摘　　要：城市群和都市圈已成为城市(镇)化的重要空间形态,也是区域经济发展的重要载体。在区域一体化以及城市网络建构和强化的背景下,城市群和都市圈已成为经济循环和竞争的重要空间单元。本研究结合都市圈一体化共生网络理论框架,探讨了都市圈一体化内部网络的特征与效应。研究发现:①共生节点和共生网络均具有层次性,且在中心城市与外围区域存在层级的分异,类型的转变和层级的攀升较为困难。②合肥都市圈一体化共生网络发育程度偏低,中心城市和外围地区在一体化中获益程度不同,呈现出由中心向外围地区递减的格局。③共生集聚和共生外溢效应共存于都市圈一体化共生网络。中心城市的集聚效应显著,在空间上广泛虹吸周边资源;共生外溢效应具有方向性,沿都市圈一体化重点发展轴线方向溢出。本研究从共生网络的视角,贴合都市圈一体化“合作、共生与多赢”的理念,提出了区域一体化以及城市网络研究的新思路,以期为高质量发展战略下的城市群与都市圈发展效益的提升与均衡化提供参考。Urban agglomerations and metropolitan areas have become important spatial forms of urbanization and important carriers of regional economic development.In the context of regional integration and the construction and strengthening of urban networks,urban agglomerations and metropolitan areas have become spatial units of economic circulation and competition.This study combines the theoretical framework of metropolitan area integrated symbiotic network to explore the characteristics and effects of the internal network of metropolitan areas.The study shows that:(1)Both symbiotic nodes and networks have hierarchy,and there is a hierarchical differentiation between the central city and peripheral areas.Agglomeration nodes mainly appear in central cities,while in peripheral cities,there are two types:agglomeration and spillover.The districts and counties under the jurisdiction of the central city are mostly middle to high-level nodes,while low-level symbiotic nodes are mostly distributed in the peripheral areas of the metropolitan area.And the transformation of symbiotic node types and the ascent of levels are relatively difficult.(2)The development level of the integrated symbiotic network in the Hefei metropolitan area is relatively low,but it has hierarchical characteristics,namely the existence of three levels:core network,associated network,and peripheral network.The profit of these three levels of symbiotic networks gradually weaken in the integrated symbiotic network,and show a decreasing pattern from the center to the peripheral areas.(3)Symbiotic agglomeration and symbiotic spillover effects coexist in the integrated symbiotic network of metropolitan areas.The agglomeration effect of central cities is significant,widely siphoning surrounding resources in space.However,the symbiotic spillover effect has directionality,overflowing along the key development axis of metropolitan area integration.Although the symbiotic agglomeration effect is still dominant in central urban areas at present,there is a trend of the s
