区域治理网络、联结机制与跨界合作结构——来自长三角城市群的实证分析

多主体参与、多功能类型和多层次耦合的区域治理网络已成为化解区域性公共问题、提升区域综合承载力的重要机制。借鉴社会网络理论和分析方法，通过对区域治理网络中多元主体间交互联结机制形成机理的研究，以及结合长三角的实证分析，探讨区域治理网络的整体结构、个体位置和跨界合作的结构逻辑。研究发现，长三角城市群区域内由政府、市场与社会共同参与的治理网络已初步形成，主体间关系发展呈现出一定程度的核心-边缘结构特征，区域中存在相互嵌套的凝聚子群，省域内部就近密集抱团与环环相扣的合作结构模式明显，核心城市成为跨界合作的重要枢纽。

Regional Governance Network,Network Linking Mechanism and Cross-boundary Cooperation Structure:Evidence from Yangtze River Delta Urban Agglomeration

Regional governance network which are multi-actors involved, multi-functions, and multi-levels interacted is becoming an important mechanism to resolve regional public issues and enhance the overall carrying capability. This research applies the social network analysis method, studies the formation mechanism of regional governance network linking relationships, presents an empirical research on governance networks of Yangtze River delta urban agglomeration, and investigates the overall structure, individual position, and cross-boundary cooperation structural logic of regional governance network. The result shows that the governance network with the participation of government, market, and society has emerged in the Yangtze River Delta. The development of actors' relations presents a certain degree of core-periphery structure characteristic. There are several nested cohesive subgroups in the region. The phenomenon of consociate inside Province and interlocking structure cooperation model is obvious, and the core cities have became an important hubs for cross-boundary cooperation.
