Since 2001, the exports of foreign-invested enterprises (FIEs) have accounted for more than 50 percent of China’s total exports. As foreign capital occupies a high proportion of the total capital of FIEs, most FIEs’ capital gains are foreign factor income. Although these gains are calculated as a part of China’s GDP, they do not belong to China’s national income. To determine the real contribution of exports to China’s welfare, the present paper analyses the impact of exports on China’s national income using a non-competitive input–output model capturing processing trade. The results show that every US$1000 of China’s exports  generates US$506.8 of national income. The real contribution of exports to China’s welfare is much smaller than what we expected. This suggests that China should endeavor to improve the gains from international markets or find another engine to maintain its economic growth.
