城乡融合对农业碳排放强度的影响研究

Research on the impact of urban-rural integration on the carbon emission intensity of agriculture

发挥城乡融合对农业碳排放强度的抑制作用,对促进农村绿色低碳转型以及助力农业农村现代化具有重要的现实意义。本文基于城乡融合发展理论,利用2005—2020年30个省(市、区)面板数据,采用经典面板模型分析城乡融合对农业碳排放强度的影响,并探讨了其作用机制和异质性。结果表明,全国和三大区域(东、中、西部地区)的城乡融合发展水平呈持续上升趋势,而农业碳排放强度则呈显著下降趋势,两者之间的波动趋势呈相反态势。城乡融合对农业碳排放强度具有显著的负向影响。基于地理区位和粮食生产地区分析,城乡融合对东部地区和粮食主产区的农业碳排放强度抑制作用更为明显;城乡融合通过提高农业技术进步和农业规模化经营来抑制农业碳排放强度。为此,积极推动精准的城乡融合政策,加强农业技术进步和农业规模化经营,重视城乡融合减排效应的差异性,是实现降低农业碳排放强度的关键方向。

Leveraging the role of urban-rural integration in curbing agricultural carbon emissions intensity holds significant practical value for promoting low-carbon transitions in rural areas and advancing agricultural and rural modernization.Grounded in the theory of urban-rural integration development,this study employs a classical panel model to examine the impact of urban-rural integration on agricultural carbon emissions intensity.Using panel data spanning 2005 to 2020 from 30 provinces(cities,districts),the study delves into the mechanisms and heterogeneity of this relationship.Results reveal an ongoing upward trajectory in national and regional(eastern,central,and western)urban-rural integration development,juxtaposed with a notable decline in agricultural emissions intensity—opposite fluctuation trends.Urban-rural integration significantly dampens the intensity of agricultural carbon emissions.Further analyses spotlight a pronounced suppression of emissions intensity in the eastern region and major grain-producing areas due to urban-rural integration.Moreover,the urban-rural integration achieves this by bolstering agricultural technology advancement and scaling operations.To this end,proactive promotion of targeted urban-rural integration policies,reinforcement of agricultural technology progress and scaled operations,and recognition of emission reduction divergence are pivotal for curbing agricultural carbon emissions intensity.
