数字农业建设对农业碳排放的影响

The impact of digital agriculture construction on agricultural carbon emission

【目的】探究数字农业建设对农业碳排放的影响,挖掘减排潜力,促进低碳农业发展。【方法】基于2013—2021年中国30个省、自治区、直辖市的面板数据,利用固定效应模型分析数字农业建设对农业碳排放强度的影响,并进行作用机制检验,探究其减排机制。【结果】数字农业建设对农业碳排放强度具有显著抑制作用。数字农业建设对农业碳排放的影响存在显著的异质性,对东、西部地区减排效应显著,中部地区则不显著。数字农业建设通过农业人力资本间接影响其对农业碳排放强度的抑制作用,而农业技术创新在数字农业建设对农业碳排放影响中的抑制作用不显著。【结论】促进数字农业建设与农业碳排放发展紧密融合,因地制宜发展数字农业,加快新质生产力的发展步伐,提升农业人力资本水平,全方位助推农业低碳发展。

【Objective】This study aims to explore the impact of digital agriculture construction on agricultural carbon emissions,tap the potential of emission reduction,and promote the development of low-carbon agriculture.【Method】Based on the panel data of 30 provinces(autonomous regions and municipalities directly under the Central Government)in China from 2013 to 2021,this study analyzed the impact of digital agriculture construction on the intensity of agricultural carbon emissions by using the fixed effect model,and conducted the test of the action mechanism to explore the mechanism of emi-ssion reduction.【Result】Digital agriculture construction has a significant inhibitory impact on the intensity of agricultural carbon emissions.There is significant heterogeneity in the impact of digital agriculture construction on agricultural carbon emissions,with a significant emission reduction effect in the eastern and western regions,but not in the central region.Digital agriculture construction indirectly affects the inhibitory effect on the intensity of agricultural carbon emissions through the human capital of agriculture,and the inhibitory effect of agricultural technological innovation in the impact of digital agriculture construction on agricultural carbon emissions is not significant,while agricultural technology innovation has an insignificant inhibitory effect in the impact of digital agricultural construction on agricultural carbon emissions.【Conclusion】Measures should be taken to promote the close integration of digital agriculture construction and agricultural carbon emission development,develop digital agriculture according to local conditions,accelerate the development of new quality productivity,improve the level of agricultural human capital,and promote low-carbon agricultural development in an all-round way.
