摘要：This paper analyzes a mixed duopoly in which a public firm and a (possibly partially) foreign-owned firm choose their capacity scales before competing in quantities. We show that the private firm chooses over-capacity, as in previous literature, except if it is completely foreign-owned. In this polar case, the private firm chooses the cost-minimizing capacity scale. We also show that the change in the nationality of the private firm does not essentially alter the public firm's choice, since this firm chooses under-capacity if products are substitutes and over-capacity if they are complements, just as it does when it faces a domestic competitor.
