摘　　要：作为推进数字经济战略和高质量发展的重大举措,数智基建被广泛认为能够创造巨大的经济价值,但数智基建能否以及如何创造绿色价值仍有待深入论证。文章以“宽带中国”试点城市为准自然实验,基于2011—2020年280个地级市及以上城市面板数据展开实证分析,检验数智基建是否促进了城市绿色价值创造,并探讨数智基建如何创造绿色价值。结果表明:数智基建能显著提高城市绿色价值创造,这一结论在一系列稳健性检验后仍然成立。机制分析发现,该影响是通过集聚效应和创新效应实现的,其中集聚效应包括人才集聚和产业集聚,创新效应包括促进绿色技术创新和提高城市创新创业活跃度。进一步分析发现,数智基建的绿色价值创造效应在营商环境好、行政级别高及科教资源较好的城市更明显。文章研究结论为数智基建促进城市绿色高质量发展提供了政策启示。As a major initiative to promote the strategy of digital economy and high-quality development,digital infrastructure is widely recognized as capable of creating great economic value,but whether and how digital infrastructure can create green value remains to be demonstrated in depth.In this paper,we conduct an empirical analysis based on 280 city-level panel data from 2011 to 2020 in a quasi-natural experiment in the pilot cities of Broadband China to examine whether digital infrastructure promotes green value creation in cities,and to further explore how digital infrastructure creates green value.The results show that Digital Intelligence Infrastructure significantly enhances urban green value creation,a finding that still holds after a series of robustness tests.Mechanism analysis reveals that the impact is realized through agglomeration effects and innovation effects,where agglomeration effects include talent concentration and industry clustering,and innovation effects include promoting green technological innovation and increasing urban innovation and entrepreneurship activity.Further analysis reveals that the green value creation effect of digital intelligence infrastructure is more obvious in cities with good business environment,high administrative level and better scientific and educational resources.The findings of this paper provide policy insights for the promotion of urban green development by digital intelligence infrastructure.
