Research on the Calculation and Optimization of the Agglomeration Effect of Specialty Groups in Higher Vocational Colleges in China under the Background of High-quality Development

The key to the construction of high-level specialty groups lies in the generation of agglomeration effect. It shows three effects: scale, sharing and innovation. The analysis of 242 samples based on entropy weight TOPSIS method shows that the innovation effect is more prominent than the three, but the overall agglomeration level of specialty groups is not high, and the category difference is obvious. The optimization of agglomeration effect depends on reinforcement of holistic concept, improvement of mechanisms and establishment of quality assurance system.
