摘　　要：数字经济发展为释放人力资本红利、激发城市创新潜能提供了新契机。本文以“宽带中国”试点政策为准自然实验,使用多时点双重差分方法考察数字经济发展的人力资本红利释放效应和城市创新促进效应,并分析有为政府与数字经济的协同作用。研究发现,整体上数字经济发展能够提高城市创新产出,且该促进作用在东部地区、一线城市和市场潜能较大的地区更为明显。机制分析表明,数字经济通过促进劳动力流动、优化人力资本结构和缓解人力资本配置扭曲来提高城市创新水平。考虑异质性处理效应、改变创新测度方式和排除其他政策干扰的稳健性检验都支持主要结论。进一步分析表明,有为政府增强了数字经济对城市创新产出的促进作用,且强化了数字经济对人力资本的增量补充、结构优化和效率提升机制。本文为进一步释放数字红利、优化创新资源空间配置、提升城市创新潜能以挖掘持续经济增长动力提供了新的分析视角和理论依据。Innovation is the engine of economic growth and the fundamental driving force for high-quality economic development.However,China faces challenges in its current R&D and innovation landscape,including insufficient allocation of innovation resources,a low level of basic scientific and technological innovation,and weak industrialization of innovations.These issues underscore the structural barriers to “transforming from a factor-driven to an innovation-driven development model”,highlighting the urgent need to reshape China's innovation system and build an innovation-driven country.Human capital is the cornerstone of innovation and can be further leveraged through the development of a digital economy,which has the potential to stimulate innovation.In view of this,this paper examines the effects of digital economic development on human capital dividends and urban innovation,using city-level panel data from 2003 to 2020 and quasi-natural experiments based on the Broadband China Pilot Policy.Employing a multi-period double-difference approach,the study further analyzes the synergistic effects of effective government and the digital economy and finds that the development of the digital economy can improve urban innovation output,mainly by promoting labor mobility,optimizing the human capital structure and alleviating human capital allocation distortion.Further analysis shows that effective government enhances the effect of the digital economy on facilitating urban innovation output,and strengthens the incremental supplementation,structural optimization,and efficiency enhancement mechanism of digital economy on human capital.Heterogeneity analysis reveals that the innovation-promoting effect of the digital economy is more pronounced in eastern areas,first-tier cities,and areas with greater market potential.The marginal contributions of this paper are as follows.First,from the perspective of incremental human capital supplementation,structural optimization,and allocation efficiency enhancement,this paper constructs a
