本文系统梳理了 Year 11 Eduqas 会计课程的核心概念、技术与原则。从基础的会计等式到财务报表的编制及比率分析，这些要点将帮助你巩固理解，自信地应对考试。
1. Fundamental Accounting Principles | 会计基本概念
The purpose of accounting is to record, classify and summarise financial transactions to provide useful information for decision-making. Several key concepts underpin the preparation of accounts, including the business entity concept, which treats the business as separate from its owner.
会计的目的是记录、分类和汇总财务交易，为决策提供有用信息。若干关键概念构成了账目编制的基础，其中包括企业实体概念，即将企业与其所有者视为相互独立的个体。
The going concern concept assumes that the business will continue to operate for the foreseeable future, meaning assets are valued at cost rather than forced-sale value. Consistency requires that the same accounting methods are used from one period to the next to allow meaningful comparison.
持续经营概念假定企业在可预见的未来将继续经营，这意味着资产按成本而非强制出售价值计价。一致性要求在各会计期间采用相同的会计方法，以便进行有意义的比较。
The accruals concept states that income and expenses are recorded when they are earned or incurred, not when cash is received or paid. Prudence ensures that profits are not overstated and all foreseeable losses are accounted for.
应计制概念指出，收入和费用应在其赚取或发生当期确认，而非在现金收付时确认。谨慎性确保利润不被高估，并且所有可预见的损失都被计入。
2. Double-Entry Bookkeeping | 复式记账法
Every financial transaction affects at least two accounts, following the rule that for every debit there must be an equal and opposite credit. This system ensures the accounting equation always balances and errors can be detected through the trial balance.
每一笔财务交易至少影响两个账户，遵循“有借必有贷，借贷必相等”的规则。该体系确保会计等式始终平衡，并且可以通过试算平衡表发现错误。
Debit entries increase assets and expenses, while they decrease liabilities, capital and income. Credit entries do the opposite: they increase liabilities, capital and income, and decrease assets and expenses.
借方分录增加资产和费用，同时减少负债、资本和收入。贷方分录则相反：增加负债、资本和收入，减少资产和费用。
A typical transaction, such as purchasing inventory for cash, would be recorded as a debit to the purchases account and a credit to the cash account. Purchases of non-current assets on credit involve debiting the asset account and crediting the supplier's account.
一笔典型交易，例如以现金购买存货，将记录为借记购货账户，贷记现金账户。赊购非流动资产则涉及借记资产账户，贷记供应商账户。
3. The Accounting Equation | 会计等式
The foundation of all financial statements is the accounting equation. It can be expressed in its simplest form as:
所有财务报表的基础是会计等式，其最简形式可表示为：
Assets = Liabilities + Capital
Assets represent what the business owns or controls, such as cash, inventory, equipment and trade receivables. Liabilities are what the business owes to third parties, including bank loans and trade payables.
资产代表企业拥有或控制的资源，如现金、存货、设备和应收贸易款。负债是企业欠第三方的款项，包括银行贷款和应付贸易款。
Capital represents the owner' n can be expanded to reflect income and expenses: Assets = Liabilities + Capital + (Income – Expenses).
资本代表所有者对企业的投资加上留存利润减去提款。等式可扩展以反映收入和费用：资产 = 负债 + 资本 + (收入 - 费用)。
4. Journals and Ledgers | 日记账与分类账
Transactions are first recorded in books of prime entry, also known as journals. These include the sales journal for credit sales, the purchases journal for credit purchases, the cash book for all bank and cash transactions, and the general journal for non-routine entries.
交易首先记录在原始分录簿（也称日记账）中。包括用于赊销的销售日记账、用于赊购的采购日记账、记录所有银行和现金交易的现金簿，以及用于非常规分录的普通日记账。
From the journals, transactions are posted to the nominal ledger, which contains all the individual T-accounts. Each account is balanced off at the end of a period, and the balances are used to prepare the trial balance.
交易从日记账过账到总分类账，其中包含所有单独的 T 型账户。每个账户在期末结平，余额用于编制试算平衡表。
Subsidiary ledgers, such as the sales ledger and purchases ledger, record individual customer and supplier accounts. The total balances of these subsidiary ledgers are reconciled with the control accounts in the nominal ledger.
明细分类账，如销售分类账和采购分类账，记录各个客户和供应商的账户。这些明细分类账的总余额与总账中的控制账户进行调节。
5. Trial Balance | 试算平衡表
The trial balance lists all the balances from the nominal ledger in debit and credit columns. Its main purpose is to check the arithmetic accuracy of the double-entry system: if total debits equal total credits, the books are said to be 'in balance'.
