With the deepening of power system reform, the precise investment and lean development of power grids have become the focus of power grid enterprises. It is of great significance to carry out evaluation research on the efficiency of input and output of effective assets of power grids. Based on the analysis of the status quo of effective asset evaluation in China’s power grid, this paper combines the model of super-efficient DEA with the analysis of effective asset output efficiency of power grid to construct an evaluation system of effective asset input and output efficiency of power grids, and takes the national power grid as an example for calculation and analysis. This paper objectively evaluates the internal and external factors affecting the efficiency of the effective assets of the grid, and provides quantitative analysis support for the effective asset investment decision of the grid.
