At the invitation of our institute, Prof. Qiao Xiaochun from Peking University gave an academic report entitled “How to do scientific social science research?” on the afternoon of November 27th. Associate Dean Pan Dan presided over the academic report meeting. Teachers and students from the School of Information Management, the School of Finance, the School of Statistics, the Institute of Ecological Economics, and the School of Economics listened to this academic report. 
Professor Qiao started from the process of scientific research-----logical methods and technical methods, and introduced in detail the level of social science research methods and the content system of social science research methods. The report divides the content system of scientific research methods into four. The levels are general methodologyresearch design and research methods (or social science research methods, social surveys and research methods, etc.); general technical methodsquantitative methods include statistical principles, sample survey methods, linear regression models, Classification data analysis, survival analysis, multivariate statistics, path analysis, structural equation modeling, etc.; qualitative methods include case analysis, grounded theory, focus group discussion, etc.; specific technical methodseconometrics, measurement psychology, measurement sociology, etc. Professor Qiao pointed out that each method can only target a certain type of specific data, and there is a limit to one method. Learning must be systematic, avoiding fragmentation and leapfrogging. Then Professor Qiao introduced the characteristics of various research methods or models such as survival analysis, structural equation model, Markov chain model, computer simulation, Monte Carlo method and Bayesian method. Professor Qiao pointed out that the model follows the data. With what kind of data, choose the model corresponding to it. The misuse of the model is a big problem at present. Therefore, the learning model must first learn the data type and data structure. As an application statistician, you must also master the necessary statistical analysis software, but you must never follow the software to learn the method. The most ideal method of social science research is to combine quantitative research methods with qualitative research methods. 
After the report, Professor Qiao also conducted on-the-spot interaction with professors and graduate students on how to rationally select variables and how to establish interdisciplinary research teams.
