Abstract: In the backdrop of the digital era, the digital exploitation and three-dimensional application of red cultural resources by means of digital technologies can enhance the efficacy of red culture in serving the construction of mainstream ideology. Currently, however, the digital construction of red cultural resources is still confronted with realistic predicaments, such as inadequate development intensity, low utilization efficiency, and suboptimal dissemination effect. The digital construction of red cultural resources should take meeting the cultural demands of people in the digital age as the starting point. Through measures like developing digital cultural and creative products of red culture, intensifying the construction of digital sharing platforms for red culture, and optimizing the digital education paths of red culture, the integration path of red cultural resources and digital technologies should be explored to enhance the educational effectiveness of digital red cultural resources.
