This paper focuses on the multiple dimensions of market-based reforms and their impacts on firms' product innovation performance in China, the largest emerging country in the world. By analyzing a data set with more than one-half-million observations on firms during China's economic transition during the period 2005-2007, we find that the progress of market-based reforms and the degree to which different dimensions of market-based reforms are conducted simultaneously, referred to as synchronization, have a positive effect on firms' product innovation. We also find that firms with higher absorptive capacity benefit more from market-based reforms and the synchronization of different dimensions of market-based reforms. (C) 2015 Elsevier Inc.
