在IB商务管理和Edexcel A-Level商务课程中，波特五力模型是分析行业竞争态势和盈利能力的基本框架。该模型由迈克尔·波特于1979年提出，通过考察影响竞争的五个关键力量，帮助企业及学生评估市场吸引力。掌握这一工具对取得考试成功至关重要，因为它经常出现在结构化问题、案例分析和评价题型中。
1. What is Porter’s Five Forces? | 什么是波特五力模型？
The Five Forces model identifies the five competitive forces that determine the long-term profit potential of an industry: the threat of new entrants, the bargaining power of suppliers, the bargaining power of buyers, the threat of substitute products or services, and the intensity of rivalry among existing competitors. By evaluating these forces, a business can develop strategies to position itself more favourably.
五力模型明确了决定行业长期利润潜力的五种竞争力：新进入者的威胁、供应商的议价能力、购买者的议价能力、替代产品或服务的威胁，以及现有竞争对手之间的竞争强度。通过评估这些力量，企业可以制定策略以占据更有利的位置。
It is important to note that the Five Forces framework is not about describing the attractiveness of a single company but about the entire industry. Therefore, the analysis must be conducted at the industry level, considering all players.
需要注意的是，五力框架并非描述单个公司的吸引力，而是整个行业。因此，分析必须在行业层面进行，并考虑所有参与者。
| Competitive Force | 竞争力 | Factors Increasing the Threat/Power | 提升威胁/力量的因素 |
|---|---|---|---|
| Threat of New Entrants | 新进入者威胁 | Low barriers to entry, weak brand identity, easy access to distribution | 低进入壁垒、品牌认同弱、分销渠道易得 |
| Bargaining Power of Suppliers | 供应商议价能力 | Few suppliers, high switching costs, no substitutes for inputs | 供应商少、转换成本高、投入品无替代 |
| Bargaining Power of Buyers | 购买者议价能力 | Large purchases, low product differentiation, price sensitivity | 大宗采购、产品差异化低、价格敏感 |
| Threat of Substitutes | 替代品威胁 | 更多咨询请联系16621398022（同微信）
