摘要
基于2001和2011年的数据,采用社会网络分析方法实证分析了丝绸之路经济带城市群经济联系网络的空间结构及其发展变化,结果表明:丝绸之路经济带城市群经济联系网络整体密度提高较快,2011年网络密度较高,但还有较大提升空间。网络中各城市对外经济联系强度差异较大,重庆、成都、昆明和西安等中心城市的辐射带动作用较明显,网络经济联系程度有集中的趋势。网络中存在4个凝聚子群和核心—边缘结构,凝聚子群内部和核心区域内经济联系比较紧密,但凝聚子群间、核心与边缘区域城市间的经济联系较弱,经济联系有待加强。
Based on the data of 2001 and 2011, an empirical analysis is made on the network of the economic ties of city groups along the Silk Road Belt about their spacial structure and the development. The results show that in general the network density of the city group economic ties develops fast, with the highest density in 2011. However, there is more room for improvement. The strength of economic ties for different cities to connect with the outside varies a lot. Cities like Chongqing, Chengdu, Kunming and Xi＇an are playing significant radiation and leading roles, and the degree of network economic tie tends to concentrate. There are four cohesive subgroups and the core - peripheral structures. The internal economic connections of the cohesive subgroups and the core regions are strong, but the economic connections among the cohesive groups and between the core cities and peripheral regions are weak. Therefore, the economic connections need to be strengthened.
