1. What is Accounting? | 什么是会计？
Accounting is the systematic process of recording, classifying, summarising, and interpreting financial transactions. Its main purpose is to provide information that helps owners, managers, and other stakeholders make informed economic decisions. Without accounting, a business would have no clear picture of its financial health.
会计是对财务交易进行记录、分类、汇总和解读的系统化过程。其主要目的是提供信息，帮助所有者、管理者和其他利益相关者做出明智的经济决策。没有会计，企业就无法清晰了解其财务状况。
Bookkeeping forms the part of accounting that deals with the daily recording of transactions. This includes sales, purchases, payments, and receipts. While bookkeeping focuses on accurate record‑keeping, accounting takes it further by analysing the data and preparing reports like the income statement and balance sheet.
簿记是会计的一部分，负责日常交易的记录，包括销售、采购、付款和收款。簿记侧重于准确记录，而会计则进一步分析数据并编制利润表和资产负债表等报告。
2. The Accounting Equation | 会计等式
The accounting equation is the foundation of double‑entry bookkeeping. It states that at any point in time, a business’s resources (assets) are funded by either obligations to outsiders (liabilities) or the owner’s stake (equity). The equation is always in balance after every transaction.
会计等式是复式记账的基石。它表明在任何时候，企业的资源（资产）都是由对外部人的义务（负债）或所有者的投入（权益）来提供资金的。每笔交易发生后，该等式始终保持平衡。
Assets = Liabilities + Owner’s Equity
资产 = 负债 + 所有者权益
For example, if the owner starts a business by contributing $10,000 cash, assets (cash) increase by $10,000 and equity (capital) increases by $10,000. The equation remains balanced. If the business later borrows $5,000 from a bank, cash rises by $5,000 and liabilities (bank loan) rise by $5,000.
例如，如果所有者投入10,000美元现金创业，资产（现金）增加10,000美元，同时权益（资本）增加10,000美元。等式保持平衡。如果该企业后来从银行借款5,000美元，现金增加5,000美元，负债（银行贷款）增加5,000美元。
3. Understanding Assets, Liabilities and Equity | 理解资产、负债和权益
An asset is a resource controlled by the business as a result of past events, and from which future economic benefits are expected to flow to the business. Examples include cash, accounts receivable (debtors), inventory, equipment, and premises.
资产是由企业因过去事项而控制的、预期会给企业带来未来经济利益的资源。例如现金、应收账款（债务人）、存货、设备和房屋建筑物。
A liability is a present obligation of the business arising from past events, the settlement of which is expected to lead to an outflow of resources. Common liabilities are accounts payable (creditors), bank loans, and mortgages.
负债是企业因过去事项而产生的现时义务，预计该义务的履行会导致资源流出。常见的负债包括应付账款（债权人）、银行贷款和抵押贷款。
Owner’s equity represents the owner’s residual interest in the assets after deducting all liabilities. It includes the capital introduced by the owner plus retained profits, less any drawings. Equity is sometimes called ‘net assets’ or ‘capital’.
所有者权益是所有者扣除所有负债后对资产享有的剩余权益。它包括所有者投入的资本加上留存利润，减去任何提款。权益有时也称为“净资产”或“资本”。
4. Double‑Entry Bookkeeping System | 复式记账系统
Double‑entry bookkeeping is based on the idea that every transaction has two effects on the accounting equation. For every debit entry, there must be a corresponding credit entry of equal amount. This ensures that the books always balance and errors can be detected more easily.
复式记账基于这样一种理念：每笔交易都会对会计等式产生两方面的影响。每发生一笔借方记录，就必须有相等金额的贷方记录。这确保了账簿始终平衡，并更容易发现错误。
Accounts are maintained in a ‘T‑account’ format, with a left side (debit) and a right side (credit). The name comes from the table’s shape resembling the letter T. Below is a simple representation of a cash account.
账户以“T型账户”格式维护，左边为借方，右边为贷方。这个名称源于表格形状类似字母T。下面是一个现金账户的简单表示。
| Dr Cash | Cr Cash |
|---|---|
| Date | Particulars | Amount | Date | Particulars | Amount |
| 1 Jan Capital $10,000 | 3 Jan Equipment $3,000 |
| 5 Jan Sales $2,000 | 7 Jan Rent $500 |
In this cash account, the debit side records all cash inflows (increases), and the credit side records all cash outflows (decreases). At the end of the period, the account is balanced to find the remaining cash.
