摘　　要：基于2010~2020年278个地级市面板数据,以中国政府2015年实施的绿色数据中心试点为准自然实验,应用双重机器学习模型,探究绿色数字基建影响不同种类绿色创新的内在机理与多维政策效应。研究发现:绿色数字基建切实激发了城市绿色创新,并表现出明显的实质性绿色创新偏好。机制检验表明:绿色数字基建能通过提升能源效率、抑制污染排放与吸引数字人才、鼓励数字创业来间接驱动绿色创新发展。进一步分析表明,绿色数字基建的绿色创新效果表现出“高质量发展区>非高质量发展区”“数字经济集聚区>非数字经济集聚区”“非资源型城市>资源型城市”的异质赋能特征。Based on the panel data of 278 prefecture-level cities from 2010 to 2020,this study takes the green data center pilot implemented by the Chinese government in 2015 as a quasi-natural experiment,applying the double machine learning model to explore the internal mechanisms and multi-dimensional policy effects of green digital infrastructure on different types of green innovation.The study finds that green digital infrastructure effectively stimulates urban green innovation and shows obvious substantive green innovation preferences.The mechanism test shows that green digital infrastructure can indirectly drive the development of green innovation by improving energy efficiency,curbing pollution emissions,attracting digital talents and encouraging digital entrepreneurship.Further analysis shows that the green innovation effect of green digital infrastructure shows the heterogeneous empowerment characteristics of high-quality development zones>non-high-quality development zones,digital economic agglomeration zones>non-digital economic agglomeration zones and non-resource-based cities>resource-based cities.
