Cognitive similarity and the regional development of inventions: heterogeneity across renewable energy technologies
研究发现，可再生能源技术的发明依赖于区域内认知相似的知识，尤其在2010年后更明显，但不同技术存在差异：更成熟、更依赖科学知识、更具体且不那么激进的技术受益更多。
This paper finds that the development of inventions in renewable energy technologies seems to arise from cognitively similar knowledge located in the region, this being more the case in the last years (from 2010 onwards). However, despite this general conclusion, we observe a certain variability across technologies within the renewable energy realm. Our findings suggest that the role of knowledge obtained from local similar technologies depends on several characteristics: those renewable technologies that are more mature, use more scientific knowledge, and are more specific and less radical benefit more from the knowledge contained in cognitively similar technologies within the region.
