摘要
通过对专利引用分析,构建了以石油天然气产业为核心的相关制造业技术流矩阵,展示了技术溢出的流向性,并测度了石油天然气产业上下游的技术溢出水平差异。结合MDS(多维尺度分析)技术溢出流向上分析了石油天然气上下游依托产业之间的相互关系。指出由于石油天然气上游行业其所处行业位置的外部效应并不能迅速带动周边行业的发展,其上下游创新策略应有所区别。
Based on analysis of patent citation,this paper establishes the technology flow matrices of the oil and gas and its related industry.Using the technology flow matrices,innovation and linkage of spillover between industries are discussed.Through multidimensional scaling analysis(MDS),the relationship between industries is displayed visually.It investigates that the oil and gas industry has a low level of technology spillover effect.As the same time,the upstream and downstream oil and gas industries have a di...
