Abstract: This study systematically reviews research related to the scientific contributions of academic papers in the field of scientometrics, summarizes research methods and the latest progress, and aims to provide reference and guidance for subsequent research. By reviewing relevant domestic and international literature, this study first defines and analyzes the core concepts and connotations of the scientific contributions of academic papers. Subsequently, from a methodological perspective, it provides a detailed description and summary of the identification, classification, and intensity measurement of scientific contributions of academic papers. This study shows that the measurement of scientific contributions of academic papers is an emerging research field that is rapidly developing and requires further development and improvement. In the future, research can deepen the theoretical study of the mechanisms underlying the scientific contributions of papers and refine the measurement methods for fine-grained scientific contributions, such as theoretical contributions, methodological contributions and data contributions, and advance the application research of large language models in measuring the scientific contributions of papers.

Key words: Scientific contribution, Contribution identification, Contribution classification, Contribution intensity, Scientometrics
