We investigate the effects of China's economic growth on various sectors in the United States and other countries and regions, using a multi-region Global Trade Analysis Project (GTAP) model. The results indicate that all countries and regions, except South Korea and South Asian countries, would benefit from China's rapid economic growth. The welfare gain varies significantly across the countries and regions. Hong Kong and Taiwan would benefit the most from mainland China's economic growth in terms of per capita welfare gains. U.S. bilateral trade balance with China would improve in the sectors of grain and other primary agricultural products, but it would deteriorate in the sectors of textiles and high-tech manufacturing products.
