妥善处理交叉补贴问题是输配电价改革的关键环节。本文根据电价交叉补贴测算的相关文献,比较分析了交叉补贴测算方法;并以天津市为例,选择价差法,依据输配电价下的价格形成机制,将测算出的分压销售电价作为基准价格,计算了分电压等级的居民、农业生产享受的交叉补贴额和补贴程度以及工商业及其他用户单位电量需要承担的补贴责任。结果发现交叉补贴严重,占电费收入的10%左右。其中,居民是享受交叉补贴的主要对象,占全社会电价补贴额的90%以上,低电压等级享受的补贴程度要高于高电压等级。本文最后根据输配电价改革政策方向,提出了妥善处理交叉补贴的具体建议。
Properly tackling cross-subsidy issues is a key link in the reform of transmission and distribution tariffs. In this paper, based on the cross-subsidized electricity price estimates of the relevant literature, comparative analysis of the cross-subsidy measurement method; and Tianjin as an example, the choice of spread method, based on price formation mechanism under transmission and distribution prices, the calculated partial sales price as the benchmark price , Calculate the sub-voltage level of residents, agricultural production enjoy the cross-subsidy and subsidies as well as business and other users of the unit of electricity need to bear the subsidy liability. As a result, cross-subsidization was found to be serious, accounting for about 10% of electricity tariffs. Among them, residents are the main target of enjoying cross-subsidy, accounting for more than 90% of the total social electricity subsidies, and the subsidies enjoyed by lower voltage levels are higher than the high voltage levels. In the end, according to the policy of reform of transmission and distribution price, this paper puts forward concrete suggestions for properly handling cross subsidies.
