Abstract: 【 Purpose/significance】 Analyzing and evaluating scientific data archiving policies can help standardize the process of sci⁃ entific data archiving in China, improve the efficiency of archiving, and thus promote the integrity management of the whole process of scientific research activities.【 Method/process】 This paper evaluates the degree of synergy among the policy objectives, the grouping of policy tools and the collaboration among policy areas in China′s scientific data archiving policies from three dimensions: policy ob⁃ jectives, policy tools and policy areas; and calculates the degree of consistency among the elements within the assessed policies.【 Re⁃ sult/conclusion】 The analysis finds that China′s scientific data archiving policy system basically achieves the synergy of multiple policy objectives and coordination of multiple policy areas, and the level of internal consistency of the policy is commendable, but there are problems such as insufficient attention to data archiving and over-reliance on environment-based policy tools. To help pro⁃ mote the construction of scientific research integrity and improve the data value-added mechanism, the data archiving process should be standardized to help, and the data service model should be innovated.【 Innovation/limitation】 A consistency evaluation strategy of scientific data archiving policy, including internal and external aspects, was explored that integrates the multi-dimensional character⁃ istics of policy. The evaluation system should further explore policy content characteristics, evaluation variables and their relationship.
