The dissertation consists of 4 parts, the main content and conclusion follows as:The first part introduce the five structuring models of natural monopoly industries,This part analysis the structuring practice policy of developed country;Based on it,This part describes the innovation policy of electrical industries inchina ,Also, appraises the innovation scheme of electricity industry and indicates it is the advancement to electricity industry regulation and accord with the international innovation direction of electricity industry. Meanwhile, this part point out the shortage of the innovation scheme of electricity industry, based on it, the author gives some advice on how to reform the electricity industry regulation system continuously.The second part study the pricing rule and the economic efficient under the input competition and the downstream monopoly based on the innovation of electrical industry .At first this part study the bidding and the franchisebidding between upstream competition coporation.Then this part study the option contract of electrical industry under the produce ability substrain.The third parts mainly study the acess price under vertical market. The part main study the acess pricing under the upstream monopolist exert no price discrimination strategy and can not exert no price discrimination strategy,Also this part study the investment strategy of upstream monopoly by use of the real option theory under the acess competition.The forth parts describe the innovation phrase of electrical monopoly industries in china,Based on it ,This part investigate the economic efficience of electrical distribution Co.in ChongQing by use of the data enveolopment analysis(DEA),It shows,because of the regulation ,The electrical distribution Co.in ChongQing is no effieience.The following is the main contributions of the dissertation:â‘ The dissertation study the optionmal access pricing under the upstream monopoly firm exert no price discrimination strategy and can not exert no price discrimination strategy, The study shows, under the no price discrimination,when the cost of tranfer payment to upstream monopoly firm is higher,The optimal access price is more than the margine cost,others,The optimal access is less than the margine cost.â‘¡The author make use of the Nash subgame equibrium theory, constructuring A two-period, three-person entry game model, which explicitly includes second-best government, the study shows, when the entrant cost is high, The free-entrant euuibrium number is greater than the socialoptimal equibrium number, So the entrant regulation is necessary; Meawhile,because of the competion affection, The incumbent monopoly firm can not execute monopoly pricing, as it ,The competion can improve the efficience.â‘¢The dissertation study the investment strategy under the access competition, and comes to conclusion: the upstream monopolists motives investment to enlarge scale is relation to the capacity level of the competioner , When the competioner'capacity level is bigger, the motives is less,others the motives is more;Meanwhile,The dissertation study the investment movties of upstream monopoly firm under no competion, The study shows, The regulation price is less, The movties is less,others,The movties is higher.
