在分享具体方法之前，我们先了解两个关键概念：SIC代码和NAICS代码。
Before sharing specific methods, let's understand two key concepts: SIC codes and NAICS codes.
SIC代码 vs NAICS代码
SIC Codes vs NAICS Codes
SIC代码（标准工业分类系统）：
SIC Codes (Standard Industrial Classification System):
- 1930年代开发
- 4位数字编码
- 1987年后不再更新但仍广泛使用
- Developed in the 1930s
- 4-digit coding
- No updates since 1987 but still widely used
NAICS代码（北美工业分类系统）：
NAICS Codes (North American Industry Classification System):
- 1997年建立
- 6位数字编码
- 美加墨三国通用标准
- Established in 1997
- 6-digit coding
- Common standard for US, Canada and Mexico
核心差异
Key Differences
NAICS代码通过6位编码提供了比4位SIC代码更高的精确度，采用纯粹的生产导向结构，而SIC系统则混合了生产和市场导向逻辑。
NAICS codes provide higher precision than 4-digit SIC codes through 6-digit coding, adopting a purely production-oriented structure, while the SIC system mixes production and market-oriented logic.
