共生模式下的区域多中心合作——以北部湾经济区为例

Regional polycentric cooperation in the context of symbiosis model: the case of Guangxi Beibu Gulf Economic Zone

结合种群生态学的共生理论和区域一体化的多中心发展趋势,提出了区域多中心共生的概念,并以广西北部湾经济区为例,通过城市经济能级指数和共生密度等指标分析了经济区多中心共生与辐射的状况及机制,进而依据共生集聚与辐射关系提出了由"一个区域主中心、三个区域副中心以及两个集中区"构成的广西北部湾经济区"132"空间战略结构和网络运作模式。

Combining the symbiosis theory of population ecology and the perspective of polycentric regional integration, this essay proposes a regional polycentric symbiotic research framework, and takes the Guangxi Beibu Gulf Economic Zone as a case to study. Through the positive analysis of urban economic ability index and function field radius, it finds out the regional polycentric symbiosis and radiation situation and its mechanism. Basing on these outcomes and the relationship between symbiotic agglomeration and radiation, it puts forward a development mod- el including one regional main center, three regional sub - cen- ters and two concentrative areas, namely the ＂ 132 ＂ spatial structure and network operation model for Guangxi Beibu Gulf E- conomic Zone upgrade.
