In this paper, by analyzing Ingarden's phenomenological approach used in research on literary ontology, it suggests that Ingarden's phenomenology concept differs from Husserl's one in way of thinking, and the phenomenological approach he claims is only used to define the scope of literary research. The theory of intentionality is the theory that best reflects Ingarden's phenomenological approach, in Ingarden's discussion, the theory of intentionality expands its theoretical connotation; it is no longer regarded as a transcendental characteristic of the conscious subject, and the consciousness directionality and attributes of things, which are expanded into subjects, are extended beyond pure consciousness and goes deeply into the meaning composition of language. Ingarden's theory of intentionality not only illustrates the existence mode of literary works but also serves as the main thread running through the four layers of literary works, specifically explaining the intersubjectivity that makes communication between authors and readers, which is of great significance.
