摘　　要：基于国际垂直分工的理论视野,界定了单体企业的适度规模经济和企业集团总体的最适规模经济等概念范畴的内涵与外延,并结合垂直范围经济和聚集经济等相关概念,从技术经济角度给出了企业集团适度规模经济的模型框架和测度方法,揭示了企业集团在地域上的合理规模即集聚程度与集聚效益之间的倒U字形钟形关系。利用该分析框架,提出了在国际垂直分工视野下,生物医药和专用设备制造等重点行业实现企业集团适度规模经济战略选择的关键在于利用企业集团的集聚经济优势和范围经济优势,并通过产品细分的差别化定位,实现大型企业集团对中小企业集群的策略性替代。Based on the related theories of international vertical labor division,the paper first gives some definitions and contents such as the optimum scale of economy of single firm and firm groups,then sets a theory model and presents a method to measure the optimum economy of scale of firm groups on the view of technical economy based on the concepts of economy of scope and agglomeration economy,and reveals that there is an inverted U bell-shaped relationship between the enterprise group in geographical extent of a reasonable size and the agglomeration benefits at the suit concentration,and finally,we talk about such questions as the optimum choices of optimum scale of firm groups,especially the strategy choice of small and medium-sized medical and equipment enterprises to be substituted for giant firm groups under the condition of international vertical division driven by multinational companies.
