文献来源 Industrial Internet (Innet): This study uses the word frequency of “industrial Internet” in the annual reports of the listed companies to measure enterprises’ actual application level of the industrial Internet. First, we combine the Industrial Internet Definition and Terminology Report released by the Industrial Internet Alliance and the policy documents of the Ministry of Industry and Information Technology on the industrial Internet to build a lexicon of corporate “industrial Internet” usage. Second, we extract the management, discussion, and analysis contents from the annual reports of the listed companies, and counted the number of keywords related to the industrial Internet in these reports. Finally, we measured the proportion of the number of keywords related to the industrial Internet out of the total frequency. Guo, X., Liu, N. (2024).
