摘要
通过时空范围的具体化,选择了世博会影响力的一个侧面,研究上海世博会对长江三角洲地区经济的影响,并对其影响力进行定量评估。首先建立了基于主成分分析和聚类分析的初步模型,并在考虑到长三角交通因素和城市农村之间经济辐射效应之后,对初步模型进行了两个方向的优化,建立了两个优化模型。利用这两个模型,对北京奥运会和昆明园博会前后的经济指标变化进行分析,验证模型的正确性。
By specifying time and space,this paper chooses one aspect of the impacts of world Expo,studies and quantitatively evaluates the influence of world Expo on the economy of Yangtze River Delta.The paper first establishes the initial model based on principal component analysis and cluster analysis,then optimizes the models in two directions and establishes two optimized models after considering the situation of transportation and economic radiation effect.With these two models,the paper analyses the changes of economic indicator after Beijing Olympic Games and Kunming Horticultural Exposition in order to test the accuracy of the model.
