The Tourism Interaction between Shanghai and Provinces in the Yangtze River Valley
上海与长江流域各省区间的旅游互动

With the Shift-share Method, the international visitor arrivals statistical data and sampling survey data from 1999 to 2005 of Shanghai and the provinces of the Yangtze River Valley(YRV) have been analyzed, indicating that the contribution of structural shifted components plays a leading role, and the contribution of share components plays a fundamental role in the in-flow and out-flow tourist increment in the provinces of the YRV from or to Shanghai. The competitive shifted components also make contributions but their effect is obviously less than other components. Generally, the structural shifted components and the share components highly concentrate in Shanghai's two neighboring provinces of Zhejiang and Jiangsu, showing a highly regional agglomeration;however, as for the component contributions to the in-flow and out-flow tourist increments in Shanghai, there exists disproportionality in influence in the various provinces of the Yangtze River Delta. To be more specific, the intensity of tourist flow from Shanghai, from east to west, shows a U-shaped distribution. In addition, although the spatial distance is an important factor affecting the change of spatial difference of tourist flow, the regional differences of tourism resource endowment, traffic, characteristics and supply of tourist products and the regional tourism integration, are the fundamental causes affecting tourism interaction between the metropolis and its region, and the change of tourism spatial distribution. It is strategically important to develop regional tourism by promoting the tourism interaction between the metropolis and its region in different spatial scales, so as to realize harmonious development and improve tourism spatial efficiency in China.
