Jfr Heterogeneity

ASecurity

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)

| 维度 | 适用线别 | 机制预期 |
|------|----------|----------|
| **所有制**(国有 vs 民营) | 公司金融 | 软预算/隐性担保 → 信贷与融资约束差异 |
| **银行类型**(国有大行/股份/城商/农商) | 银行信贷 | 资本约束、客户结构 → 风险承担与信贷反应差异 |
| **融资约束**(KZ/SA/WW 指数等) | 公司金融 | 约束越紧,信贷/资产负债表渠道越强 |
| **市场分割/上市板块**(主板/科创/创业/北交) | 资本市场 | 制度差异 → 定价与信息效率差异 |
| **货币政策环境**(宽松 vs 紧缩期) | 宏观传导 | 风险承担渠道在宽松期更强 |
| **地区/金融发展** | 两线皆可 | 金融发展水平调节传导强度 |
| **企业规模/行业/抵押品** | 公司金融 | 抵押品多寡 → 资产负债表渠道 |

## 写法要点

- 每个维度**先讲机制预期,再看结果**,结果与预期对话
- 区分**统计显著的差异**与**经济上有意义的差异**(用组间系数差异检验,而非各自显著)
- 异质性应反哺机制结论(与 jfr-mechanism 闭环)

## 自检清单

- [ ] 切分维度由机制事前预测方向
- [ ] 维度是金融相关(所有制/银行类型/约束/市场分层等),非笼统地理
- [ ] 报告组间系数差异检验,不只看各组显著性
- [ ] 异质性方向与机制一致;不一致已解释
- [ ] 不堆砌无理论的切分

## 反模式

- 只切东中西/大小企业,无机制对话
- 各组分别显著就宣称"存在异质性",不做差异检验
- 切了十几个维度找显著,事后编故事
- 把所有银行/所有上市公司当同质,错失关键分层

## 输出格式

```
【切分维度】[所有制, 银行类型, 融资约束, 市场分层, ...]
【机制预期对齐】对齐 / 部分 / 反向 <说明>
【组间差异检验】做了 / 未做
【反哺机制】是 / 否
【下一步】jfr-tables-figures
```
