Introduction  This paper aims to describe all kinds of key points and key factors in cost management of distribution network project, and also provide reference for further normalization and standardization of future cost management work of distribution network project.

  Method  We checked a lot of literature materials, summarized advanced experience of several typical developed countries in pricing system and cost management model, and discussed some problems in project management and cost management of China′s distribution network project.

  Result  The results show that the cost management methods of distribution network projects are not uniform, and the pricing rules are complicated. The accuracy and timeliness are ineffective, then there offen appears "data barriers" and "information islands" phenomenon.

  Conclusion  Finally, combining with the actual requirements of distribution network project cost management, this paper put forward that whole-process and intelligent are the inevitable trend of cost management development in the future. It also suggests several rationalization proposals, which includes promoting intelligent and digitalized development of distribution network project cost, improve the pricing basis, creating a favorable market environment, strengthening whole-life cycle cost management and fine enterprise management.
