要了解可再生能源技术的全球知识动态，需要同时考虑技术层面和地理层面。本文评估了技术和地理上的遥远知识在可再生能源技术创新系统(TIS)未来知识发展中的相对重要性。利用全球可再生能源专利，我们将各国的吸收能力量化为技术创新系统中国内行为者之间知识扩散的知识积累程度。我们的结果表明，可再生能源技术创新倡议内的国际知识流动对于吸收能力较小的国家更为重要，而吸收能力较大的国家则更多地受益于源自其他技术创新倡议的国内知识。因此，在发展可再生能源技术时，每个国家在全球技术发展方面都面临着独特的机会和限制。这些发现导致了针对不同国家发展可再生能源技术的具体政策影响。
ABSTRACT Understanding the global knowledge dynamics of renewable energy technologies requires consideration of both technological and geographical dimensions. This paper assesses the relative importance of technological and geographical distant knowledge in the future knowledge development of technological innovation systems (TIS) of renewables. Using global renewable energy patents, we quantify the absorptive capacity of countries as the degree of knowledge accumulation in the knowledge diffusion between domestic actors in a TIS. Our results show that international knowledge flows within a renewable energy TIS are more important for countries with smaller absorptive capacity, whereas countries with larger absorptive capacity benefit more from domestic knowledge originating in other TISs. Consequently, each country faces unique opportunities and constraints with respect to global technological developments when developing renewable energy technologies. These findings lead to policy implications that are specific to developing renewable energy technologies in different countries.
