产业集聚、技术创新与城市经济动力

构建一个基于企业内生创新的具有正反馈效应的城市经济动力系统,旨在阐明产业集聚、技术创新与城市经济的关系。产业集聚的确有利于创新的产生,但绝非必然,甚至有时还会由于知识拥挤导致经济停滞。技术生命周期理论可以帮助我们解释产业集聚与创新集聚间的关系。城市提供创新激励,然而因吸收能力不同企业创新绩效也存在差异,这是城市经济差异的重要原因。

Agglomeration, Technological Innovation and Urban Economy

We built a dynamic system based on the endogenous innovation,just want to enclose the relationship between industry agglomeration,technological innovation and urban economy.Agglomeration do benefits the innovation but not certain,sometimes knowledge crowd will break up the agglomeration or the urban economy.The technology life-circle theory helps to interpret how agglomeration and innovation works.City provides innovation incentives,but there are differences owing to various absorption among firms,which is important reason why the city economy differs largely.
