Each section provides bilingual explanations to reinforce key ideas and support revision for the CIE Pre-U examinations.
剑桥大学预科会计课程（9765）要求深入学习财务会计、成本与管理会计以及财务管理知识。本文梳理了每位考生必须掌握的核心知识点，从基本会计概念到投资评估方法，逐一讲解。每个部分均提供中英双语解释，以强化关键概念，助力 CIE Pre-U 考试复习。
1. Accounting Concepts and Principles | 会计概念与原则
The foundation of all accounting practice rests on core concepts such as going concern, accruals (or matching), consistency, prudence, materiality, and the business entity concept. The going concern assumption implies that a business will continue operating for the foreseeable future, justifying the valuation of assets at historical cost less depreciation rather than break-up values. The accruals concept requires that revenues and expenses be recognised when earned or incurred, not when cash is received or paid. Consistency demands that accounting treatments remain unchanged from one period to the next to allow meaningful comparison, while prudence ensures that liabilities and losses are provided for as soon as they are foreseen, but profits are only recognised when realised.
所有会计实务的基础建立在一系列核心概念之上，包括持续经营、权责发生制（配比原则）、一致性、稳健性、重要性和企业主体概念。持续经营假设意味着企业将在可预见的未来继续经营，因此资产按历史成本减折旧计价，而非按清算价值。权责发生制要求收入和费用在赚取或发生时确认，而不是在现金收付时。一致性保证各期会计处理方法不变，以便进行有意义的比较；稳健性则要求预见到负债和损失时立即计提，但利润只在实现时才确认。
s = Liabilities + Equity. The money measurement concept limits accounting records to transactions that can be expressed in monetary terms. The historical cost convention states that assets are initially recorded at their purchase price. The realisation concept links revenue recognition to the point at which goods or services are delivered and the customer assumes significant risks and rewards of ownership.
其他关键概念还包括复式记账原理（双重影响），确保每笔交易都影响两个账户，保持会计等式：资产 = 负债 + 权益。货币计量概念将会计记录限制在能以货币计量的交易上。历史成本惯例规定资产最初按购买价格记录。实现概念则将收入确认与商品或服务交付、客户承担重大风险和报酬的时间点挂钩。
2. Double Entry Bookkeeping | 复式记账
Double entry is the mechanism through which every financial transaction is recorded in at least two ledger accounts — one debited and one credited. The total debits must always equal the total credits. Assets, expenses, and drawings are increased by debits and decreased by credits. Liabilities, capital, and revenue are increased by credits and decreased by debits. This system maintains the integrity of the accounting equation and facilitates the preparation of a trial balance, which lists all ledger balances to check for arithmetic accuracy.
复式记账是将每一笔财务交易至少记录到两个分类账户的机制——一个借记，一个贷记。借方总额必须始终等于贷方总额。资产、费用和提款增加记借方，减少记贷方。负债、资本和收入增加记贷方，减少记借方。这一系统维护了会计等式的完整性，并有助于编制试算平衡表，该表列出所有账户余额以检查算术准确性。
If a trial balance fails to balance, common errors include omission, commission, principle, compensating errors, and transposition errors. A suspense account is opened to record the difference temporarily while the error is investigated. Once identified, correcting journal entries with proper narrations are posted. Students must also be able to distinguish between errors that affect the trial balance and those that do not, such as complete reversal of entries.
如果试算表不平衡，常见错误包括遗漏、错记账户、原则性错误、抵销错误和换位错误。在查明差错时，会开设暂记账户暂时记录差额。一旦查明，就要编制带有恰当说明的更正分录。考生还须能够区分影响试算表平衡的错误和不影响平衡的错误，例如完全颠倒分录。
3. Financial Statements for Sole Traders | 个体经营者财务报表
The income statement (or statement of profit or loss) for a sole trader shows revenue less cost of sales to derive gross profit, then deducts operating expenses to arrive at profit for the year. Cost of sales is calculated as opening inventory plus purchases less closing inventory. The statement of financial position presents assets (non‑current and current), liabilities (current and non‑current), and capital (opening capital plus profit less drawings). Adjustments for accruals, prepayments, depreciation, and irrecoverable debts are essential to ensure figures reflect the true financial position.
