R&D Efficiency in High-Tech Firms in China
Using firm-level data from Changzhou, one of the representative prefectural cities in the Yangzi River Delta in China, we investigate the performances of both internal and external R&D in high-tech firms. We find that, on average, high-tech firms with more internal R&D expenditure apply for more patents in terms of both the total number of patents and the number of invention patents. Internal R&D is the most efficient in foreign firms, followed by private firms and then followed by SOEs (state-owned enterprises). These findings highlight the importance of privatizing high-tech firms in China if the Chinese government intends to accelerate industrial upgrading and convert the pattern of “Made in China” into “Created in China.”
