摘要
农业生产导致的温室气体排放以及引发的环境问题,已成为人们关注的热点,研究物联网发展对农业碳排放强度的作用机理,有助于农业农村能源转型和促进农业绿色可持续发展。基于2010—2021年我国除港、澳、台外的31个省级地区的面板数据,分析物联网发展对农业碳排放强度的影响,以及科技创新在此过程中的作用。研究发现:物联网发展显著抑制了农业碳排放强度,并且存在显著异质性,在中国东部和中部地区,科技创新水平有效提升了物联网发展对农业碳排放强度的抑制作用。把农业科技创新水平作为门槛变量,发现物联网发展和农业碳排放强度之间存在非线性关系,当农业科技创新水平跨越门槛值后,物联网发展对农业碳排放强度的抑制作用显著增强。研究结论在推动数字化农业、促进科技与农业融合方面具有理论和实践价值。
Greenhouse gas emissions caused by agricultural production and environmental problems have become the focus of attention.Studying the mechanism of the development of the Internet of Things on agricultural carbon emission intensity will help agriculture and rural energy transformation and promote the green and sustainable development of agriculture.Based on the panel data of 31 provinces in China from 2010 to 2021,the impact of IoT development on agricultural carbon emission intensity and the role of scientific and technological innovation in this process were analyzed.The results show that the development of the Internet of Things significantly inhibits agricultural carbon emission intensity,and there is significant heterogeneity.In eastern and central China,the level of scientific and technological innovation effectively promotes the inhibition of the development of the Internet of Things on agricultural carbon emission intensity.Taking the level of agricultural science and technology innovation as the threshold variable,there is a nonlinear relationship between the development of the Internet of Things and agricultural carbon emission intensity.When the level of agricultural science and technology innovation crosses the threshold,the development of the Internet of things has a stronger inhibitory effect on agricultural carbon emission intensity.The research results provide theoretical and practical value for promoting digital agriculture and promoting the integration of science and technology with agriculture.
