中国高新技术产业集群知识外部性效应分析

近年来,中国科技体制改革取得重大成就,国家高新技术产业快速发展。知识外部性作为产业集群发展的驱动因素,其在创新生态系统中的溢出效应日益受到学者的重视。以91个城市国家级高新技术产业开发区为研究对象,对其知识外部性的Mar效应和Jac效应进行测度,并给出国家高新技术产业集群知识外部性的辐射范围,定量计算知识外部性对经济增长和技术进步的效应。结果表明:中国高新技术产业集聚过程中产业内知识溢出效应更大,西部地区高新技术产业集群Jac外部性对于区域经济增长更具有显著的正向作用。研究的创新点在于,同时兼论了Mar效应和Jac效应,将样本划分为东部、中部、西部和东北部进行测度和分析,研究结论更具有区域针对性。

The Studies of Knowledge Externalities Effects in High-Tech Industry Clusters in China

This paper takes 91 cities'' national high-tech industrial development zones as the research object, measures the Mar effect and Jac effect of their knowledge externalities, and gives the radiation range of knowledge externalities of national high-tech industrial clusters, and quantitatively calculates the knowledge externalities effect on economic growth and technical advancement. The results show that the knowledge spillover effect of the industry in the process of agglomeration of high-tech industries in China is greater, and the Jac externalities of the high-tech industrial clusters in the western region have a more significant positive effect on regional economic growth.
