为什么我国电网定价折旧率不能简单参照国际经验取值

Why China's Regulatory Depreciation Rate of Fixed Assets of Power Grids Should Not Be Simply Determined by Referring to International Experiences

政府对输配电价实行成本加收益管制,输配电成本是监管的重点内容之一。为此,国家发展和改革委员会正组织制定《输配电价格成本监审暂行办法》,其中,有人建议参照有关国际经验,将电网企业的定价折旧率定为5%。折旧对电网企业的影响,尤其是对电网建设资本金的影响,非常重大。本文从经济折旧理论入手,结合国内外经济发展和电力工业发展情况,深入分析了我国电网定价折旧率不能简单参照国际经验取值的理由,并提出了政策建议。

Since the government regulates transmission and distribution tariffs with the cost-plus method and that the transmission and distribution costs are one of the major regulatory issues, the NDRC （the National Development and Reform Commission） is now arranging for establishment of the ＂Provisional Measures for Supervision on Pricing and Costs of Power Transmission and Distribution＂. It is suggested that a depreciation rate of 5% should be set for grid enterprises considering relevant international experience. Depreciation has great impacts on power grid companies, especially on their capital for power grid construction. Therefore, on the basis of the depreciation theory in economics and considering the development of the international economy and the electric power industry, we thoroughly analyzed in this study the reasons why the depreciation rate of fixed assets should not be simply set out by indiscriminatingly referring to international experiences, and we also put forward some recommendations for policy makers.
