【摘要】 本文通过构建包含创新集聚部门的新经济增长模型，理论阐释了创新集聚对工业绿色转型的非线性作用机制，并基于2006—2020年中国282个城市面板数据，实证检验了创新集聚对工业绿色转型的非线性影响及异质性、空间溢出效应，并验证财政纵向失衡和外商直接投资在其中的调节效应。研究发现：创新集聚对工业绿色转型影响呈U型特征；创新集聚在有效推动东部城市、一线城市工业绿色转型的同时，却抑制了中部城市、资源型城市、四五线城市工业绿色转型；创新集聚影响工业绿色转型的U型特征受到财政纵向失衡的负向调节和外商直接投资的正向调节；创新集聚对地理距离相近地区工业绿色转型的影响存在显著的倒U型空间溢出效应。更多还原

【Abstract】 By constructing a new economic growth model that includes innovation agglomeration sectors, the nonlinear mechanism of innovation agglomeration on industrial green transformation is theoretically explained. Furthermore, based on the panel data of 282 cities in China from 2006 to 2020, this paper empirically tests the nonlinear impact, heterogeneity and spatial spillover effects of innovation agglomeration on industrial green transformation, and verifies the moderating effect of fiscal vertical imbalance and foreign direct investment. The research finds that innovation agglomeration has a U-shaped impact on industrial green transformation, which is still true after a series of robustness tests; Innovation agglomeration can effectively promote the green transformation of industries in eastern cities and first tier cities, but it has suppressed the green transformation of industries in central cities, resource-based cities, and fourth and fifth tier cities; The U-shaped relationship between innovation agglomeration and industrial green transformation is negatively regulated by fiscal vertical imbalance and positively regulated by foreign direct investment; There is a significant inverted U-shaped spatial spillover effect of innovation agglomeration on the green transformation of industries in regions with similar geographical distances.更多还原
