以“智慧城市”政策试点作为数字新基建引入标志，实证检验其对数字技术创新的政策赋能效应、机制路径与经济后果。研究结果显示，智慧城市建设能够显著提升试点城市的数字技术创新水平。机制检验表明，智慧城市试点通过提升政府数字关注度、强化财政科技扶持、吸引高层次人才聚集，促进数字技术创新。拓展分析发现，智慧城市政策通过提升数字技术创新，进一步推动新质生产力跃升、缩小城市经济差距、提升绿色全要素生产率。为此，应深化智慧城市试点推广，持续激发数字技术创新活力，以数字技术创新为支点撬动城市经济高质量发展。

Using the “smart city” policy pilot as the introduction marker of digital new infrastructure, this study empirically tested its policy empowerment effect, underlying mechanisms, and economic implications for digital technology innovation.The findings indicate that smart city construction significantly increased the level of digital technology innovation in pilot cities.Mechanism testing demonstrated that the smart city pilot boosted digital technology innovation by enhancing government attention to digital initiatives, strengthening fiscal support for science and technology, and attracting high-caliber talent.Further analysis revealed that by promoting digital technology innovation, the smart city policy advanced the evolution of new quality productive forces, reduced economic disparities between cities, and enhanced green total factor productivity.Consequently, it is recommended to deepen the promotion of smart city pilot programs, continually stimulate momentum for digital technology innovation, and leverage such innovation as a fulcrum for driving high-quality urban economic development.
