摘要
双核型城市群是我国城市群构建发展中一种特殊的地理现象。借鉴协同理论和增长极理论,构建双核型城市群复合系统,采用复合系统协同度模型,运用2011—2017年面板数据,以我国东部4个双核型城市群为案例,测度各城市群中心城市子系统有序度、港口城市子系统有序度和复合系统协同度,为此类城市群协同发展理论和实践提供一定依据。结果表明:1)4个双核型城市群复合系统协同度皆呈现增长趋势,在统计期末进入良好的协同发展状态,并表现出"高低低高"的特点;2)中心城市子系统和港口城市子系统有序度表现出同步增长态势;3)各中心城市子系统经历了一个无序发展到有序协同的历程,有序度不断提升,但有序度增长表现出明显的南北差异,2011—2017年北方中心城市有序度提升势头整体优于南方中心城市;4)各港口城市子系统有序度的提高在统计期期末呈现出比较明显的"高低低高"态势,总体状况不及中心城市子系统。
Dual-core city cluster is a special geographic feature during China’s city cluster development.This paper uses synergy theory and growth polarity theory to establish a dual-core city cluster compound system,applies compound system synergy model and 2011-2017 panel data to measure the order of central city sub-system,order of port city sub-system and synergy of compound system of eastern China’s four dual-core city clusters,providing references for theory and practice of such city cluster coordinated development.Results show their synergy displays a rising trend,entering an excellent coordinated developing stage,marked by high-low-low high.Orders of central city sub-system and coastal city sub-system are rising at same pace.Central city sub-system has experienced disorder to a rising order synergy,varying in the south and north that northern central city generally prevails the south during 2011 to 2017.Orders of port city sub-system do not show a conspicuous high-low-low-high trend,below the central city sub-system.
