摘要/Abstract

摘要： 电价交叉补贴具有严重的非效率性和非公平性，其准确计量和对社会福利的影响直接关系到用户的电价水平以及交叉补贴解决机制的设计。电价交叉补贴计量的关键在于基准价格的核定，传统的以成本为基础的计量方法虽然考虑了电力企业的收支平衡，但并不是福利最优的定价结果。沿着需求定价的角度出发，以社会福利最大化为目标，构建了电价交叉补贴的计量模型，模型以用户需求定价和需求函数构建为主要工作。结果表明：交叉补贴和社会福利与用户的自价格弹性、交叉价格弹性以及管制机构的福利权重系数有关。最后，本文通过实证模型准确地计量了各类用户的自价格弹性以及交叉价格弹性，测算了我国电价交叉补贴和对应最优社会福利的大小，验证了模型的准确性和有效性。

Abstract: The current cross-subsidy of electricity price is quite inefficient and unfair, and its accuracy of measurement and influence on social welfare are directly related to the level of electricity price of users and the design of the cross-subsidy settlement mechanism. The key to the measurement of cross-subsidy of electricity price lies in the verification of the benchmark price. Although the traditional cost-based measurement method considers the balance of income and expenditure of power enterprises, it is not the pricing result of welfare optimum. Starting from the perspective of demand pricing and aiming at maximizing social welfare, this paper constructs a measurement model of electricity price cross-subsidy, which mainly focuses on the users' demands pricing and the construction of demand function. The results show that the cross-subsidy and social welfare are related to the users' self-price elasticity, cross-price elasticity and the welfare weight coefficient of the regulatory agency. Finally, this paper accurately measures the self-price elasticity and the cross-price elasticity of various kinds of users through the empirical model, calculates the cross-subsidy of electricity price and the corresponding optimal social welfare, and verifies the accuracy and effectiveness of the proposed model.

Key words: users' demand, cross-subsidy, self-price elasticity, cross price elasticity, social welfare
