5 Conclusion
This paper mainly analyzes how IPR influence recorded music sales of 26 OECD
nations from 2000 to 2007. The author also introduces other independent
variables such as per capita GDP, employment rate and R&D, population and
economic openness. Different from previous studies, the author adopts two way
fixed effects method, Arellano-Bond dynamic panel-data estimation and dynamic
panel-data estimation, one-step difference GMM by use of Stata 10.0. The
findings are as followings: IPRs protection exerts positive effect on recorded
music sales,the influencing coefficient is at the range of 0.815 to 0.915 on the
sale of recorded music. Meanwhile, economic openness also has positive influence.
Inferred from the case of 26 OECD countries, it is necessary to reinforce
intellectual property rights protection. From the macro aspect, it is necessary to
better intellectual property legislation for one country. Related government
organizations can handle the illegal behaviors by use of severe punishment or
high fine. From the micro aspect, it is necessary for individual to enhance the
consciousness of property rights protection.
This paper mainly adopts economic variables such as per capita GDP,
economic openness. It is a pity to omit some political or institutional data.
Meanwhile the study range is just within OECD, it is an expectation to combine
developed countries and developing countries together.
