Do Stronger Intellectual Property Rights Increase International Technology Transfer? Empirical Evidence from U. S. Firm-Level Panel Data
利用1982-1999年间16个国家知识产权改革后的美国跨国公司数据，发现改革后子公司向母公司的技术使用费、研发支出和外国专利申请均增加，其中改革前专利使用多的公司增幅更大，技术使用费增幅超过30%。
This paper examines how technology transfer within U. S. multinational firms changes in response to a series of IPR reforms undertaken by sixteen countries over the 1982–1999 period. Analysis of detailed firm-level data reveals that royalty payments for technology transferred to affiliates increase at the time of reforms, as do affiliate R&D expenditures and total levels of foreign patent applications. Increases in royalty payments and R&D expenditures are concentrated among affiliates of parent companies that use U. S. patents extensively prior to reform and are therefore expected to value IPR reform most. For this set of affiliates, increases in royalty payments exceed 30 percent.
