区域经济多极网络空间组织识别方法及应用——以广东为例

Identification Method and Application of Spatial Organization of Regional Economic Multi-polar Network:A Case Study of Guangdong Province

基于多极网络空间组织的特征,从空间经济网络发育、多个增长极共存、增长极与空间经济网络的共生关系等方面,构建了多极网络空间组织识别方法。除借鉴已有的空间经济网络、增长极分析方法之外,建立了能综合反映增长极经济属性和关系属性的测度指标,并根据位序-规模法则筛选出备选增长极,从而构建了多增长极共存识别方法;通过引入生态学的共生思想和理论,首次分析了多增长极与空间经济网络的共生关系。运用这套方法,揭示了广东的多极网络空间组织现象。其一,广东空间经济网络的规模和连通度在持续增大,网络密度呈现先下降后上升的趋势,但整体发展水平与理想状态存在差距,且空间上偏集于珠三角。其二,已经形成了深圳、广州两个增长极共存的格局,而且,佛山和东莞有发展成为增长极的潜质。其三,增长极与空间经济网络之间形成了非对称互惠共生关系。这说明所建立的多极网络空间组织识别方法是有效的,可以为同类研究提供借鉴。

Based on the characteristics of Multi-polar network spatial organization,this paper constructs a multi-polar network spatial organization identification method from the aspects of the development of spatial economic network,the coexistence of multiple growth poles,and the symbiotic relationship between growth poles and spatial economic network.In addition to using the existing spatial economic network and growth pole analysis methods for reference,this paper establishes a measure index which can comprehensively reflect the economic attribute and relation attribute of the growth pole,and selects the alternative growth poles according to the Rank-Size Rule so as to construct a multi-growth pole coexistence identification method.And by introducing the symbiotic thought and theory of ecology,this paper analyzes the symbiotic relationship between multi-growth poles and spatial economic network for the first time.The paper also use this method to reveal the phenomenon of multi-polar network spatial organization in Guangdong province.First,the scale and connectivity of Guangdong spatial economic network continue to increase,and the network density shows a trend of first decline and then rise,but the overall development level is far from the ideal state,and it is spatially concentrated in the Pearl River Delta.Second,a pattern of coexistence of Shenzhen and Guangzhou growth pole has been formed,and Foshan and Dongguan have the potential to develop into growth poles.Third,there is an asymmetric and mutually beneficial symbiosis relationship between the growth pole and the spatial economic network.All these show that the method of establishing Multi-polar network spatial organization identification is effective and can be used as a reference for similar research.