试算平衡表将所有总账余额按借方和贷方分列。其主要目的是检查复式记账体系的算术准确性：如果借方合计等于贷方合计，则账目被认为是“平衡的”。
A balanced trial balance does not guarantee the complete absence of errors. Errors of omission, commission, principle, original entry, compensating errors, and complete reversal of entries will not be revealed by the trial balance.
试算平衡表平衡并不能保证完全没有错误。遗漏错误、账户记错、原则性错误、原始分录错误、抵消性错误以及借贷方向完全颠倒的错误不会被试算平衡表揭示。
If the trial balance does not balance, a suspense account is opened with the difference temporarily recorded. Common errors causing an imbalance include single entries, transposition errors and incorrect addition in the ledger accounts.
如果试算平衡表不平衡，则开设一个暂记账户，暂时记录差额。导致不平衡的常见错误包括单边分录、数字错位以及分类账账户加总错误。
6. Financial Statements: Income Statement | 财务报表：利润表
The income statement (formerly known as the profit and loss account) measures the financial performance of a business over a specific period. It follows the structure:
利润表（原称损益表）衡量企业在特定期间内的财务业绩。其结构如下：
Sales Revenue – Cost of Sales = Gross Profit
Gross Profit + Other Income – Expenses = Net Profit
Cost of sales consists of opening inventory plus purchases less closing inventory. Purchases should be adjusted for returns outwards, and carriage inwards is added to the cost of purchases.
销售成本由期初存货加购货减期末存货构成。购货需调整购货退回，购货运费计入购货成本。
Expenses are classified into distribution costs, administrative expenses and finance costs. Only expenses incurred in the accounting period, in accordance with the accruals concept, should be included.
费用分为分销成本、管理费用和财务费用。按照应计制概念，仅应计入归属于本期会计期间的费用。
7. Financial Statements: Statement of Financial Position | 财务报表：财务状况表
The statement of financial position (balance sheet) shows the assets, liabilities and capital of the business at a specific point in time. It is presented in a vertical format under Eduqas requirements, with net assets equalling capital employed.
财务状况表（资产负债表）展示企业于某一特定时点的资产、负债和资本。根据 Eduqas 要求，采用垂直格式列报，使净资产等于运用资本。
Non-current assets are long-term items such as premises, machinery and vehicles, shown at net book value after accumulated depreciation. Current assets include inventories, trade receivables, prepayments and cash, listed in reverse order of liquidity.
非流动资产是诸如厂房、机器和车辆等长期项目，按扣除累计折旧后的账面净值列示。流动资产包括存货、应收贸易款、预付费用和现金，按流动性逆序排列。
Current liabilities are obligations due within one year, such as trade payables and accruals. Non-current liabilities are due after more than one year, typically bank loans. Capital consists of the opening capital plus net profit less drawings.
流动负债是一年内到期的债务，如应付贸易款和应计费用。非流动负债是超过一年到期的债务，一般为银行贷款。资本由期初资本加净利润减提款构成。
8. Depreciation of Non-Current Assets | 非流动资产的折旧
Depreciation allocates the cost of a non-current asset over its useful life, following the matching concept. Two common methods are the straight-line method and the reducing balance method.
折旧将非流动资产的成本在其使用年限内分摊，符合配比概念。两种常用方法是直线法和余额递减法。
Under the straight-line method, the annual depreciation charge is calculated as:
在直线法下，年折旧额的计算公式为：
Annual Depreciation = (Cost – Residual Value) ÷ Useful Life
The reducing balance method applies a fixed percentage to the net book value each year, resulting in higher depreciation charges in the early years of an asset's life.
余额递减法每年对账面净值应用一个固定百分比，导致资产使用寿命早期的折旧费用较高。
In the accounting records, an adjusting entry debits the income statement with the depreciation expense and credits the provision for depreciation account, which is deducted from the cost of the asset in the statement of financial position.
在会计记录中，调整分录将折旧费用借记利润表，并贷记折旧准备账户，该准备金在财务状况表中从资产成本中扣减。
9. Bad Debts and Allowance for Doubtful Debts | 坏账与呆账准备
A bad debt arises when a customer becomes unable to pay the amount owed. It is written off as an expense in the income statement and removed from trade receivables in the statement of financial position.
