本文考察了垄断力量如何在不受规模效应影响的情况下影响经济一体化与经济增长之间的关系。在两国贸易模型中，生产率增长是由企业层面对过程创新的投资产生的，而经济活动的地点取决于相对市场规模、贸易成本和不完全的知识扩散。均衡的特征是制造业的部分集中和创新的完全集中在更大的国家。经济一体化程度的提高提高了制造业在更大国家的集中度，当垄断力量强大时，会导致产品种类减少，生产率加速增长，国民福利增加。然而，由于垄断力量较弱，它增加了产品的多样性，抑制了生产率的增长，但可能有利于或损害福利。
This paper considers how monopoly power affects the relationship between economic integration and economic growth that is not biased by a scale effect. In a two‐country model of trade, productivity growth is generated by firm‐level investment in process innovation, and the location of economic activity is determined by relative market size, trade costs and imperfect knowledge diffusion. Equilibrium features the partial concentration of manufacturing and the full concentration of innovation in the larger country. Increased economic integration raises the concentration of manufacturing in the larger country, and when monopoly power is strong, leads to decreased product variety, accelerated productivity growth and greater national welfare. With weak monopoly power, however, it raises product variety and dampens productivity growth, but may benefit or hurt welfare.
