Knowledge Spillover and Regional Innovation Performance Based on Different Agglomeration Structure

Knowledge spillover has effects on the regional innovation performance which has attracted attention extensively.In this paper we take the effects into knowledge production function (KPF) to investigate the impacts of knowledge spillover generated by spatial agglomeration of production activities on innovative output.In other words,MAR spillover,Jacobs spillover and Porter externalities,which one is more important? The econometric analysis of 1993-1995 and 2005-2007 shows that the specialization spillover presents consistent and positive effect in the two periods,and diversity spillover takes negative effect in the initial period but positive effect in 2005-2007,compared with the monopolistic market structure,competition has a more pronounced impact on the regional innovation performance.
