Measurement and Analysis of Industrial Isomorphism of Kashgar Urban Agglomeration Based on Degree of Grey Incidence Model

City Circle is an important carrier for the future shift of the world economy and plays an important role in promoting the development of regional economy. With the development of the national economy and the introduction of the Silk Road Economic Belt, the Outline of the Thirteenth Five-Year Plan for National Economic and Social Development of the People's Republic of China specifically defined to promote the development of the city circle centered on Lhasa and Kashgar. The Kashgar Urban Agglomeration, locating in the core area of the new Silk Road Economic Belt, is an important node. The coordinated development of the industry is crucial to the development of the overall economy. In this paper, the gray degree of incidence model is used to measure the degree of industrial homogenization in various cities and towns in Kashgar and further analyze the degree of incidence between cities in Kashgar Urban Agglomeration. The results show that the industrial isomorphism of Kashgar Urban Agglomeration is more serious. The degree of incidence between cities and industries in Kashgar Urban Agglomeration is of varying degrees, and the industrial layout of Kashgar Urban Agglomeration needs urgent adjustment.
