The contrasting effects of interregional networks and local agglomeration on R&D productivity in Chinese provinces: Insights from an empirical spatial Durbin model
本文利用2009-2017年中国30个省份的面板数据，通过两阶段研发过程模型，对比分析了省际合作网络与本地集聚对研发生产率的不同影响，发现网络提升研究效率，而集聚更促进技术转化。
This paper examines the contrasting effects of local agglomeration in innovation activities and the interregional networks derived from innovation collaboration on R&D productivity. Based on a two-stage R&D process, this study enriches the existing research and highlights the significance of interregional networks and local agglomeration in understanding spillover effects and productivity improvement. This study employs the network slacks-based measure model to quantify the R&D productivity of two successive stages of research and technology transfer using panel data from 2009 to 2017 for 30 Chinese provinces. It employs the spatial Durbin model to explore and compare the effects of interregional networks and local agglomeration on R&D productivity at each stage. The findings show that interregional networks play an important role in improving research productivity, while local agglomeration is more important in technology transfer research. The significant spatial spillover effect of technology transfer productivity in adjacent provinces indicates a large likelihood of convergences in R&D productivity. The results confirm that interregional networks and local agglomeration operate at distinct parts of the R&D process.
