📚 IGCSE OCR Business: Ratio Analysis Key Points | IGCSE OCR 商务：比率分析 考点精讲
Ratio analysis is a powerful quantitative tool used by stakeholders to evaluate the financial performance and position of a business. By comparing figures from the income statement and statement of financial position, managers, investors, and lenders can make informed decisions about profitability, liquidity, efficiency, and overall financial health.
比率分析是一种强有力的定量工具，利益相关者用它来评估企业的财务业绩和财务状况。通过比较利润表和财务状况表中的数据，管理者、投资者和贷款机构可以就盈利能力、流动性、效率和整体财务健康做出明智决策。
1. What is Ratio Analysis? | 什么是比率分析？
Ratio analysis involves calculating financial ratios from a company’s accounts to assess performance. Ratios allow for comparison over time (trend analysis) and against competitors (inter-firm comparison). They convert raw financial data into meaningful relationships that reveal strengths and weaknesses in a business.
比率分析涉及从公司账目中计算财务比率以评估业绩。比率可以用于跨时间对比（趋势分析）和与竞争对手对比（公司间比较）。它们将原始财务数据转化为有意义的关系，揭示企业的优势和劣势。
Two main groups use financial ratios: internal stakeholders such as managers who monitor operational efficiency, and external stakeholders such as shareholders, lenders, and suppliers who assess return on investment and creditworthiness. Each group focuses on different categories of ratios depending on their interests.
使用财务比率的两大群体是：内部利益相关者如监控运营效率的管理者，外部利益相关者如评估投资回报和信用的股东、贷款人和供应商。每个群体根据自身利益关注不同类别的比率。
2. Ratio Categories Overview | 比率类别概览
For IGCSE OCR Business, ratios are grouped into four main categories: profitability ratios, liquidity ratios, efficiency ratios, and leverage ratios. Profitability ratios measure how well a business generates profit from its resources. Liquidity ratios assess the ability to meet short-term obligations. Efficiency ratios evaluate how effectively the business uses its assets. Leverage ratios examine the financing structure and long-term solvency.
在IGCSE OCR商务中，比率分为四大类：盈利能力比率、流动性比率、效率比率和杠杆比率。盈利能力比率衡量企业利用资源创造利润的能力。流动性比率评估履行短期义务的能力。效率比率评估企业使用资产的效率。杠杆比率考察融资结构和长期偿债能力。
| Category 类别 | Focus 关注点 | Examples 示例 |
|---|---|---|
| Profitability | Profit generation | GPM, NPM, ROCE |
| Liquidity | Short-term survival | Current ratio, Acid test |
| Efficiency | Asset utilisation | Inventory turnover, Trade receivables days |
| Leverage | Debt reliance | Gearing ratio |
3. Gross Profit Margin (GPM) | 毛利率
Gross profit margin expresses gross profit as a percentage of revenue. It shows how efficiently a business converts sales into gross profit before deducting overhead expenses. A high or improving GPM suggests effective control over direct costs or the ability to charge premium prices.
毛利率将毛利表示为收入的百分比。它显示企业在扣除间接费用之前将销售转化为毛利的效率。毛利率高或持续提高表明对直接成本有有效控制或能够收取较高价格。
GPM = (Gross Profit / Revenue) x 100
Factors that increase GPM include raising selling prices while maintaining sales volume, negotiating lower cost of sales from suppliers, and improving production efficiency to reduce wastage. A fall in GPM may signal rising material costs, increased price competition, or inventory theft. Comparing GPM with industry averages helps assess competitive positioning.
提高毛利率的因素包括提高售价同时保持销量、从供应商处协商降低销售成本、提高生产效率以减少浪费。毛利率下降可能表明材料成本上升、价格竞争加剧或库存被盗。将毛利率与行业平均水平比较有助于评估竞争地位。
4. Net Profit Margin (NPM) | 净利率
Net profit margin measures the percentage of revenue that remains as net profit after all operating expenses, interest, and tax are deducted. It provides a more complete picture of overall profitability by accounting for overhead costs such as rent, salaries, and marketing.
净利率衡量在扣除所有运营费用、利息和税项后，作为净利润保留的收入百分比。它通过考虑租金、工资和营销等间接费用，提供更完整的整体盈利能力图景。
NPM = (Net Profit / Revenue) x 100
Improving NPM requires both gross profit management and tight control of operating expenses. Businesses can improve NPM by reducing administrative costs, renegotiating lease agreements, or streamlining staffing levels. A declining NPM while GPM remains stable indicates excessive overhead spending that needs investigation.
