摘　　要：基于中国19大城市群的数字技术专利数据,采用多中心性测度方法分析2011-2020年城市群数字技术生产结构与关系结构多中心性,并使用非线性检验、调节效应、与工具变量模型检验城市群多中心性对新质生产力的非线性影响与调节效应.研究发现:中国城市群数字技术生产格局与关系格局均经历了“集中→分散→集中”的演化过程;城市群数字技术多中心性结构与新质生产力呈现显著的“倒U型”关系;人力资本是数字技术知识多中心结构影响城市群新质生产力的有效调节路径;空间单元异质性影响城市群数字技术多中心性的作用效果.建议警惕城市群数字技术结构过度平均化,注重区域发展差异和完善数字技术创新网络布局以优化中国城市群数字技术空间布局.Based on the digital technology patent data of 19 major urban agglomerations in China,this study uses a multi centrality measurement method to analyze the multi centrality of digital technology production structure and relationship structure in urban agglomerations from 2011 to 2020.Nonlinear tests,moderation effects,and instrumental variable models are used to test the nonlinear and moderation effects of urban agglomerations'multi centrality on new quality productivity.Research has found that the production pattern and relationship pattern of digital technology in Chinese urban agglomerations have undergone an evolutionary process of"concentration-dispersion-concentration";The polycentric structure of digital technology in urban agglomerations exhibits a significant"inverted U-shaped"relationship with new quality productivity;Human capital is an effective regulatory path for the multi center structure of digital technology knowledge to affect the new quality productivity of urban agglomerations;The heterogeneity of spatial units affects the effectiveness of digital technology polycentricity in urban agglomerations.It is recommended to be vigilant against the excessive homogenization of digital technology structure in urban agglomerations,pay attention to regional development differences,and improve the layout of digital technology innovation networks to optimize the spatial layout of digital technology in Chinese urban agglomerations.
