📚 Year 12 CAIE Accounting: Core Knowledge Review | Year 12 CAIE 会计：核心知识点梳理

Mastering the fundamentals of accounting in Year 12 is essential for success in the CAIE syllabus. This article revisits the core knowledge areas every student must command, from the accounting equation and double entry to financial statements and ratio analysis.

掌握 Year 12 会计基础知识对在 CAIE 考试中取得成功至关重要。本文重温每位学生都必须掌握的核心知识领域，从会计等式与复式记账，到财务报表和比率分析。

1. The Accounting Equation and Core Principles | 会计等式与核心原则

The accounting equation – Assets = Liabilities + Equity – is the cornerstone of all bookkeeping. Every transaction affects at least two elements of the equation, ensuring it always balances.

会计等式——资产 = 负债 + 所有者权益——是所有簿记的基石。每笔交易至少影响等式的两个要素，确保其始终保持平衡。

Students must also grasp fundamental accounting concepts that underpin the preparation of financial statements:

学生还必须掌握支撑财务报表编制的基本会计概念：

• Going concern / 持续经营: assumes the business will continue to operate for the foreseeable future / 假设企业在可预见的未来将持续经营。
• Accruals / 权责发生制: revenue and expenses are recorded when earned or incurred, not when cash is received or paid / 收入和费用在赚取或发生时记录，而非在现金收支时记录。
• Consistency / 一致性: the same accounting treatment is applied to similar items from one period to the next / 相似的交易在不同期间应采用相同的会计处理方法。
• Prudence / 谨慎性: profits are not anticipated, but all foreseeable losses are provided for / 不预计利润，但为所有可预见的损失计提准备。
• Materiality / 重要性: information is material if its omission or misstatement could influence users’ decisions / 如果遗漏或错报可能影响使用者的决策，该信息即具有重要性。

2. Double-Entry Bookkeeping and Ledger Accounts | 复式记账与分类账

Double-entry bookkeeping requires every debit to have a corresponding credit. The rules for asset, liability, capital, income, and expense accounts must be committed to memory: assets increase with a debit, liabilities and capital increase with a credit, income increases with a credit, and expenses increase with a debit.

复式记账要求每一笔借方记录都有对应的贷方记录。资产、负债、资本、收入和费用账户的增减规则必须牢记：资产增加记借方，负债和资本增加记贷方，收入增加记贷方，费用增加记借方。

Ledger accounts are presented in T-account format, with the debit side on the left and the credit side on the right. Each entry shows the date, the name of the opposite account, and the amount. Balancing off accounts at the end of a period reveals the closing balance to be carried down.

分类账以 T 型账户形式呈现，左边为借方，右边为贷方。每笔分录需列明日期、对应账户名称和金额。期末结平账户可得出需结转至下一个会计期的结账余额。

3. Books of Prime Entry and the Journal | 原始账簿与日记账

Transactions are first recorded in books of prime entry before being posted to the ledger. The main books are: sales day book, purchases day book, sales returns day book, purchases returns day book, cash book (two-column and three-column), and the petty cash book.

交易首先在原始账簿中记录，然后过账到分类账。主要的原始账簿包括：销售日记账、购货日记账、销售退回日记账、购货退回日记账、现金簿（两栏和三栏式）以及小额现金簿。

The general journal is used for non-routine transactions, such as the purchase of a non-current asset on credit, correction of errors, opening entries, and recording depreciation. Every journal entry includes a narrative explaining the transaction.

普通日记账用于记录非常规交易，比如赊购非流动资产、更正错误、开账分录和记录折旧。每笔日记账分录都包含叙述，对交易加以说明。

4. The Trial Balance | 试算平衡表

A trial balance lists all the balances from the general ledger at a specific date, with debit balances in one column and credit balances in another. The total of the debit column must equal the total of the credit column if the double entry is arithmetically accurate.

试算平衡表在某一特定日期列示总分类账的所有余额，借方余额和贷方余额分别列示。如果记账在算术上正确无误，借方栏合计必须等于贷方栏合计。

However, a balanced trial balance does not prove that no errors have occurred. Errors such as omission, commission, principle, original entry, complete reversal, and compensating errors may still exist. Year 12 students must be able to identify and correct errors using a suspense account when necessary.

