Abstract: Taking Bright Dairy as an example, this paper analyzed the return on net assets,operating net profit margin,total asset turnover ratio,equity multiplier and other indexes of the enterprise in 2018-2023 by DuPont Analysis,and compared them with the enterprises in the same industry,such as Mengniu Dairy and Yili shares. The analysis found that Bright Dairy's return on net assets increased,operating net profit margin improved,and anti-risk ability improved,but there were also problems such as poor cost and expense control,weak turnover of accounts receivable and inventory,and unreasonable capital structure,etc. It is recommended to strengthen cost control,accelerate the turnover of accounts receivable and inventory,and reasonably utilize financial leverage, and other strategies.
