摘　　要：文章以江苏省为研究区域,研究了江苏省城市竞争力、区域创新与生态效率的时空耦合关系。通过构建三者的综合评价指标体系,利用耦合模型、趋势面分析、引力模型等对2009-2018年三者间耦合协调度进行测算,并对其空间联系进行分析,在此基础上,探讨了其耦合关系的时空演变规律。结果表明:2009-2018年江苏省城市竞争力、区域创新与生态效率之间的动态关系处于较合适的状态;从城市的空间分布布局看,省内各个城市的耦合协调度表现为“南高北低、东高西低”的空间差异性;从空间联系量来看,三者之间的空间溢出效应明显,以常州、苏州和镇江为中心,各城市之间相互联系、相互影响,生态效率的改善和区域创新能力的提升对城市竞争力的提升有着重要影响。Taking Jiangsu province as the research area,this paper studies the spatial-temporal coupling relationship among urban competitiveness,regional innovation and ecological efficiency in Jiangsu province.By constructing the comprehensive evaluation index system of the three,this paper calculates the coupling coordination degree of the three from 2009 to 2018 by using the coupling model,trend surface analysis and gravity model,and analyzes their spatial relationship.On this basis,it discusses the spatiotemporal evolution law of the coupling relationship.The results show that the dynamic relationship among urban competitiveness,regional innovation and ecological efficiency in Jiangsu province from 2009 to 2018 is in a more appropriate state;from the perspective of urban spatial distribution,the coupling coordination degree of each city in the province shows the spatial difference of"high in the south and low in the north,high in the east and low in the west";in terms of spatial connection,the spatial spillover effect among the three cities is obvious,with Changzhou,Suzhou and Zhenjiang as the centers,and the cities are interconnected and influenced each other.The improvement of ecological efficiency and regional innovation ability has an important impact on the promotion of urban competitiveness.
