当前,能源紧张、环境污染、全球气候变暖等问题日益严峻,低碳汽车技术创新迫在眉睫。本文使用社会网络分析法,剖析1992—2011年间丰田汽车低碳技术合作创新中心网络特征与主题分布,丰田低碳汽车技术创新合作伙伴技术关联网络特征与演化过程。分析发现,网络行动者由于各自联结而拥有的关系权力的差异较大,相互间联结紧密程度处于中等水平,供应商在网络中占有重要地位。另外,丰田低碳汽车技术创新合作伙伴技术关联网络规模稳步增长,网络群聚效应逐渐突显。
At present, the problem of energy shortage, environment pollution, global wanning is increasingly serious, so low - carbon vehicle technology innovation is extremely urgent. Using social network analysis, this paper analyzes the characteristics and technology field of Toyota' s network of low - carbon vehicle technology collaborative innovation in 1992 - 2011, as well as the characteristics and evolution process of Toyota innovation partners' technology association network. The analysis found out that, based on the network actors' connection, the difference of relational power among them is relatively big, and their degree of closeness is on the medium level. Suppliers occupy an important position in the network. In addition, Toyota innovation partners' technology association network' s scale increases steadily and the network' s clustering effect becomes prominent.
