以长三角城市群26个城市为基本研究单元,选用泰尔指数对该区域近15年的旅游经济发展进行了定量测度。结果显示:城市群旅游经济总体差异不断缩小,呈相对均衡化发展的趋势,省域内、等级城市内部差异是影响总体差异演变的重要原因;江苏和浙江旅游经济的内部差异逐渐缩小,安徽旅游经济的内部差异有扩大倾向;中、小城市和2010年至今的超大及特大城市旅游经济的内部差异呈扩大之势,大城市旅游经济的内部差异在缩小。据此从高速铁路网建设、旅游产品开发、体制机制构建等方面,对长三角城市群旅游经济的协同发展提出了相应的对策建议。 Taking 26 cities in the Yangtze River Delta as the basic research unit, we use the Theil index to quantitatively measure the tourism economic development in the past 15 years in this region. The results show that the overall difference of tourism economy in urban agglomeration is decreasing, presenting a relatively balanced trend of development. The internal differences among the cities in the province and the rank are the important reasons that affect the evolution of the overall difference. The internal differences of tourism economy between Jiangsu and Zhejiang are gradually getting smaller. The internal differences of tourism economy in middle and small cities and from 2010 to present have widened. The internal differences of tourism economy in metropolitan cities have been narrowing. Based on this, some countermeasures and suggestions for the coordinated development of the tourism economy in the urban agglomeration of the Yangtze River Delta are put forward from the aspects of the construction of high-speed railway network, the development of tourism products and the construction of institutional mechanisms.
