It is not enough for empirical papers to report only one regression result, because the significance of variables may change under different model settings.

Only under different model settings, similar results are obtained, which is robust and credible.

For the report of robustness test results, if the length is short, it can be classified as "regression results" in the previous part; If you do more robustness tests, it can be used as a part of the paper alone.

(2) Conclusion

The conclusion is the last part of the paper, which summarizes the full text and leaves a final impression on readers.

The conclusion part usually briefly reviews the research problems, measurement methods and main conclusions of this paper, and can also reiterate the unique contribution of this paper.

Because any paper has limitations, it can also point out the future improvement space and research direction. Many readers will read the introduction and conclusion before deciding whether to read the text, so the conclusion part is also very important.
