农业商业化与生产率：来自中国农村土地市场参与的实证证据
Agricultural commercialization and productivity: Evidence from land market participation in rural China
摘要
This study utilizes nationally representative panel data on rural Chinese households to investigate the interrelationship between smallholders’ participation in land rental markets and their agricultural commercialization while also evaluating the interactive effects of these market‐oriented farming practices on agricultural land and labor productivity. We adopted a bivariate Tobit model, fixed effects models, and instrumental variable methods to address the endogeneity problems. Results reveal a mutually reinforcing relationship between farm households’ land rental area and commercialization decisions. Furthermore, renting farmland is associated with improved agricultural labor productivity and reduced land productivity. Agricultural commercialization shows a positive correlation with the productivity of both land and labor for farm households. Finally, commercialization could positively moderate the association between land renting and agricultural productivity. Policymakers should design policies and strategies to promote the development of the land rental market and the commercialization of farmers, which could improve labor and land productivity.
中文摘要
本研究利用具有全国代表性的中国农村家庭面板数据，探讨小农户参与土地租赁市场与其农业商业化之间的相互关系，同时评估这些市场化农业实践对农业土地和劳动生产率的交互效应。我们采用双变量Tobit模型、固定效应模型和工具变量方法来解决内生性问题。结果显示，农户土地租赁面积与商业化决策之间存在相互促进的关系。此外，租赁耕地与农业劳动生产率提高和土地生产率下降相关。农业商业化与农户土地和劳动生产率均呈正相关。最后，商业化能够正向调节土地租赁与农业生产率之间的关系。政策制定者应设计促进土地租赁市场发展和农民商业化的政策与策略，从而提升劳动和土地生产率。
