摘　　要：报酬递增是技术集聚形成的一种重要机制,这种机制可以通过空间经济学的模型予以严格的解释。经典的迪克西特与斯蒂格利茨模型(DS模型)有着企业数量趋于无限大的假定,杨小凯与海吉拉模型(YH模型)放弃了这个假定但没有考虑不同部门之间的工资差别。本文对YH模型进行了拓展,建立了一个包含部门工资差别的报酬递增模型,具有更强的现实解释力。Technological agglomeration refers to the phenomenon that the newest technological developments（such as new products,new process techniques） in some industrial field are often realized at one or a few small geographical areas.It differs from industrial cluster at the point of whether the area has worldwide or countrywide technological advantage.Increasing return to scale is an important forming mechanism of technological agglomeration.This mechanism can be strictly expounded by the model of economics of space. The Dixit-Stiglitz model has the premise that the quantity of firms is infinite.The Yang-Heijdra model abandoned that premise,but did not covered the wage difference of different production sector.This paper comes up with a monopolistic competition model of increasing return to scale,which overcomes the shortcome of YangHeijdra model and can give a more accredited explanation of the reality.
