The focus of academic and industry research on academic journals is on how to build a scientific evaluation system for academic journals and how to evaluate the role of academic journals in the enhancement of national scientific research strength at the macro level. The micro-function of academic journals themselves in academic evaluation has received little attention. As a matter of fact, from the evaluation of titles and awards of specific scientific research organizations to the construction of the three systems of philosophical and social sciences with Chinese characteristics and the construction of China's independent knowledge system, the effect and level of academic journals' academic evaluation function is relied on to a large extent. At present, the academic evaluation function of academic journals is the important value of the existence of academic journals, which determines the academic research ecology of the academic community to a certain extent, and then affects the academic status of China in the field of scientific research in the international arena. Based on this, first of all, this paper analyzes the research background and current situation of the academic evaluation function of academic journals, which is divided into initial evaluation and secondary evaluation according to the stage of evaluation of academic achievements, and the focus of academic evaluation should be different according to the different stages of evaluation. In the initial evaluation stage, the evaluation function of academic journals should be embodied in the overall evaluation of academic achievements, and the content of evaluation concerns the innovation of the selected topic, the standardization of the research, and the completeness of the argumentation. In the secondary evaluation stage, the evaluation focus of academic journals on academic achievements should be put on the academic innovativeness and social influence. Secondly, the current situation of academic evaluation dysfunctions of academic journals in China has been sorted out, and it is found that there are a large number of low-quality academic papers, frequent academic misconducts in academic journals, and the topic selection and content of academic papers published or reprinted are the same, etc. Finally, in view of the various dysfunctions, it is proposed that corresponding efforts should be made at three levels, namely, the macroscopic national institutions, the mesoscopic industry associations, and the microscopic academic journals themselves, in order to solve the problems. The innovation of this paper is to analyze the academic evaluation function of academic journals. Only by starting from the root of academic evaluation and controlling the quality of academic results can we fundamentally change the current situation of large quantity but low quality academic papers, thereby changing the atmosphere of China's scientific research, and promoting the production of high-quality scientific research results.
