我国相邻区域人力资本与区域创新能力的非线性关系研究
发布时间：2018-07-18 12:22
【摘要】：文章采用中国31个省市1995-2013年的年度面板数据将交通基础设施作为门限变量,使用面板门限模型研究交通基础设施与人力资本的跨区域溢出、人力资本的跨区域溢出对我国相邻区域创新能力的影响,并探讨了交通基础设施对区域创新能力是否具有门限效应。研究结果表明:人力资本具有空间溢出效应,不仅对本区域的技术进步产生影响,而且通过交通基础设施,对相邻区域的创新能力也具有显著影响。同时,人力资本对中国区域创新能力具有交通基础设施单门限效应,公路基础设施和铁路基础设施门限值分别为4.496和2.766。意味着当公路密度和铁路密度的对数值小于门限值时,交通基础设施不完善,区域之间人力资本流动的空间成本较大,区域间隐形知识的流动较少,从而对相邻区域创新能力的提升也有限。当交通基础设施大于门槛值时,交通基础设施较为完善,对相邻区域之间人力资本的频繁流动起到了重要作用。
[Abstract]:This paper uses the annual panel data of 31 provinces and cities in China from 1995 to 2013 to take the traffic infrastructure as the threshold variable and uses the panel threshold model to study the cross-regional spillover between transport infrastructure and human capital. The influence of cross-regional spillover of human capital on the innovation ability of adjacent regions in China is discussed. Whether the transportation infrastructure has threshold effect on regional innovation ability is discussed. The results show that human capital has a spatial spillover effect, which not only has an impact on the technological progress of the region, but also has a significant impact on the innovation ability of adjacent regions through the transportation infrastructure. At the same time, human capital has a single threshold effect on regional innovation in China. The threshold of highway infrastructure and railway infrastructure is 4.496 and 2.766respectively. It means that when the logarithm of highway density and railway density is less than the threshold, the transportation infrastructure is not perfect, the spatial cost of human capital flows between regions is higher, and the flow of hidden knowledge between regions is less. Therefore, the promotion of the innovation ability of adjacent regions is also limited. When the traffic infrastructure is larger than the threshold, the traffic infrastructure is relatively perfect, which plays an important role in the frequent flow of human capital between adjacent regions.
