Current electrovalence of our country has adopted the fixed price method taking cost as basis ， electrovalence system has included unitary system such as making with two system and leading adjustment ， the peak valley electrovalence strenuously ， the main body of a book has been studied by the fact that the method forming mechanism ， fixed price to current electrovalence draws with electrovalence system carding ， has discussed the motivation on the economy adopting current electrovalence policy with effect ， has taken that 09 Xu Zhou area year electric power consumes condition as example and， The metastasis going deep into the pattern having studied current mistake unites fixed price having led to being unlike industry ， being unlike area and so on compensates effect and achievement an The metastasis studying content makes the electrovalence and the difference electrovalence mainly including two compensates an That research method is one， is that general welfare comes to estimate that the metastasis compensates achievement an effect by analysing consumer surplus ， producer surplus and society ， two is to take the average electrovalence that current electric power sells as criterion electrovalence ， analyses the consumer electric charge differences of all kinds to criterion The proportion studying result indicates an electrovalence ， liang of headquarter makes if reasonableness ascertains fundamental electric charge and electricity degree electric charge， can raise the surplus providing power consumption both sides ， improves general welfare of society and The consumption coefficient of elasticity is different to the difference electrovalence ， every industry ， every region electric power because of power consumption ， adopt the different electrovalence， not bad bigger limit's the electric power consumption promoting every industry ， every region consumer， can raise the surplus providing power consumption both sides ， improves the public welfare and efficiency But be unable to return back reasonableness completely at present， with economic growth ， the economic pattern adjustment if two proportion ， electrovalence differences being unlike industry making the middle fundamental electrovalence electrovalence and the electricity degree electrovalence are horizontal， our country electrovalence structure has very big improvement The data calculation should consume a coefficient of elasticity with every industry electric power and counting concretely is Adjusting architectural ultimate electrovalence purpose is a potentiation ， improves welfare， the main body of a book has been produced
