| 摘 要： | 为了从外部性角度说明目前陕西省交通基础设施的建设和投资在地域上存在的问题,为陕西省交通基础设施建设方向提供理论帮助,基于陕西省2009~2017年间各市相关数据,在交通基础设施对经济增长效应研究的直接效应和溢出效应基础上,加入空间要素,构建生产函数和空间权重矩阵,通过自相关检验（莫兰指数）、LM检验和 Hausman检验,选取合适的空间面板计量模型对陕西省交通基础设施的经济溢出情况进行研究。研究认为,2009~2017年间陕西省交通基础设施对经济增长的溢出效应（显著）整体为负,但依然存在正溢出的局部地区,即以西安为首的经济聚集区（西安、宝鸡、咸阳）和榆林、延安联合的陕北经济聚集区,资源过于集中和两个高地之间缺乏互联互通是整体呈现负溢出的重要原因。在地域分配的量和质上应充分考虑交通基础设施的溢出效应,避免资源过度集中在西安,在两个经济高地之间打通一条经济要道,并重点扶持相对落后又有发展前景的城市可促使陕西经济发展由总体集聚向总体扩散转变。

| Abstract: | In order to shed light on the regional problems in the construction and investment of the transportation infrastructure in Shaanxi province from the perspective of externality, and to offer theoretical help for the construction direction of the transportation infrastructure, this paper adds the spatial elements to the study on the direct effect and spillover effect of the transportation infrastructure on economic growth based on the relevant data of various cities in Shaanxi province from 2009 to 2017, constructs the production function and spatial weight matrix, and selects the appropriate spatial panel econometric modelto study the economic spillovers of the transportation infrastructure in Shaanxi province through the autocorrelation test (Moran index), LM test and Hausman test. The results show that the spillover effect of transportation infrastructure on economic growth in Shaanxi province from 2009 to 2017 is negative on the whole (significant), but positive spillover still exists in some areas, namely, the economic clusters (Xi’an, Baoji, Xianyang)with Xi’an as the most typical caseas well asthe northern Shaanxi economic clusters combiningYulin and Yan’an. Overconcentration of resources and lack of interconnectivity between the two uplands are important reasons for the overall negative spillover. In terms of the quantity and quality of geographical distribution, the spillover effect of transportation infrastructure should be fully considered to avoid the overconcentration of resources in Xi’an. It is suggested that the government should constructa major economic pathwayconnectingthe two economic uplands, and give priority to supporting the relatively backward cities with promising development prospects to promote the transformation of Shaanxi’s economic development from overall agglomeration to overall diffusion. |
