长江经济带入境旅游经济时空格局动态性——基于ESDA&GWR法

以5 a为时间间隔，运用ESDA法采用旅游外汇收入平均增长量和平均增长率指标，研究长江经济带126个市域单元2000~2015年入境旅游经济的空间格局演化特征，运用GWR法分析入境旅游经济影响因素的空间异质性。结果表明：（1）长江经济带旅游外汇收入平均增长量莫兰指数经历了 0.164 6~0.164 1~0.057 2的变化趋势，增量相似市域由较强集聚向较弱集聚转化，市域旅游经济增长趋于均衡。一级热点区始终位于江浙沿海市域。一级冷点区由研究区中部向苏北转移，空间范围大大缩小。（2）长江经济带旅游外汇收入平均增长率莫兰指数表现为 0.098 6~0.293 1~0.198 9 的变化趋势，市域之间旅游经济增长关联程度增强，总体差异逐渐缩小。一级冷热点区大幅度转移，同时热点区范围大幅度扩大。后期热点市域数量大大超过冷点市域数量。（3）入境旅游发展较为落后的湖南省、云南省增长速度最快，长三角城市群所属市域始终是入境旅游经济增长最活跃的地区。

A STUDY ON SPATIAL-TEMPORAL PATTERNS OF REGIONAL DEVELOPMENT DISPARITIES IN YANGTZE RIVER ECONOMIC ZONE

The spatial-temporal quantitative analysis of the economic,environment,social andregional development level of 130 cities in the Yangtze River Economic Zone in 2003,2008 and 2013 by means of the comprehensive evaluation model.Studying on spatial-temporal distribution pattern of regional development difference of the Yangtze Economic Zone by exploratory spatial data analysis and hot and cold point analysis.The results showed:spatial pattern of economic development level in Yangtze River economic zone was downstream area higher than midstream area higher than upstream area,economic development gap of Inter-regional first increased and then narrowed.Spatial pattern of social construction level in Yangtze River economic zone was downstream area higher than midstream area higher than upstream area.Spatial pattern of environmental protection level in Yangtze River economic zone was upstream area higher than midstream area higher than downstream area,environmental protection gap of Inter-regional gradually narrowed.Spatial pattern of regional development level in Yangtze River economic zone was downstream area higher than midstream area higher than upstream area,regional development gap of Inter-regional first increased and then narrowed.Regional development level of high value areas and hot spot areas gathered in the downstream areas,showing the tendency expand to the midstream area;the low-value agglomeration areas and cold spot areas were gathered in the upstream area,showing the tendency contraction to the upstream area.Finally,according to the above-mentioned conclusions,we put forward some corresponding policy recommendations.
