China's intellectual property protection strength and its evaluation - based on the accession to TRIPS Agreement (Agreement On Trade-related Aspects of Intellectual Property Rights)

This paper builds China's intellectual property protection strength from the aspects of intellectual property legislation protection strength and law enforcement protection strength, and calculates by using the actual data from 1985 to 2010. The results show that China's intellectual property protection strength has always been enhanced, and Chow test shows that the structural breakpoints appeared in China's intellectual property protection strength in 2001(when China joined TRIPS Agreement). The further Granger causality test shows that the economic development level and technological innovation ability are the factors promoting China's intellectual property protection strength, which, however, has not effectively promoted economic development and technological innovation ability due to the impact of the overall economic development level.