当客户无力偿还欠款时，产生坏账。坏账在利润表中作为费用核销，并从财务状况表的应收贸易款中移除。
An allowance for doubtful debts (provision) is created to reflect the estimated amount of trade receivables that may not be collected. This is an application of the prudence concept. The allowance is reviewed each year and adjusted accordingly.
设立呆账准备（准备金）是为了反映估计无法收回的应收贸易款金额。这是谨慎性概念的应用。准备金每年重估并相应调整。
The movement in the allowance is charged to the income statement: an increase in the allowance creates an additional expense, while a decrease is treated as other income.
准备金的变动计入利润表：准备金增加产生额外费用，准备金减少则作为其他收益处理。
10. Accruals and Prepayments | 应计与预付项目
To apply the accruals concept, adjustments must be made for expenses and income that span accounting periods. An accrual is an expense incurred but not yet paid; a prepayment is a payment made in advance for an expense of a future period.
为了应用应计制概念，必须对跨越会计期间的费用和收入进行调整。应计费用指已发生但尚未支付的费用；预付费用指为未来期间的费用提前支付的款项。
Accrued expenses are added to the relevant expense in the income statement and shown as a current liability. Prepaid expenses are deducted from the expense and shown as a current asset.
应计费用在利润表中加计入相关费用，并作为流动负债列示。预付费用从费用中扣除，并作为流动资产列示。
For example, if rent paid during the year is £12,000 but £1,000 is prepaid, the income statement charge is £11,000 and the prepayment appears in the statement of financial position. Accrued income, such as commission receivable, works on the same logic.
例如，如果年内支付的租金为 12,000 英镑，但其中 1,000 英镑为预付，则利润表中的费用为 11,000 英镑，预付项目出现在财务状况表中。应计收入，如应收佣金，也遵循相同逻辑。
11. Bank Reconciliation and Control Accounts | 银行对账与控制账户
A bank reconciliation compares the cash book balance with the bank statement balance, explaining timing differences such as unpresented cheques and deposits in transit. It helps identify errors and unauthorised transactions.
银行对账单调节将现金簿余额与银行对账单余额进行比较，解释未兑现支票和未入账存款等时间性差异。它有助于发现错误和未经授权的交易。
The reconciliation starts with the updated cash book balance, adds unpresented cheques and subtracts deposits not yet credited (or vice versa, depending on the starting point) to arrive at the bank statement balance.
调节过程从更新后的现金簿余额开始，加上未兑现支票，减去尚未贷记的存款（或反之，取决于起点），以得出银行对账单余额。
Control accounts, namely the sales ledger control account and purchases ledger control account, provide a check on the accuracy of the individual customer and supplier accounts. They are part of the double-entry system and their balances should equal the total of the relevant subsidiary ledger.
控制账户，即销售分类账控制账户和采购分类账控制账户，用于检查各个客户和供应商账户的准确性。它们是复式记账体系的一部分，其余额应等于相关明细分类账的合计。
12. Ratio Analysis | 比率分析
Ratios help interpret financial statements by comparing related figures. Profitability ratios such as gross profit margin and net profit margin measure how effectively a business generates profit from sales.
比率通过比较相关数据帮助解读财务报表。盈利能力比率，如毛利率和净利率，衡量企业从销售中获取利润的效率。
Gross Profit Margin = (Gross Profit ÷ Sales Revenue) × 100
Net Profit Margin = (Net Profit ÷ Sales Revenue) × 100
Liquidity ratios assess a business's ability to meet short-term obligations. The current ratio compares current assets to current liabilities, while the acid test ratio (quick ratio) excludes inventory from current assets for a stricter test.
流动性比率评估企业履行短期义务的能力。流动比率比较流动资产与流动负债，而酸性测试比率（速动比率）从流动资产中剔除存货，进行更严格的测试。
Current Ratio = Current Assets : Current Liabilities
Acid Test Ratio = (Current Assets – Inventory) : Current Liabilities
Rate of inventory turnover measures how quickly inventory is sold. It is calculated as Cost of Sales divided by Average Inventory. A high turnover suggests efficient inventory management.
存货周转率衡量存货的销售速度。其计算公式为销售成本除以平均存货。高周转率表明存货管理效率较高。
Trade receivables and trade payables settlement periods show the average number of days to collect debts and pay suppliers, respectively. These ratios provide insights into working capital management.
应收贸易款和应付贸易款结算期分别显示收回应收款项和支付供应商的平均天数。这些比率提供了对营运资金管理的深入洞察。
