摘要
在全球低碳发展与数字经济深度融合的背景下,城市的绿色低碳转型路径成为学术界关注的焦点。信息技术作为城市发展的关键支撑,信息消费的崛起为城市绿色低碳转型提供了新路径。以国家信息消费城市试点政策(ICPC)为准自然实验,基于2013—2023年我国城市的面板数据,采用双重差分法系统检验ICPC对城市二氧化碳和二氧化硫排放的作用效应。研究结果显示,ICPC显著抑制了城市二氧化碳和二氧化硫的排放,且在行政等级较高的城市政策效应更趋显著,不同区域与消费类型城市间未呈现异质性差异。机制分析表明,ICPC通过刺激政府研发支出、推动数字技术应用与赋能企业绿色创新三条作用渠道,助力城市绿色低碳发展。研究为准确评估ICPC的环境外部性、丰富城市绿色低碳转型的理论框架提供了经验支撑。
Urban green and low-carbon development is the focus of academic attention under the current background of deep integration of the digital economy,while information technology is a key component of urban development.To boost information consumption,China introduced the Information Consumption Pilot City(ICPC)policy in 2016.However,the impact and mechanisms of the ICPC on urban green and low-carbon development remain unclear.This study uses panel data from Chinese cities(2013 to 2023)and a difference-in-differences approach to examine the ICPC policy's effects on urban CO_(2)and SO_(2)emissions.The results show that the ICPC significantly reduces urban CO_(2)and SO_(2)emissions,with a more pronounced effect in cities with higher political rankings.No significant differences were found across regions or consumption-type cities.Mechanism analysis indicates that the ICPC promotes low-carbon urban development by increasing government R&D spending,encouraging digital technology adoption,and driving corporate green innovation.This study offers theoretical insights for evaluating the externalities of the ICPC and advancing urban green and low-carbon development.
