The asymmetry of grid corporations' cost information caused by their monopolistic characteristics, not only restricts the effectiveness of government supervision, but also leaves consumers with little trust in electricity pricing. Therefore, it is of great theoretical and practical significance to evaluate the reasonable level of cost expenditure of grid corporations. From the perspective of spatial benchmarking, taking the operation and maintenance costs of different branch companies in state grid corporation of China as study samples, this paper uses Gini criterion to fuse the results calculated by various DEA models, and then conducts a spatial hierarchical cluster analysis. The results show that: First, the total cost of operation and maintenance in most provincial grid corporations are at reasonable level, while the component cost of some provincial grid corporations are not. Secondly, corporations with higher operating performance level have higher marginal cost of performance improvement, which makes it easier to incur unreasonable cost expenditure. Thirdly, when choosing cost benchmarking standards for different grid corporations, we should not only choose the corporations with higher reasonable level of cost expenditure as reference, but also adjust the frame of reference system at any time according to the principle of dynamic reference.
