An Analysis Of The Spatial Spillover Effects Of Tourism Economic Development In The Pan-Yangtze River Delta Since 2000

China's tourism economy has developed rapidly since the 21st century.Because of the different times of starting tourism development,unlike tourism resources and uneven government policies,the spatial difference of tourism economy is widespread.Along with the scholars to the regional tourism economic research deepening,the concern to explore the interrelationship among regions is very keen.The problems of unbalanced development of regional tourism and spatial spillover have become increasingly prominent.In this paper,Geographically Weighted Regression(GWR)is used to expand ordinarily linearity regression by embeding spatial data structure into the regression model for explaining the driving factors that affect the development of tourism economy.The research area selected in this paper is Pan-Yangtze River Delta,including Jiangsu province,Zhejiang province,Anhui province and Shanghai.The Pan-Yangtze River Delta is the most developed area in tourism economy around the country.There are large spatial differences in the internal tourism economy.The spatial pattern and the evolution process of tourism economy in Pan-Yangtze River Delta have been analyzed.Based on reading literature,(1)this thesis used scale variance from two aspects of provincial and municipal to find that the tourism economy of prefecture-level city is more different and there is a growing tendency.(2)Through the barycenter model,we found that tourism economic center of the Pan-Yangtze River Delta region is east-west.And in the time period of this study,the spatial difference of tourism economy has an expanding trend in the northwest direction.(3)Using geostatistics studied the spatial pattern and development process of tourism economy in Pan-Yangtze River Delta.(4)Through the analysis of the markov chain,this paper studied the transfer status of tourism economy types in various cities.(5)According to the analysis of the spatial markov chain,the tourism economic situation of the surrounding region has certain influence on the regional tourism economic development.The spatial spillover is divided into positive and negative directions.(6)By using the GWR,the driving factors affecting the development of tourism economy are explored.Tourism resources,income level and economic level have great influence on the development of tourism economy,and the level of transportation,education level and investment level also have some influence on the development of tourism economy.