在这个现金账户中，借方记录所有现金流入（增加），贷方记录所有现金流出（减少）。在期末，账户将结出余额以确定剩余现金。
5. Debits and Credits: The Rules | 借方与贷方：记账规则
Learning the rules of debit and credit is essential. The effect of a debit or credit entry depends on the type of account. It is not simply ‘debit means increase’ – it depends on whether the account is an asset, liability, equity, income, or expense.
掌握借方和贷方的规则至关重要。借记或贷记的影响取决于账户的类型。并非简单地“借记就是增加”——这取决于账户属于资产、负债、权益、收入还是费用。
The modern rules can be summarised as follows: to increase an asset, debit the account; to decrease an asset, credit it. For liabilities and equity, the opposite applies – credit to increase, debit to decrease. Income accounts are credited to increase, while expense accounts are debited to increase.
现代记账规则可以总结如下：增加资产时，借记该账户；减少资产时，贷记该账户。对于负债和权益，则相反——贷记增加，借记减少。收入账户贷记表示增加，而费用账户借记表示增加。
For example, when a business buys stationery for cash, the expense account ‘Stationery’ is debited (increase in expense) and the asset account ‘Cash’ is credited (decrease in asset). Both effects are recorded with the same dollar amount.
例如，当企业用现金购买文具时，费用账户“文具费”借记（费用增加），资产账户“现金”贷记（资产减少）。两方面的记录金额相等。
- Assets: Debit ↑, Credit ↓
- Liabilities: Debit ↓, Credit ↑
- Equity: Debit ↓, Credit ↑
- Income: Debit ↓, Credit ↑
- Expenses: Debit ↑, Credit ↓
- 资产：借方增加，贷方减少
- 负债：借方减少，贷方增加
- 权益：借方减少，贷方增加
- 收入：借方减少，贷方增加
- 费用：借方增加，贷方减少
6. Source Documents and Journals | 原始凭证与日记账
Every accounting entry starts with a source document that provides evidence of a transaction. Examples include invoices, receipts, debit notes, credit notes, and bank statements. These documents are the original records that support all bookkeeping entries.
每笔会计分录都始于提供交易证据的原始凭证。例如发票、收据、借项通知单、贷项通知单和银行对账单。这些单据是支持所有簿记分录的原始记录。
Transactions are first recorded in chronological order in journals, which are also called ‘books of prime entry’. The main journals include the sales journal, purchases journal, cash book, and general journal. The general journal is used for transactions that do not fit into the special journals, such as depreciation adjustments or correction of errors.
交易首先按时间顺序记录在日记账中，日记账也称为“原始分录簿”。主要的日记账包括销售日记账、采购日记账、现金日记账和普通日记账。普通日记账用于记录不适合特殊日记账的交易，例如折旧调整或错误更正。
Once the journal entry is complete, the amounts are posted to the individual accounts in the general ledger. Posting means transferring the debit and credit amounts from the journal to the relevant T‑accounts. At this stage, each account accumulates all movements for a period.
日记账分录完成后，金额会被过账到总分类账中的各个账户。过账是指将借项和贷项金额从日记账转移到相关的T型账户。在此阶段，每个账户汇总了当期的所有变动。
7. Ledger Accounts and Trial Balance | 分类账与试算平衡表
A ledger account summarises all the transactions affecting a particular item, such as rent, cash, or sales. Each account has a debit and a credit side. After all entries are posted, the account is balanced to find the net balance, which is either a debit or credit balance.
分类账账户汇总了影响特定项目（如租金、现金或销售）的所有交易。每个账户都有借方和贷方。所有分录过账后，账户会结出净余额，该余额要么是借方余额，要么是贷方余额。
At regular intervals, usually at the end of a month or a year, a trial balance is prepared. This is a list of all ledger accounts and their closing balances, placed in two columns for debits and credits. The main purpose is to check the arithmetic accuracy of the double‑entry records.
定期（通常在月末或年末）会编制试算平衡表。这是一份列示所有分类账账户及其期末余额的清单，分为借方和贷方两栏。其主要目的是检查复式记录的算术准确性。
A trial balance is not part of the formal financial statements, but it is a vital internal document. If the total debits equal total credits, it suggests the ledger is arithmetically correct, although it does not guarantee that there are no errors, such as omitting a transaction or posting to the wrong account.
