The Multinational Firm
综述了国际贸易文献中关于跨国公司作用的最新进展，涵盖生产选址和垂直整合的激励因素，并比较了理论与实证研究的进展差异。
This article documents the recent advances in the international trade literature toward understanding the role of multinational firms in the conduct of international commerce. Over the past 10 years, we have developed a better understanding of the incentives firms face in their choice of production location, and we know more about the incentives that induce firms to vertically integrate. Furthermore, the theory literature has progressed from two-country models that cannot capture the richness of multinational firms’ activities to multicountry models that do. The empirics have advanced as well but at a slower pace. Progress has been slowed by the lack of comprehensive data and the difficulties of distinguishing between the various mechanisms proposed by theory.
