中文摘要：

基于权重结构视角,刻画我国产学研合作网络关系分布及结构演化。研究发现,产学研合作网络关系分布不均衡,网络主体间合作质量偏低。产学研合作趋于强关系异配网络演化,强关系主体合作广度差异性降低而深度异质性逐渐增强,网络＂富人俱乐部＂现象逐渐减弱。在我国＂关系＂社会背景下,长期以来,由于缺乏市场调节机制没有形成良好的协同创新环境,导致大量网络主体机会主义、搭便车的短期合作行为,合作难以摆脱单向而缺乏深度交互的困境,技术创新系统中技术知识传递不对称,网络协同创新效应难以形成。因此,网络主体应充分重视网络关系管理,政府部门应优化设计市场机制,引导网络关系分布调控合作中的市场失灵。

英文摘要：

Based on the perspective of network weighted structure, this paper study network ties distribution and structure evolution of University-Industry Collaboration. The result shows that is seriously unbalanced for network ties distribution and the large number of actors＇ collaboration is low quality. The evolution of collaboration network tend to heterogeneous networks in China, in the process of evolution, the strong tie actor＇ cooperative breadth differences decreased, cooperative depth increased, and network ＇rich club＇ increasingly weakened. For a long time, in China＇s guanxi context, due to the lack of market regulation mechanism, it is difficult to form a good synergy innovation environment. Lead to a large number of network acts＇ short term collaborative behavior of＇ opportunism＇ and ＇free riding＇. It is difficult for actors to get rid of the dilemma of one-way and lack of depth interaction, that technical knowledge transfer asymmetry in innovation system, which is difficult to for actors form network synergy innovation effect. Therefore, network actors should pay more attention to network ties management, the government departments should design and optimize the market mechanism, then guidance network ties distribution to manage market failure of University-Industry collaboration.
