知识跨区域流动的隐形壁垒及其作用机制

The invisible barriers of knowledge cross-regional flow and its mechanism

构建以中国城市知识密集型产业授权发明专利大数据为核心的多源数据库,运用中介效应模型探究知识跨区域流动的隐形壁垒及其作用机制。研究发现:①中国城市知识存在跨区域流动现象且愈加显著,但流动网络呈现非均衡性空间特征,且较强的知识流动同时存在于邻近和远距离区域间;②在控制交通距离前提下,地方社会文化、制度和认知距离对知识跨区域流动产生显著负向影响,成为影响区域协同创新的隐形壁垒;③社会文化壁垒和制度壁垒通过影响区域间信任关系对知识跨区域流动产生显著的阻碍效应,而认知壁垒通过影响知识学习和吸收能力显著阻碍知识跨区域流动。研究结果为区域创新联动及其多重隐形壁垒的破除策略提供参考。

Under the background of information,capital,labor,commodities and other factors with super mobility,the space-time compression effect has largely weakened the geographical distance barrier of knowledge flow.At the same time,the embeddedness in the knowledge production and learning process highlights the important role of non-geographical factors such as local socio-cultural,institutional and cognitive level in the cross-regional flow of knowledge.This paper uses the big data of authorized invention patents of knowledgeintensive industries in Chinese cities and constructs the mediation effect model to explore the invisible barriers and their mechanisms of knowledge flow across regions.The findings are as follows:1)The cross-regional flow of knowledge in Chinese cities is increasingly significant,but the flow network is characterized by spatial imbalance,which conforms to the spatial differentiation of"Hu Line"on the whole.In addition,strong knowledge flows exist between adjacent cities and distant cities at the same time.This shows that local contexts such as social culture,institution and cognition have more and more significant impacts on knowledge flow,and knowledge flows across regions are characterized by the coexistence of proximity and distance in the era of the knowledge economy.2)Under the premise of controlling traffic distance,local socio-cultural,institutions,and cognitive distance have a significant negative impact on knowledge flow across regions,becoming invisible barriers to regional collaborative innovation.3)Socio-cultural and institutional barriers significantly block knowledge flow by influencing the intermediary path of the trust relationship between regions.Cognitive barriers significantly hinder knowledge flow across regions by influencing the intermediary path of regional learning and absorptive capacity.The research results provide references for regional innovation linkage and strategies for breaking down multiple invisible barriers and promoting regional high-quality integrated development.The academic contribution of this paper is that we introduce the trust-learning mechanism,deeply explain the mechanism of invisible barriers such as socio-cultural,institution and cognition that hinder the knowledge flow across regions,and deepen the understanding of the regional innovation school on knowledge dynamics in the process of economic development.
