重大事件及对旅游地影响是旅游地理学研究的热点。项目以上海世博会这一典型重大事件为例，延续前期对世博会建设及举办期间所做的调查研究，以中长期视角开展历时性研究。借助多学科理论方法，从不同时间维、空间维、特征维构建研究体系。采用结构方程模型、时空数据模型、系统动力学模型来刻画与表达重大事件对大都市区旅游发展影响的作用机理。综合运用SPSS分析、GIS空间分析、空间句法、位序规模分析、拓扑分析、社会网络分析、DEA分析、趋势分析、事件研究法等多学科的方法，研究世博会对大都市旅游形象、旅游产业布局、旅游流空间格局、休闲游憩空间、旅游市场格局、产业市场结构、产业经营绩效、经济效应等方面的影响，表征与测度重大事件对都市旅游发展影响的中长期效应，揭示其发展演化特征与规律，建立指标模型评价上海世博会的旅游影响。研究在理论上丰富了旅游地理学研究内容；实践上，对于国际性重大事件在我国可持续发展具有重要意义。

Mega event and its tourism impact is becoming the focus of research in tourism geography. Taking the typical mega event-Shanghai World Expo as an example, continuing the preliminary studies during the Expo construction and holding period, the project will carry out a diachronic study from the medium and long-term perspective. With the multi-disciplinary theoretical methods, the project constructs the research content system from different dimensions of time, space and characteristics; takes structural equation model(SEM), event-based spatiotemporal data model (ESTDM),system dynamics model(SDM) to describe the mega event tourism impacts mechanism; uses SPSS to analyze the impact of the Expo on tourist destination image; adopts GIS spatial analyst tools, spatial syntax, social network analysis to discuss the impacts of the Expo on tourist industry distribution, tourism flow and recreational space pattern; on the basis of SCP paradigm, the project takes time series analysis, data envelopment analysis(DEA), sequence scale analysis to discuss the impacts of the Expo on tourist industry market structure; uses event study, time series model, background trend line, data envelopment analysis(DEA) and other methods to analyze the effects of mega event on tourist industry performance, tourism market structure and economy. The project represents and measures the medium and long-term effect of mega event on urban tourism development, reveals its development evolution characteristics and the rules, and constructs the index model to evaluate Shanghai World Expo tourism impact. The study enriches tourism geography research content in theory and practically has the vital significance on the sustainable development of the international mega events in China.
