基于新经济地理“3D”框架的旅游经济空间结构特征分析——以长江三角洲地区为例

本文借鉴新经济地理学的"3D"(density,distance,division)框架理论,构建了旅游经济空间"T—3D"分析体系,分别以旅游经济地理集中度、时空距离及旅游联系诠释了旅游经济空间的密度、距离及整合。以长三角地区为例,刻画了旅游经济空间的T—3D特征。研究结果表明:长三角地区各市旅游经济空间密度的数值差异明显,空间分布差异显著,整体呈现"南疏北密"的分布特征;长三角地区旅游经济空间距离总体较优,各城市间距离较近,且差异不大,呈现出"核心—边缘"特征;旅游经济空间整合表现为上海、杭州、苏州三足鼎立之势,呈现出"一核两翼"的区域旅游发展特征。通过对长三角地区的实证分析,验证了旅游经济空间"T—3D"分析体系的有效性。

ANALYSIS OF SPATIAL STRUCTURE CHARACTERISTICS OF TOURISM ECONOMY BASED ON NEW ECONOMIC GEOGRAPHY “3D” FRAMEWORK: A CASE STUDY ON YANGTZE RIVER DELTA

Based on the "3D" framework theory of new economic geography and combining with the reality of tourism economy, this paper proposes a "T-3D" system of tourism space economy and builds a "T-3D" measurement model of tourism economy space. Described and analysed the T-3D feature of the tourism economic spatial in Yangtze River Delta region using the analysis softwares like ArcGIS, SPSS and so on. The T-3D system interprets the tourism economic space density, distance and division with tourism economic geographic concentration, time distance and contact strength. The density of the new economic geography is measured by the density of multipurpose land usually. Based on the relevant measurement index, this paper uses the geographic concentration of tourism economy to measure the spatial density of tourism economy. The results show that:The spatial distribution of tourism economy in the cities in the Yangtze River Delta is obviously different in spatial distribution, with significant differences in spatial distribution, showing the distribution characteristics of "Southern sparse and densely distributed"; the spatial distribution of tourism economy in the Yangtze River Delta is generally superior; near, with little difference, presenting the characteristics of "core-periphery"; the spatial integration of tourism economy shows the three pillars in Shanghai, Hangzhou and Suzhou, showing the characteristics of regional tourism development with "one core and two wings".
