本文梳理了苏格兰SQA 12年级（Higher）会计的核心知识点。内容涵盖会计基本原理、调整事项、财务报表编制、比率分析、预算以及不完全记录。无论你是在准备模拟考还是期末大考，透彻掌握这些重点都将帮助建立信心，应对各类考题。
1. Accounting Equation and Double-Entry | 会计等式与复式记账
Accounting is built on the fundamental equation: Assets = Liabilities + Owner’s Equity. Every transaction is recorded using the double-entry system, where total debit entries always equal total credit entries.
会计建立在以下基本等式之上：资产 = 负债 + 所有者权益。每一笔交易都采用复式记账法进行记录，借方总额与贷方总额始终保持相等。
Debits increase assets and expenses, while credits increase liabilities, capital and income. For example, when a business buys inventory on credit, the inventory account (asset) is debited and a trade payables account (liability) is credited.
借方记录资产和费用的增加，贷方记录负债、资本和收入的增加。例如，企业赊购存货时，存货账户（资产）记借方，应付账款账户（负债）记贷方。
Understanding this principle is essential for posting ledger entries and preparing a trial balance. Students should practise identifying the dual effect of common transactions such as cash sales, payment of expenses and drawings by the owner.
理解这一原则对于编制分类账户和试算平衡表至关重要。学生应多加练习，识别常见交易（如现金销售、支付费用、所有者提款）的双重影响。
2. The Trial Balance | 试算平衡表
A trial balance is a list of all ledger account balances at a particular date. Its main purpose is to check the arithmetical accuracy of the double-entry system. If total debits equal total credits, the ledger is said to be “in balance”.
试算平衡表是某一日期所有分类账户余额的清单，主要用于检查复式记账系统的算术准确性。如果借方总额等于贷方总额，则总分类账被视为“平衡”。
However, a balanced trial balance does not guarantee that errors are absent. Errors of omission, commission, principle, compensating errors, complete reversal of entries and original entry errors can still occur without affecting the trial balance totals.
然而，试算平衡表平衡并不能保证没有错误。遗漏错误、记账科目错误、原则性错误、抵销错误、反向记账错误以及原始分录错误都可能在不影响合计数的情况下存在，无法被直接发现。
A trial balance is therefore a useful checkpoint, but not proof of complete accuracy. It is the starting point for making end-of-period adjustments and preparing the financial statements.
因此，试算平衡表是一个有用的核对工具，但并非完全准确的证明。它是进行期末调整和编制财务报表的起点。
3. Adjustments: Accruals and Prepayments | 调整：应计与预付
To apply the accruals concept, adjustments must be made for expenses and income that relate to the current period but have not yet been settled in cash. Accrued expenses are amounts owed for services used but not yet paid. Prepaid expenses are amounts paid in advance for future benefits.
为遵循权责发生制，必须对与当期相关但尚未现金结算的费用和收入进行调整。应计费用是指已耗用但尚未支付的欠款。预付费用是指为未来利益提前支付的款项。
The adjusting entry for an accrued expense debits the relevant expense account and credits an accruals (liability) account. For a prepayment, the expense account is credited (reduced) and a prepayment (asset) account is debited. The same logic applies to accrued income and prepaid income on the revenue side.
应计费用的调整分录是借计相关费用账户、贷计应计（负债）账户。对于预付费用，则贷记费用账户（减少）并借记预付（资产）账户。同样的逻辑也适用于收入方面的应计收益和预收收益。
These adjustments directly affect both the income statement and the statement of financial position. For example, failing to accrue an expense overstates profit and understates liabilities.
这些调整直接影响利润表和财务状况表。例如，若未对应计费用作出调整，就会高估利润、低估负债。
4. Depreciation Accounting | 折旧会计
Non-current assets (except land) lose value over time due to wear and tear, obsolescence or the passage of time. Depreciation allocates the cost of the asset over its useful economic life, matching the expense against the revenue it helps generate.
除土地外的非流动资产会因磨损、过时或时间推移而逐渐丧失价值。折旧将资产成本在其经济使用寿命内分配，使费用与资产帮助创造的收入相匹配。
Straight-line: Depreciation per year = (Cost – Residual Value) / Useful Life
直线法：每年折旧额 = (成本 – 残值) / 使用年限
The reducing balance method applies a fixed percentage to the net book value (cost less accumulated depreciation) each year. This results in a higher charge in the earlier years.
