Individual skill

jfr-heterogeneity

Use when the heterogeneity analysis of a 《金融研究》 (Journal of Financial Research) manuscript is too coarse or atheoretical — to cut along finance-relevant dimensions (ownership, bank type, market segment, financing constraint, region) that the mechanism predicts, not arbitrary splits.

# 异质性分析(jfr-heterogeneity)

## 触发时机

- 没做异质性,或只切了"东中西"
- 切分维度与机制无关,纯粹试着切
- 审稿人会问"这效应对谁更强、为什么"

## 原则:异质性要由机制预测,而非数据探鱼

每个切分维度都应能从渠道机制**事前推断方向**:渠道说该群体更敏感,数据若印证,机制更可信;若反向,要么机制错、要么有竞争渠道。

## 金融相关的切分维度(对照表)
