摘要
电网企业因其垄断特性造成的成本信息不对称性,不仅制约了政府对电网企业监管的效率,而且使消费者对电价定价缺乏信任,因而,评估电网企业的成本合理性具有重要的理论和现实意义。从空间对标视角,以中国国家电网公司各分公司的运行维护费为样本,采用Gini准则融合多种DEA模型的测算结果,并进行空间系统聚类分析,结果表明:①全国大多数省级电网公司运行维护费支出处于合理水平,但部分电网企业的分量成本合理性水平较低;②运营绩效水平较高的公司存在更高的绩效提升边际成本,较容易发生成本的支出不合理;③各电网公司在选择成本对标标准时,既要选择成本合理性程度较好的公司作为参照,又要依据动态参考原则随时调整合理成本的参照系。
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.
