摘要
城市间频密的经济联系是城市群的重要特征,并随城市群发育程度的提升而增强。本文以我国发育程度最高的城市群之一--珠三角城市群为实证案例,基于改进的引力模型法、地理信息系统(Geographic Information System,GIS)和二次指派程序(Quadratic Assignment Procedure,QAP)分析法,结合社会经济数据,对2000~2019年城市间经济联系的演变特征进行了分析,并探讨了影响因素。研究发现:珠三角城市群经济联系强度不断提升,其中广州与其余各城市间的经济联系增量最多,深圳市的增幅最大;珠三角城市群经济联系方向呈现稳中有变的趋势,且各个城市的相对地位因此不断发生变化。经济距离差异、经济发展与城镇人口增长、产业分工与产业联系、政策推动是影响经济联系变化的主要原因。其中,经济距离差异是基本原因,与经济联系总量高度负相关;经济发展快慢与城镇人口增速是直接原因,与经济联系的增强保持同步性;产业发展与产业分工则是间接因素,与经济联系的变化具有正相关性;政策因素则是重要推手,在影响经济联系方面发挥着重要作用。本文研究有助于厘清近20年珠三角城市群经济联系的演变特征及影响因素,对制定促进城市群高质量发展的规划与政策具有一定启示意义。
Economic link is an important form of interaction among cities,especially in urban agglomeration areas,and it is increasing with the development level of urban agglomerations.The present study takes the Pearl River Delta urban agglomeration as an empirical case,based on the improved gravity model method,GIS spatial analysis and QAP analysis,combines with social and economic data,analyzes the evolution characteristics of urban economic links in 2000~2019,and discusses the influencing factors.The main results are as follows:While the economic links of the Pearl River Delta urban agglomeration kept increasing constantly,Guangzhou has the largest increase in economic links with other cities,and Shenzhen has the largest increase;the direction of economic links variations in stability,and the relative position of cities in economic links are changing.Economic distance difference,economic development and urban population growth,industrial division and industrial links,and policy promotion are the main influencing factors of economic links.Among them,the difference in economic distance is the basic factor,and highly negatively correlated with the total amount of economic links;the speed of economic development and the urban population growth rate are the direct factors,and its growth is synchronized with the strengthening of economic links;industrial division and industrial links of labor are indirect factors,which have a positive correlation with changes in economic links;policy factors are important promoters and play an important role in influencing economic links.This study can help to clarify the evolution characteristics and influencing factors of the economic links in the Pearl River Delta urban agglomeration,and may have a certain reference for optimizing the urban links and promoting the improvement of urbanization quality.
