以2005、2010和2015年为时间截面,基于修正引力模型和社会网络理论,借助Ucinet6.0软件分析了东北地区城市间旅游经济联系网络结构的演化特征,并提出东北地区旅游经济的发展模式及对策建议。结果表明：①东北地区城市间旅游经济联系表现出明显的阶段性特征,控制城市间旅游经济联系的主要通道集中于少数节点城市并在空间上产生迁移,旅游经济联系网络发展趋于均衡。②网络中存在明显的核心区与边缘区,旅游经济联系呈组团模式发展,组团格局经历了“弱联系稳定”、“强联系失衡”、“强联系相对稳定”三个阶段。③东北地区旅游经济应以“增长极—轴线—组团”模式实现进一步发展。
Based on the modified gravity model and social network theory and using the Ucinet6.0 software, this article analyzes the evolution characteristics of the network structure of urban tourism economic connections in Northeast China in the three periods of 2005, 2010 and 2015, and puts forward the spatial development patterns and strategies of tourism economy in Northeast China. The results showed that: (1)The tourism economic connections between cities in Northeast China are more and more closely linked, the radiation and spillover effects of the core nodes are constantly enhanced, but there is an obvious stage effect: In 2005-2010, the tourism economic connections between cities have increased rapidly from mononuclear structure to a multi growth polar radiation model; In 2010-2015, the connections have a slight decrease and partial adjustment, turning to the node-axis development pattern. The main channels to control the economic connections between cities are concentrated in a handful of cities and migrated in space, and the development of the tourism economic connection network tends to be balanced.(2)There are obvious core and periphery areas in the network, and the scope of the core area is constantly expanding, and the density of the internal network in the core area is increasing. The tourism economic connections in Northeast China has been developing in a group pattern. The group structure has experienced three stages: weak and stable connection, strong and imbalance connection, and strong and relatively stable connection. (3)The tourism economy in Northeast China should be further developed with the "pole-axis-group" pattern.
