This essay analyzes the member participation in general as-sembly and educational committees in agricultural cooperatives in func-tion of economic objective function, members’ number, and economic performance. There are analyses of two regression models that show the participation is an inverse function of economic performance in coopera-tives and the educational committee participation occurs in functions to intensify the member relations in cooperative with problems with mem-ber economic activity. At the end it is possible also indicate that member participation is important to corporate governance transparency in agri-cultural cooperative but there is a dichotomy because the best economic performance in cooperatives could not incentive member participation and in consequence the governance transparency that needs additional costs to correct this deficiency.
