U.S.-China Technological Rivalry and Its Implications for Korea

Recent developments in advanced technology are changing the concept of hegemonic competition. The key feature of technologies in the 4th Industrial Revolution is dual-use. Emerging technologies such as 5G, AI, big data, robotics, aerospace, supercomputers, and quantum computer-related technologies can be used for both civilian and military purposes. The more you invest in the development of advanced technologies, the closer you will be to economic and military hegemony. Therefore, it is no wonder that the U.S. harbors great concerns facing the rise of China in these advanced technologies. To estimate and compare the innovation productivity of the U.S. and that of China, this study constructs a structural estimation model in which each country produces international patents using R&D expenditures and R&D researchers. Empirical results have presented novel findings indicating that China's innovation productivity has surpassed that of the U.S. since 2015. At the same time we can observe that the U.S. has the world’s largest intellectual property surplus and keeps expanding it, while China's intellectual property deficit has been growing every year. Given the two contradictory facts - China's high innovation productivity and low intellectual property balance - we can conclude that China is strong at "innovation" but weak at "invention." Knowing this, the U.S. eventually began to target this vulnerability. This is the U.S.' Tech-Decoupling strategy. To achieve U.S.-China tech decoupling, the U.S. has been strengthening trade and investment sanctions against China. In specific, the U.S. has been utilizing the Export Control Reform Act (ECRA), Section 889 of the 2019 National Defense Authority Act, and the Foreign Investment Risk Review Modernization Act (FIRRMA). In return, China is responding to the U.S. sanctions with the new "Long March" strategy rather than a tit-for-tat strategy. In other words, China has been setting long-term aims and responding to the U.S. sanctions by improving institutional arrangements, refining industrial policies, and developing its own technologies such as "Dual-circulation strategy" and "New Infrastructure Plan."
