摘　　要：为揭示PPP项目中社会资本合作关系的形成与发展逻辑,基于我国2003—2022年交通运输PPP项目数据,运用社会网络分析方法探究社会资本合作网络的结构与特征,并结合交易成本理论和网络嵌入理论,从社会关系网络的视角,考察情感性关系网络和认知性关系网络对社会资本合作网络的影响机制。结果表明:随着我国PPP模式的不断发展,社会资本合作网络逐渐由小宗派网络演变成为半开放型网络,网络密度不断增大,网络凝聚性不断增强,整体网络呈现出多中心、扁平化的关系结构;情感性关系运作是社会资本合作网络得以形成的基本逻辑,认知性关系运作是社会资本合作网络进一步扩张的补充逻辑。This research aims to reveal the logic of the formation and development of social capital partnerships in PPP projects.Based on the data of transportation PPP projects from 2003 to 2022 in China,the structure and evolution characteristics of social capital cooperation network are explored using social network analysis theory.Then,the emotional and cognitive relationship networks are examined from the perspective of social relationship networks by combining transaction cost theory and relationship embedding theory.The results show that:(1)with the continuous development of PPP model in China,the social capital cooperation network gradually evolves from a small sectarian network to a semi-open network,with increasing network density andcohesion,and the overall network presents a polycentric and flattened relationship structure;(2)in the process of network evolution,the operation of affective relationships is the basic logic of social capital cooperation network formation,and the operation of cognitive relationships is the complementary logic for the expansion of social capital cooperation network.
