Study on Spatial Characteristics and Spillover Effects of Urban Tourism Efficiency: A Case of Yangtze River Delta
基于长三角25个旅游联盟城市2004-2010年数据，用改进DEA模型和空间计量方法分析旅游效率的空间特征与溢出效应，发现效率整体上升且存在空间依赖，固定资产和劳动力投入是主要正向因素。
Based on tourism input-output date of 25 tourism alliances cities in Yangtze River Delta from 2004 to 2010,the paper analyzes tourism efficiency,spatial characteristics and spillover effects by use of improved DEA model,ESDA-GIS and spatial econometric model.The results show that:①Overall efficiency of regional urban tourism has presented an increasing trend,mainly due to the enhancement of the tourism scale efficiency.②Overall efficiency,pure technical efficiency and scale efficiency of regional urban tourism have a strong spatial autocorrelation.The hot spots of overall efficiency and pure technical efficiency in urban tourism present shanghai as the centre of spheres spatial structure,and the cold spots are gathering to the north of Jiangxi province and south of Anhui province.The hot spots of scale efficiency in urban tourism are mainly located in the north of Jiangxi province and south of Anhui province,and the cold spots concentrated around Shanghai.③Overall efficiency of urban tourism exists obvious spatial spillover effects and spatial dependence.The input of fixed assets and labor in urban tourism are the major positive impact factor to overall efficiency.By deepening regional cooperation in tourism,integrating tourism industrial chain and optimizing the proportion of input factors it can effectively promote the sustainable and healthy development of urban tourism in the Yangtze River Delta.