试算平衡表不是正式财务报表的一部分，但它是重要的内部文件。如果借方总额等于贷方总额，则表明分类账在算术上是正确的，但这并不保证没有错误，例如遗漏交易或过账到错误的账户。
| Account Name | Debit $ | Credit $ |
|---|---|---|
| Cash | 5,000 | |
| Accounts Receivable | 2,300 | |
| Equipment | 4,000 | |
| Accounts Payable | 1,800 | |
| Bank Loan | 3,000 | |
| Capital | 6,000 | |
| Sales | 1,500 | |
| Rent Expense | 500 | |
| Totals | 11,800 | 11,800 |
In the trial balance above, the total debit amounts equal total credit amounts, indicating that the ledger balances are mathematically correct.
在上面的试算平衡表中，借方总额等于贷方总额，表明分类账余额在数学上是正确的。
8. Introduction to the Income Statement | 利润表简介
The income statement, also known as the profit and loss statement, measures a business’s financial performance over a period of time. It reports the revenue earned and the expenses incurred, arriving at the net profit or net loss.
利润表（也称损益表）衡量企业在一定时期内的财务业绩。它报告所获得的收入和发生的费用，最终得出净利润或净亏损。
The basic formula for an income statement is:
利润表的基本公式是：
Net Profit (or Net Loss) = Total Revenue − Total Expenses
净利润（或净亏损）= 总收入 − 总费用
Revenue includes sales of goods or services. Expenses are the costs incurred to generate that revenue, such as rent, wages, utilities, and cost of goods sold. If revenue exceeds expenses, the business makes a profit. If expenses exceed revenue, the business makes a loss.
收入包括销售商品或服务的所得。费用是为产生该收入而发生的成本，例如租金、工资、水电费和销售成本。如果收入超过费用，企业就获利；如果费用超过收入，企业就亏损。
For example, if a small business earns $8,000 in sales and has $5,500 in total expenses, its net profit is $2,500. This profit is then added to the owner’s equity in the balance sheet.
例如，如果一家小企业获得8,000美元销售收入，总费用为5,500美元，则其净利润为2,500美元。该利润随后会加计入资产负债表中的所有者权益。
9. Introduction to the Statement of Financial Position (Balance Sheet) | 财务状况表（资产负债表）简介
The statement of financial position, commonly called the balance sheet, shows the assets, liabilities, and equity of a business at a specific point in time. It is a financial snapshot that proves the accounting equation is in balance.
财务状况表，通常称为资产负债表，显示企业在某一特定时点的资产、负债和权益。它是一个财务快照，证明会计等式处于平衡状态。
The balance sheet is presented with assets on one side (or at the top) and liabilities plus equity on the other side (or below). Current assets (such as cash and accounts receivable) are listed separately from non‑current assets (such as machinery and buildings). Similarly, current liabilities are those due within one year, while non‑current liabilities are long‑term obligations.
资产负债表中资产列在一侧（或上部），负债和权益列在另一侧（或下部）。流动资产（如现金和应收账款）与非流动资产（如机器和建筑物）分开列示。同样，流动负债是一年内到期的债务，而非流动负债则是长期义务。
Below is a simplified layout of a balance sheet for a sole trader:
以下是个体经营者资产负债表的简化布局：
| ABC Trading Statement of Financial Position as at 31 December | |
|---|---|
| Assets | $ |
| Non‑current assets Equipment |
4,000 |
| Current assets Cash Accounts receivable Inventory |
5,000 2,300 1,200 |
| Total assets | 12,500 |
| Liabilities | |
| Current liabilities Accounts payable |
1,800 |
| Non‑current liabilities Bank loan |
3,000 |
| Total liabilities | 4,800 |
| Equity Capital Retained profit |
6,000 1,700 |
| Total equity and liabilities | 12,500 |
This simple balance sheet shows total assets of $12,500, exactly matching the total of liabilities ($4,800) and equity ($7,700). The link between the income statement and balance sheet is clear, as the profit earned during the period increases retained profit within equity.
这个简单的资产负债表显示总资产为12,500美元，与负债（4,800美元）和权益（7,700美元）的总和完全一致。利润表与资产负债表之间的联系显而易见，因为当期赚取的利润会增加权益中的留存利润。
10. Key Accounting Concepts and Conventions | 核心会计概念与惯例
Accounting is governed by a set of concepts and conventions that ensure consistency, reliability, and comparability of financial statements. Even at Year 9 level, it is helpful to be familiar with the most fundamental ones.
会计受一系列概念和惯例的约束，以确保财务报表的一致性、可靠性和可比性。即使在Year 9阶段，熟悉最基本的概念也是有益的。
The business entity concept states that the business is treated as separate from its owner. Only transactions that affect the business are recorded; the owner’s personal transactions are kept entirely separate. This ensures that the financial statements reflect only the business’s financial position and performance.
