The so-called empirical research refers to the methodological thought of summarizing universal conclusions or laws from a large number of empirical facts through scientific induction, then deducing some conclusions or laws through scientific logical deduction, and then bringing these conclusions or laws back to reality for testing.
The research purpose of this methodology is to analyze the "what" of economic problems, focusing on the process and consequences of economic activities and the development direction and trend of economic operation, without using any value standard to measure whether "what" is desirable.
Empirical research methods can be divided into mathematical empirical research and case empirical research;
1, mathematical empirical research refers to the use of mathematical measurement tools by researchers to analyze complex phenomena between social and economic systems. Mathematical measurement tools can eliminate endogenous variables, heteroscedasticity and multilinear problems, and grasp the internal relationship between responsible phenomena.
The disadvantage is that the mathematical empirical research requires very high data quality, data entry and process operation, and requires researchers to have corresponding high quality.
2. Case empirical research can be divided into case study and multi-case study. Case studies are true, in-depth and targeted, and multi-case studies are comprehensive and general.
Many times, multi-case studies are used to assist case studies and prevent the occurrence of generalized false facts. Researchers who use case studies should match each other according to the actual situation and the characteristics of the two research methods, and make more valuable analysis of the facts.
