摘要

The investment for distribution network is an important part of power grid construction. The establishment of the analytical model for the investment efficiency of the distribution network construction is able to ensure the efficiency and reliability of the power system and is one of important means to realize the intensification of the grid construction. This paper has established a data envelopment analysis model to assess the investment efficiency of grid enterprises. For less objectivity of the original model, an entropy weight method has been introduced to determine the weight of each index. At the same time, a normalization method has also been brought in the model establishment to achieve the standardization of the index value so that the model is more scientific and accurate and its practicality has been proved by the analysis of examples.
