Abstract:

ICT industry plays a fundamental and leading role in the national economy. By analysis on the ICT industry’s correlation effects of the main countries using input-output table, the results show that ICT industry in major countries has the strongest correlation with their own. Compared with industries such as machinery and equipment, motor vehicles, ICT industry in major countries is more closely related to service industry, such as R&D and other business activities, wholesale and retail. At the same time, the study finds that the ICT industry of developed countries is highly competitive, with ICT industry at the middle and high end of the global value chain, and it is more technology-intensity than that of developing countries. To promote the development of ICT industry, it is suggested to strengthen the innovation of ICT technology, promote the integrated application of ICT, and pay attention to the development of industries with high correlation with ICT industry.
