农村劳动力老龄化对耕地碳排放的影响研究OACHSSCD

Achieving low-carbon emissions from cultivated land is crucial for promoting sustainable agricultural development.To clarify the micro-level impact of rural labor force aging on cultivated land carbon emissions and its underlying mechanisms,this study conducts a series of empirical test by employing least squares regression and mediation effect model based on survey data from 848 grain-farming households along Yellow River basin in Shandong Province.The findings reveal:1)Rural labor force aging significantly reduces carbon emission intensity from farmland,a conclusion that holds after a series of endogeneity and robustness tests.2)Mechanism analysis from the perspective of production decision adjustments indicates that achieving large-scale farmland management,accelerating agricultural technological progress,and enhancing agricultural socialized services are three key pathways through which rural labor force aging influences farmland carbon emission intensity.3)Heterogeneity analysis reveals that the suppression effect of rural labor force aging on arable land carbon emissions is more pronounced in regions with higher household income levels,higher education attainment,and larger arable land scales.Based on these findings,a policy combination is proposed:guiding the realization of intensive and scaled arable land management,promoting green agricultural technological innovation,and improving the socialized service system.This approach transforms the pressure of labor force aging into new momentum for green arable land production,providing micro-level evidence for achieving the"dual carbon"goals.
