摘　　要：数字基础设施是新兴技术研发及其推广应用的重要前提,对新质生产力发展的影响效应和作用机制亟待探讨。本文通过构建综合指标体系并运用熵权-TOPSIS方法测度了我国城市层面新质生产力发展水平,以“宽带中国”试点城市政策为准自然实验,基于2007-2021年地级市面板数据并使用渐进双重差分模型探讨了数字基础设施建设对于城市新质生产力发展的影响。基准回归结果表明数字基础设施建设能够显著提升城市新质生产力发展水平,且通过一系列稳健性检验。机制检验结果表明,数字基础设施建设主要通过新质劳动力、新质劳动资料、新质劳动对象三大要素推动城市新质生产力发展。异质性分析结果表明,数字基础设施建设将对不同区域、不同规模、不同个体特征的城市新质生产力发展产生差异化影响。我国应加快推进数字基础设施建设,充分发挥城市数字基础设施建设对劳动力数量稳步增长和质量提升的双重带动效应,推动信息技术与传统产业深度统合,积极培育新兴产业和未来产业,因地制宜发展新质生产力。Digital infrastructure is an important prerequisite for the research and development of emerging technologies and their popularization and application, and the effect and mechanism of its influence on the development of new quality productivity need to be explored urgently. This paper measures the development level of new productivity at the city level in China by constructing a comprehensive index system and applying the entropy weight-TOPSIS method, and explores the impact of digital infrastructure construction on the development of new productivity at the city level based on the panel data of prefectural-level cities in the period of 2007-2021 by using the asymptotic double-difference model, which is based on the policy of pilot cities of Broadband China as a quasi-natural experiment. The results of the benchmark regression show that digital infrastructure development can significantly increase the level of urban new quality productivity development and pass a series of robustness tests. The results of mechanism test show that digital infrastructure construction mainly promotes the development of urban new quality productivity through three major factors: new quality labor force, new quality labor materials, and new quality labor objects. Heterogeneity analysis shows that the “Broadband China” pilot policy will have a differentiated impact on the development of urban new quality productivity in different regions, sizes, and individual characteristics. China should accelerate the construction of digital infrastructure, give full play to the double driving effect of digital infrastructure construction on the steady growth of the quantity and quality improvement of the labor force, promote the in-depth integration of information technology and traditional industries, and actively cultivate new and future industries on the basis of the deep enhancement of the total factor productivity of traditional industries, so as to develop the new quality productivity according to the local conditions.
