交通基础设施对高技术产业空间区际集聚发展的实证研究

Empirical Research on the Influence of TransportationInfrastructure on the Spatial and Inter-regional Agglomeration of High-tech Industry

运用面板数据实证研究了中国公路与铁路的发展对高技术产业的集聚效果;利用莫兰指数测量高技术产业的空间溢出效应;利用空间计量模型探究交通基础设施对高技术产业的空间溢出效应。同时考察了交通基础设施对高技术产业内部子行业的异质性影响效果。研究结果表明:交通基础设施对高技术产业存在显著的影响,其中公路与铁路在不同时期对高技术产业集聚存在逆向影响。在医药制造业方面,铁路对医药产业集聚出现倒N型的非线性影响关系;在电子与计算机制造业方面,公路对电子与计算机制造业产生了N型影响关系;在航空航天制造业方面,其受公路的影响表现出倒N型趋势,受铁路的影响表现出N型非线性关系。

Using panel data,this paper empirically studied the agglomeration effect of highway and railway development on the agglomeration of high-tech industry in China.Meanwhile,Moran's Index was used to measure the spatial spillover effect of the high-tech industry.The spatial spillover effect of transportation infrastructure on the high-tech industry was investigated by the Spatial Durbin Model(SDM).At the same time,the effects of transportation infrastructure on the heterogeneity of internal sub-industries of the high-tech industry were also investigated.The basic conclusion is that transportation infrastructure has a significant impact on the high-tech industry,and highways and railways have a reverse impact on high-tech industry agglomeration in different periods.The railway has an inverted N-shaped non-linear influence on pharmaceutical industry agglomeration.The highway has an N-shaped influence on electronics and the computer manufacturing industry.For the aerospace manufacturing industry,it shows an inverted N-shaped trend affected by highways,and an N-shaped nonlinear relationship affected by railways.
