The first indicator system is good. The existing index system helps researchers to define the research objectives and scope, and provides a clear direction and framework for research. By constructing the index system, we can classify and divide all aspects of the research object, so as to understand the characteristics and laws of the research object more comprehensively and systematically. The index system can also provide quantitative basis and methods for research, which is convenient for data analysis and comparison of research results. This index system is widely used in different fields and scenarios. For example, in the economic field, the index system can be used to evaluate the operating conditions and market competitiveness of enterprises, in the environmental field, it can be used to monitor and evaluate environmental quality, and in the educational field, it can be used to evaluate students' academic performance and educational quality.
