Abstract: The spatial effect of tourism economy in China during the period of 2005—2013 was examined. The result shows: firstly, the spatial correlation effect exists in the development of urban tourism economy in China, but there are significant differences along with the changes of threshold value and time. Secondly, under long distance conditions, area difference of the tourism economy development is obvious from the east to the west. Under short distance conditions, big cities, including Beijing, Shanghai and Guangzhou, have high spatial correlation with neighboring cities, and show significant trend of merging development. Thirdly, results of the semivariable function model show the core different area between interurban tourism economies is at northwestsoutheast direction (north by west 79 degree), represented by the line from city of Shanghai to Chengdu. Low and medium difference areas mainly concentrated around Shanghai, Beijing and Guangzhou.

摘要： 以GIS平台的ESDA技术，对我国2005—2013年间337个地级以上城市的距离阈值与旅游收入面板数据进行分析。结果显示：我国城市旅游经济发展存在空间相关效应，随距离及时间变化差异显著。大阈值尺度下，东、西部区域分割现象明显；小阈值下，大城市与近邻城市间融合性发展趋势明显。半变异函数表面值显示，旅游经济的核心差异线以“江浙沪—成渝以西”走向为代表，中低差异线以“北、上、广”三线走向为代表。
