This paper reviews China’s technological rise and assesses whether it poses a threat to the South Korean economy. In terms of comparative advantage between the two countries, many experts have long believed that China’s strength is low-cost labor and Korea’s is technology and capital. However, this has changed as China’s economy grows. Now China has enough capital to invest in its economy. Some scholars even argue that China has the potential to meet its “innovation imperative” and emerge as a driving force in innovation on a global level.1 This paper examines the Korea-China economic relationship from the innovation productivity perspective, organized into sections: briefly introducing the Korea- China economic relationship; describing the technological rise of China, based on recent data; developing the model to analyze the innovation productivity of China and report the estimation results; evaluating the concern of the South Korean semiconductor industry; and presenting conclusions.
