In recent years, the existence of a "social divide", comprising factors such as income and professional status, has been noted as one significant type of social issue. It has been stated that, among the disparate groups, a member belonging to one group cannot move to any other groups. Such a rigidity in terms of social status results in non-activation of the economy. In this study, we have suggested a dynamic economic model described by a multi-agent system, and have evaluated its dynamics in order to try to understand the mechanisms by which how the social divide emerges within the model. We used Gini's coefficient to evaluate the social divide and its economic efficiency. As a result, it is suggested that economies under conditions of low competitiveness, being a state composed of relatively more consumer agents than producer agents, display a higher negative relationship between Gini's coefficient and economic efficiency than those under conditions of high competitiveness.
