大湄公河次区域城市群空间经济联系分析

Spatial Economic Relationship of Cities Group in Great Mekong Subregion

以大湄公河次区域(GMS)47个城市为研究对象,运用社会网络分析和Multilevel p2模型方法,分析GMS城市群空间经济联系结构、程度及影响因素。结果表明,目前GMS城市群空间经济联系呈"核心-边缘"分布的三级圈层结构,各层级之间经济发展差异较大,空间经济联系程度比较松散。同时,GMS城市群空间经济联系程度还受单个城市经济、资源集聚效应的影响,而城市间要素的扩散效应影响尚不显著。随着各成员国经济发展速度加快,GMS城市群空间经济网络正迅速形成与拓展,中心城市的增加与城市之间相互建立新的经济联系将显著增强该次区域空间经济关联度,未来强化产业支撑、拓展通道建设、完善合作机制是加深GMS城市空间经济联系的发展方向。

The paper analyzed the economic relations and spatial structures in cities group of Great Mekong Subregion( GMS) by using the social network analysis and Multilevel p2 model methods. The analysis results about the economic network among GMS cities can be stated as follows. The economic structures of GMS cities are three layers which are meeting the theory of core-edge. The economic development of the cities from different layers are quite different and the degrees of economic networks are loose. The intensity of GMS spatial economic relationship is affected by a city power of gathering economy and resources. However,the diffusion effect capacity among cities is not yet significant to the degree of GMS spatial economic network. With the rapid developing of GMS member states' economies,the establishment of new mutual economic ties will significantly enhance the relevance of GMS spatial economic relationships. Based on the results above,further development direction of the spatial economic linkages on GMS cities is to strengthen cooperation in industrial,infrastructure and institutional.
