Rural ethnic cultural archives have great potential in serving rural revitalization. Big data technology improves the application ability of big data by improving “processing ability”, and constructs a “big data + archives management” mechanism, which can give more convenient play to the value of archives. Starting from the problems existing in the construction of archives informatization talents and archives digitization technology system, this paper puts forward the information construction strategies of rural ethnic culture archives, such as accelerating the transformation and upgrading of rural ethnic cultural archives management, innovating the effective path of the development and utilization of rural ethnic cultural archives resources and so on.
