摘要

Battery electric vehicles (BEVs) have been in the fourth wave of the low emission vehicle development since 2006. Moreover, the BEV technology diffusion is beyond national boundaries due to the changes in the innovation mode and product characteristics. The paper adopts priority patent applications and international patent families to map the BEV transnational technology diffusion from the perspective of global technology innovation (GTI). Our study finds the sources and recipients of BEV technology are concentrated in a few countries or regions, while the transnational technology diffusion is uneven, especially in the core group. The key drivers of technology diffusion are the innovation capacity of countries and the scale of countries? market demand for BEV technology. Our findings enrich the literature on transnational technology diffusion and help policy-makers or company managers better understanding of why some countries may achieve success while others made little progress in the similar context of promoting BEV development. ? 2021 Elsevier Ltd.

BEV技术的市场需求。我们的调查结果丰富了跨国技术扩散的文献,并帮助政策制定者或公司管理人员更好地了解为什么有些国家可能会取得成功,而其他国家则在促进BEV发展的类似背景下取得了很少的进展。还是2021 elestvier有限公司保留所有权利。
