- Standard errors in parentheses. Asterisks indicate the significance level; *at 10 percent, **at 5 percent, and ***at 1 percent
- This analysis uses the productivity estimated in Column 3 of Table 3, the baseline result of this study
- The BOF dummy indicates the BOF’s average productivity advantage against the OHF in each specification
- Fixed effects: Year fixed effects are controlled for in all specifications. Furnace means that there are furnace dummies in the estimation. Firm × year means that firm dummies, year dummies, and interaction terms of the firm and year dummies are included; the same is the case for plant × year and technology × year
