This article aims to assess the impact of issuing land rights certification on farmers' operating behavior. To accomplish this objective, this paper establishes a theoretical framework for farmers' management behavior and thoroughly examines the stability, endowment, and security effects of land rights certification. Subsequently, using household survey data, the Probit and propensity score matching (PSM) estimation methods are employed to empirically substantiate the influence of farmland ownership confirmation. The verification results show that land right confirmation tends to motivate farmers to engage in agricultural management, and encourages female and older laborers to be more involved in agricultural production compared to males and younger laborers. Furthermore, the paper explores the mechanism by introducing such indicators as investment in agricultural machinery, quality of cultivated land, non-agricultural income of farmers, and laborers’ insurance status. Through analysis and testing, this paper holds that land right confirmation has a dual impact on farmer management, and when the reverse effect is limited, farmers are prompted to adjust the contradiction through labor force allocation within the family.