个体经营者的利润表（损益表）反映收入减去销售成本得到毛利，再减去营业费用得出年度利润。销售成本的计算公式为：期初存货加本期购货减期末存货。财务状况表列示资产（非流动资产和流动资产）、负债（流动负债和非流动负债）以及资本（期初资本加利润减提款）。对应计费用、预付款项、折旧和坏账进行调整，对于确保数字反映真实财务状况至关重要。
Depreciation methods include straight‑line and reducing balance. Straight‑line depreciation spreads the cost evenly over useful life, while reducing balance applies a constant percentage to the net book value. Disclosure of non‑current assets at cost, accumulated depreciation, and carrying amount is required. The financial statements must also comply with the appropriate format prescribed by international accounting standards for sole traders.
折旧方法包括直线法和余额递减法。直线法在资产使用寿命内均匀分摊成本，余额递减法则将固定百分比应用于账面净值。非流动资产须披露原值、累计折旧和账面价值。财务报表还须遵循国际会计准则为个体经营者规定的适当格式。
4. Partnership Accounts | 合伙企业会计
Partnerships introduce a more complex capital structure and profit‑sharing arrangements. The appropriation account starts with the profit for the year, then adds interest on drawings and deducts interest on capital and partners’ salaries to arrive at residual profit, which is shared in the profit‑sharing ratio. Each partner maintains a capital account (usually fixed) and a current account where share of profit, drawings, and interest are recorded. Goodwill, when a new partner is admitted or a partner retires, must be valued and adjusted through partners’ capital accounts.
合伙企业引入了更复杂的资本结构和利润分配安排。利润分配账户从年度利润开始，加上提款利息，减去资本利息和合伙人薪酬，得到剩余利润，再按利润分配比例分享。每位合伙人保持一个资本账户（通常为固定）和一个往来账户，记录利润份额、提款和利息。当新合伙人入伙或原有合伙人退伙时，商誉必须估值并通过合伙人资本账户进行调整。
On dissolution, the business ceases and assets are realised. The proceeds are used to pay external liabilities, then partners’ loan accounts, and finally partners’ capital balances. Any deficit on a partner’s capital account must be covered by that partner personally, following the rule in Garner vs Murray if applicable. The partnership statement of financial position shows capital and current accounts separately and must clearly disclose the appropriation of profit.
散伙时，企业停止经营，资产变现。变价收入首先用于清偿外部负债，然后偿还合伙人借款账户，最后归还合伙人资本余额。合伙人资本账户出现亏空时，须由该合伙人个人弥补，必要时遵循 Garner v Murray 案规则。合伙企业财务状况表单独列示资本和往来账户，并须清晰披露利润分配情况。
5. Limited Company Accounts | 公司账目
Limited companies issue shares to raise equity finance. The statement of changes in equity shows share capital (ordinary and preference), share premium, retained earnings, and other reserves. The income statement for a company is similar to that of a sole trader but includes items such as directors’ remuneration, debenture interest, and taxation. The statement of financial position distinguishes between equity and non‑current liabilities, with share capital and reserves shown under total equity.
有限公司通过发行股份筹集资本。权益变动表列示股本（普通股和优先股）、股本溢价、留存收益和其他准备金。公司利润表与独资企业类似，但包含董事薪酬、债券利息和税费等项目。财务状况表区分权益和非流动负债，股本和准备金列示在权益总额项下。
Companies must also account for the issue of shares at par or at a premium, bonus issues, and rights issues. Dividends — interim and final — are disclosed in the notes or in the statement of changes in equity. A key requirement is the preparation of the income statement, statement of financial position, and statement of changes in equity in accordance with IAS 1 Presentation of Financial Statements, ensuring comparative figures are shown.
