摘　　要：城市群的协同发展对于我国经济资源的空间优化配置和国家重要战略的落实意义重大。然而,目前政策主导下的城市群建设模式违背了城市群协同发展的经济规律。本文在集聚—扩散这一城市群协同发展基本经济规律的基础上,以长三角城市群为研究对象,构建相关指标来统计分析城市群的空间形态以及产业空间布局和分工变化的特征事实,客观考察长三角城市群协同发展机制的演变历程。研究发现:(1)城市群规模层级体系和经济网络特征分析显示,随着中小城市经济的快速发展,长三角城市群规模层级体系的等级性在降低,空间形态已呈现出多中心网络化特征以及都市圈层特征,核心城市上海的辐射能力有所减弱,龙头作用有待加强。部分都市圈之间竞争大于合作,都市圈融合发展有待深入。(2)制造业和生产性服务业空间分布特征的变化显示,长三角城市群各都市圈内部虽然已经形成了显著的产业分工模式,中心城市在生产性服务业上具有规模优势和专业化优势,中小城市在制造业上具备专业化优势,但是中心城市之间,以及周边中小城市之间存在显著的产业同构。在以上研究基础上,本文进一步提出促进长三角城市群协同发展的政策建议。The coordinated development of urban agglomeration is very important for the spacial optimal allocation of economic resources and the implementation of national strategies.However,the construction of urban agglomeration dominated by government policies violates the economic law of coordinated development of urban agglomeration.Based on the law of agglomeration-diffusion and taking the Yangtze River Delta urban agglomeration as the research object,this paper constructs relevant indicators and statistically analyzes characteristic facts of the urban agglomeration’s spatial form and industrial distribution and division,which objectively reflects the evolution process of the coordinated development mechanism of Yangtze River Delta urban agglomeration.This research finds that:(1)The analysis of characteristics of urban agglomeration’s hierarchy system and economic network shows that with the rapid economic development of small and medium-sized cities,although hierarchy system of urban agglomerations in the Yangtze River Delta is decreasing and the spatial form has the characteristics of multi-center networking and metropolitan circles,the radiation capacity of the core city--Shanghai has weakened and its leading role needs to be strengthened.Meanwhile,the relationship among some metropolitan areas is over-competitive rather than cooperative,which implies that the integrated development of metropolitan areas needs to be deepened.(2)The changes of manufacturing and productive services sector’s spatial distribution characteristics show that each metropolitan area has formed reasonable industrial division mode,the central cities specializing in producer services and the small and medium-sized cities specializing in manufacturing.However,the assimilation of industrial structure is still very serious among the central cities and their surrounding small and medium-sized cities.Finally,based on the above research results,this paper puts forward policy suggestions to promote the coordinated development of urban agglomera
