Abstract

The invention discloses an industrial leader identification method based on clustering and comprehensive evaluation. The industrial leader identification method comprises a data collection module, an index system construction module, a clustering and sorting module and a result output module. According to the method, indexes describing enterprise experience, scale and business relations are constructed, and an index system for evaluating enterprises is formed; a weighted k-means clustering algorithm and a TOPSIS comprehensive evaluation method are used in a mixed mode, the weight of each index can be automatically estimated in the clustering process, and then the weight is used for calculating the comprehensive score of the enterprise; and finally, descending sorting is performed on the enterprise comprehensive scores, and an industrial leader identification result is output. According to the invention, when the industrial leader is identified, the cooperation relationship among the enterprise basic information, the behavior information and the enterprise is considered, and the industrial leader can be identified more accurately and effectively.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to an industry leader identification method based on clustering and comprehensive evaluation. Background technique [0002] In any industry, enterprises with high prestige, that is, industry leaders, usually occupy a dominant position in the market. They have relatively more resources and rich experience in their field, can effectively control costs and risks, and have higher performance. Identifying industry leaders helps companies seek high-quality partners, and at the same time helps government departments grasp the structure of the industry market, and even people can explore the evolution law of the industry network from the changes of industry leaders. [0003] From the perspective of complex network analysis, identifying industry leaders is equivalent to finding nodes with high influence in the industrial network. The common method of measuring the influence...
