近年来,新型基础设施建设("新基建")在国家战略层面密集部署,成为培育新兴产业和构筑新兴产业链的重要支撑.鉴于现有研究对城市空间尺度"新基建"影响新兴产业链不同环节发展效应的时空分异关注有限,该文分析2011-2022年中国主要城市"新基建"和人工智能产业链发展的时空特征,揭示城市"新基建"影响人工智能产业链上中下游不同环节发展效应的时空分异特征.研究发现:①2011年以来中国主要城市新型基础设施和人工智能产业链取得快速发展,在国家中心城市和城市群核心城市形成空间集聚;②城市"新基建"综合发展水平有效推动了人工智能产业链的发展,影响程度由高到低依次是下游应用层、中游技术层和上游基础层,推动效应随时间推移而强化;③城市"新基建"影响人工智能产业链发展的效应在空间上主要凸显于东部沿海地区和核心城市群,影响程度在城市群发展梯队之间的空间异质性超过东中西部三大地带之间的空间异质性,第一梯队城市群正成为城市"新基建"赋能人工智能产业链发展的重要空间载体.
Spatio-temporal Heterogenous of Influences of New-Type Infrastructure Construction on Artificial Intelligence Industry Chain Development for Cities in China
Recently,new-type infrastructure construction has been intensively deployed as national strategies to underpin the cul-tivation of emerging industry chain development.Given the inadequacies in understanding of spatiotemporal heterogenous influ-ences of new-type infrastructure construction on emerging industry chain development at the city-level,this paper seeks to por-tray the spatiotemporal development characteristics of new-type infrastructure construction and artificial intelligence industry chain development in major cities of China from 2011 to 2022,and to reveal the spatiotemporal heterogeneous influences of new-type infrastructure construction on artificial intelligence industry chain development.It is found as follows.① Since 2011,the new-type infrastructure construction and artificial intelligence industry chain of major cities in China have achieved rapid devel-opment,forming spatial agglomeration in nationally central cities and core cities of high-level urban agglomerations.② It is em-pirically verified that new-type infrastructure construction effectively facilitates the development of artificial intelligence industry chain in cities of China,with the most powerful promotion effects at the downstream activities,followed by the midstream and upstream activities,and the promotion effect is strengthened over time.③ The promotion effects of new-type infrastructure con-struction on artificial intelligence industry chain development of cities in China are highly agglomerated in the eastern coastal ar-eas as well as national-level core urban agglomerations.The degree of spatial heterogeneity across urban agglomerations with different development stages exceeds that across Eastern,Central,and Western regions.It is highlighted that the first-tier urban agglomerations in China are functioning as the key spatial carriers for new-type infrastructure to empower artificial intelligence industry chain development at city-level.
