State Fragility Index (CSP)国家脆弱性指数 (CSP)

The State Fragility Index (SFI) measures country fragility across four dimensions — security, political, economic, and social — each evaluated on both effectiveness and legitimacy. Covering 167 countries from 1995 onwards, the composite index ranges from 0 (no fragility) to 25 (extreme fragility).

Each dimension is scored 0–3 on effectiveness and 0–3 on legitimacy, summing to the total SFI. It is a widely used measure for assessing state capacity and conflict risk.

国家脆弱性指数（SFI）从安全、政治、经济和社会四个维度衡量国家脆弱性，每个维度评估有效性（effectiveness）和合法性（legitimacy）两方面。覆盖 167 个国家，自 1995 年起逐年更新，综合指数范围为 0（无脆弱性）至 25（极度脆弱）。

各维度按 0–3 分打分，加总构成 SFI。该指数广泛用于评估国家能力和冲突风险。
