【摘要】 产权和生产率的关系一直是发展经济学研究的热点,而中国新一轮的农地确权为探究两者的关系提供了一个良好的外生自然实验。本文利用浙江大学中国家庭大数据库(CFD)2015年和2017年的数据,通过面板固定效应模型,研究了农地确权政策是否、多大程度上以及如何影响农地生产率。研究结论显示,农地确权会显著提高农地生产率(3.7%),且其效应存在时间异质性。对确权1年以内的农户没有影响,但能显著提高确权1年以上农户的农地生产率(5%)。进一步的机制探究发现,稳定的产权能增加农户对农地的长期投资,同时加速农户的农地流转行为,进而提升农地生产率。更多还原

【Abstract】 The relationship between property rights and productivity has always been the focus in the field of development economics, and China’s new round of agricultural land certification provides a good exogenous natural experiment to explore the relationship between them. Using the data of China Family Database(CFD)of Zhejiang University in 2015 and 2017, this article analyzes whether, to what extent and how the rural land certification policy affects rural land productivity. The results show that the certification of agricultural land will significantly improve the productivity of agricultural land(3.7%), and its effect has time heterogeneity. The impact of certification on agricultural land productivity is not significant within one year, but the long term impact is significant(5%). Further mechanism analysis shows that stable property rights can increase farmers’ long-term investment, accelerate farmers’ agriculturalland transfer, and improve agricultural land productivity.更多还原
