摘要
本地市场效应是新贸易理论中的一个中心概念。作者回顾了它的起源背景,并解说了从最新研究成果所看出的问题,探讨了将来的进一步发展方向。早期的国际贸易和区域科学的学者们从不同的角度出发,使用各种不同的定义描述了大市场和大需求带来的制造业集聚效应在两国构成的经济空间里,大国的制造业企业份额高于其人口比例,大国是制造业产品的净出口国,其工资较高。在得出这些结果的模型里,大家都假定了单个生产要素——不可移动的劳动力。这些概念的片面性影响了对本地市场效应的本质认识。后来,通过建立两个生产要素(不可移动的劳动力和可以移动的资本)的模型,学者们把这些概念统一在一个框架里。可是最新的研究成果有些意外。如果考虑多国构成的经济空间,或者采用更为一般的效用函数,会发现之前的很多结果都要修改。
This paper reviews the development of a key concept in new trade theory—home market effect(HME).After providing the origin and background of the HME,the author explains some problems in this field from the frontier results and explores some directions for future work.Based on different viewpoints,earlier scholars from international trade and regional science use various definitions to describe the agglomeration force of the manufacturing sector originating from the large demand in a large market:in a two-country space,(i)the firm share in the larger country is more than proportionate,(ii)the larger country is a net exporter,and(iii)the wage rate in the larger country is higher.The models deriving these results usually assume a unique production factor—immobile labor.Because of the limited flexibility,these definitions fail to capture the essence of the HME.They are unified later via models with two production factors—immobile labor and mobile capital.Latest results are surprising.If we consider a space of multiple countries,or apply a more general utility function,many results on the HME need to be revised.
