| Due to the difference of local economic development level,tourism resources endowment,population density and other factors,as well as the diversity of geographical characteristics in different regions of China,there are huge differences in the level of county tourism economic development and the mechanism of influencing factors of development is also complex and diverse.At the same time,under the influence of the externality of economic activities,the development of tourism economy also has spillover effect to some extent.Among the existing studies on the differences of tourism economic development in China,there are few studies on county-level,and there are still many possibilities for micro-scale studies.This paper intends to explore the spatial-temporal differences and spatial effects of county tourism economy in Jiangsu Province,and analyze the factors affecting the development of tourism economy at the micro-scale,so as to provide suggestions and Countermeasures for promoting the efficient and healthy development of county tourism economy.This paper takes the total tourism income of 72 spatial units in counties of Jiangsu Province from 2007 to 2016 as the research object.By analyzing the existing geographical spatial pattern and historical causes of the counties in Jiangsu Province,using ESDA and quantitative analysis methods,and on the basis of summing up relevant theories and existing achievements,this paper explores the spatial-temporal differences and spatial effects of the county tourism economy in Jiangsu Province,and draws the following conclusions:Firstly,during the decade 2007-2016.the overall pattern of tourism economic development in Jiangsu counties showed obvious spatial dependence,and the regions with similar development level gathered and distributed in space,and the agglomeration gradually increased;the tourism economy in Jiangsu counties south of the Yangtze River showed obvious polarization and spillover effects,and the tourism economic development in the north of the Yangtze River lacked obvious core and hot spots.The difference of regional tourism economic development level between north and south of the Yangtze River is gradually enlarging;the spatial pattern stability and self-organization of county tourism economic development in Jiangsu Province are gradually increasing;the spatial difference of tourism economic development between the two counties of the Yangtze River is large,showing a dual pattern of North-South development.Secondly,the county tourism economy in Jiangsu has a significant spatial spillover effect.Economic development level,tourism resources endowment and population size are the important factors affecting the development of county tourism economy in Jiangsu.There is a significant spatial correlation between the tourism economy of a specific county unit and the tourism economy of its neighboring units.Thirdly,the spatial weight matrix of Jiangsu County Tourism economy,which incorporates historical and geographical factors.can more effectively describe the spatial correlation among county units in Jiangsu.The main contributions of this paper are as follows:Firstly,taking the total tourism income of Jiangsu County spatial unit as the research object,the paper explores the spatial and temporal differences of county tourism economic development and enriches the research results of the spatial and temporal pattern of micro-scale tourism economic development.Secondly,based on the existing methods of constructing spatial weight matrix,this paper uses exogenous construction method and prior knowledge to incorporate the historical and geographical factors of county development in Jiangsu into the construction and revision of spatial weight matrix,which is more close to the national conditions and provides a new idea for the construction of spatial weight matrix of other similar problems. |
