We study whether the 2002 deregulation and vertical unbundling of the Chinese electricity sector has boosted productivity in the generation segment of the industry. Controlling explicitly for sources of price-heterogeneity across firms and for firm-fixed effects, we find deregulation to be associated with a reduction in labor input and material use of 6 and 4 percent, respectively. This effect only appears two years after the reforms, is robust to alternative ways of identifying restructured firms, and to the nonrandom selection of restructured firms using a matching estimator. Input use of new state-owned firms that start operations two years into the reform period does not differ significantly anymore from input use of private sector entrants.
