创新资源、门槛效应与城市增长

Innovation Resources, Threshold Effects and Urban Growth

摘要:

通过分析创新资源对城市增长的关系,为优化创新资源投入,促进城市增长提供参考。选取了长三角地区26个城市2006-2015年的面板数据,使用固定效应模型来检测创新资源及其控制变量与城市增长之间的作用关系。为进一步说明,以创新资源作为门槛变量,研究了二者之间的非线性关系。研究结果显示：创新资源对城市增长的影响存在显著的三门槛效应。因此,应该合理地投入创新资源,使其最大程度的促进城市的增长。

Abstract:

By analyzing the relationship between innovation resources and urban growth, we can provide references for optimizing investment in innovation resources and promoting urban growth. The panel data of 26 cities in the Yangtze River Delta region from 2006 to 2015 were selected and fixed effect models were used to detect the relationship between innovation resources and their control variables and urban growth. To further illustrate, using innovation resources as a threshold variable, we study the nonlinear relationship between the two. The research results show that there are significant three threshold effects of innovation resources on urban growth. Therefore, we should rationally invest in innovation resources so that it can maximize urban growth.
