内容提要:混合寡头理论自20世纪80年代诞生以来,逐渐成为国际经济学界中研究国有经济问题的主流框架之一。本文通过梳理混合寡头理论的演化脉络,重点评述有关混合所有制经济研究中的最优国有资本比例,税收、补贴等其他政策与国有经济改革的关系,外国资本与国家安全等维度的节点文献。在混合寡头理论中,以社会福利最大化为根本的混合寡头理论模型的最优解既不是完全国有的不改革,也不是彻底民营化的激进改革,而是相机而动的渐进改革。生产成本、企业数量、产品差异、跨国竞争、政府补贴以及市场准入壁垒等,都会影响混合所有制改革中社会合意的国有资本比重。鉴于我国正在推进混合所有制改革,在国内学界推广混合寡头理论,使这个国际主流理论体系得到“中国经验”、“中国模式”的反馈和滋润,具有现实基础和理论意义。
Abstract: Since oligogenic theory was born in the 1980s, it has gradually become one of the mainstream frameworks for studying state-owned economy in international economics circle. By combing the evolutionary context of mixed oligopoly theory, this paper focuses on the peer literature on the dimensions of the optimal state-owned capital in the study of mixed ownership, the relationship between other policies such as taxes and subsidies and the reform of state-owned economy, foreign capital and national security. In the mixed oligopoly theory, the optimal solution of the mixed oligopoly model based on the maximization of social welfare is neither state-owned non-reform nor radical reform for complete privatization, but a camera-based progressive reform. Production costs, number of enterprises, product differentiation, cross-border competition, government subsidies and market access barriers all affect the proportion of state-owned capital that is socially desirable in the mixed ownership reform. In view of the fact that our country is advancing the reform of mixed ownership system and promoting the mixed oligarchic theory in the domestic academic circles, the feedback and nourishment of this international mainstream theoretical system by “China experience” and “China mode” have realistic and theoretical significance.