提高净利率需要同时管理毛利并严格控制运营费用。企业可以通过减少行政成本、重新谈判租赁协议或精简人员配置来提高净利率。在毛利率保持稳定的情况下净利率下降，表明存在需要调查的过度间接开支。
5. Return on Capital Employed (ROCE) | 资本回报率
ROCE is a fundamental profitability ratio that measures how efficiently a business generates profit from the total capital invested. It is widely used by investors to assess whether their capital is being deployed effectively. Capital employed equals total assets minus current liabilities, or alternatively, non-current liabilities plus total equity.
资本回报率是一个基本盈利能力比率，衡量企业从投入的总资本中创造利润的效率。它被投资者广泛用于评估其资本是否被有效使用。资本使用量等于总资产减去流动负债，或者非流动负债加上总权益。
ROCE = (Operating Profit / Capital Employed) x 100
A satisfactory ROCE exceeds the return available from risk-free investments and meets investor expectations given the industry risk profile. Businesses with high ROCE attract further investment more easily. To improve ROCE, management can increase operating profit without adding capital, or reduce capital employed by selling underperforming assets.
令人满意的资本回报率应超过无风险投资的回报，并满足投资者对该行业风险水平的预期。资本回报率高的企业更容易吸引进一步投资。为提高资本回报率，管理层可在不增加资本的情况下增加营业利润，或通过出售表现不佳的资产来减少资本使用量。
6. Current Ratio | 流动比率
The current ratio is a key liquidity measure that assesses a firm’s ability to settle short-term debts using its current assets. Current assets include cash, trade receivables, and inventory. Current liabilities comprise trade payables, short-term borrowings, and accrued expenses due within one year.
流动比率是衡量企业利用流动资产偿还短期债务能力的关键流动性指标。流动资产包括现金、应收账款和存货。流动负债包括应付账款、短期借款和一年内到期的应计费用。
Current Ratio = Current Assets / Current Liabilities
An ideal current ratio typically ranges between 1.5:1 and 2:1, though acceptable levels vary by industry. A ratio below 1:1 signals potential cash flow problems and insolvency risk. A ratio that is too high may indicate inefficient use of cash, excessive inventory holding, or poor collection of receivables.
理想的流动比率通常在1.5:1到2:1之间，尽管可接受水平因行业而异。比率低于1:1表明可能存在现金流问题和资不抵债的风险。比率过高可能表明现金使用效率低下、存货积压或应收账款回收不力。
7. Acid Test Ratio (Quick Ratio) | 速动比率
The acid test ratio provides a stricter liquidity assessment by excluding inventory from current assets. Inventory is the least liquid current asset and may lose value if sold quickly. This ratio therefore focuses on assets that can be converted to cash almost immediately.
速动比率通过将存货排除在流动资产之外，提供更严格的流动性评估。存货是流动性最差的流动资产，快速出售可能贬值。因此该比率关注几乎可以立即转化为现金的资产。
Acid Test Ratio = (Current Assets – Inventory) / Current Liabilities
A ratio of 1:1 or above is generally considered safe, meaning liquid assets fully cover current liabilities. Retailers often have lower acid test ratios because they hold significant inventory. A low acid test ratio alongside a reasonable current ratio suggests the business is overly dependent on inventory for liquidity.
1:1或以上的比率通常被认为是安全的，意味着速动资产完全覆盖流动负债。零售商往往速动比率较低，因为他们持有大量存货。速动比率低而流动比率尚可，表明企业过度依赖存货来维持流动性。
8. Inventory Turnover Ratio | 存货周转率
Inventory turnover measures how many times a business sells and replaces its inventory over a period. It can be expressed as a number of times per year or as an average number of days inventory is held. Efficient inventory management balances having enough stock to meet demand without tying up excessive capital.
存货周转率衡量企业在一个时期内销售和补充存货的次数。它可以表示为每年的周转次数，或存货持有的平均天数。有效的存货管理在满足需求的足够库存和不占用过多资金之间取得平衡。
Inventory Turnover = Cost of Sales / Average Inventory
A high turnover rate indicates strong sales and efficient stock management, reducing storage costs and obsolescence risk. However, excessively high turnover may signal frequent stockouts and lost sales opportunities. A low turnover rate suggests overstocking, obsolete inventory, or weak demand. Strategies to improve turnover include just-in-time ordering and better demand forecasting.
