Localization of Knowledge and the Mobility of Engineers in Regional Networks
通过分析半导体专利引用和发明人跨公司流动数据，发现知识溢出本地化程度因区域而异（尤其是硅谷），且工程师流动促进了本地知识转移。
Knowledge, once generated, spills only imperfectly among firms and nations. We posit that since institutions and labor networks vary by region, there should be regional variations in the localization of spillovers. We investigate the relationship between the mobility of major patent holders and the localization of technological knowledge through the analysis of patent citations of important semiconductor innovations. We find that knowledge localization is specific to only certain regions (particularly Silicon Valley) and that the degree of localization varies across regions. By analyzing data on the interfirm mobility of patent holders, we empirically show that the interfirm mobility of engineers influences the local transfer of knowledge. The flow of knowledge is embedded in regional labor networks.
