Study on Methodology of Comparative Safety Science

To perfect the discipline system of comparative safety science,guide and promote comparative safety science research,the comparative safety science was studied from the methodo logical point of view.Combining with the methodology of comparative theory and the methodology of safety science,the foundation and principles of the methodology of comparative safety science were determined.The research methods of comparative safety science were summarized,including general methods of comparative research and methods introduced from other relevant disciplines,such as the structure and function analysis,statistical analysis method and factor analysis.Starting with the subject characteristics of comparative safety science,five basic characteristics of methodology of comparative safety science were refined.And a four-dimensional structure system of the methodology of comparative safety science was founded.By synthesizing relevant data,the general procedures of the comparative safety science research were also established,and,on this basis,a paradigm system was established.The comparative safety science has its unique methodology,it guides the research work of comparative safety science.
