| Abstract: | With recently continuous increasing requirement for electric power in China, the power grid scale increases continuously, and the investment to power grid construction increased dramatically. Regarding the power grid con- struction investment as a input/output entitle, this paper, by using the Data Envelopment Analysis （ DEA ） method, analyzes and evaluates the power grid construction investment benefits in 15 years in China. Based on comparison of investment benefits in years, the reasons of the low investment benefits are analyzed by calculation of the slack varia- ble and redundant variable in the paper. |
