Study on Spatio-Temporal Differences in Coupling Relationship Between Chinese Inbound Tourism and Import Trade During 1993 to 2010
借鉴物理学耦合理论，构建评价模型，定量评估1993-2010年中国31个省份入境旅游与进口贸易的耦合协调度，发现两者协调发展，且东部优于中西部，南方优于北方。
This paper used coupling theory in physics for reference,analyzed the function mechanism of coordinated development between inbound tourism system and import trade system,constructed coupling evaluation model and index of two systems,used improved entropy method to quantitatively evaluated coupling coordination degree of 31 provinces of China’s Mainland during 1993 to 2010.By clustering,separating and comparing coupling coordination degree between inbound tourism and import trade form 1993 to 1998,1999 to 2004 and 2005 to 2010,several conclusions can be drawn as follows:the inbound tourism and import trade share a interaction and harmonious development with a coupling coordination;the coupling coordination degree level of southern region was more superior,the polarization trend of coupling coordination degree in northern region was more notable;the whole coupling coordination degree level of eastern region was more obviously superior than middle and western region’s;the coupling coordination degree diversity of middle region was lesser than others,the polarization trend of coupling coordination degree was more notable in western region.
