The implementation of the national cultural digitization strategy is an important initiative to promote the construction of a country with a strong socialist culture, while the construction of high-quality digital talents is an important foundation and key support for the construction of a strong educational and socialist cultural country. Based on the development of data journalism and the current situation of talent cultivation, combining the competency theory and model, through questionnaire survey and empirical research, we construct a set of multi-level, fine-grained data journalism talent job competency quantitative rating model, according to the index system of the model, data journalism talent cultivation needs to be carried out from the three aspects of personal traits, knowledge literacy, and technical ability. The study found that data news talent training should focus on data news talent training elements and implement talent competency enhancement; practice the national digital development strategy and actively serve the national news and public opinion propaganda; and dock the international data news communication track and vigorously construct international communication channels.
