农业信息化如何影响碳生产率

How Agricultural Informatization Affects Carbon Productivity

作为新质生产力的重要支撑,信息通信技术有助力于“双碳”目标实现,但其效应受到城乡数字鸿沟制约。基于2000—2018年县域面板数据,以“农业农村信息化示范省”为政策冲击,使用渐进双重差分方法,研究农业信息化对碳生产率的影响及作用机制。结果表明:农业信息化对碳生产率具有显著且稳健的提升效应,而城乡技术进步深化与要素配置优化是农业信息化提升碳生产率的重要机制。此外,人力资本水平越高、财政自主权越强及市场一体化程度越高,农业信息化的碳生产率提升效应则越明显。

As a vital support for new quality productive forces,information and communication technology can contribute to the achievement of the“dual carbon”(carbon peak and carbon neutrality)targets,but its effect is constrained by the urban-rural digital divide.Regarding“agricultural and rural informatization pilot provinces”as the shocks,using county-level panel data from 2000 to 2018 and time-varying difference-in-differences method,this paper reveals the impact and mechanism of agricultural informatization on carbon productivity.It shows that agricultural informatization has a robust improvement effect on carbon productivity.Urban-rural technological progress and factor allocation optimizing are important mechanisms for these effects.In addition,the higher the level of human capital,the stronger the fiscal autonomy,and the greater the degree of market integration,the more pronounced the effect of agricultural informatization on carbon productivity improvement becomes.