公司还须核算按面值或溢价发行股票、红股发行以及配股等事项。中期和末期股利在附注或权益变动表中披露。关键要求是按照《国际会计准则第1号——财务报表列报》编制利润表、财务状况表和权益变动表，并确保列示可比数字。
6. Statement of Cash Flows | 现金流量表
The statement of cash flows analyses cash inflows and outflows under three headings: operating activities, investing activities, and financing activities. The indirect method adjusts profit before tax for non‑cash items (depreciation, profit/loss on disposal), changes in working capital, and interest or tax paid to derive net cash from operating activities. Investing activities include purchase and sale of non‑current assets and investment income received. Financing activities cover proceeds from share issues, loans taken or repaid, and dividends paid.
现金流量表将现金流入和流出分为三个类别：经营活动、投资活动和融资活动。间接法对税前利润进行调整，剔除非现金项目（折旧、处置损益）、营运资本变动以及支付利息与税费，以得出经营活动现金净流量。投资活动包括买卖非流动资产和收到的投资收益。融资活动包括发行股份收入、借入或偿还贷款以及支付股息。
The direct method lists cash receipts from customers and cash payments to suppliers and employees, but the CIE Pre-U syllabus focuses on the indirect method. Reconciling profit from operations to net cash flow is a critical skill. The statement must also reconcile the opening and closing cash and cash equivalents, which typically comprise cash, bank, and short‑term highly liquid investments.
直接法列示从顾客收取的现金及对供应商和员工的现金支付，但 CIE Pre-U 大纲以间接法为主。将经营利润调节为净现金流量是一项关键技能。报表还须将期初与期末的现金和现金等价物调节一致，现金等价物通常包括库存现金、银行存款和短期高流动性投资。
7. Incomplete Records | 不完整记录
Many small businesses do not keep full double‑entry records. To prepare financial statements, the accountant must reconstruct missing figures using control accounts, markup/margin calculations, and the comparison of opening and closing net assets. The statement of affairs at the beginning and end of the period is used to determine profit by comparing the change in net assets, adjusting for drawings and capital introduced. Known as the single‑entry or ‘capital comparison’ method, it provides a starting point for deriving sales, purchases, and expenses.
许多小型企业不保留完整的复式记录。为编制财务报表，会计师必须利用控制账户、加成率/毛利率计算以及期初期末净资产比较来重建缺失的数据。编制期初和期末财务状况表，通过比较净资产变动，并调整提款和投入资本，来确定利润。这种方法被称为单式记账或“资本比较法”，是推导销售收入、采购和费用的起点。
To find credit sales, a total receivables account is constructed, using receipts from customers and opening and closing receivables. Similarly, a total payables account reveals credit purchases. The use of rates of gross profit (margin on sales or markup on cost) helps to estimate inventory, sales, or purchases when one component is missing. Accurate completion of these control accounts is central to producing reliable final accounts from incomplete records.
为求得赊销金额，需要编制应收账款总账，利用从顾客收取的现金以及期初期末应收款余额。类似地，应付账款总账揭示赊购金额。当某一要素缺失时，运用毛利率（销售毛利率或成本加成率）可估算存货、销售收入或采购额。准确完成这些控制账户是利用不完整记录编制可靠年终报表的核心。
8. Accounting for Clubs and Societies | 俱乐部和社团会计
Non‑trading organisations such as clubs and societies prepare a receipts and payments account and an income and expenditure account instead of a traditional income statement. The receipts and payments account is a summary of the cash book, while the income and expenditure account follows accruals principles to show the surplus or deficit for the period. The accumulated fund replaces capital and is calculated as the difference between assets and liabilities at the start of the period.
非营利组织（如俱乐部和社团）编制收支表以及收入与支出账户，而非传统的利润表。收支表是现金出纳簿的汇总；收入与支出账户则遵循权责发生制，反映当期盈余或亏损。累积基金取代资本，按其期初资产与负债的差额计算得出。
Bar trading accounts are often prepared to ascertain profit or loss from the members’ bar, incorporating purchases, sales, and inventory. Subscriptions in advance or in arrears must be adjusted to reflect the income attributable to the period. Donations, life membership fees, and specific fund accounts (e.g. building fund) are common and require correct classification as income or capital. The statement of financial position presents the club’s assets, liabilities, and accumulated fund.