高周转率表明销售强劲和存货管理高效，降低存储成本和过时风险。然而，过高的周转率可能表明频繁缺货和销售机会丧失。低周转率表明存货积压、过时或需求疲软。提高周转率的策略包括准时制订购和更好的需求预测。
9. Trade Receivable Days | 应收账款周转天数
Trade receivable days, also called debtor days, shows the average time taken by credit customers to pay their invoices. This ratio directly impacts cash flow because longer collection periods mean cash is tied up in receivables rather than available for operations.
应收账款周转天数也称为债务人天数，显示赊销客户支付发票的平均时间。该比率直接影响现金流，因为收款期越长意味着现金被占压在应收账款中而无法用于运营。
Trade Receivable Days = (Trade Receivables / Credit Sales) x 365
Lower trade receivable days are generally preferred, reflecting efficient credit control and prompt customer payment. A rising trend may indicate poor collection procedures, overly generous credit terms, or customers facing financial difficulties. Businesses can reduce receivable days by offering early payment discounts, tightening credit policies, or employing dedicated collection teams.
较低的应收账款周转天数通常受青睐，反映有效的信用控制和客户及时付款。上升趋势可能表明收款程序不力、信用条款过于宽松或客户面临财务困难。企业可以通过提供提前付款折扣、收紧信用政策或聘用专门的收款团队来减少应收账款天数。
10. Trade Payable Days | 应付账款周转天数
Trade payable days measures how long a business takes to pay its suppliers. Extending payment periods can ease short-term cash pressure, but consistently delaying payments risks damaging supplier relationships and losing access to trade credit.
应付账款周转天数衡量企业支付供应商所需的时间。延长付款期可以缓解短期现金压力，但持续拖延付款有损供应商关系并可能失去赊购渠道。
Trade Payable Days = (Trade Payables / Credit Purchases) x 365
A high payable days figure improves immediate cash flow, effectively using suppliers as a source of interest-free finance. However, suppliers may refuse further credit, demand cash-on-delivery terms, or withhold future deliveries. Ethical considerations also arise, particularly for large businesses delaying payments to smaller suppliers.
较高的应付账款天数改善即时现金流，有效地将供应商作为无息融资来源。然而，供应商可能拒绝继续赊销，要求货到付款或停止未来交货。还会产生道德考量，尤其是大企业拖延向较小供应商付款时。
11. Gearing Ratio | 杠杆比率
The gearing ratio reveals the proportion of a business’s capital that comes from borrowing compared to shareholder funds. It indicates financial risk because high-geared companies must make mandatory interest payments regardless of profit levels. Lenders scrutinise this ratio when deciding whether to extend loans.
杠杆比率揭示企业资本中来自借款与股东资金的比例。它指示财务风险，因为高杠杆公司无论利润水平如何都必须支付强制性利息。贷款机构在决定是否放贷时仔细审查该比率。
Gearing Ratio = (Non-current Liabilities / Capital Employed) x 100
A gearing ratio above 50% is typically considered high-geared, meaning the business relies heavily on debt finance. High gearing amplifies returns for shareholders when profits are strong but poses severe risk during downturns when interest costs persist. Low-geared businesses have greater financial stability and borrowing capacity for future expansion.
杠杆比率超过50%通常被认为是高杠杆，意味着企业严重依赖债务融资。利润强劲时高杠杆放大股东回报，但在经济低迷时利息成本持续存在，构成严重风险。低杠杆企业具有更高的财务稳定性和未来扩张的借款能力。
12. Limitations of Ratio Analysis | 比率分析的局限性
Ratios provide valuable insights but must be interpreted with caution. They are based on historical financial data that may not accurately reflect current market conditions. Ratios only highlight symptoms, not causes, so further investigation is always required to understand underlying performance drivers.
比率提供有价值的见解，但必须谨慎解读。它们基于历史财务数据，可能无法准确反映当前市场状况。比率仅突显症状而非原因，因此始终需要进一步调查以了解潜在绩效驱动因素。
Different accounting policies for depreciation, inventory valuation, and revenue recognition can produce different ratio values even for similar businesses. Inflation distorts comparisons over time, particularly for assets valued at historic cost. Additionally, ratios ignore qualitative factors such as brand reputation, employee morale, and customer loyalty that fundamentally affect long-term success.
不同的折旧、存货估值和收入确认的会计政策即使对类似企业也可能产生不同的比率值。通货膨胀扭曲跨时间对比，尤其是对以历史成本计价的资产。此外，比率忽略了根本影响长期成功的定性因素，如品牌声誉、员工士气和客户忠诚度。
