中文摘要:基于新结构经济学理论,运用空间杜宾模型,依据长江经济带108个城市2003-2019年数据,考量产业集聚技术外部性发挥的有限性,以及政府科教支持对产业集聚技术外部性的交互作用。结果显示:在一定临界值之前,产业集聚能推动全要素生产率的提升,过度集聚则会产生拥塞效应,多元化集聚可能产生的拥塞效应更强,专业化集聚对全要素生产率的作用更稳定,产业集聚对全要素生产率具有积极的空间溢出效应。政府加大教育支持有助于释放产业集聚的技术外部性,但在当前的支持力度下,政府科教支持效果甚微。

The Impact of Industrial Agglomeration on Total Factor Productivity in the Context of Governmental Science and Education Suppont:A Case Study of 108 Cities Along Yangtze Economic Belt
Abstract:Based on the new structural economic theory, this paper estimates the limitation of the technological externalities of industrial agglomeration, and the interaction between the government’s scientific and educational support and industrial agglomeration by constructing Spatial Durbin Models and using the data of 108 cities in the Yangtze River Economic Belt from 2003 to 2019. The results show that below a certain critical value, industrial agglomeration can promote the improvement of total factor productivity, while excessive agglomeration will produce a congestion effect. The congestion effect of diversified agglomeration is stronger, and the effect of specialized agglomeration on TFP is more stable. Industrial agglomeration has a positive spatial spillover effect on TFP. The government’s increasing educational support helps to release the technological externalities of industrial agglomeration, but the government’s scientific support has little effect under the current level of support.
