| In recent years, China has obtained a rapidly development of cultural industry, gradually becoming a pillar industry of national economic development. With the extensive application of new technologies, the new type of cultural industry has been derived, forming different types of cultural industries agglomeration areas. Based on the cultural resources and the demand of economic development in Xi'an, cultural industry has become one of the five pillar industries. But due to the heterogeneity of urban space, the continuation of urban historic space characteristics, the difference of market demand, and the cultural industry policy, the development of cultural industry is uneven, clustering in certain area. The research about clustering mainly concentrated in the administrative unit scale, while the research about culture industry and contrast research involving different types within administrative unit fresh.Under the research results, the study takes the culture industry of Xi'an as the research object, defining the meaning of spatial heterogeneity about cultural industry based on the theory of spatial heterogeneity in the field of ecology and economics. It takes the latest "culture and related industry classification (2012)" standard as the basis of the types, and makes various types cultural industry as the sample, firstly abstracting cultural industry data as point pattern data, using kernel density estimation, nearest neighbor clustering analysis, Ripley's K function methods to analyze the spatial characteristics of cultural industry in Xi'an; secondly abstracting cultural density as he numerical map, using the relative spatial heterogeneity index, semi-variation function to analyze the heterogeneity characteristics of cultural enterprise's density value in space; thirdly abstracting cultural enterprises density as types map, using the diversity index of cultural enterprises to analyze the spatial heterogeneity of the diversity of cultural enterprises, and to simulate the spatial pattern of the diversity of cultural enterprises; finally explaining the reasons for the spatial heterogeneity of cultural industry in Xi'an.The following conclusions can be obtained from what have been analyzed above:(1) The Space characteristics of cultural industry in Xi'anFocusing on the number of cultural enterprises, the distribution of cultural enterprises is uneven, presenting "center-periphery" layout. And they mainly distribute differently among The Beltway within Zhangjia Village Street, Changan Road Street in Beili County and Xiaozhai Road Street, Zhanga Road Street, Electronic Town Street, Changyan Fort Street in Yanta County; Cultural enterprises and various types present an phenomenon which they cluster in space. But the aggregation degree of every type of enterprises is different, forming the corresponding cluster hot area. The highest aggregation degree exists in radio and television movie services while the minimum in crafts production enterprises. Hot spot areas are mainly distributed nearly in integrated urban development center, business development center, university and scientific research institutions, as well as the traffic trunk; The agglomeration of the spatial distribution on cultural industry based on types are different, all appearing peak at 4.4-7.4 km. And the scope of spatial location of cultural enterprises based on types are different.(2) The spatial heterogeneity characteristics of cultural industry in Xi'anFocusing on density of cultural enterprises, through the calculation of space heterogeneity index, the difference in the county is smaller than the difference in the street based on the cultural industry and different types of culture enterprises; By the statistical characteristic in density of cultural enterprises, the change degree in density of cultural enterprises is gradually small with the increasing grid scale; Spatial heterogeneity of density is fitted with a spherical function model. The density of the culture enterprises is clustering in the space, and the degree of the density of the culture enterprises becomes smaller with the increase of distance before becoming a constant; The isotropic analysis shown that the range of spatial auto-correlation is different among different grid scale, which is mainly focused on 4-10km; In addition, 1*1km grid scale is optimal dimensions to research spatial heterogeneity in the diversity of cultural enterprises, through the cultural enterprises diversity variation analysis. By Kriging interpolation, high density value of cultural enterprises diversity mainly distributed near the center of the Clock Tower-the South gate, the business district of Xiaozhai village-Zhangba Road.(3) The reason why cultural industry spatial heterogeneity exists in Xi'anThe spatial heterogeneity of culture industry mainly includes the factors in the social history, market demand, external economies of industry scale and industry Association, technology and talents cultural industry policy in Xi'an. |
