摘　　要：本文构建古诺博弈模型分析开放环境下民营化程度对政府最优产业(或贸易)政策选择的影响及由此带来的社会福利的变化。核心结果表明:从最大化社会福利出发,生产补贴政策是政府的最优战略选择。最优生产补贴下,推进民营化可以提高社会福利水平。企业进行产量竞争时,最优生产补贴与民营化程度呈U型关系;进口关税与民营化程度呈正向相关关系,贸易政策下社会福利与民营化程度呈倒U型关系。企业进行价格竞争时,最优生产补贴与民营化程度呈倒U型关系。最后,探讨了生产补贴的作用。Based on an international mixed oligopoly model; this article investigates the effects of partial privatization on the optimal strategic policy and the social welfare in the international mixed market. The results show that： Considering in terms of social welfare maximization, subsidies policy is the optimal choice. With the optimal subsidies, promoting the degree of privatization can improve social welfare. In addition, we found that under the quantity competition, the relationship between the optimal production subsidies and the degree of privatization is a U-shaped curve ; for the trade policy, the relationship between import tariffs and the degree of privatization is positive, and the relationship between the social welfare and the degree of privatization is an inverted U-shaped curve. Under the price competition, the relationship between the optimal production subsidies and the degree of the privatization is an inverted U-shaped curve, for the trade policy. Finally, as an application, this paper discusses the role of industrial policy.
