Standardized World Income Inequality Database标准化世界收入不平等数据库

Developed by Frederick Solt, the Standardized World Income Inequality Database (SWIID, Version 9.92) synthesizes multiple authoritative income‑distribution sources and takes the Luxembourg Income Study as the benchmark. Maximizing cross‑country and cross‑temporal comparability while ensuring broad coverage, it provides standardized Gini coefficients for market (pre‑tax, pre‑transfer) and disposable (post‑tax, post‑transfer) income, alongside absolute and relative redistribution indicators for 199 economies dating back to 1960. Widely used in cross‑national social‑science research, it supplies datasets compatible with Stata and R for quantitative empirical analysis.

标准化世界收入不平等数据库（SWIID，9.92 版）由 Frederick Solt 构建，整合多方权威收入分配数据源并以卢森堡收入研究作为参照基准。该数据库在实现广泛样本覆盖的同时最大限度提升跨国、跨时期数据可比性，提供 199 个经济体自 1960 年以来标准化的市场收入（税前转移前）、可支配收入（税后转移后）基尼系数，以及绝对再分配、相对再分配指标，被广泛应用于跨国社会科学研究，提供适配 Stata 与 R 格式的数据供实证定量分析使用。
