摘　　要：在混合寡占竞争模型的框架下提出三种政策协调方案,即通过征收进口关税、给予国内企业产量补贴或两者同时实施来配合国有企业民营化改革,进而探讨政策工具的优化策略选择对社会福利的影响。研究结果表明:在三种政策下,市场均衡价格均不等于国有企业的边际成本;从改善社会福利的角度,部分民营化始终是最优选择;通过福利分析,政府搭配民营化政策给予国内企业产量补贴虽然能够实现最高的消费者剩余,但在社会福利的排序中处于劣势。本文为部分民营化策略的实施以及产业、贸易政策的优化提供了理论依据,指出政府仅仅考虑对国内企业进行产量补贴可能并不是最优策略选择。This paper proposed three policy regimes in the framework of mixed oligopoly theory, that is through the combination of import tariffs, output subsidies or both, to examine the partial privatization and strategic industrial and trade policies in China. We then analyze the impact of policy options on social welfare. The results show that firstly, the market equilibrium price is not equal to the marginal cost in any policy sce- nario. Secondly, partial privatization is always the best choice from the prospective of improving social welfare. More interestingly, the highest customer surplus is achieved by the subsidies to the domestic enterprise, whereas the social welfare in this regime is lower. We provide theoretical basis for the implementation of partial privatization strategy and the optimal of the industrial and trade policies. Actually, it is not the optimal strate- gy choice that the government only considers output subsidies for domestic enterprises.
