长江经济带旅游经济的时空分异及影响因素研究

长江经济带旅游产业的整体协调发展是我国旅游空间格局优化的关键.利用长江经济带11个省市2001年～2017年的面板数据，综合采用地理空间分析和多元回归分析方法研究区域旅游经济的空间分异特征及演化规律，探讨其内在影响因素.研究发现：1) 从全流域看，长江经济带各省市旅游经济的绝对差异逐年扩大，相对差异不断缩小，旅游经济的专业化程度缓慢提升；2) 从上中下游各区域看，长江经济带不同区域旅游经济的绝对差异和相对差异均呈不同程度的下降，上游地区较低的区域经济水平突显了旅游业在国民经济中的比较优势，中游各省市绝对差异和相对差异均最小且下降幅度最大，下游的相对差异最大.3) 区域经济发展水平、基础设施状况是影响长江经济带旅游经济时空分异的主要因素，对外开放程度对此亦有贡献.4) 长江经济带旅游经济已经形成了下游网络化、中游均质化、上游专业化的空间结构，并有望向更为平衡的方向发展.

Spatial and temporal differentiation of tourism economy in the Yangtze River Economic Belt and its influencing factors

The overall coordinated development of tourism industry in the Yangtze River Economic Belt is the key to the optimization of tourism spatial pattern in China. Using the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2001 to 2017， geospatial analysis and multiple regression analysis methods were used to study the spatial differentiation characteristics and evolution rules of tourism economy in the Yangtze River Economic Belt， and to explore its intrinsic factors. The study found as follows. 1) From the perspective of the whole basin， the absolute differences in the tourism economy of the provinces and cities in the Yangtze River Economic Belt have been expanding year by year， while the relative differences have been shrinking， and the specialization rate of the tourism economy has slowly increased. 2) The absolute and relative differences in tourism economy of the upper， middle and lower reaches have declined to varying degrees. The lowest regional economic level in the upper reaches of the region has highlighted the comparative advantage of tourism in the national economy. The absolute and relative differences in the provinces and cities in the middle reaches are the smallest and the largest， respectively. The relative difference in the downstream is the largest. 3)The level of regional economic development and infrastructure are the main factors affecting the spatial and temporal differentiation of tourism economy in the Yangtze River Economic Belt. The degree of openness also contributes to the scale of tourism economy. 4) The tourism economy of the Yangtze River Economic Belt has formed a spatial structure of networkization at downstream， homogeneity at midstream， and specialization at upstream， which is expected to develop in a more balanced direction.