然而，试算平衡表平衡并不能证明没有错误发生。遗漏错误、账户错误、原则性错误、原始记录错误、完全颠倒错误和抵销性错误仍可能存在。Year 12 学生必须能够识别错误，并在必要时通过暂记账户进行更正。

5. Accruals and Prepayments | 应计项目与预付款项

Adjusting for accruals and prepayments is essential to apply the accruals concept. An accrued expense is an expense incurred but not yet paid; it is added to the expense in the income statement and shown as a current liability in the balance sheet.

对应计项目和预付款项进行调整是运用权责发生制概念的必要环节。应计费用是指已经发生但尚未支付的费用；在利润表中加到相关费用项下，并在资产负债表中列为流动负债。

A prepaid expense is an expense paid in advance; the unexpired portion is deducted from the expense in the income statement and shown as a current asset. Accrued income and prepaid income are treated similarly, with the matching principle guiding all adjustments.

预付款项是提前支付的费用；其中未到期的部分在利润表中从费用中扣减，并列为流动资产。应计收入和预收收入的处理类似，所有调整均依据配比原则进行。

Adjusted expense = paid amount + closing accrual – opening accrual – closing prepayment + opening prepayment

调整后费用 = 已付金额 + 期末应计 – 期初应计 – 期末预付 + 期初预付

6. Bad Debts and Allowance for Doubtful Debts | 坏账与坏账准备

A bad debt is a trade receivable that is considered irrecoverable and is written off. The double entry is to debit the bad debts expense account and credit the trade receivables account. If a previously written-off debt is later recovered, the recovered amount is treated as income.

坏账是指被认为无法收回、需予以核销的应收账款。会计分录为借记坏账费用账户，贷记应收账款账户。如果之前已核销的坏账之后又收回，则收回的金额应作为收入处理。

An allowance for doubtful debts is an estimate of the amount of receivables that may not be collected. The movement in the allowance (increase or decrease) is recognised in the income statement as an expense or as a reduction in expense. The closing allowance is deducted from trade receivables in the balance sheet.

坏账准备是对可能无法收回的应收账款金额的估计。准备的变动（增加或减少）在利润表中确认为费用或费用的减少。期末准备在资产负债表中从应收账款中扣减。

Increase in allowance	Dr Bad debts expense, Cr Allowance for doubtful debts
Decrease in allowance	Dr Allowance for doubtful debts, Cr Bad debts expense (or income)

坏账准备增加：借记坏账费用，贷记坏账准备。
坏账准备减少：借记坏账准备，贷记坏账费用（或收入）。

7. Depreciation of Non-Current Assets | 非流动资产折旧

Depreciation is the systematic allocation of the cost of a non-current asset over its useful life. It ensures that the income statement reflects the cost of using the asset and that the balance sheet shows a realistic carrying amount.

折旧是将非流动资产成本在其使用寿命内进行系统分配。它确保利润表反映资产的使用成本，并使资产负债表显示符合实际的账面净值。

Year 12 students must apply two main methods:

Year 12 学生必须能够应用两种主要方法：

Straight-line method: (Cost – Residual value) ÷ Useful life

直线法：（成本 – 残值）÷ 使用寿命

Reducing balance method: Net book value × rate of depreciation

余额递减法：账面净值 × 折旧率

The accounting entries for depreciation are to debit the depreciation expense account and credit the accumulated provision for depreciation account. When a non-current asset is sold, a disposal account is used to calculate profit or loss on disposal.

折旧的会计分录为借记折旧费用账户，贷记累计折旧账户。当出售非流动资产时，需要使用处置账户来计算处置损益。

8. Inventory Valuation | 存货计价

Inventory must be valued at the lower of cost and net realisable value (NRV). Cost typically includes the purchase price, import duties, transport, and handling costs. NRV is the estimated selling price less any costs necessary to complete and sell the item.

存货必须按成本与可变现净值（NRV）孰低计价。成本通常包括购买价格、进口关税、运输和装卸成本。可变现净值是估计售价减去使物品达到可售状态及完成销售所需的一切费用。

For identical items purchased at different prices, students must be able to apply the first in, first out (FIFO) and average cost (AVCO) methods to determine the value of closing inventory and cost of sales. The choice of method affects reported profit and the balance sheet value of inventory.

对于以不同价格购入的同种物品，学生必须能够运用先进先出法（FIFO）和加权平均成本法（AVCO）来确定期末存货价值和销售成本。方法的选择会影响报告的利润及存货的资产负债表价值。

9. Bank Reconciliation | 银行对账

A bank reconciliation statement explains the difference between the cash book balance and the bank statement balance. Common reconciling items include unpresented cheques, uncredited deposits, bank charges, standing orders, direct debits, and errors.

