文档名：数字经济发展如何影响碳生产率
摘要：数字经济发展逐渐成为实现双碳目标的重要途径.基于2011—2020年省级面板数据,建立指标评价体系对数字经济发展水平和碳生产率进行测度,运用中介效用模型、空间面板模型、门槛模型揭示数字经济发展对碳生产率的影响.研究发现:(1)数字经济发展对碳生产率有显著促进作用且存在区域异质性;(2)研发强度和环境规制在数字经济对碳生产率的传导机制中具有明显的中介作用;(3)数字经济促进碳生产率提高的同时也存在空间溢出效应;(4)数字经济对碳生产率的正向促进作用因消费结构水平的不同而存在门槛效应,两者间的关系会随着消费结构水平高低变动而发生变化.研究结论可为精准评估数字经济的减排效应、加速释放数字经济时代的碳生产潜力、统筹制定差异化的数字赋能绿色低碳转型战略提供经验证据和政策启示.
