Do Industrial Policies Lead to Excess Capacity? Empirical Evidence from China
Joint with Zonglai Kou and Xueyue Liu, Fudan Journal (Social Sciences Edition), 59(5), 2017: 148-161.
Industrial policies on capital investment in China come in two types—those that incentivize firms to purchase more equipment, and those that discourage investment in inefficient, outdated, or polluting equipment by restricting firms' equipment choices or even mandating divestment of such existing equipment. The encouraging policies effectively induce more investment and lead to rising excess capacity, especially in state-owned firms. However, the restrictive policies have little effect on reducing excess capacity.
