Evidence from customs transaction data from 2000 to 2016 shows that processing firms propelled the export surge, utilizing the expanding domestic mate-rial varieties due to trade liberalization benefiting their upstream suppliers. The substitution of domestic materials for imported materials raised the domestic value-added ratio of the processing firms and the exports of green prod-ucts. A two-sector model rationalizes the empirical results. Trade policy liberalization, together with industrial policies, market scale, and synchronized global demand, contributed to China’s dominance.This paper is a product of the Development Research Group, Development Economics.
