The study of GPN places great emphasis on the two issues. Based on the survey of Ningbo apparel industry, four key components of decent work in China apparel industry are discussed. The role of buyers in promoting decent work in suppliers can't be neglected. There are significant correlations between business type and some indicators of decent work. Though the majority of the apparel firms are engaging in processing, more and more firms are involved in marketing and branding. The upgrading trajectory of China apparel industry leads to the economic and social performances.展开更多

We analyze the transition of China's IC industry from a state-led integrated device manufacturers' model to deeper integration into the GPN. We also explore the technological sources, the upgrading dynamics as well as the positioning of different nodes of China's IC industry in the GPN. We conclude that the "East Asia model'" of gradual industrial upgrading might not apply anymore in the new era of GPN. High-technology industries can now be upgraded based on a parallel evolution model. Policy implications for China's high-technology industrial upgrading strategies are drawn from our analysis.展开更多
