1. "Operating profit" is not "total profit"
2. Quick ratio = (current assets inventory)/current liabilities
3. Return on net assets = net profit of the current year/net assets at the end of the year.
4. Net assets per share = net assets at the end of the year/registered capital at the end of the year
5. Accounts receivable turnover rate = operating income of the current year [(accounts receivable at the beginning of the year+accounts receivable at the end of the year) /2]6. Inventory turnover rate = main business cost of this year/[(inventory amount at the beginning of the year+inventory amount at the end of the year) /2]6. Gross profit margin = (main business income-main business cost)/main business income.
7. Basic earnings per share (RMB) = net profit/year-end registered capital
8. If there is a big difference between the two years' indicators, please ask the enterprise for the reasons first.
