与其他两省进行比较．首次尝试利用综合对比法探究削弱辽宁省电力公司市场势力的主要原因．即辽宁省抚顺铝厂的大用户直购电试点政策。进一步测算得出．在相同时间段内辽宁省抚顺铝厂大用户试点政策引致辽宁省电力公司各年的福利变动，以此揭示直购电政策是有效的市场化手段。同时。本文显示了自2004-2013年三个省级电力公司申报核算的年度固定资产折旧率、电价交叉补贴率与三省电力公司市场势力存在相同的变化趋势．而辽宁省自2009-2013年的趋势变化程度与其他两省有较大差别。据此，将三省电力公司市场势力数值与申报的固定资产折旧率和电价交叉补贴率做计量回归．进而提出规范电网公司固定资产折旧率的核算方式以及均化交叉补贴率的设想．将市场势力“关进笼子”使其不会阻碍政策的推行．为中国电力产业市场化的改革提供理论依据。

This paper constructs the model of market power of State Grid Corporation of China. Then, the paper estimates, from 2004 to 2013 （except 2009）, numerical market power by using of Heilongjiang, Jilin and Liaoning provincial company related data. On the basis of numerical market power, the paper makes a deep comparison of the change of market power between Liaoning province and other provinces, and utilize the method of comprehensive analysis which focus on the effect of Liaoning Fushun Aluminum Plant large customers direct power purchasing policy to Liaoning province electric power company. The result presents significantly weaken effect of market power, subsequently, the paper estimates the welfare caused by the change in each year,which points out the policy can be marketization. In the process of calculation and analysis above, the paper found that, since 2004-2013, three provincial electric power companies declare the annum depreciation rate of fixed assets, electricity cross subsidy rate and the two provincial electric power company market power present the same change trend. But the trend of Liaoning province, from 2009-2013, has a great difference with other provinces of degree. Based on this, combined with the above figures provincial electric power company numerical market power, the paper does a regression of market power, fixed assets depreciation rate and electricity price cross subsidy rate. Then, the paper points out the thought of standardize the grid company depreciation rate of fixed assets accounting, and the idea of homogenization cross subsidy rate. Making the market power ＂in the cage＂ will not hinder the implementation of the policy, which will be positive for the reform of marketization of power industry in China.
