In the archival field, "National Archival Resources" has become a term of increasing interest. The study delves into the concept, the valuation of "National Archival Resources" and the differentiation from "State-Owned Archival Resources." After synthesizing the prevailing scholarly views on the value and preservation of national archival resources, the paper critiques the limitations inherent in ownership-based criteria for defining "National Archival Resources," and clearly points out the necessity of clarifying and refining the explication of "preservation value to the state and society." In light of the exigencies of national security, law enforcement, and archival governance, the paper articulates the practical significance of the concept and its value elucidation, and unveils the deep-seated connotation of the preservation value of national archival resources through the lenses of national security, diverse social interests, historical documentation, and cultural inheritance. Subsequently, the paper explores the expression of the concept of "National Archival Resources" and makes a comparative analysis with "State-Owned Archival Resources"with only one word difference，so as to enrich the discourse on the conceptual understanding of national archival resources.
