地权稳定性对农户耕地质量保护行为的影响——基于新一轮确权颁证调节效应的分析

Impact of Land Tenure Stability on Farmer s Cultivated Land Quality Protection Behavior:Analysis Based on Adjustment Effect of the New Round Land Certification

基于广西的农户调查,考察了地权稳定性对农户耕地质量保护行为的影响,并检验了新一轮确权颁证在其中的调节效应。研究表明,地权不稳定会显著负向影响农户耕地质量保护行为,二轮承包期间的土地大调整经历会降低农户施有机肥的可能性,土地小调整经历则不利于农户采用秸秆还田技术。当前正在推进的新一轮农地确权颁证在地权稳定性和农户耕地质量保护行为间发挥着显著调节作用,以提升产权安全性为目标的农地确权会削弱地权稳定性带来的负面影响。子样本检验、替代变量检验和Biprobit模型证实上述发现是稳健的。此外,对于秸秆还田行为,研究发现农地确权存在时滞效应,随着颁证时间延长,确权能更好地消除地权不稳定带来的负面影响。鉴于农地确权颁证有着积极的政策效应,能够削弱地权不稳定带来的负面影响,因此要以新一轮确权为契机,保持地权长期稳定,让新一轮确权有效保护农户地权,激励农户积极保护耕地质量。

This paper takes the survey in Guangxi Zhuang Autonomous Region as an example to examine the impact of land tenure stability on farmer s cultivated land quality protection behavior and examines the regulatory effect of the new round of confirmation of land ownership right on land tenure stability and farmer behavior.The research results show that instability of land rights could significantly negatively affect farmers adoption of arable land quality protection measures and reduce the possibility of farmers adopting protective behaviors.The large-scale land adjustment experience during the second round of contracting could reduce the possibility of farmers applying organic fertilizer,and the small-scale land adjustment experience is not conducive to farmers adoption of straw return technology.Further research finds that the current new round land certification is playing a significant role in regulating the stability of land rights and the protection of farmer s cultivated land quality.The determination of land rights for improving the security of property rights could weaken the stability of land rights.The subsample test,a test that uses an alternate variable and the Biprobit model test all confirm that the above findings are robust.In addition,with regard to the behavior of farmers returning straw to the field,it is found that there is a time lag effect in confirming the right to agricultural land.In view of the positive policy effects of the confirmation of land tenure,it will weaken the negative impact of the instability of land tenure in history.Therefore,it is necessary to take the new round of confirmation of land tenure as an opportunity to maintain long-term stability of land tenure and let the new round land certification effectively protect farmers land property rights and encourage farmers to actively protect arable land.