余额递减法则对账面净值（成本减累计折旧）应用固定百分比，导致前期折旧额较高。
| Method 方法 | Depreciation recording 折旧记录 | Carrying amount 账面金额 |
|---|---|---|
| Straight-line 直线法 | Dr Depreciation Expense, Cr Accumulated Depreciation | Cost – Accumulated Depreciation |
| Reducing balance 余额递减法 | Dr Depreciation Expense, Cr Accumulated Depreciation | Net Book Value × % |
When an asset is sold, any profit or loss on disposal is calculated as the difference between the sale proceeds and the carrying amount at the date of sale.
当资产被出售时，处置损益为销售收入与出售日账面金额之差。
5. Bad Debts and Allowance for Doubtful Debts | 坏账与呆账准备
When a trade receivable is considered irrecoverable, it is written off as a bad debt: debit Bad Debts Expense, credit Trade Receivables. This immediately reduces profit and removes the asset from the statement of financial position.
当某一应收账款被认为无法收回时，应将其作为坏账核销：借记坏账费用，贷记应收账款。这会立即减少利润，并将该资产从财务状况表中移除。
An allowance for doubtful debts is an estimate of amounts that may not be collected in the future. The allowance is adjusted each year: an increase is an additional expense, while a decrease reduces the expense. The allowance appears as a deduction from trade receivables on the statement of financial position.
呆账准备是对未来可能无法收回金额的估计。准备金每年进行调整：增加额作为额外费用，减少额则降低费用。在财务状况表中，呆账准备列为应收账款的减项。
Students must carefully distinguish between writing off a specific bad debt and adjusting the allowance. Both affect the income statement, but only the allowance creates a valuation adjustment.
学生必须仔细区分核销某一具体坏账与调整呆账准备。两者均影响利润表，但只有呆账准备会形成估值调整。
6. Inventory and Valuation Methods | 存货与存货计价方法
Inventory is valued at the lower of cost and net realisable value (NRV). When identical items are purchased at different prices, cost must be determined using an acceptable flow assumption such as first-in, first-out (FIFO) or weighted average cost (AVCO).
存货按成本与可变现净值孰低法计价。当同种商品以不同价格购入时，必须采用可接受的成本流转假设来确定成本，例如先进先出法（FIFO）或加权平均成本法（AVCO）。
Under FIFO, the earliest purchases are assumed to be sold first, leaving the most recent costs in closing inventory. Under AVCO, a new average cost is calculated after each purchase. In times of rising prices, FIFO gives a higher closing inventory valuation and higher reported profit compared to AVCO.
在先进先出法下，假定最早购入的存货先被售出，期末存货保留的是最近的采购成本。在加权平均法下，每次购入后重新计算平均单位成本。在价格上涨时期，与加权平均法相比，FIFO会形成更高的期末存货价值和报告利润。
The choice of method affects the gross profit, net profit and the total assets figure. SQA questions often ask candidates to calculate closing inventory and cost of sales using both methods and to explain the impact on profit.
计价方法的选择会影响毛利、净利润和资产总额。SQA 考题经常要求考生同时使用两种方法计算期末存货和销售成本，并解释对利润的影响。
7. Preparation of Financial Statements | 财务报表编制
The income statement (profit and loss account) shows the profit generated over a period. A standard layout begins with sales revenue, less cost of sales (opening inventory + purchases – closing inventory) to arrive at gross profit. Operating expenses, adjusted for accruals and prepayments, together with depreciation and bad debts, are then deducted to calculate profit for the year.
利润表反映一定期间的经营成果。标准格式以销售收入为起点，减去销售成本（期初存货 + 采购 – 期末存货）得出毛利。再将经过应计和预付调整后的经营费用，连同折旧和坏账一并扣除，计算出年度净利润。
The statement of financial position (balance sheet) lists the assets, liabilities and equity at the year-end. Non-current assets are shown at carrying amount, current assets include inventory, trade receivables (net of allowance) and cash, while current liabilities include accruals and trade payables. The capital section incorporates opening capital, capital introduced, profit and drawings.
