Evaluating differences in technological activity between transnational and domestic firms in Latin America
比较拉丁美洲跨国公司与国内企业在增长、盈利和技术活动上的差异，发现两者在传统绩效和新技术的实施上差别不大，但技术来源不同：国内企业更依赖内部创新，而外资企业更多从外部获取技术。
Abstract This study uses a sample of Latin American firms from four areas to compare the performance and technological activity of transnational to domestic firms. After accounting for scale, age and location of firm, we find few differences in either traditional methods of growth or profitability or in implementation of new technology embodied in processes or products. There are important differences in the sources of new technology. Domestic firms have a relatively higher level of internal innovative activity, whereas foreign firms rely more heavily (but not exclusively) on sources external to the subsidiary.
