China's outward FDI has been increasing recently, as the country's policies over industrialization and national security change. Using financial data of 244 Chinese enterprises, this study empirically investigates the patterns and determinants of China's outward FDI from 2001 to 2008 for its seven major destinations. Tobit and multiple regression analyses indicate that early Chinese FDI in 2001 and 2002 is concentrated in the labor-intensive industries in Asia, like those of early Japanese FDI in the early 1970s as well as those of Korean FDI in 1990s. The results also indicate that non-production oriented manufacturers invested in North America, in order to seek for market cultivation, technological advance, R&D skills, and name brands. We also found that the central state-owned enterprises are the key FDI players in the continents with locational disadvantages 展开更多

This paper provides indicators on the length, location, and linkages of global value chains (GVCs) across BRICS countries. These indicators are calculated at the country level using the WIOD database. We find that, as Chinese GVCs lengthen, production stages are increasingly concentrated in China. At the same time, the "upstreamness" of Chinese production stages in GVCs is also increasing. Compared with China, other BRICS countries' positions in GVCs remain relatively unchanged. Since 2000, a new phenomenon has emerged; i.e., some service sectors within the BRICS have begun to participate in GVCs. 展开更多
