淮海经济区国内旅游经济差异的时空分析

Spatial-temporal Analysis of Economic Disparity of Domestic Tourism in Huaihai Economic Zone

区域旅游发展差异是旅游经济学的重要研究内容之一。以淮海经济区各地级市2004—2014年国内旅游收入为数据基础,运用地理集中指数、泰尔指数、基尼系数、变异系数、联系强度和GIS相关空间分析方法探讨了淮海经济区国内旅游经济发展区域差异的演变特征。结果显示:1淮海经济区旅游经济差异总体上呈现出"先扩大后缩小"的阶段性特征,苏北、皖北、鲁南与豫东四大地区之间差异一直占据主要地位;苏北和鲁南地区的地区内部差异在逐步缩小,皖北与豫东在逐渐扩大。2淮海经济区国内旅游发展水平较高的地区主要集中在济宁、徐州、泰安和临沂四市形成的环形区域,皖北与豫东发展水平一直都处于较低水平,其他地区较为中等,在空间格局上呈现出"一圈一点一带一片"的特点。3淮海经济区两两城市间的联系强度表现出很大的差异,两极分化明显,东北地区的旅游联系强度远远超过西南地区。

Regional tourism development difference became one of the important research contents of tourism economics. Taking the domestic tourism revenue from 2004 to 2014 in the Huaihai Economic Zone as the basic data, employing geographic concentration index, Theil index, Gini coef- ficient, coefficient of variation, contact strength and the GIS spatial analysis method, this paper analyzed the evolution characteristics of regional differ- ence in Huaihai Economic Zone＇s domestic tourism economic development. The results showed that：（1）The tourism economic disparity in Huaihai Eco- nomic Zone enlarged first and then narrowed on the whole. The differences between the four regions of North Jiangsu, North Anhui, South Shandong and East Henan played a major role. The difference within the region in North Jiangsu and South Shandong was becoming smaller and smaller, while south Shandong and east Henan gradually expanding. （2）The domestic tourism areas in Huaihai Economic Zone with the higher level of development mainly include JiNing, Xuzhou, Taian and Linyi as the core, the development level in north Anhui and East Henan was on a low, other regions in me- dium. On the spatial pattern that showed＂One Circle, One Pole, One Belt, One Area＂. （3） As for the association strength, the pairwise city of Huaihai Economic Zone had a great difference which presented a polarization phenomenon, and the northeast regions＇ tourism association strength was much higher than the southwest regions.