通常要编制酒吧经营账户，以确定会员酒吧的盈亏，其中包含采购、销售和存货。预收或应收的会费必须调整，以反映当期应计的收入。捐赠、终身会费和特定基金账户（如建设基金）很常见，需要正确划分为收入或资本。财务状况表列示俱乐部的资产、负债和累积基金。
9. Manufacturing Accounts | 制造业账目
A manufacturing account is added to the income statement to calculate the cost of goods produced. Direct costs — direct materials, direct labour, direct expenses — are combined to give prime cost. Factory overheads (indirect manufacturing costs) are then added, and adjustments for opening and closing work in progress give factory cost of production. This production cost is transferred to the trading account, replacing conventional purchases for a manufacturing business.
制造业企业需在利润表中增加制造成本表，以计算完工产品成本。直接成本——直接材料、直接人工、直接费用——汇总为基本成本。再加上工厂间接费用（间接制造成本），并对期初和期末在产品进行调整，得出工厂生产成本。该生产成本转入销售成本账户，取代制造企业的一般采购。
If the business transfers goods to the trading account at market value instead of cost, a provision for unrealised profit (PUP) must be created to remove the profit element from closing inventory. The manufacturing account allows the separation of production costs from administrative, selling, and distribution costs, enhancing management control over factory efficiency and gross profit analysis.
如果企业将商品以市价而非成本转入销售账户，则必须计提未实现利润准备，以从期末存货中剔除利润成分。制造账户使得生产成本与行政、销售和配送费用得以区分开来，从而加强管理层对生产效率的控制和毛利分析。
10. Cost Accounting: Job, Batch and Process Costing | 成本会计：分步、分批和分步法
Job costing assigns costs to specific customer orders. Direct materials, direct labour, and direct expenses are traced to each job, while overheads are absorbed using a predetermined overhead absorption rate (OAR), usually based on direct labour hours or machine hours. Over‑ or under‑absorption of overheads is adjusted at the period end. Batch costing is similar, but costs are accumulated for a batch of identical units divided by the number of units to find unit cost.
订单成本法将成本分配至具体的客户订单。直接材料、直接人工和直接费用追溯到每个订单，而间接费用则使用预定的间接费用吸收率吸收，通常以直接人工小时或机器小时为基础。期末再调整多吸收或少吸收的间接费用。分批成本法类似，但成本按一批同质产品汇总后除以数量求得单位成本。
Process costing is used where production is continuous. Costs are averaged over all units produced, accounting for work in progress using equivalent units. The weighted average or FIFO method is applied to value completed output and closing WIP. Normal loss, abnormal loss, and abnormal gain with their scrap values are critical elements of process accounts. By‑products and joint products may require apportionment of joint costs using sales value at split‑off point or net realisable value.
分步成本法适用于连续生产。成本平均分摊到所有产量上，并使用约当产量核算在产品。加权平均法或先进先出法用于对完工产量和期末在产品计价。正常损失、非正常损失以及非正常收益及其残值是分步账户的关键组成部分。联产品和副产品可能需要按分离点销售价值或可变现净值分摊联合成本。
11. Budgeting and Budgetary Control | 预算编制与控制
Budgeting is a planning and control tool. Sales, production, materials, labour, overhead, and cash budgets are prepared on a functional basis. A master budget consolidates them into budgeted income statement and statement of financial position. Cash budgets are especially useful for highlighting future surpluses or deficits, enabling proactive treasury management. The preparation of a cash budget requires careful scheduling of receipts from receivables and payments to creditors, along with capital and revenue expenditures.
