摘要
基于西部地区11省及自治区2005—2019年的统计数据,构建空间计量模型和门槛模型,分析科技创新、交通基础设施与产业结构升级的空间效应和门槛效应。结果显示:在经济距离空间矩阵下,科技创新和交通基础设施都能够显著促进本地区产业结构升级,但科技创新的空间溢出效应不显著,交通基础设施的空间溢出效应显著;在地理邻接权重矩阵下,科技创新对产业结构升级具有正向的空间溢出效应,交通基础设施的空间溢出效应不显著;科技创新促进产业结构升级时,受到交通基础设施建设门槛效应的约束,西部地区交通基础设施建设已经突破需要的门槛。因此,应当着力支持科技创新,促进西部地区产业链的加速形成;利用交通便利条件,促进西部地区产业结构优化升级;尊重规律协同推进,促进西部地区科技成果转化利用。
Based on the statistical data of 11 provinces and autonomous regions in the western region from 2005 to 2019,this paper constructs a spatial econometric model and a threshold model to analyze the spatial and threshold effects of scientific and technological innovation,transportation infrastructure and industrial structure upgrading.The results show that under the spatial matrix of economic distance,both scientific and technological innovation and transportation infrastructure can significantly promote the upgrading of the industrial structure in the region,but the spatial spillover effect of scientific and technological innovation is not significant,and the spatial spillover effect of transportation infrastructure is significant.Under the geographic adjacency weight matrix,scientific and technological innovation has a positive spatial spillover effect on the upgrading of industrial structure,and the spatial spillover effect of transportation infrastructure is not significant.When scientific and technological innovation promotes the upgrading of industrial structure,constrained by the threshold effect of transportation infrastructure construction,the transportation infrastructure construction in the western region has broken through the required threshold.Therefore,we should focus on supporting scientific and technological innovation to accelerate the formation of the industrial chain in the western region,take advantage of the convenient transportation conditions to promote the optimization and upgrading of industrial structure in the western region,and respect the laws and coordinate to promote the transformation and utilization of scientific and technological achievements in the western region.
