中文摘要：

江苏旅游经济发展存在较大的空间差异。运用区域经济学中差异分析的方法，分析了江苏旅游经济的总体差异特征，并从旅游构成角度研究了国内旅游、国际旅游的空间分异状况，从空间角度研究了旅游经济差异的地区构成，从时间角度研究了旅游经济差异的变化趋势。在此基础上，从旅游资源禀赋、区域经济发展水平、区位条件、基础设施条件四个方面对差异的内在影响因子进行了阐释，并就江苏旅游经济的协调发展提出了对策。

英文摘要：

With the development of tourism in last two decades, it could be found that spatial differences of tourism economy are gradually formed in Jiangsu. To make further study, research methods using in regional economics are used to analyze the disparities. First of all, some indices such as Gini index and weighted variation coefficient are used to measure the general differences of tourism economy in Jiangsu. Then, tourism development indices are created to analyze the spatial distribution characters of domestic tourism and international tourism. Third, the differences are decomposed by using Theil index to reveal their inherent structures. The trend of change is also analyzed through the comparison of their development speeds of tourism. Base on the analysis above, the causes of differences are explained by four impact factors - the endowment of tourist resources, the level of regional economic development, the location conditions and the level of infrastructure. At last, solutions to narrow the disparities among regions are suggested so as to make tourism economy develop in Coordination.
