Abstract: Against the backdrop of China's systematic layout of the data infrastructure system, the formation and realization paths of the value of local chronicle data elements are further clarified. Based on the relevant research findings related to the development and utilization of local chronicles and the realization of data element value, this paper first articulates the connotation and characteristics of local chronicle data elements, pointing out that local chronicle data elements have the following characteristics: non-excludability of public culture, synergism of data aggregation, derivativeness of knowledge recombination, and complexity of property rights management. Secondly, it constructs a local chronicle data element value chain that covers the entire process from data collection and aggregation to data service utilization. Finally, it proposes strategies for the realization of the value of local chronicle data elements from four aspects, including top-level design, unified registration mechanism, product system construction, and the construction of a trustworthy data space. The research findings are conducive to promoting the expansion of China's local chronicle work from compilation to data production and application. They also help to stimulate the innovative vitality of local chronicles and enable them to play a greater role in the construction of Digital China, especially in the strategy of cultural digitalization.
