Technology Transfer and Domestic Innovation: Evidence From the High-speed Rail Sector in China
AbstractThis paper investigates China's high-speed railway (HSR) technology introduction to show how it spurs innovation in local regions and in relevant industries. The large-scale technology introduction, covering specific technology categories and directly benefiting railway-related firms from various cities, enables us to specifically depict how foreign technology is digested and spurs follow-up innovation in and out of directly receiving firms. We find that technology transfer generates significant localized spillovers to nearby firms not only in terms more patents, but also in terms of higher productivity and revenue growth. Moreover, technology similarity plays a dominant role in explaining the knowledge spillover both at the firm level and the aggregate level, which indicates the importance of absorptive capacity in digesting foreign technologies.
Tort Reform and Innovation
AbstractCurrent academic and policy debates focus on the impact of tort reforms on physicians’ behavior and medical costs. This paper examines whether these reforms also affect incentives to develop new technologies. We find that, on average, laws that limit the liability exposure of healthcare providers are associated with a significant reduction in medical device patenting and that the effect is predominantly driven by innovators located in the states passing the reforms. Tort reforms have the strongest impact in medical fields in which the probability of facing a malpractice claim is the largest, and they do not seem to affect the amount of new technologies of the highest and lowest quality. Our results underscore the importance of considering dynamic effects in the economic analysis of tort laws.
Innovation and Economic Growth: Evidence From China
AbstractThis paper studies the impact of innovation on economic growth (per capita GDP growth) at the city level in China based on a panel dataset from 1995 to 2015. We use granted patents (invention, utility model, and design) and trademarks to firms as measures of innovation. We first match national patent and trademark data with firm registry database and then aggregate them into city level. We find that the innovation is positively associated with economic growth no matter whether we use invention patents, utility model patent, design patent, or trademarks as a measure of innovation.
