er-heterogeneity

separate

Use when designing or writing the heterogeneity section of an 《经济研究》 (Economic Research Journal) manuscript — choosing which dimensions to cut, justifying each cut theoretically, presenting subsample results with coefficient-difference tests, and wiring at least one dimension back to the mechanism story so heterogeneity doubles as mechanism evidence. 使用时机：主结果已稳健但只切了"东中西"一类单一维度、审稿人要求补做异质性、或切分维度缺乏理论指引时。

When to use

• Designing heterogeneity section for Economic Research Journal
• Choosing heterogeneity dimensions
• Justifying subsample cuts theoretically
• Presenting subsample results with coefficient-difference tests
• Linking heterogeneity to mechanism story
• Handling reviewer requests for heterogeneity
• Selecting between subsample tables and interaction terms

When not to use

• Using control variable interactions as heterogeneity
• Interpreting subsamples with N < 100
• Cutting 8 dimensions without significance
• Ignoring conflict between heterogeneity and mechanism
