摘　　要：“宽带中国”试点是加强数字基础设施建设,以数字化推动企业绿色创新发展的重要途径。将“宽带中国”试点政策作为一项准自然实验,选取2011-2021年2 037家A股上市公司样本数据,运用多时点双重差分模型检验“宽带中国”试点政策对企业绿色创新的影响。研究发现:①“宽带中国”试点政策能够显著促进企业绿色创新,经过平行趋势检验、PSM-DID检验等一系列稳健性检验后结论依然成立;②“宽带中国”试点政策对企业绿色创新的影响具有所有权、行业和城市环境规制水平异质性,试点政策对国有企业、重污染行业以及低环境规制城市企业的促进作用更显著;③机制检验表明,“宽带中国”试点政策主要通过提高城市数字金融水平和推动企业数字化转型两条路径促进企业绿色创新,具体表现为提高城市数字金融使用深度和覆盖广度以及增强企业数字化转型关注度和资源投入,与企业数字化转型相比,城市数字金融所发挥的中介效应更显著;④进一步分析表明,“宽带中国”试点政策溢出效应明显,具体表现为上市公司总部对子公司绿色创新以及对邻近城市企业绿色创新的空间溢出效应。研究结论有助于丰富企业绿色创新影响因素研究,并为全面理解“宽带中国”试点政策赋能机理以及新一代信息基础设施建设提供参考。Green development is the fundamental way to implement the concept of a community with a shared future for mankind and achieve the goals of"carbon peak"and"carbon neutrality".Furthermore,green innovation is a powerful driving force for green and high-quality development,and enterprises are an important subject of green innovation.Therefore,in order to continuously promote green development of economy and society and achieve the"dual carbon"goal,it is particularly important to explore new paths for green innovation in enterprises.At the same time,the government attaches great importance to the coordination of green and digital development in its economy and society.Emerging digital technologies represented by the Internet,5G technology and big data have been playing a key role in enabling innovation and driving high-quality economic development.In this context,the"Broadband China"pilot policy was proposed in 2013 and committed to building a well-connected network across China.As a result,the construction and application level of network infrastructure have significantly improved,which is beneficial for enterprises to obtain technical information and strengthen technical connections between enterprises.Then,how will the"Broadband China"pilot policy,by enhancing the level of network infrastructure construction,impact green innovation for enterprises?The answer to this question not only helps to uncover the mechanism behind the pilot policies empowering green innovation in enterprises but also provides relevant policy recommendations for the new generation of information infrastructure construction,thereby helping to achieve the"doble carbon"goal.Drawing on the green development background and resource-based theory,this paper takes the pilot policy of"Broadband China"as a quasi-natural experiment to test its impact and mechanism on green innovation.The empirical test is made based on the data of 2037 A-share listed companies from 2011 to 2021 and the DID model.The results indicate that,firstly,enterprise green innovat
