Study on the comprehensive assessment system of distribution network construction project input-output benefit

Aiming at the problems that the scale of distribution network investment is gradually increasing and the investment effectiveness still needs to be improved, the paper propose a comprehensive assessment system of input-output benefit for distribution network construction project. Firstly, select input-output benefit indexes basing on key factors. Secondly, propose index evaluation criterion determining method. Then, present a method to calculate input-output benefit for distribution network construction project. Finally, the instance analysis results demonstrated the effectiveness of research results.
