关中城市群旅游经济网络结构研究

Study on Tourism Economic Network Structure of Guanzhong Urban Agglomeration

以关中城市群11个城市为研究对象,选用2006年、2011年和2016年旅游经济数据,基于引力模型测算各城市间旅游经济联系度,借助社会网络分析法,全面分析关中城市群旅游经济网络结构特征及演变趋势,并对影响因素进行分析。研究发现:关中城市群各城市旅游经济联系总量不断增加但差异明显,西安市最高,商洛增幅最快;关中城市群呈现以西安为中心的旅游经济联系网络,网络结构不断完善,2016年整体网络密度达0.6182;旅游经济网络的核心—边缘结构明显,西安的核心地位不可取代,天水、平凉和庆阳不断被"边缘化";关中城市群呈现明显的四个等级结构,西安为核心旅游地;经济社会发展水平、旅游资源禀赋、交通可达程度等综合影响着关中城市群旅游经济空间相互作用强度和网络结构发育程度。

Taking the 11 cities of Guanzhong City Group as the research object this paper selects the tourism economic cross section data in 2006, 2011 and 2016, it calculates the tourist economic contact degree between cities based on the gravitational model, and it analyzes the characteristics and evolution trend of the tourism economic network structure in Guanzhong City Group by means of social network analysis. The influencing factors were analyzed. The study found that： the first, the tourist economic links in the cities of Guanzhong City Group are increasing, but the difference is obvious. The total amount of Xi＇an is the highest, and the tourism economic relation of Shangluo is the fastest increased; the second, the Guanzhong City Group presents the tourism economic contact network with Xi＇an as the center, and the network structure is continuously improved. The overall network density in 2016 is 0.6182; the third, the core-edge structure of the tourism economic network is obvious, the core status of Xi＇an cann＇t be replaced, Tianshui, Pingliang and Qingyang are constantly ＂marginalized＂; the fourth, the Guanzhong City Group presents four distinct hierarchical structures, Xi＇an is the core destination of tourism; the Fifth, the level of economic and social development, the tourism resources endowment, traffic accessibility etc. They have a comprehensive influence on the intensity and direction of the spatial interaction of tourism economy and the degree of development of network structure.
