本文探讨了不同类型的技术接近对创新增长的区际溢出效应的影响。利用包含2002-2019年中国省级专利和R&D投入的面板数据集，利用基于链接和基于结构的技术邻近度构建的空间权重矩阵，估计了知识生产函数。我们发现，两种类型的技术接近程度显著不同，对区域间创新溢出的贡献也不同。基于结构的邻近对溢出的影响较小，其在区域间创新溢出过程中的作用受区域发展水平的影响。本文旨在厘清技术接近的两个概念，比较它们对创新溢出的影响，并探讨它们之间的区域差异。
This paper explores the roles of different types of technological proximity on the interregional spillovers of innovation growth. Using a panel dataset containing Chinese province patents and R&D inputs from 2002 to 2019, this paper estimates a knowledge production function with the spatial weight matrices constructed based on the linkage‐based and structure‐based technological proximity. We find that the two types of technological proximity are significantly different and their contributions to interregional innovation spillovers differ. The structure‐based proximity shows a lower influence on spillovers and its effect in the process of interregional innovation spillovers is affected by the regional development level. This paper originates to clarify two conceptualizations of technological proximity, compare their influences on innovation spillovers, and explore their regional differences.
