he necessity of China's rare earth industry integration from the perspective of multiple constraints

China, as the largest rare earth reserve holder and producer of the world, supplies most of the world 'sdemand at a low price. Chinese rare earth producers have four kinds of constraints including quantity, profit, qualityand environment with long disordered mining, and malignant competition. Rare earth integration is a effectiveoption for the breakthrough of multiple constraints. This paper demonstrates the influences and pathways of rareearth integration on the multiple constraints.
