In this paper, we develop a three-level supply chain network equilibrium model with multi products and multicriteria based on corporate social responsibility through integrating the maximization of economic benefits, the maximization of social utility and the minimization of environment pollution. Competitive behavior of manufactures and retailers in a no cooperative competitive is analyzed and the multicriteria decision-making behavior is described by using Nash equilibrium theory and the weighted value function. Products utility functions of brand differentiation and consumer preferences from product price, transaction cost and corporation social responsibility are used to analyze product choice in a market, and the optimization conditions of each tier and whole network are developed by variational inequality method. At last we illustrate the model with several numerical examples.
