This paper mainly analyzes the impact of ownership concentration on corporate financial performance from the perspective of ownership structure and company financial performance. The equity concentration is mainly demonstrated from the proportion of the largest shareholder's shareholding, and the financial performance is mainly demonstrated from three aspects: solvency, operating ability, and profitability. It is to study whether the ownership structure is related to the financial performance of the retail industry and how to pass change corporate ownership structure to improve corporate financial performance. Based on the analysis of the ownership structure and financial performance data of 14 retail companies in the “2021 Fortune 500”, EViews 10 software was used to process the data. Results of the study demonstrate that when the state-owned holding factor is included, the shareholding ratio of the largest shareholder has a significant negative correlation with company performance. This also means that, for enterprises in the retail industry, the higher the degree of equity concentration of the enterprise, the less conducive to the growth of the financial performance of the enterprise.
