AN ANALYSIS OF SPACE-TIME DYNAMIC EVOLUTION AND DISLOCATION OF INBOUND TOURISM BASED ON TYPICAL CITIES——WITH THE GRAVITY MODEL AS AN EMPIRICAL RESEARCH
选取60个典型城市，利用引力模型分析1998-2008年中国入境游客和外汇收入的重心位置与动态变化，发现两者存在空间错位且均呈东移南移趋势。
According to the performance of inbound tourism,this paper selects sixty typical inbound tourism cities to research development of China inbound tourism.Owing to annual statistical data of quantity of inbound tourists and inbound tourism foreign exchange income of these typical inbound tourism cities,with the gravity model,it gets center of gravity of China inbound tourists and center of gravity of China inbound tourism foreign exchange income from 1998 to 2008.Due to Google Earth,it discovers locations of each center of gravity from 1998 to 2008.Furthermore,it indicates that each center of gravity is different from the other.Besides,process of the dynamic change of gravities can be shown thanks to this software.Afterwards,it analyzes the phenomenon of space-time dislocation of centers of gravity to reveal the rule of regional space-time dynamic evolution.As a result,research shows that the center of gravity of China inbound tourists in nearly a decade roughly locates in junction of Henan Province and Anhui Province,both of which lie in middle part of China.In addition,the center of gravity of China inbound tourism foreign exchange income in nearly a decade roughly locates in junction of Anhui Province and Hubei Province,both of which lie in middle part of China too.Obviously,there is a phenomenon of dislocation between these two centers of gravity while both of them have a trend shifting eastwardly and southwardly constantly.
