Abstract: The protection of farmers’ rights and interests is facing a major practical problem of the status of farmers in vulnerable groups. In order to prevent farmers from getting deeper and deeper in the vortex of vulnerable groups, it is necessary to specify the principles of economic law from the perspectives of balance and coordination, fairness and efficiency, extreme promotion and extreme restrictions, and to protect farmers' rights from this perspective. In order to evaluate the effect of economic law on the protection of farmers' rights and interests, the PSR-AHP model was introduced to construct an evaluation index system, and an empirical analysis was conducted using Shaanxi province as an example. The results show that economic law has a certain effect on the protection of farmers’ rights and interests, but there is a certain lag in the legislative and law enforcement levels. Future economic law reforms need to be improved from these two aspects in order to truly exert the effectiveness of protecting peasants' rights and interests.

Key words: economic law, farmers' rights and interests, protection effect, PSR-AHP model
