That we introduce competition in temporary monopoly area will accelerate the development of water supply industry.The thesis firstly analyzes the technical and economic features of city water supply industry and actuality and problems of city water supply industry in our country. On the basis of this, the article compares three theories that are the theory of franchise bidding,the theory of yardstick competition and the theory of workable competition.