会计主体概念指出，企业被视为独立于其所有者的实体。只有影响企业的交易才会被记录；所有者的个人交易被完全分开。这确保财务报表仅反映企业的财务状况和业绩。
The money measurement concept means that only transactions that can be expressed in monetary terms are recorded. Non‑financial events, however important, are not included in the accounting records. For example, the health of a manager is not recorded, but a payment for medical insurance would be.
货币计量概念意味着只有能够用货币量化的交易才被记录。非财务事件无论多么重要，均不纳入会计记录。例如，管理者的健康状况不会被记录，但为医疗保险支付的款项则会被记录。
The going concern concept assumes that the business will continue to operate for the foreseeable future. This assumption allows the accountant to value assets at historical cost rather than at liquidation value. If this assumption is not valid, the financial statements must be prepared on a different basis.
持续经营概念假设企业在可预见的未来将继续经营。这一假设允许会计师按历史成本而非清算价值对资产进行计价。如果该假设不成立，则必须按不同的基础编制财务报表。
The consistency convention requires that the same accounting methods are applied from one period to the next, unless a change is necessary and clearly stated. This allows meaningful comparison of performance over time. For instance, if a business uses the straight‑line depreciation method, it should not suddenly switch to a different method without disclosure.
一致性惯例要求除非有必要变更且明确说明，否则各期应采用相同的会计方法。这使得不同时期的业绩可以进行有意义的比较。例如，如果企业采用直线折旧法，就不应在未披露的情况下突然改用其他方法。
11. Common Transactions and Their Double‑Entry Effects | 常见交易及其复式记账影响
Let us bring the concepts together by analysing a few typical transactions. Understanding how everyday business activities affect the ledgers is a vital skill.
让我们通过分析一些典型交易来整合这些概念。理解日常商业活动如何影响分类账是一项关键技能。
Transaction 1: Owner invests cash into the business. The double entry is: debit Cash (increase in asset) and credit Capital (increase in equity). This shows the inflow of funds from the owner.
交易1：所有者向企业投入现金。 复式分录为：借记现金（资产增加），贷记资本（权益增加）。这显示了来自所有者的资金流入。
Transaction 2: Purchase of inventory on credit. Debit Purchases (or Inventory) (increase in expense/asset) and credit Accounts Payable (increase in liability). This transaction increases what the business owns and also increases what it owes.
交易2：赊购存货。 借记采购（或存货）（费用/资产增加），贷记应付账款（负债增加）。这笔交易增加了企业拥有的资产，同时也增加了它所欠的债务。
Transaction 3: Sale of goods for cash. Debit Cash (increase in asset) and credit Sales (increase in income). The business receives cash and earns revenue simultaneously.
交易3：现销商品。 借记现金（资产增加），贷记销售收入（收入增加）。企业同时收到现金并赚取收入。
Transaction 4: Payment of wages by cheque. Debit Wages Expense (increase in expense) and credit Bank (decrease in asset). This reduces the bank balance and records the cost of labour.
交易4：以支票支付工资。 借记工资费用（费用增加），贷记银行存款（资产减少）。这减少了银行存款余额并记录了人工成本。
Transaction 5: Repayment of a bank loan. Debit Bank Loan (decrease in liability) and credit Bank (decrease in asset). Both the liability and the asset fall, keeping the equation in balance.
交易5：偿还银行贷款。 借记银行贷款（负债减少），贷记银行存款（资产减少）。负债和资产同时减少，使等式保持平衡。
12. Practical Tips and Summary | 实用技巧与总结
Mastering these core topics requires regular practice. Start by drawing T‑accounts for every transaction until the debit and credit rules become second nature. Always check that the accounting equation remains balanced after each entry.
掌握这些核心主题需要定期练习。从为每笔交易绘制T型账户开始，直到借货规则成为第二天性。每次分录后都要检查会计等式是否保持平衡。
When preparing a trial balance, list all accounts with their final balances. The total of the debit column must equal the total of the credit column. If they differ, re‑check the arithmetic, ensure every transaction has been recorded twice, and verify that the opening balances were brought down correctly.
在编制试算平衡表时，列出所有账户及其最终余额。借方栏总和必须等于贷方栏总和。如果不相等，请重新检查计算，确保每笔交易都已记录两次，并核实期初余额已正确结转。
The income statement and balance sheet are the key outputs of the accounting system. The income statement shows how the business performed, while the balance sheet shows its financial position. Both are linked through the profit or loss for the period, which adjusts the owner’s equity.
利润表和资产负债表是会计系统的关键输出。利润表显示企业的经营成果，而资产负债表则显示其财务状况。
