Individual skill

cre-identification

Use when the empirical identification strategy is the bottleneck for a 《中国农村经济》 manuscript — micro-household / village-level quasi-experimental designs (DID, IV, RDD, PSM). Stress-tests the design and the rural-specific endogeneity before drafting tables.

# 因果识别策略(cre-identification)

## 触发时机

- 实证主体仅有描述统计 + OLS + 控制变量
- 自变量是农户的**自选择行为**(入合作社、外出务工、采用新技术、参与流转),但没处理自选择内生性
- DID 用了 TWFE 但没回应近年异质性处理批评(Goodman-Bacon, de Chaisemartin, Sun-Abraham, Callaway-Sant'Anna)
- IV 第一阶段 F 弱 / 工具变量排他性疑虑
- PSM 只做了匹配但没讨论"不可观测的选择性"
