【 摘 要 】

The three-stage DEA model was applied to study the investment efficiency of a power grid enterprise (PGE) under the reform of electricity transmission and distribution price. This research indicates that environmental variables, including GDP Per Capita and the proportion of industrial power consumption, have a significant impact on the investment efficiency of PGE. To be specific, GDP Per Capita and the proportion of industrial power consumption have a positive influence on the investment efficiencies of PGE in this research. Without environmental variables and random errors, the main reason for the low investment efficiencies of PGE was the lack of scale efficiency. In order to improve its investment efficiency, PGE should attach great significance to economies of scale and a reasonable plan of the enterprise scale.
