Abstract: In order to promote the smooth implementation of energy performance contract (EPC) projects， aiming at existent problems in the process of implementing EPC， such as unsound policies and regulations， market information asymmetry， financial difficulties， lack of effective management of project implementation and operation and maintenance， inaccurate energy-savings forecast， unreasonable distribution and other issues， this article proposes the evaluation index system of EPC projects， which includes five first indicators， such as financial， operational， policy， market， income， and 22 secondary indicators， such as channels of financing， EPC project management capabilities， the bank interest rate adjustments， changes in energy prices， risks of energy companies to pay and so on. It aims to improve the weights of evaluation index based on AHP with the use of entropy method， and carry out evaluations by determining the combined weights.
