黄河沿线河南段节点城市的旅游经济空间结构研究

A Study on the Spatial Structure of Tourism Economy of Node Cities along the Yellow River in Henan Province

以修正的引力模型为基础,对黄河沿线河南段8个节点城市2010年、2014年、2018年的旅游经济联系强度进行测算,借用社会网络分析方法从网络密度、核心-边缘模型、中心度三个方面衡量黄河沿线河南段节点城市的旅游经济网络结构.研究发现:1)沿线节点城市的旅游经济联系量总体呈现上升的趋势,旅游经济联系越来越密切.2)沿线节点城市旅游经济网络密度呈现稳步上升趋势,区域合作意识不断加强.节点城市核心区与边缘区处于稳定状态,但旅游发展程度相差较大,旅游经济网络结构处于不均衡状态.3)沿线节点城市形成了以郑州市、洛阳市、开封市、焦作市为核心的旅游经济网络格局,随着开封市、新乡市、焦作市旅游经济的发展,沿线节点城市不均衡发展态势正在逐渐改善.根据研究结果,从加强区域合作、整合旅游资源、完善交通网络等角度提出建议,以便促进黄河沿线河南段节点城市旅游经济的协调发展.

Based on the modified gravity model,this paper calculates the intensity of tourism economic connection of eight node cities along the Yellow River in 2010,2014 and 2018,and measures the tourism economic network structure of node cities in Henan section along the Yellow River by social network analysis from three aspects:network density,core edge model and centrality.The results showed that:(1)The tourism economic connection of node cities along the line is on the rise,and the tourism economic ties are getting closer;(2)The density of tourism economic network of node cities along the line has been increasing steadily with the regional cooperation being strengthened.The core area and the edge area of the node cities are in a stable state,but the tourism development is quite different with the tourism economic network structure in an unbalanced state;(3)The node cities along the line have formed a tourism economic network with Zhengzhou,Luoyang,Kaifeng and Jiaozuo as the core.With the development of tourism economy in Kaifeng,Xinxiang and Jiaozuo,the unbalanced development of the node cities along the line is gradually improving.According to the research results,such suggestions as strengthening regional cooperation,integrating tourism resources and improving transportation network are put forward to promote the coordinated development of tourism economy in Henan node cities along the Yellow River.
