Abstract: Based on CLDS 2014 data, an empirical analysis of the relationship between land security and agricultural operating income is conducted. The results show that land rights have promoted the growth of farmers' family agricultural operating income, and combined with the heterogeneity of farmers' groups, it has been found that land rights are more favorable for agricultural production professionals and farmers who are mechanized and semi-mechanized. Land confirmation has enabled farmers with stronger resource endowments to achieve resource enhancement. In addition, combined with the research results, the policy recommendations for perfecting the land security system, improving the rural social security system, and effectively stabilizing land management rights are proposed.

Key words: land confirmation, agricultural operating income, resource strengthening, resource substitution
