摘要
针对2000—2015年间各地级以上城市经济联系强度的格局演变,以长江三角洲城市群26个地级以上城市为研究对象,采用城市流强度修正城市吸引力规模参数的城际空间联系强度模型,分别从城市群内部经济联系测度和时空格局变化两个方面对长三角城市群经济发展联系度进行横向和纵向对比分析。研究结果表明,2000—2015年间长三角城市群城市流强度和经济联系度均持续上升,空间结构已明显表现出多个都市圈绵延发展态势,符合各城市经济在外向功能量和功能效率的变化趋势,可为推动区域经济协调发展提供理论参考。
Standing on intensity of economic interaction pattern evolution of cities above prefecture level in 2000—2015,26 cities in Yangtze River Delta urban agglomeration are studied.The model of urban flow intensity is used to correct the city attraction scale parameters.The revised inter-city economic contact strength model is adopted.From the two perspectives of spatial measurement and pattern change of the economic connection within the urban agglomeration,the horizontal and vertical comparative analysis of the economic development of the urban agglomeration is carried out.The research shows that,the urban flow intensity and economic connection degree of the urban agglomeration in Yangtze River Delta all show a continuous upward trend during 2000—2015.From the perspective of spatial distribution,the economic structure of urban agglomerations in Yangtze River Delta has shown a clear trend of metropolitan expansion.This is basically consistent with the changing trend of urban economy in outward function and function efficiency,which could promote a theoretical reference for coordinated development of regional economy.
