20世纪80年代以来,借助新贸易理论一般均衡模型对跨国公司的研究不断推进,从强调要素禀赋差异的垂直型跨国公司模型和强调临近—集中权衡的水平型跨国公司模型,到试图将两者综合起来的KK模型,再到引入多国、多要素对一般均衡模型的扩展研究,洞察了国家、产业、企业层面影响跨国公司结构的决定因素,在国际经济理论领域产生了深远影响。而实践中垂直型和水平型跨国公司以何为主,相关实证研究结论却莫衷一是。从研究范式看,基于新贸易理论的跨国公司一般均衡模型没能完全超越OIL框架,解释非一体化的组织结构、发展中跨国公司的兴起、企业异质性的作用,是其需要突破的研究方向。
Since the 1980s, the study of transnational corporations has been continuously promoted with the help of the new trade theory general equilibrium model, from vertical multinational corporation models emphasizing differences in factor endowment to horizontal multinational corporation models emphasizing near-concentration tradeoffs, The integrated KK model, followed by the introduction of multi-country and multi-factor extensions to the general equilibrium model, provides insight into the determinants of the multinational corporation structure at the national, industrial, and corporate levels, and has a profound influence in the field of international economic theory. In practice, vertical and horizontal MNCs are mainly based on what they are and the empirical research conclusions are inconclusive. Judging from the research paradigm, the general equilibrium model of multinational companies based on the new trade theory fails to completely surpass the OIL framework, explaining the role of non-integrated organizational structure, the rise of multinational corporations in development, and the heterogeneity of firms. direction.
