Abstract: Accelerating the innovation of clean technology has become one of the key ways to tackle climate change in China and the development of clean technologies is closely related to the research subject and innovation process. However, the existing literature focuses on the innovation process and results analysis of clean technology, and lacks the exploration of the guiding role of research and development. According to Chinese patent data from 2009 to 2014 to construct the network, this paper analyzes the characteristics and evolution of the research subjects of China's clean technology from the perspective of patent network, and through main path analysis method to explore the evolution of innovation. The results show that, in the I-U-R co-exist network, the scale of the network is increasing and the types of cooperation between I-U-R are equalized gradually. With Beijing being the core, supplemented by the Yangtze River and the Pearl River Delta, the influence of I-U-R spatial patterns gradually increases. The co-exist networks are mainly competitive, hence the government needs to enhance technology inductions and political guides on the research and development of clean technology. In the I-U-R evolutionary network, the cooperation patterns evolve from type of I-U to I-R so making use of independent research and development capabilities and influence of research institutes and enterprises is becoming a focal point.

摘要： 加快推动清洁技术创新发展已经成为我国应对气候变化问题的关键路径之一。清洁技术的发展，与研发主体和创新过程密切相关，然而现有文献大多集中于清洁技术的创新过程和结果分析，缺乏对创新源头——研发主体引导作用的探究。本文以产学研的研发主体为对象，基于专利网络的视角，进行中国清洁技术的研发主体特征及演化分析。本文根据2009-2014年间清洁技术领域公开的中国专利样本数据构建网络，通过网络结构分析探讨我国清洁技术领域的研发主体合作模式，并根据主路径分析方法探究我国产学研合作在清洁技术创新中的演进规律。研究发现：在研发主体共现网络中，网络规模呈逐年扩大的趋势，产学研合作的类型逐步均衡；在空间上以北京为核心、长江和珠江三角洲为两翼形成辐射带，且其影响力逐年扩大；产学研的合作模式以竞争状态为主，政府需要在现有技术研发态势的基础上强化技术诱导和政策指引。在产学研演进网络中，合作模式逐渐从高校-民营企业为主向研究院所和国企主体转移，发挥研究院所和企业的自主研发能力和影响力成为重点。
