摘要
采用中国2000—2019年城市面板数据,建立空间杜宾模型考察市场潜能对城市绿色创新效率的影响,并对其作用机制和空间溢出进行深入探讨。研究发现:(1)市场潜能显著提升了城市绿色创新效率,稳健性检验同样支持这一结论。(2)分析了市场潜能提升城市绿色创新效率的作用机制,并运用中介效应模型识别出了市场潜能可以通过经济集聚、市场竞争和产业结构升级等机制来促进城市绿色创新效率提升。(3)市场潜能对城市绿色创新效率的影响存在明显的区域差异性,提升作用呈现“东部—中部—西部”递减态势。(4)市场潜能对城市绿色创新效率的提升作用存在空间溢出效应,城市间距离在650公里以内为空间溢出效应的显著有效区域,超过950公里后则出现明显的衰减。为进一步提升城市绿色创新效率,从深化制度改革、强化作用机制和突破市场潜能衰减边界进行“空间重塑”等方面提出了政策建议。
Based on the urban panel data of China cities from 2000 to 2019,this paper establishes a spatial Durbin model to investigate the impact of market potential on urban green innovation efficiency,and discusses its mechanism and spatial spillover attenuation characteristics.The main results are as follows:(1)The market potential significantly improves the efficiency of urban green innovation,and the robustness test also supports this conclusion;(2)The paper analyzes the mechanism of market potential to improve the efficiency of urban green innovation,and uses the intermediary effect model to identify that the market potential can promote the efficiency of urban green innovation through the mechanisms of economic agglomeration,market competition and industrial structure upgrading;(3)There are obvious regional differences in the impact of market potential on urban green innovation efficiency,and the promotion effect shows a decreasing trend of“east-central-west”;(4)There is a spatial spillover effect of market potential on the efficiency of urban green innovation.The distance between cities within 650 km is a significant effective area of spatial spillover effect,and there is an obvious attenuation when it is more than 950 km.In order to further improve the efficiency of urban green innovation,this paper puts forward some policy suggestions from the aspects of deepening institutional reform,strengthening the function mechanism and breaking through the decline boundary of market potential to“reshape space”.
