摘要
产业空间联系是区域经济联系的核心内容,对促进城市群一体化发展具有重要意义。本文通过投入产出模型中的感应度系数和影响力系数,构建长江中游城市群产业联系强度测度模型,并结合社会网络方法分析产业空间联系方向、分异特征及网络结构。研究结果表明:(1)产业联系强度以京九、京广、沪昆铁路为主要发展轴向两侧降低,主要联系方向具有中心和地域邻近指向性;(2)从空间分布形态来看,主要以武汉、长沙、南昌为核心点向四周降低,产业对外联系总量较低的区域基本分布在3个核心省会城市构成的三角区域周边,呈现核心—边缘特征,同时部分地区形成“洼地”和低值集中区;(3)从网络格局来看,主要以少数大城市为核心建立复杂产业联系网络,且发育不均衡;南昌、武汉、长沙、岳阳、宜春、常德等城市在网络中发挥重要的中介作用。
Industrial spatial association is the core of regional economic association,which is of great significance to regional economic integration of urban agglomeration.This article proposes a measurement model for the industrial association intensity by introducing the inductance coefficient and influence coefficient in the input-output model,and then analyzes the industrial spatial connection direction,differentiation characteristics,and network structure.Our results show that:(1)the industrial association intensity becomes weak from Beijing-Kowloon,Beijing-Guangzhou and Shanghai-Kunming railway lines to their two sides,and the main association direction has central directivity and geographical proximity;(2)the spatial structure of industrial association is reduced to the periphery with Wuhan,Changsha and Nanchang as the core points,and the regions with low external contact basically distributed around the triangle area composed of these three core capital cities,showing the overall core-edge feature and meanwhile“depressions”and low-value concentration features for some regions;and(3)in terms of the industrial association network,a complex industrial association network has been established with a few large cities as the cores,such as Nanchang,Wuhan,Changsha,Yueyang,Yichun,Changde and other cities,playing an important intermediary role in the network,though the network is not well developed.
