股权结构对企业经营绩效影响的区域差异研究

A Study of the Impact of Ownership Structure on Corporate Operating Performance’s Regional Differences

为了检验我国仅发行A股的上市公司股权结构对企业经营绩效影响的区域差异,文章选取了2018-2020年三年均在沪深两市发行A股的上市公司为研究对象,通过SPSS软件,从股权属性和股权集中度两个方面对我国东部、中部和西部地区的上市公司分别进行均值统计分析和实证检验。经过研究,发现上市公司国有股比例对经营绩效无显著影响;法人股比例、流通股比例、前五大股东持股比例之和与股权制衡度对经营绩效的影响存在地区差异性。根据上述结论,文章为我国东部、中部和西部地区上市公司完善股权结构分别提出了对应的策略建议。

In order to test the regional differences in the influence of the equity governance structure on operating performance of A-share listed companies,the article selected listed companies that only issued A shares in Shanghai and Shenzhen from 2018 to 2020 as the research object.Mean statistical analysis and empirical tests were carried out by SPSS software in the eastern,central and western regions from two aspects of equity attributes and equity concentration.The study found that the proportion of state-owned shares has no significant impact on operating performance;there are regional differences in the impact of the proportion of legal person shares,the proportion of outstanding shares,the proportion of shares held by the top five shareholders,and the equity balance on operating performance.Based on the above conclusions,corresponding countermeasures and suggestions are put forward.
