中美产业技术创新能力比较研究——以装备制造业和信息通信产业为例

Based on the IPC-NAICS identification system from patent category to industry classification, and taking equipment manufacturing industry and information and communications industry as case, this paper compares and analyzes the differences in technological innovation capabilities between China and the United States in equipment manufacturing industry and information and communications industry. The study shows that: (1) The industry technological innovation capability of China's equipment manufacturing has rapidly improved, but it is significantly behind the United States in terms of the overall technological innovation capability of the equipment manufacturing industry and the technological innovation capabilities of the four sub-sectors of mechanical equipment, medical equipment, transportation equipment and electrical equipment. (2) The industry technological innovation capability of China's information and communications has caught up with the United States rapidly, especially in the communications equipment industry. However, the gap between China and the United States in the three sub-industries of computer, semiconductor and instrument measurement is still significant.
