摘　　要：数字化是新质生产力的重要支撑,以其生态化属性赋能城市发展,进而塑造城市创新格局。基于宽度、高度和重叠度的三维生态位理论,构建城市数字化影响创新空间演变的分析框架,并使用2011—2021年284个城市面板数据开展实证检验。研究发现:城市数字化激发了城市创新活力,尤其是良好的数字生态提高后发城市的创新吸收能力,从而缩小后发城市与先发城市间的创新差距,使我国创新空间演化呈现条件β收敛特征;数字化对创新空间演变的影响取决于城市所处的数字生态位,其中生态位宽度和高度的提升能够提高后发城市的创新吸收能力;生态位的适度重叠有利于促进城市间科创资源共享和价值共创,且该作用受到城市间认知邻近性的调节;不同城市在数字化赋能过程中分化为领跑型、赶超型、中等型、发展型、落后型5种类型,对不同类型城市存在差异化的数字发展策略。研究发现为激发城市数字化发展新动能、促进城市协同创新提供了新思路。Digitalization is an important support for new quality productivity,and empowers urban development with its ecological attributes,which in turn shapes the innovation space.Based on the three-dimensional ecological niche theory,it constructed an analytical framework to analyze the impact of urban digitalization on evolution of innovation space,and used the panel data of 284 cities from 2011 to 2021 to conduct empirical tests.The results show that urban digitalization stimulates the urban innovation vitality,and enhances the innovation absorption capacity of developing cities by improving digital ecosystem,which narrowes the innovation gap between developing cities and developed cities,and makes the evolution of innovation space in China show conditionalβ-convergence characteristics.The impact of urban digitalization on the evolution of innovation space dependes on the digital ecological niche.The improvement of digital ecological niche width and height enhances the innovation absorptive capacity.The moderate overlap of digital ecological niches promotes the sharing of innovation resources and value co-creation between cities,and this effect is moderated by the cognitive proximity between cities.In the process of digital empowerment,different cities are divided into five types,and there are different digital development strategies for different types of cities.The findings provide new ideas for stimulating new momentum of digital development and promoting urban collaborative innovation.
