中文摘要：

后经济危机时代，新能源汽车作为中国战略新兴产业之一，在加快转变经济增长方式、振兴中国传统汽车制造业上扮演着极其重要的角色。本文通过对该领域整体发明专利和产学研联名专利的对比分析，得出结论：中国新能源汽车领域最初的研究主体是高校及科研院所．随着该技术的产业化、市场化，有更多的企业加入到新能源汽车技术的研发之中；日本和美国的公司表现出较强的研发能力．中国企业研发能力有限，企业与高校的合作在加强，与科研院所的合作力度降低：企业自主研发与产学研联合研发所侧重的技术领域有所不同，高校和科研机构的技术热点也存在差异。

英文摘要：

After the era of economic crisis, as one of the national strategic emerging industries, the new energy automobile industry plays a very important role in accelerating the transition of economic growth mode and developing the traditional automotive industry. This paper compares the total invention patents with the joint invention patents by university and company. We find that universities and research institutes started R＆D activities in the field earliest. With the industrialization and marketization of the technology, more and more firms join in. Japanese and American firms show stronger R＆D capacity than Chinese firms, while the Chinese firms and universities tend to have more cooperation in applying patents. There is a difference in technology focus between the total and joint invention patents.
