From the perspective of the sociology of news production，we analyze the current development of data journalism in China. The research finds that data journalism practitioners are becoming more diverse，but data journalism professionals are still lacking. The data sources used by data journalism are still relatively complex and the quality of open data from the government is still insufficient friendly. The production field of data journalism is affected by economic，political，technical and time factors. The business model of data journalism is not clear，but there have been attempts in consulting，products，and customization. In general，the differentiation of the Chinese data journalism industry format and the internal integration of the institution coexist. With the advent of the 5G era，data journalism will gain greater opportunities for development. It will also require the media to assume greater responsibilities，be a good journalist in the data era，and open a breakthrough in the transmission of ecological change.
