Literature is a human study, so the content of literary works must involve the most basic social value relationship. Generally speaking, the relationship between man and nature, man and society, man and others, and man and himself. As a generalization and summary of literary phenomena, literary theory cannot avoid these problems in the study, and the study of these problems constitutes an important content of literary theory of value. The content of literary theory of value embodies the orientation and pursuit of literature in the spiritual dimension, which corresponds to the above relationship. It is manifested in the following dimensions: the ultimate concern at the ontological level and the human feelings at the real life level; The latter can be divided into social concern for the "ego" and personal concern for the "ego" (including self-care). On the theoretical level, the content level of literary theory of value corresponds to people's understanding of the role and function of literature; However, people's understanding and research on literature is consistent with people's current spiritual needs and social environment at that time. By studying the content of literary theory of value in a specific era, people can find out the enthusiasm of people in a period or era for literary creation and research, the degree of understanding of the essence and function of literature, and the corresponding literary value orientation and destination. In addition, through the study of the form and content of literary value, we can also find that literary theory, as the spiritual product of a specific era, reflects the social development and characteristics of the relevant era. In the complicated political and cultural environment of modern China, writers have made unremitting efforts to construct the value of literary theory. The establishment of value standard has become an important part of China's modern literary value theory. In the 1940s, the words "literary value" and "artistic value" frequently appeared in literary theories and critical articles. When analyzing literary works and literary phenomena, some theorists and critics try to distinguish and study the value of literature with intellectual concepts and categories, and try to establish a scientific literary axiology system with reference to discourse units of other disciplines. This is a positive expression of the consciousness of discipline construction in the development of literary theory, and of course it is also a literary theory. Generally speaking, there are two ways to produce the basic concepts or categories of a new discipline. One is to study the laws of things, summarize their essence and characteristics, and name things on this basis; Another method is through discourse transplantation, that is, naming and explaining new things or phenomena, that is, borrowing discourse units from other disciplines. Obviously, Jiang Tianzuo's research on literary theory of value adopts the latter method. Jiang's research on literary theory of value is related to the great role of literary discourse in social life in the 1940s. Because of its artistic power, literary works can often play a more instructive role than direct slogan propaganda. However, the influence and function of literary works, big or small, must go through the channels of communication and acceptance. The artistic quality of literary works directly affects the scope of communication and acceptance. Therefore, studying the characteristics and influence of literature and art will inevitably be put on the agenda of that era. Undoubtedly, the Chiang family clearly saw this and consciously regarded the "theory of value" of literature as "an important part of art theory"
