中文摘要：

以长江三角洲地区16个城市的旅游经济发展为研究对象,采用标准差、变异系数等方法分析其总体差异及年际变化趋势,利用首位度方法分析城市旅游规模结构演化,揭示旅游经济发展时空分异演化规律,并围绕旅游资源禀赋、社会经济发展水平、交通条件解析长三角地区旅游经济时空分异影响因素.研究发现：（1）长三角地区旅游经济呈现绝对差异扩大、相对差异减小态势.上海旅游的中心性是导致区域旅游经济差异的主因,初现以上海为中心,杭州、南京、苏州为次级旅游发展中心的主-副中心旅游圈层结构;（2）长三角地区各市旅游经济发展水平与旅游产业地位初现空间分异性,即错位型和匹配型;（3）长三角地区入境游客日趋分散,逐渐由中心城市向外扩散.

英文摘要：

Taking the tourism economic development of 1 6 cities in the Yangtze River Delta for the study obj ect,the overall economic difference of tourism economy and the changeable tendency of 1 6 cities in the Yangtze River Delta are analyzed by means of standard deviation, variation coefficient and other methods.Primary index are also used to analyze the structure of tourism scale, and study the spatial and temporal evolution of tourism economy development. Simultaneously,the factors affecting tourism economy in time and space are fully explained in terms of tourist attraction resources,level of socio-economic development and transportation. Research found that （1）In the Yangtze River Delta,absolute differences of tourism economy are gradually enlarging while relative differences are gradually reducing as a whole.And prominent central position of Shanghai in tourism mainly results in differences between Shanghai and other cities.Specifically,the spatial structure comes into form in which Shanghai being the center ,and Hangzhou,Nanjing,and Suzhou acting as sub-centers;（2）There exist spatial differentiations, that are dislocation type and matched type,between tourism economy development level and status of the tourism industry in Yangtze River Delta;（3）Inbound tourists of the Yangtze River Delta decentralized increasingly,and it is gradually spread outward from the center of the city.
