The Impact of Interregional Collaboration on Multistage R&D Productivity and Their Interregional Gaps in Chinese Provinces

Abstract

Interregional collaboration is a core element of Chinese innovation policy, as it accelerates the knowledge recombination across geographic boundaries and promotes regional R&D performance. This study emphasizes interregional collaboration and investigates its effect on R&D productivity using 2009–2017 panel data for 30 Chinese provinces. Furthermore, it examines the relationship between interregional research collaboration and interregional gaps of R&D productivity based on a multistage perspective. Our findings reveal that although interregional collaboration and R&D productivity in China constantly improved during the study period, there is to some extent a mismatch in their spatial distribution. We find that interregional collaboration is required to support overall R&D productivity. We also emphasize that interregional collaboration contributes more to narrowing the interregional gaps of knowledge productivity (rather than technology transfer productivity).
