Abstract:Based on the Theory of Planned Behavior, Staking advantage of the survey data from Henan, Shandong and Hubei 132 scale farmers,constructing the theoretical model of the scale farmers" participation in product quality tracing,using structural equation method to empirically analyze the influencing factors and its effect on the scale of rural households" participation in agricultural product quality tracing,so we can solve the internal mechanism of the participation behavior of the scale farmers.The research results show that expected benefits, participation costs and future expectations of the scale farmers have more effect on the behavior and attitude of farmers and the behavior attitude has a significant influence on the participation intention and participation behavior;Scale farmers feel from the government and the family of the group norms, peer competitive pressure and other factors significantly effect their subjective norms,and then the influence of their participation intention and participation behavior;The cognition of scale farmers" self ability, familiarity with the policy and their own energy significantly affect their control, and through controlling the transmission of cognitive function in their intention and participation behavior.This paper focuses on the size of the sub groups of farmers,and the current research on the quality of the farmers involved in tracing the behavior of the deepening of its decision-making mechanism to explain the breakdown of the field.In this paper, the research work and the findings will provide reference value for the follow-up theory research and practice.
