摘　　要：耕地质量事关农业可持续发展,基于广西壮族自治区818份调研问卷,探索并验证新一轮确权对农户耕地质量保护行为的影响。研究发现,新一轮确权能够有效激励农户采纳土壤肥力提升和养分平衡行为,激励农户更多采纳保护性耕作行为。具体表现为:确权颁证增加了农户施用有机肥、施测土配方肥和施石灰三类行为的概率,提升了农户采纳秸秆还田、免耕和深松三类技术的可能性。考虑到确权颁证的内生性和不同耕地质量保护行为相互之间可能的关联,分别使用PSM模型和Mvprobit模型进行稳健性检验,依然支持上述发现。进一步分析表明,确权颁证的政策效应有滞后性,相对持有确权证期限较短的农户,持有确权证期限较长的农户更可能采纳上述各类耕地质量保护行为。并且,农地确权对部分类型耕地质量保护行为的影响受到土地调整经历的负向调节,二轮承包期间经历过土地调整会削弱新一轮确权对农户施有机肥、施石灰和采纳免耕技术三类保护性措施的激励作用。The quality of cultivated land is related to the sustainable development of agriculture.Based on 818 questionnaires from the Guangxi Autonomous Region,this paper explores and verifies the impact of a new round certification on farmers’cultivated land quality protection behavior.The results show that this certification can effectively encourage farmers to adopt the behavior to improve soil fertility and nutrient balance and more protective tillage behavior.Specifically,land certification can increase farmers’probability to apply organic fertilizer,soil-testing formula fertilizer and lime,and possibility to adopt straw returning,no-tillage and sub-soiling technologies.Considering the possible endogenous traits and connections between different farmland quality protection behaviors,this paper uses PSM models and Mvprobit models to conduct the robustness test,and the above conclusions are still supported.Further analysis shows the stagnation of policy effect of certification.Specifically,farmers holding certification for a long period are prone to adopt behaviors protecting cultivated land quality,compared with those with certification for a short period.Moreover,the impact of land certification on the quality protection of some types of arable land is negatively regulated by the experience of land adjustment,which is expected to weaken the incentive effect of the new round certification on land consolidation on farmers to apply organic fertilizer,lime and no-tillage technology.
