摘要
基于复合系统协同度模型,将城市群解析为由经济、社会、生态等子系统集成的复合系统,以长株潭城市群为对象,探讨国家“两型”社会综合配套改革试验区获批成立以来长株潭城市群经济-社会-生态协同发展水平的演化特征并探寻其提升路径。结果表明:1)从城市群尺度看,2007—2019年长株潭城市群经济、社会、生态子系统有序度总体呈提升趋势,复合系统协同度由轻度失调走向中度协同;2)从城市尺度看,长沙市、株洲市已实现中度协同,湘潭市仍为轻度协同,研究期内长沙市复合系统协同度持续强化、株洲市与湘潭市相对弱化;3)长株潭城市群协同发展目前存在两大问题,一方面城市群总体协同水平偏低、社会-生态子系统变化缓慢,主要制约序参量为基础设施和环境治理;另一方面城市间协同水平存在明显差距,主要制约序参量为经济规模、发展质量、产业结构和污染排放;4)长株潭城市群协同发展水平的进一步提升,在城市群尺度下需合理制定各子系统有序发展与协同目标,健全城市群财政及公共事务统筹管理机制;在城市尺度下各城市应补足短板、提升发展能级,不断完善城市间互动合作机制。
Promoting the coordinated development of urban agglomerations is a fundamental goal in new urbanization construction in China.It is an inherent requirement for condensing the joint efforts of various cities,and a primary path to maximizing the overall benefits and enhancing the competitiveness of urban agglomerations.Based on the composite system synergy degree model,this study analyzes urban agglomeration as a composite system integrated with the economy,society,and ecology subsystems.Using evidence from the Changsha-Zhuzhou-Xiangtan urban agglomeration,we research the evolutionary characteristics of its coordinated development level since the resource-saving and environment-friendly development experimental area was established.We also explore the improvement path of optimizing the coordinated development of urban agglomerations.The results show that from 2007 to 2019:1)at the urban agglomeration scale,the order degree of economy,society,and ecology subsystems in the Changsha-Zhuzhou-Xiangtan urban agglomeration displays an overall improvement trend,and the synergy degree of the composite system changed from mild imbalance to moderate synergy;2)at the urban scale,Changsha and Zhuzhou have achieved moderate synergy,while Xiangtan remains at mild synergy;the synergy degree of the composite system in Changsha continues to strengthen,and those in Zhuzhou and Xiangtan are relatively weakened;3)the two main problems in the coordinated development are that the coordinated level is low,and the socio-ecological subsystem changes slowly with the main infrastructure and environmental governance constraints.In addition,there are obvious gaps in the level of coordination between cities,with constraints in the economic scale,development quality,industrial structure,and pollution emissions;and 4)to further improve the level of coordinated development of the Changsha-Zhuzhou-Xiangtan urban agglomeration,it is necessary to reasonably formulate the orderly development and coordinate the goals of various subsystems at the scale o
