This study uses an econometric approach to investigate the role of IPR protection on renewable energy adoption using panel data of 102 countries at five-year intervals over the period 1990–2005. The Ginarte-Park index is used as a measure of the strength of intellectual property protection while the adoption of renewable energy is measured by the share of renewable energy in total final energy use. The results reveal that the level of intellectual property rights protection and reform of the intellectual property rights regime do not have significant impact on renewable energy adoption, suggesting that IPR protection is not a cause for concern in the global quest for clean energy transition. On the contrary, we find that trade openness has a stronger influence in the transition to clean energy. Based on the findings of the study, we conclude that IPR protection does not influence renewable energy adoption except in high R&D countries; rather policy makers should concentrate efforts on economic factors, such as trade openness, that drive the adoption of renewable energy technologies.

知识产权保护是否构成可再生能源的障碍？经济分析

本研究使用计量经济学方法，使用 1990-2005 年期间 102 个国家的面板数据，以五年为间隔，调查知识产权保护对可再生能源采用的作用。Ginarte-Park 指数用于衡量知识产权保护的强度，而可再生能源的采用则通过可再生能源在最终能源使用总量中的份额来衡量。结果表明，知识产权保护水平和知识产权制度改革对可再生能源的采用没有显着影响，这表明知识产权保护不是全球寻求清洁能源转型的关注点。相反，我们发现贸易开放对向清洁能源转型的影响更大。根据研究结果，我们得出结论，除了高研发国家，知识产权保护不会影响可再生能源的采用；相反，政策制定者应该将精力集中在推动采用可再生能源技术的经济因素上，例如贸易开放。
