摘　　要：基于城市综合质量、双向时间距离等多角度构建引力模型,剖析合肥—南京双城都市圈经济联系时空格局,并运用社会网络分析法,探索城市经济网络的空间结构。研究发现:合肥—南京双城都市圈经济联系强度呈现双核引领、“东强西弱”“中部强南北弱”的格局;都市圈间互动性较弱,交集区域协同发展潜力巨大;合肥经济网络关联的正外部性未充分发挥。经济联系网络渐趋紧密,但程度不高、结构稳定性弱;都市圈总体上的资源辐射能力强于资源集聚能力;核心城市“一家独大”的局面有所弱化,区域经济联系不均衡性得到改善。凝聚子群地域邻近性强但城市构成不稳定,南京都市圈内部子群凝聚力较强。因此,要强化圈际衔接,打造一体化交通,建设科创共同体,携手共建产城融合。A gravity model was constructed based on the comprehensive city quality and the bidirectional time distance to analyze the spatial and temporal pattern of the economic relations between Hefei and Nanjing two cities.The spatial structure of the urban economic network was explored by social network analysis.The findings are as follows:The economic connection strength of Hefei–Nanjing metropolitan area is led by two cores,with a"strong east,weak west"and"strong central,weak north and south"pattern;The interaction among circles is weak,and the potential for coordinated development in the intersection area is huge;The positive externality of economic network connection in Hefei has not been fully developed.The economic network is getting more closely connected,but not to a high level,and the structural stability is weak;The resource radiation capacity of the metropolitan area is stronger than its resource agglomeration capacity on the whole;The situation of the core city being"dominant"has changed,and the imbalance of regional economic connections has been improved.The geographical proximity of the cohesive subgroups is strong,but the composition of the cities is unstable,and the cohesion of the subgroups within the Nanjing metropolitan area is relatively strong.Therefore,it is necessary to strengthen the inter-circle connection,create integrated transportation,build a scientific and technological innovation community,and jointly promote the city-industry integration.