预算是一项计划与控制工具。销售、生产、材料、人工、间接费用和现金预算按职能编制。总预算将它们汇总为预算利润表和财务状况表。现金预算尤其有助于突显未来盈余或赤字，便于主动进行资金管理。编制现金预算需要细致地安排应收账款回收和应付账款支付的时间，以及资本支出和收益性支出。
Budgetary control compares actual results with flexed budgets to evaluate performance. A flexible budget adjusts for actual activity levels, providing more meaningful variances than a fixed budget. Variances are analysed into expenditure and volume variances. Managers use this analysis to implement corrective actions and improve efficiency. Participative budgeting can improve motivation but may introduce budgetary slack.
预算控制将实际结果与弹性预算进行比较，以评估业绩。弹性预算根据实际业务量水平进行调整，相较于固定预算能提供更有意义的差异数据。差异被分解为开支差异和业务量差异。管理层利用此分析采取纠正措施并提高效率。参与式预算可以提升积极性，但可能引入预算松弛。
12. Standard Costing and Variance Analysis | 标准成本和差异分析
Standard costing predetermines unit costs for materials, labour, and overheads. Variance analysis identifies and quantifies differences between standard and actual costs. Material variances include material price variance (MPV) and material usage variance (MUV). Labour variances include labour rate and labour efficiency variances. Variable overhead variances similarly split into expenditure and efficiency. Fixed overhead variances include expenditure and volume variances (volume further subdivided into capacity and efficiency).
标准成本法事先确定材料、人工和间接费用的单位成本。差异分析识别并量化标准成本与实际成本之间的差异。材料差异包括材料价格差异和材料用量差异。人工差异包括工资率差异和人工效率差异。变动制造费用差异类似地分为支出差异和效率差异。固定制造费用差异包含支出差异和业务量差异（业务量差异再分为生产能力差异和效率差异）。
The basic formulas are as follows:
MPV = (Standard Price − Actual Price) × Actual Quantity Purchased
材料价格差异 = (标准价格 - 实际价格) × 实际采购量
MUV = (Standard Quantity for Actual Output − Actual Quantity Used) × Standard Price
材料用量差异 = (实际产量的标准用量 - 实际用量) × 标准价格
Sales variances — sales price and sales volume — may also be calculated. When reconciling budgeted profit with actual profit, variances are aggregated and presented in an operating statement. An adverse variance reduces profit while a favourable variance increases it. Understanding the interrelationships and the ability to suggest plausible causes for variances is a frequently examined skill.
也可能计算销售差异——销售价格差异和销售数量差异。在将预算利润与实际利润进行调节时，差异会汇总在一张经营报表中。不利差异减少利润，有利差异增加利润。理解差异之间的相互关系并能提出可能的差异成因，是经常被考查的能力。
13. Investment Appraisal | 投资评估
Investment appraisal techniques assist in evaluating long‑term capital projects. Payback period measures the time required to recover the initial investment from net cash inflows. Accounting rate of return (ARR) compares average annual accounting profit to average investment or initial investment. Net present value (NPV) discounts future cash flows to their present value using a chosen cost of capital, and a project is acceptable if NPV > 0.
投资评估方法有助于评价长期资本项目。投资回收期衡量从净现金流入中收回初始投资所需的时间。会计收益率将平均年度会计利润与平均投资额或初始投资额进行比较。净现值法使用选定的资本成本将未来现金流量折现，若 NPV > 0，则项目可接受。
NPV = Σ [CFₜ ÷ (1 + r)ᵗ] − I₀
净现值 = 现金流量（CFₜ）按折现率 r 折现之和减去初始投资 I₀
Internal rate of return (IRR) is the discount rate that makes NPV equal to zero. It is found by interpolation using two NPV calculations. Projects are ranked by NPV or IRR, but NPV is theoretically superior as it maximises shareholder wealth and avoids scale and timing issues. Sensitivity analysis and consideration of non‑financial factors are also essential for a complete evaluation.
内含报酬率是使 NPV 等于零的折现率，通常通过两个 NPV 计算值插值求得。项目依据 NPV 或 IRR 排序，但 NPV 理论上更优，因为它最大化股东财富，并能避免规模和早晚差异问题。敏感性分析和考虑非财务因素对于全面评估同样必不可少。
