随着全球气候变暖、能源紧张与环境污染等问题日益严峻,低碳汽车技术创新在全球范围内获得极大关注。本文以全球低碳汽车技术创新专利申请量排名前100名的领先组织为研究对象,通过专利数据挖掘,构建1992—2011年全球低碳汽车技术合作创新网络,分析全球低碳汽车技术合作创新网络特征及演化路径。研究结果表明,全球低碳汽车技术合作创新网络中行动者之间连接不紧密,信息的传播速度较慢;网络演化路径呈现网络密集度逐步提升,核心组织逐渐突显的趋势。
As the problems of global warming, energy shortage and environmental pollution are becoming more and more serious, the technological innovation of low-carbon vehicles has drawn great attention worldwide. In this paper, the leading organizations of the world’s top 100 low-carbon automotive technology patent applications are selected as the research objects. By means of patent data mining, a global innovation network of low-carbon automotive technology cooperation was constructed in 1992-2011. The global innovation network of low carbon automotive technology cooperation Features and evolutionary path. The research results show that there is a close connection between actors in the global cooperative innovation network of low-carbon automotive technology, and the information dissemination speed is slow. The network evolution path shows gradual enhancement of network density and gradual highlighting of core organizations.