银行对账表是为了解释现金簿余额与银行对账单余额之间的差异。常见的调节项目包括未兑现支票、未入账存款、银行手续费、定期付款指令、直接借记以及错误。

Students must prepare an updated cash book first, recording items that appear on the bank statement but not yet in the cash book, such as bank charges and direct debits. Then, a bank reconciliation statement is prepared, starting with the updated cash book balance and adjusting for unpresented cheques and uncredited deposits.

学生必须先编制更新后的现金簿，记录已出现在银行对账单上但尚未记入现金簿的项目，例如银行手续费和直接借记。然后编制银行对账表，从更新后的现金簿余额出发，调整未兑现支票和未入账存款。

10. Control Accounts | 控制账户

Control accounts are summary accounts in the general ledger that replicate the total of the individual accounts in the sales ledger and purchases ledger. The sales ledger control account brings together all transactions relating to trade receivables, while the purchases ledger control account does the same for trade payables.

控制账户是总分类账中的汇总账户，反映销售明细账和购货明细账中所有个别账户的合计数。销售明细账控制账户汇总所有与应收账款相关的交易，而购货明细账控制账户则汇总所有与应付账款相关的交易。

The main sources of information for control accounts are the books of prime entry: total sales from the sales day book, total purchases from the purchases day book, returns from returns day books, cash received and discounts allowed from the cash book, and so on. Control accounts help in locating errors and are used in the preparation of financial statements for incomplete records.

控制账户的主要信息来源是原始账簿：来自销售日记账的销售总额、来自购货日记账的购货总额、来自退货日记账的退货，以及来自现金簿的现金收入和折扣允许额等。控制账户有助于查找错误，并且在不完整记录用于编制财务报表时非常有用。

11. Financial Statements: Income Statement and Balance Sheet | 财务报表：利润表与资产负债表

The income statement measures the financial performance of a business over a period. It calculates gross profit (sales revenue less cost of sales) and profit for the year (gross profit plus other income less expenses). Year 12 students must prepare the statement from a trial balance, incorporating adjustments.

利润表衡量企业在一定期间内的财务业绩。它计算毛利（销售收入减销售成本）和年度利润（毛利加上其他收入再减费用）。Year 12 学生必须根据试算平衡表并融入调整项目编制利润表。

The balance sheet (statement of financial position) shows the business’s assets, liabilities, and equity at a point in time. Assets are typically classified as non-current or current. Liabilities are similarly split. The balance sheet must reflect the accounting equation: Assets = Liabilities + Equity.

资产负债表（财务状况表）列示企业在某一时点的资产、负债和所有者权益。资产通常分为非流动资产和流动资产。负债同样分为非流动和流动。资产负债表必须反映会计等式：资产 = 负债 + 所有者权益。

Key formatting requirements include the use of ‘cost’ and ‘accumulated depreciation’ columns for non-current assets, and the correct presentation of working capital (current assets minus current liabilities) in a vertical format.

关键的格式要求包括非流动资产使用“成本”和“累计折旧”栏，以及在垂直式报表中正确列示营运资本（流动资产减去流动负债）。

12. Introduction to Ratio Analysis | 比率分析入门

Ratio analysis helps stakeholders assess profitability, liquidity, efficiency, and financial structure. Year 12 students are expected to calculate and interpret a range of ratios: gross profit margin, profit margin, return on capital employed (ROCE), current ratio, liquid (acid test) ratio, and trade receivables turnover.

比率分析帮助利益相关者评估盈利能力、流动性、效率和财务结构。Year 12 学生应会计算和解释一系列比率：毛利率、净利率、资本回报率 (ROCE)、流动比率、速动比率（酸性测试比率）和应收账款周转率。

All formulas must be memorised and applied correctly:

所有公式必须熟记并正确运用：

Gross profit margin = (Gross profit ÷ Revenue) × 100%

毛利率 =（毛利 ÷ 收入）× 100%

ROCE = (Profit from operations ÷ Capital employed) × 100%

资本回报率 =（经营利润 ÷ 动用资本）× 100%

Current ratio = Current assets : Current liabilities

流动比率 = 流动资产 ：流动负债

Interpretation requires comparing ratios with previous periods, with industry averages, and with other businesses. Students should be able to suggest possible reasons for changes and recommend actions.

解释比率需要与前期、行业平均水平和其他企业进行比较。学生应能对变化提出可能的原因并建议相应措施。
