Abstract: How to dispose the cross-subsidy of electricity price properly has become a key issue in advancing the reform of electric power system. In order to analyze the mechanism of electricity price cross subsidy intensively, this paper takes the demand price elasticity used into its theoretical model to introduce a classification standard for cross-subsidy of electricity price based on Opening Form. It founds that:compared with cross-subsidy among regions, cross-subsidy among different users distort the electricity price much more serious in China; and the Generalized Preference and Price-boosting Effect have caused the benefit spillover problems of electricity price cross subsidy. It provides theoretical support for precisely grasping the key issues of dealing with electricity price cross subsidy.

Key words: demand price elasticity, cross-subsidy of electricity price, electricity price distortion, spillover effect
