摘要
基于喀斯特地区2019—2021年6219份农户样本数据,运用双向固定效应模型剖析农村劳动力流失对耕地绿色利用的直接影响,并进一步分析农村劳动力流失通过种植结构调整产生的间接影响。研究结果表明:农村劳动力流失对耕地绿色利用呈显著负向影响,且该结论在经过内生性检验后仍然成立。种植结构调整在农村劳动力流失对耕地绿色利用的影响中发挥了间接效应,其中复种指数下降和“非粮化”分别会强化和弱化农村劳动力流失对耕地绿色利用的影响。
Based on the sample data of 6219 households in the karst areas of China,the direct effect of rural labor force loss on the green cultivated land utilization has been analyzed and the indirect influence of rural labor force loss on the adjustment of planting structure has been further studied by using the two-way fixed effects model.The results show that rural labor force loss has a negative impact on the green cultivated land utilization and the findings still hold true after endogeneity test.The adjustment of planting structure has an indirect effect on the influence of rural labor force loss on green cultivated land utilization.Among them,the decline of multi-cropping index and“non-grain”could strengthen and weaken the impact of rural labor force loss on cultivated land green utilization respectively.
