## Definition
|
||
TAM/SAM/SOM 是市场规模分析的三层模型，用于量化市场机会的大小和可实现性。
|
||
|
||
## Three Layers
|
||
- **TAM（Total Addressable Market）**：总可寻址市场，自顶向下和自底向上分析
|
||
- **SAM（Serviceable Addressable Market）**：可服务市场，考虑地理和业务约束后的现实市场机会
|
||
- **SOM（Serviceable Obtainable Market）**：可获得市场，通过竞争分析确定的可实现市场份额
|
||
|
||
## Analysis Methods
|
||
- Top-down Analysis：自顶向下，从宏观市场向下分解
|
||
- Bottom-up Analysis：自底向上，从细分市场向上聚合
|
||
- Validation：交叉验证确保准确性
