文章地理集群为切入点,综合新经济增长理论和新经济地理理论,论述了以交通基础设施与电信基础设施为代表的网络基础设施影响区域创新能力的内在路径。结论表明,网络基础设施表现出的网络特性具有明显的外部性,这种外部性使得网络基础设施对区域创新能力具有两面性影响:一方面导致网络基础设施与知识跨区域溢出具有显著相关性,使得网络基础设施对相邻区域的创新能力产生影响,即网络基础设施对区域创新能力具有空间溢出效应;另一方面导致网络基础设施对区域知识吸收能力产生重要影响,即网络基础设施对区域创新能力具有门限效应。
Article Geographical Clusters as a starting point, the new economic growth theory and new economic geography theory, discusses the transport infrastructure and telecommunications infrastructure as the representative of the network infrastructure to influence the regional innovation ability of the internal path. The conclusion shows that the network characteristics exhibited by the network infrastructure have obvious externalities, which make the network infrastructure have a dual impact on the regional innovation capability. On the one hand, it leads to the significant correlation between the network infrastructure and the cross-regional knowledge overflow, Network infrastructure has an impact on the innovation ability of the adjacent areas, that is, the network infrastructure has a spillover effect on the regional innovation capability; on the other hand, the network infrastructure has an important impact on the capacity of regional knowledge absorption, that is, Threshold effect.
