When I was a junior, I didn't study econometrics and wanted to write a paper, but the papers that came down from the Internet were basically empirical analysis and I couldn't understand them. . What should we do? Qualitative paper.

Articles written with econometric models are all about analyzing data, and data is the representation of reality, so using measurement means analyzing real data, and the amount of data is often very large.

Qualitative papers are generally used to explain logical thinking or understanding of problems, which can be analyzed by mathematical models (such as Thoreau's "A Contribution to Economic Growth Theory") or established by game theory models (such as Mr. Lu Fucai's "Game Analysis of Low-end Locking of China Enterprises under the Global Value Network"). It can also be written by logical induction and comparison (such as Mundell's theory of optimal currency area), or it can be abstracted into several concepts to establish the relationship between these concepts (such as Marx's analysis of surplus value theory with concrete labor and abstract labor).

I hope I can help you.
