摘　　要：数字时代的到来,为经济增长与生态环境协调发展提供了新动能和新契机。该研究运用2011—2020年中国省级面板数据,在构建经济增长与生态环境协调发展综合指标体系的基础上,运用固定效应模型、空间杜宾模型及门限回归模型,多维度实证考察数字化对二者协调发展的影响及其内在机理。研究结果表明:①考察期内,经济增长与生态环境耦合协调度时间上呈平稳上升态势,空间上呈现东高、中西低的格局。②数字化能够有效推动经济增长与生态环境协调发展,在考虑了一系列稳健性检验后该结论依旧成立。就内在机制而言,产业转型升级、创新水平提升和能源效率增强在数字化赋能过程中发挥了重要传导作用。③分区域检验表明,数字化对经济增长与生态环境协调发展的影响存在区域异质性,相较于西部,数字化对东、中部地区的赋能效应更为显著,且该作用在东北地区并不显著。④从空间维度来看,数字化对经济增长与生态环境协调发展具有显著空间溢出效应,即数字化有助于提高邻近地区经济增长与生态环境协调发展水平。⑤门限检验表明,在人力资本水平和数字基础设施约束下,数字化对经济与环境协调发展的推动作用表现为非线性影响,在通过固定的门槛值后该影响会发生改变,具有显著的门槛特征。基于此,该研究从夯实数字基建,加快数字技术在生态领域的应用;深化产业结构调整,推动研发水平提升,助力能源效率增强;结合区域发展特点,制定差异化发展策略等方面提出政策建议。The advent of the digital age has provided new momentum and opportunities for the coordinated development of economic growth and the ecological environment.Based on the panel data from Chinese provinces from 2011 to 2020 and the construction of a comprehensive index system for the coordinated development of economic growth and ecological environment,this study examined multiple dimensions using the fixed effects model,the spatial Durbin model,and the threshold regression model to empirically investigate the impact of digitization on their coordinated development and its underlying mechanisms.The research findings indicated that:①During the observation period,the coupling coordination degree between economic growth and the ecological environment showed a steady upward trend over time,with a spatial distribution pattern that was high in the eastern region and low in the central and western regions.②Digitization effectively promoted the coordinated development of economic growth and the ecological environment,and this conclusion still held after a series of robustness tests.In terms of the underlying mechanisms,industrial transformation and upgrading,improvement of innovation levels,and enhancement of energy efficiency played significant mediating roles in the process of digitization empowerment.③Regional analysis revealed heterogeneity in the impact of digitization on the coordinated development of economic growth and the ecological environment.Compared to the western region,digitization had a more significant empowering effect in the eastern and central regions,while its impact was not significant in the northeast region.④From a spatial perspective,digitization exhibited a significant spatial spillover effect on the coordinated development of economic growth and the ecological environment,meaning that digitization contributed to improving economic growth and ecological environment coordination in neighboring regions.⑤Threshold analysis demonstrated that the impact of digitization on the coordinated devel
