Technology Trade
研究了为什么一些国家进口更多研发密集型商品，发现国内投资、外商直接投资和知识产权质量有正向影响，而初级教育劳动力占比则降低进口。
This study addresses the question of why some countries import more research and development-intensive goods than others. Using a panel data set of 80 countries for the period 1970-1995, results indicate that domestic investment, foreign direct investment and the quality of intellectual property rights systems positively affect technology imports. However, the higher the percentage of the workforce with primary studies, the lower technology imports are. Moreover, intellectual property rights tend to reinforce the positive role played by foreign direct investments in importing technology while the ability of imitation reduces the effect of intellectual property rights.
