China's emergence as a key player in the global electronics industry has ignited concerns among its East Asian neighbors. Upper and middle-income economies fear that China's rise is hollowing out their electronics industrial base. Lower-income economies worry that they cannot compete with China's seemingly endless supply of cheap labor. In this chapter, we describe the forces behind China's rise in electronics, and we consider the implications for regional electronics trade and production patterns. Using a unique world electronics production data set, we investigate the upgrading trajectories of East Asian economies within the industry. Consistent with the theory of international production fragmentation, we find that Japan and the NIEs have a more sophisticated production mix than their lower-income neighbors. These latter economies, however, are upgrading their electronics industries more rapidly.
