Knowledge Spillovers in Europe: A Patent Citations Analysis
通过分析欧洲地区间的专利引用模式，发现知识流动存在重要障碍：引用更常发生在同一国家、地理邻近、语言相同或产业技术关联紧密的地区之间。
This paper addresses the pattern of knowledge flows as indicated by patent citations between European regions. Our findings support the hypothesis that there are important barriers to knowledge flows in Europe. Patent citations occur more often between regions which belong to the same country and which are in geographical proximity. Furthermore, patent citations are industry specific and occur most often between regions that are specialised in industrial sectors with specific technological linkages between them. Patent citations are also more frequent when the citing region belongs to the same linguistic group as the cited region.