财务状况表列示了年末的资产、负债和权益。非流动资产按账面金额列示，流动资产包括存货、应收账款（扣除准备金）和现金，流动负债包括应计费用和应付账款。资本部分涵盖了期初资本、新增资本、利润和提款。
A complete set of financial statements brings together all the adjustments covered earlier. Good practice involves preparing an extended trial balance to ensure all balances are correctly transferred.
一套完整的财务报表汇集了之前涉及的所有调整。良好的训练包括编制扩展式试算平衡表，以确保所有余额都已正确结转。
8. Ratio Analysis | 比率分析
Ratio analysis evaluates the performance and financial health of a business. Profitability ratios measure how successfully the business generates returns from sales and capital.
比率分析用于评估企业的业绩和财务健康状况。盈利能力比率衡量企业从销售和资本中创造回报的能力。
Gross Profit Margin = (Gross Profit / Sales Revenue) × 100%
毛利率 = (毛利 / 销售收入) × 100%
Return on Capital Employed (ROCE) = (Profit from Operations / Capital Employed) × 100%
资本运用回报率 (ROCE) = (营业利润 / 运用资本) × 100%
Liquidity ratios assess the short-term ability to meet obligations. The current ratio compares current assets to current liabilities, while the quick (acid test) ratio excludes inventory from current assets.
流动性比率评估企业的短期偿债能力。流动比率将流动资产与流动负债进行比较，速动比率则从流动资产中剔除存货（酸性测试比率）。
Quick Ratio = (Current Assets – Inventory) / Current Liabilities : 1
速动比率 = (流动资产 – 存货) / 流动负债 : 1
Efficiency ratios, such as inventory turnover (times or days) and trade receivables collection period, reveal how well resources are managed. For instance, a lengthening collection period may signal credit control problems.
效率比率例如存货周转率（次数或天数）和应收账款回收期，揭示了资源管理的效率。例如，回收期延长可能暗示信用控制存在问题。
9. Budgeting | 预算编制
A budget is a quantitative plan of action that aids planning, coordination and control. Cash budgets are particularly important, forecasting cash inflows and outflows to determine the expected closing cash balance each month.
预算是量化的行动计划，有助于规划、协调与控制。现金预算尤为重要，它预测现金流入和流出，以确定每月预期的期末现金余额。
Items such as cash sales, receipts from trade receivables, purchases, wages and other payments are listed to compute the net cash flow. An overdrawn balance is shown as a negative or in brackets. A simple cash budget helps managers anticipate shortfalls and arrange finance in advance.
在现金预算中，逐项列出诸如现金销售、应收账款收款、采购、工资及其他支出，以计算净现金流量。透支余额以负数或括号表示。一份简单的现金预算能帮助管理层预见资金短缺并预先安排融资。
Budgets are often prepared for selling and administration expenses or production activities, and they are compared with actual results to identify variances. Variance analysis supports corrective action and performance evaluation.
预算通常也会为销售及管理费用或生产活动而编制，并与实际结果进行比较以识别差异。差异分析有助于采取纠正措施并评估业绩。
10. Incomplete Records | 不完全记录
Many small businesses do not maintain full double-entry records. In such cases profit must be calculated using the accounting equation by comparing the change in net assets over the period, adjusted for drawings and capital introduced.
许多小型企业没有完整的复式记账记录。在此情况下，必须利用会计等式计算利润，即比较期间内净资产的变化，并针对提款和资本投入进行调整。
Profit = Closing Capital – Opening Capital + Drawings – Capital Introduced
利润 = 期末资本 – 期初资本 + 提款 – 资本投入
A statement of affairs is prepared to determine the net assets (capital) at the start and end of the period. It lists assets at estimated values and deducts all liabilities. The missing figure from incomplete records can also be found using mark-up or margin percentages, as well as through a cash summary that reconciles bank movements.
编制财务状况说明书（净资产表）以确定期初和期末的净资产（资本）。该表按估计价值列示资产并减去所有负债。不完全记录中的丢失数据也可以借助成本加成率或毛利率，以及通过核对银行资金变动的现金汇总表找到。
Questions on incomplete records integrate many core skills and require careful working. Practising the reconstruction of sales and purchases control accounts is a powerful way to prepare for these scenarios.
关于不完全记录的考题综合了多种核心技能，需要细致的运算。练习重建销售和购货控制账户是应对这类考题的有效方法。
