摘要
本文通过构建一个国有企业混合所有制的混合寡头模型,分析了当私有企业生产存在负外部性时国有企业混合所有制对社会净福利的影响。本文发现,当混合改制前的成本不超过某个临界值时,国有企业可以实现混合所有制经营,从而给出了国有企业混合所有制改革的内在机制。进一步,本文给出了政府是否需要对国有企业进行混合所有制改造的外在条件,即当行业负外部性对社会福利的损害程度不是太大时,政府推行混合所有制改革可以最大化社会净福利。国有企业最优的混合比例取决于国有企业自身承担社会性负担的能力和社会性负担的大小,具体而言,国有企业最优的混合比例跟其成本控制能力、产品差异化程度、行业内私有企业数目以及生产负外部性对社会福利的损害程度存在负相关关系。基于理论分析,本文给出了当前国有企业的混合所有制改革的相关政策建议。
This paper constructs a mixed oligopoly model to analyze the mixed ownership reform of stated-owned enterprises. We focus on the impact of the mixed ownership reform on the net social welfare when private firms produce negative externalities. When the prereform cost does not exceed a critical value,the mixed ownership is feasible. This gives the intrinsic mechanism of the mixed ownership. Furthermore,we give the conditions under which stated-owned enterprises adopt the mixed ownership or not,and find that the mixed ownership can maximize the net social welfare when the damage degree of negative externalities of the related industry is not too large. The optimal mixed proportion depends on the stated-owned enterprises′ ability to undertake the social burden and the size of the social burden. Specifically,the optimal mixed ratio is negatively related to the stated-owned enterprises′ ability to control the operation cost,the degree of product differentiation,the number of private firms in the related industry,and the damage degree of negative production externalities. We give some related policy suggestions on the basis of our theoretical analyses.
