In order to meet the requirements of external supervision and support the high-quality development of state grid corporation, this study constructs an efficiency-benefit-oriented investment performance evaluation index system for power grid enterprises from the perspective of “social-economic-technology”. This study builds an evaluation model, investment combination scheme, strategy matrix, and formulates a plan for the breakdown of investment scale to strengthen precise investment and guide the investment plan of the next year. The research focuses on 11 municipal power supply companies in a province and carries out research on investment performance evaluation and the application of evaluation results. The results show that S2 and S1 should adopt the stable growth strategy; S10, S9, and S6 should adopt the benefit quality strategy; S3 and S5 adopt the slow lifting strategy; S4, S7, S8, and S11 adopt the policy support strategy.
