【摘要】 当前我国国有企业已经进入全面深化改革的新阶段,2020年中央深改委通过的《国企改革三年行动方案(2020-2022年)》明确指出,要分层次按不同类别积极稳健地推行国有企业分类改革,分类改革已成为我国当前及未来的改革主旋律。2015年我国开始实行国有企业分类改革,以国有企业的职能目标为根据,将国有企业划分为商业类和公益类,制定差别化的改革道路,并按类别进行不同的监督和考核管理,使我国国有企业实现社会绩效和经济绩效的有机统一。因此对分类改革政策与国有企业经济社会综合绩效的研究具有指导国有企业继续深化改革的理论价值和现实意义。本文考察了股权集中度在分类改革对国有企业经济社会综合绩效影响中的中介作用,有助于优化国有企业的股权结构。本文从理论和实证两个层面展开论证。首先,通过整理国有企业分类改革、股权集中度和国有企业经济社会综合绩效的相关文献,对我国国有企业分类改革的历程进行了回顾,并从经济绩效和社会绩效两个维度对国有企业综合绩效的发展状况进行了阐述和分析,以了解我国国有企业综合绩效的发展现状。其次,从理论层面,分析了三者之间的相互影响。再次,利用2013-2019年上市公司数据,采用PSM-DID的方法,考察分类改革对国有企业经济社会综合绩效的总体影响。接着将国有企业划分为三种不同的类型,分别考察分类改革政策对不同类型国有企业经济社会综合绩效的影响差异,并把股权集中度作为中介变量,探究股权集中度的差异和不同类型国有企业经济社会综合绩效的关系。最后,针对研究结果提出政策建议。研究结果发现:第一,分类改革政策对国有企业整体的综合绩效产生了显著的影响,即实施分类改革政策后,国有企业总体的经济绩效显著的提升了;社会绩效方面,分类改革政策降低了国有企业员工和消费者的利益,但提高了政府的利益。第二,分类改革政策实施后,商业类国有企业的经济绩效显著提升了,且特殊功能性商业类国企经济绩效提升程度优于竞争性商业类国企;公益类国有企业社会绩效中的员工人数及营业成本率有明显的上升,但由于分类改革政策后公益类国有企业经济绩效的下降,政府纳税贡献率也有所下降。第三,分类改革政策实施后,商业类国有企业的股权集中度有所下降,公益类国有企业的股权集中度有所提高。股权集中度与国有企业的经济绩效负相关;与国有企业的社会绩效正相关,且股权集中度在分类改革政策对不同类型国有企业经济社会综合绩效影响中的中介效应存在。更多还原

【Abstract】 At present,my country’s state-owned enterprises have entered a new stage of comprehensively deepening reform.The "Three-year Action Plan for State-owned Enterprise Reform(2020-2022)" adopted by the Central Deep Reform Commission in2020 clearly states that state-owned enterprises must be actively and steadily implemented at different levels and in different categories.Classification reform,classification reform has become the main theme of my country’s current and future reforms.In 2015,my country began to implement the reform of the classification of state-owned enterprises.Based on the functional objectives of state-owned enterprises,state-owned enterprises were divided into commercial and public welfare categories,and differentiated reform paths were formulated,and different supervision and assessment management according to categories were carried out to enable state-owned enterprises in our country.Realize the organic unity of social performance and economic performance.Therefore,the research on classified reform policies and the comprehensive economic and social performance of state-owned enterprises has theoretical value and practical significance to guide state-owned enterprises to continue to deepen reforms.This paper examines the mediating role of equity concentration in the impact of classification reform on the comprehensive economic and social performance of state-owned enterprises,which helps to optimize the ownership structure of state-owned enterprises.This article starts the argument from two levels of theory and empirical research.First,it sorts out the relevant literature on the classification reform of state-owned enterprises,the concentration of equity and the comprehensive performance of state-owned enterprises,reviews the history of the classification reform of state-owned enterprises in my country,and examines the development status of the comprehensive performance of state-owned enterprises from the two dimensions of economic performance and social performance.Explain and analyze to understand the development status of my country’s state-owned enterprises’ comprehensive performance.Secondly,from the theoretical level,the interaction between the three is analyzed.Thirdly,using the data of listed companies from 2013 to 2019,using the PSM-DID method,to examine the overall impact of classification reforms on the comprehensive economic and social performance of state-owned enterprises.Next,state-owned enterprises are divided into competitive commercial state-owned enterprises,special-functional commercial state-owned enterprises,and public welfare state-owned enterprises,respectively,to examine the impact of classification reform policies on the comprehensive economic and social performance of different types of state-owned enterprises,and use equity concentration as an intermediary variable to explore equity concentration The relationship between the degree of difference and the comprehensive performance of different types of state-owned enterprises.Finally,policy recommendations are made based on the research results.The results of the study found that: First,the classification reform policy has had a significant impact on the overall performance of state-owned enterprises,that is,after the classification reform policy,the overall economic performance of state-owned enterprises has been significantly improved;in terms of social performance,the classification reform policy has reduced the performance of state-owned enterprises.The interests of employees and consumers have improved the interests of the government.Second,after the classification reform policy,the economic performance of commercial state-owned enterprises has improved significantly,and the economic performance of special-functional state-owned enterprises has improved better than competitive state-owned enterprises;the number of employees and operating cost ratios in the social performance of public welfare state-owned enterprises have increased significantly However,due to the decline in the economic performance of public welfare state-owned enterprises after the classification reform policy,the tax contribution rate of the government has also declined.Third,after the classification reform policy,the shareholding concentration of commercial state-owned enterprises has declined,and the shareholding concentration of public welfare state-owned enterprises has increased.Equity concentration is negatively correlated with the economic performance of state-owned enterprises;it is positively correlated with the social performance of state-owned enterprises.Moreover,the mediating effect of equity concentration in the impact of classification reform policies on the comprehensive economic and social performance of different types of state-owned enterprises exists.更多还原
