混合所有制经济是社会主义基本经济制度的重要实现形式.本文从企业之间的竞争关系出发,实证检验了竞争对手混合所有制结构对上市公司投资效率的影响.研究结果显示,竞争对手混合所有制结构显著提高了上市公司的投资效率;竞争机制是这一影响产生的主要路径.异质性分析表明,竞争对手混合所有制结构对上市公司投资效率的影响,在上市公司产权性质方面没有显著差异,但在上市公司竞争压力更大、董事长与总经理非两职合一以及分析师关注程度更高时更显著.进一步分析表明,竞争对手混合所有制结构通过抑制过度投资和缓解投资不足两个方面同时提高了企业的投资效率.由此可见,混合所有制改革存在一定的外部性,因此需要在混合所有制推动和发展过程中统筹资本市场和产品市场两侧,提高上市公司质量.
Mixed Ownership Structure of Peer Firms and Investment Efficiency of Listed Enterprises
Mixed ownership economy is an important form of realizing the basic socialist eco-nomic system.Most existing studies discuss the consequences and value of mixed ownership structure from the perspective of mixed-ownership enterprises.However,there is no direct answer from theo-retical or empirical studies on how the introduction and diffusion of mixed ownership will affect other companies and even the overall operation of market economy.Starting from the competition relation-ship between enterprises,this paper empirically tests the influence of the mixed ownership structure of competitors on the investment efficiency of listed enterprises.The main findings are as follows:the mixed ownership structure of competitors significantly improves the investment efficiency of listed en-terprises.Competition mechanism is the main mechanism of this influence.Heterogeneity analysis shows that this influence has no significant difference in state owned enterprises and non-state-owned enterprises.However,it is more significant when the competitive pressure of listed companies is greater,the chairman and the general manager are not in one and the analysts are more concerned.Further analysis shows the mixed ownership structure of competitors can improve the investment effi-ciency of enterprises by restraining over-investment and alleviating under-investment.In theory,this study provides evidence for the economic consequences of mixed ownership that differs from existing research.In practice,the findings of this study show that mixed ownership reform has certain exter-nalities,so it is necessary to coordinate both the capital market and the product market in the process of promoting and developing mixed ownership,and improve the quality of listed companies.
