Abstract
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.
期刊介绍：
Growth and Change is a broadly based forum for scholarly research on all aspects of urban and regional development and policy-making. Interdisciplinary in scope, the journal publishes both empirical and theoretical contributions from economics, geography, public finance, urban and regional planning, agricultural economics, public policy, and related fields. These include full-length research articles, Perspectives (contemporary assessments and views on significant issues in urban and regional development) as well as critical book reviews.
