Technology transfer, knowledge spillover and industrial green transformation from the perspective of externalities
利用专利交易数据和社会网络分析，研究了技术转移对产业绿色转型的促进作用，发现其通过集聚经济、能源效率和绿色技术创新产生空间溢出效应，且在大城市效果更显著。
Applying social network analysis and constructing a spatial econometric model using patent transaction data, we analysed the effect of technology transfer on industrial green transformation. Evidently, technology transfer promotes industrial green transformation (and this finding remains valid after endogeneity and robustness tests), the agglomeration economy, energy-use efficiency and green technology innovation. We also identified a spatial spillover effect that further promotes industrial green transformation. Finally, technology transfer has a heterogeneous effect on industrial green transformation across regions: big cities improve green technological innovation and production efficiency by accumulating more innovation resources and forming closer innovation linkages.
