Industry Determinants and "Differences" in U.S. Intrafirm and Arms-Length Exports
利用美国联邦贸易委员会249个制造业的机密数据，检验内部化理论能否区分公司内部出口与独立出口，结果发现行业层面的支持较弱。
Internalization has been held high in the literature on foreign direct investment and intrafirm trade. This paper empirically examines the strength of this theory in distinguishing U.S. intrafirm exports from its arms-length counterpart. Using dummy variable specifications, it estimates differences in the relationship between traditional trade variables and the two different types of export trade across 249 manufacturing industries. It has the advantage of using confidential line-of-business data from the U.S. Federal Trade Commission data bank. At the industry level, results suggest weak support for internalization as an effective discriminating model of intrafirm exports. Copyright 1990 by MIT Press.
