First of all, theoretical innovation means that we put forward new ideas in the paper and discuss their rationality in the paper.
The second is practical innovation, which is the innovation of research methods and research objects. The innovation of research methods is to cross-analyze problems with other disciplines and provide diversified ideas for the study of problems. The innovation of the research object is to study the problem, extract a point, and use the knowledge learned to systematically analyze this point. This problem can be deepened.
Finally, applied innovation is to apply a knowledge theory to a new field.
