This article presents a dynamic general equilibrium model of mixed oligopoly. In this model,public firms engage in manufacturing differentiated goods and cost-reducing R&D investments.This paper shows that public firms suddenly disappear from the mixed oligopoly market when the parameter of competitiveness exceeds the threshold value. This paper also shows that subsidies are larger when public firms regard a representative household as more important.
