Learning-by-Producing and the Geographic Links Between Invention and Production: Experience from the Second Industrial Revolution
研究了1870-1910年间美国新兴和成熟产业中“边生产边学习”对发明活动的地理影响，发现生产区域转移并未带来相应发明增长，发明活动更多取决于高级技术人才的分布。
This article investigates the impact of “learning-by-producing” on inventive activity. From 1870 to 1910, in both emerging (electrical equipment and supplies) and maturing (shoes and textiles) industries, the geographic association between invention and production was rather weak. Regional shifts in production did not lead to corresponding increases in invention. The location of inventive activity tended to mirror that of individuals with advanced technical skills appropriate to each industry. Consequently, scholars may have overemphasized the importance of learning-by-producing in accounting for geographic differences in inventive activity, and underestimated the significance of technical skills amongst the population.
