互联网依赖对家庭碳排放的影响--收入差距和消费升级的链式中介作用

The Impact of Internet Dependence on Household Carbon Emissions-The Chain Intermediary Role of Income Gap and Consumption Upgrade

以互联网依赖理论为基础,借助2016—2018年中国家庭追踪调查(CFPS)的微观数据库,采用STIRPAT模型和Bootstrap链式中介模型,实证分析互联网依赖对家庭消费碳排放的影响及链式中介传导机制。研究结果表明:互联网依赖对家庭碳排放存在显著正向影响;收入差距与消费升级在互联网依赖对家庭碳排放的正向影响中具有显著的直接中介作用。但是,收入差距和消费升级的链式中介作用具体表现为遮掩效应,即互联网依赖通过收入差距的缩小造成消费升级减缓,进而降低碳排放。在未来实现碳中和目标的过程中,政府应协调处理减排与收入差距和消费升级的关系,推进差异化减排策略,倡导低碳型消费模式。

This paper utilizes the STIRPAT model and the Bootstrap intermediary model to empirically analyze the impact of Internet dependence on household carbon emissions and the chain mediation mechanism,using the 2016—2018 China Family Tracking Survey(CFPS)micro-database.The results show that Internet dependence has a significant positive impact on household carbon emissions.The income disparity and consumption upgrades have a significant direct intermediary role on the positive impact of Internet dependence on household carbon emissions.However,the intermediary effect of the chain of income disparity and consumption upgrade is specifically manifested as a masking effect,that is,the Internet dependence slows down consumption upgrades through the reduction of income disparity,thereby reducing carbon emissions.The results show that in the process of achieving the goal of carbon neutrality in the future,the government should coordinate the relationship between emission reduction and income disparity and consumption upgrading,promote differentiated emission reduction strategy,and advocate low-carbon consumption mode.
