摘要
新经济增长理论强调知识溢出对经济增长的贡献,知识溢出对区域经济的共同增长具有重要意义。知识溢出不仅具有规模经济,而且还具有范围经济和联结经济。知识溢出的规模经济根源于知识的MAR和Porter外部性,知识溢出的范围经济根源于知识的Jacobs外部性,联结经济则来源于知识的租金外部性。知识溢出的经济效应的发挥受到空间距离、市场结构、接受能力和社会网络等因素的影响。

Knowledge spillovers not only has economies of scale, but also has economies of scope. Economies of scope for knowledge spillovers roots in knowledge MAR externality and Porter externality, economies of scope for knowledge spillovers roots in knowledge Jaeobs externality, economies of connection for knowledge spillovers roots in knowledge preeuniary externality. Economic effects of knowledge spillovers bring into play due to spatial distance, market structure, accepting ability, social networks.
