演講摘要 : This paper develops a Heckscher--Ohlin model containing heterogeneous producers with dynamic entry, exit and export decisions, and an endogenous market structure. Because of the endogenous markups, and contrary to the conventional export-driven mechanism, competition increases aggregate productivity by reallocating factors and changing the entry and exit decisions of producers. Therefore, trade can have a profound impact on variables in import-competing sectors rather than exporting sectors. This more accurately reflects our intuitive expectations and empirical observation. A Heckscher--Ohlin model with homogeneous producers and perfect competition is then a special case of this model, which offers the possibility for further theoretical extension into fields employing the traditional Heckscher--Ohlin model.
