摘要: 我国电价交叉补贴问题非常严重,其无论从经济效率还是公平上而言都是不合理的,必须尽快解决。通过对现行电价政策分析,阶梯电价政策可以解决交叉补贴问题,但现行方案效果不明显,因此需要调整。不仅如此,由于各档次用户对电价变化的需求响应程度存在差异,调整阶梯电价来解决交叉补贴的方案有许多,故存在一个社会福利最大化的解决方案。本文以社会福利最大化为目标,调整各档用户的电价,同时引入拉格朗日函数,设计出最优解决交叉补贴问题的阶梯电价方案,得到各档相应的电价比值。结果表明,当分档电价比值为1:1.62:2.41时社会福利存在极大值,此时阶梯电价方案是众多方案中的最优方案,社会福利全年增加约为702.00亿元。此方案在解决交叉补贴问题的基础上还兼顾了用户间公平和承受能力,对当前电价改革具有重要参考价值。

Abstract: The problem of cross-subsidy of electricity price in China is very serious, which is unreasonable in both economic efficiency and fairness. By analyzing the current electricity price policy, it is found that the tiered pricing for electricity can solve the cross-subsidy problem, but the effect of current scheme is not obvious, and it needs to be adjusted. What's more, due to the difference in the demand response degree of users of different grades, there are many schemes to solve the cross-subsidy problem by adjusting the tiered pricing for electricity. And there is a solution to maximize social welfare. The aim of this paper is to maximize social welfare, adjust the price of electricity for each file user, and at the same time introduce the Lagrange function to design an optimal electricity price plan for solving cross-subsidy problems and obtaining the corresponding electricity price ratio for each file. The results show that social welfare has a maximum value when the ratio of the block tariff is 1:1.62:2.41. At this time, the ladder price scheme is the optimal one among many schemes, and the social welfare increased by about 70.2 billion yuan for the whole year. The fairness and affordability among users on the basis of solving cross-subsidy issues are considered in this solution. It has important reference value for current electricity price reform.

Key words: cross-subsidy, block tariff, demand response, social welfare maximization
