中文摘要：

旅游业通常被认为对地方经济有促进作用,然而对这种作用很少从旅游者旅行模式的角度进行分析,旅游线路模式导致的旅游经济影响的空间差异要远大于游客活动分布的空间差异。文章以651条国内长途团队世博旅游线路详细报价单为基础数据,结合长三角城市地理空间背景条件,比较分析了旅游线路模式中基于线路节点特性的旅行模式、角色、功能、停留时间与旅游花费,对世博线路中的旅游目的地合作圈层进行了划分,深入探究基于旅游线路模式的长三角城市目的地旅游经济收益的空间差异。研究发现：（1）充分了解并建立与其他目的地的合作关系将从中受益。（2）目的地节点在各客源地旅游线路模式中的角色和功能不同,旅游收益存在显著差异,因此,应有针对性地在不同客源地进行差别化的旅游宣传和营销。（3）整个旅行时间长度是影响游客在目的地区域扩散模式的主要因素,也影响地区间经济利益的分配。目的地日花费与旅行天数呈U形曲线拟合,基于线路中目的地停留时间和花费的估算,长三角地区的旅游经济收益存在着显著的空间差异。该研究的实践意义在于为各目的地进行客源市场定位、宣传与营销提供参考。

英文摘要：

It is generally acknowledged that the tourist industry is able to provide a significant impetus to the local economy. However, this role is rarely analyzed from the point of view of the tourists＇ traveling patterns. Although there is a growing body of literature concerned with the analysis of multiple destination travel and the relevant tourist dispersion, the economic effect on the destination from the perspective of the tourists＇ travel patterns is sti｜l relatively poorly studied. The spatial variation of economic effects is often larger than the differences in the spatial distribution of tourist activity. With a final attendance of more than 73 million, the 2010 Shanghai World Expo was the most successful exposition of its type ever held. It brought considerable tourism benefits to the Yangtze River Delta Area, especially to Shanghai and its neighboring destinations. However, this study has found that there was a wide discrepancy in tourism income from the Shanghai World Expo among the different cities of this region. This study is based on a statistical analysis of the Shanghai World Expo itinerary quotations of 651 travel agencies that were drawn from the key regions of Beijing, Guangzhou, Xi＇ an and Chengdu. The destinations＇ cooperative relationship and their economic discrepancy have been explored according to travel pattern, node role, length of stay, and the tourists＇ daily expenses in the destination area. First, this study has found that the city destinations will benefit from cooperation, which is based on their in- depth mutual understanding. Cooperative marketing opportunities exist and these cities are able to develop a series of attractive tours linking other neighboring destinations. This cooperative promotion will be beneficial for all involved. Meanwhile, it is recommended that the destinations should jointly promote touring itineraries with places that may currently be considered as competitors. Second, different city destinations have different benefits because of their varying
