The Integration of China's Tourism Industry and three Industries and It's Spatio-temporal Evolution
Industrial integration is an important means to implement the comprehensive tourism and build a modern tourism economic industrial system. Based on the entropy method,grey relational model and exploratory spatial data analysis method,this paper constructs an evaluation index system for the integration of the tourism industry and three industries and discusses the integration of the tourism industry and three industries and it's spatio-temporal evolution characteristics. The results showed that: ①From 2002 to 2016,the degree of integration between the tourism industry and three industries has gradually deepened in all provinces and autonomous regions,but there are significant differences.The integration with the primary industry transitioned from medium integration to medium-high integration; the integration with the secondary industry has been maintained in the medium integration stage; the integration with the tertiary industry has evolved from medium integration to high integration. ②The integration of the tourism industry and three industries in each province and region presents positive autocorrelation features in the global space,but the autocorrelation features are different. The agglomeration of tourism industry and the first and third industries highlights the spatial agglomeration characteristics,and the degree of spatial agglomeration deepens. The spatial distribution of integration with the second industry continues to maintain the agglomeration status,and the extent of agglomeration does not change significantly. ③The fusion of tourism industry and the three industries in each province has certain regularity in the local space. The integration with the primary industry basically presents a spatial distribution pattern of"high in the east and low in the west". The spatial distribution of the HH areas is centered around the Bohai Sea and fluctuates from south to north; the fusion with the secondary industry takes place from North China and East China to the West. The spatial pattern of gradual decline in the southwestern region; the fusion with the tertiary industry to present the distribution pattern of "high in the east and low in the west". However,due to the economic crisis in 2008,there was a temporary and discrete development in the HH areas.
