Almost all papers must have data to support the core of the paper. Without data, it will be empty. The analysis part of the paper is inseparable from three elements: the first is the theoretical basis. The research of almost all disciplines is based on a specific analytical framework and theory. The second is data (or cases). Data is the support of argument, and data is the raw material of scientific analysis. It can even be said that with good data support, the research itself has been half successful. The integrity and accuracy of the research materials are also directly related to the validity and reliability of the research results. The third is the method. Narrow method refers to the method of how to process data. Generalized methods generally refer to empirical analysis methods based on practical phenomena or normative analysis methods based on theoretical viewpoints.
