Green Innovation Effects of Financial Factors Agglomeration:Spatial Correlation Characteristics and Heterogeneity of City Clusters
Building a regional green technological innovation system is an important foundation for the green transformation of the economy,while the spatial agglomeration of financial factors serves as an important accelerator for scientific and technological innovation activities.In the existing literature,the two main lines of financial factors agglomeration and green technological innovation have been discussed in detail and also considered the green innovation effect that endogenously leads to financial factors agglomeration,but few have systematically examined the spatial correlation effect of the two and their regional heterogeneity based on the characteristics of city clusters that are the new spatial supports for the regional synergistic development of the new period.Therefore,ten representative city clusters in China are selected to diagnose the spatial and temporal development trajectories and the spatial correlation heterogeneity of the agglomeration of financial factors and green technological innovation within city clusters.It concludes that:First,the agglomeration of financial factors through various spatial effects can help accelerate the development of green finance within city clusters and then positively promote the improvement of regional green technological innovation.Second,the agglomeration of financial factors within city clusters leads not only to obvious local support effects on regional green technological innovations,but also to significant spatial spillover effects.Third,the spatial effects of financial factors agglomeration on green technological innovations are also influenced by the spatial and temporal development of city clusters and the spatial and temporal heterogeneity of green technological innovations.Last,the spatial effect of agglomeration of financial factors on green technological innovation is also constrained by the financial agglomeration pattern of city clusters,administrative level characteristics,economic development status and other factors.On the basis,differentiated financial factors agglomeration patterns should be constructed around the development positioning of city clusters in the process of regionally coordinated development,so as to create green financial service systems and green technological innovation systems that meet the actual constraints of various urban clusters.At the same time,the spatial routing effects of financial factors agglomeration on green financial development and green technological innovation as well as their heterogeneous characteristics should be investigated,and the effective spatial interactions between financial reforms and green development should be promoted.And the spatial spillover effects of financial factors agglomeration on green financial development and green technological innovation as well as their heterogeneous characteristics are studied in depth to promote effective spatial interaction between financial reform and green economy.
