摘要
高速公路是综合交通运输体系的重要组成部分,是区域资源要素便捷流动的基础支撑。基于福建省公路与经济数据,分析2010—2020年福建高速公路密度和县域经济发展水平的时空演化特征,采用空间面板模型和时空地理加权回归揭示高速公路对县域经济发展的空间效应及其异质性。研究发现:①2010—2020年福建各县域高速公路密度均大幅增加,集聚化趋势明显。高密度县域集中于东部沿海地区,中、西部和北部县域的高速公路密度较低。②2010—2020年福建县域经济发展水平显著提高、空间差异趋于缩小,中、西部低水平县域集聚范围缩小,东部沿海高水平县域集聚范围扩大。县域经济发展水平与高速公路密度空间分布一致性较高。③福建高速公路对县域经济发展具有显著的正向促进作用,并且空间溢出效应更加突出。但相比普通公路,高速公路对县域经济发展的直接和间接促进作用都较弱。④福建高速公路对县域经济发展的作用效果具有空间异质性,对西部和南部县域的经济促进作用较弱,对东部和北部县域的经济促进作用更强。
Expressway is an important part of the comprehensive transportation system and the basic support for the convenient flow of regional resource elements.Based on the expressway and economic data of Fujian province,this study analyzes the spatial and temporal evolution characteristics of expressway density and economic development level of counties in Fujian from 2010 to 2020 and reveals the spatial effect and spatial heterogeneity of expressways on economic development of counties by using spatial panel model and spatial and temporal geographically weighted regression.The findings of the research are as follows:(1)The density of expressways in all counties in Fujian increased significantly from 2010 to 2020,and the trend of spatial agglomeration is obvious.Counties with high expressway density are concentrated in the eastern coastal areas of the province,and those with low expressway density are mainly distributed in the central,western,and northern parts.(2)The level of economic development in Fujian's counties from 2010 to 2020 increased significantly.At the same time,the spatial differences in the level of economic development in counties tended to narrow.The spatial agglomeration range of counties with low-level economic development in the central and western parts of the province narrowed,while the spatial agglomeration range of counties with high-level economic development in the eastern coastal areas expanded.The level of economic development of counties is highly consistent with the spatial distribution of expressway density.(3)Expressway plays a significant positive role in promoting the economic development of counties in Fujian.Moreover,the spatial spillover effect of expressways on the level of economic development of counties in the province is more prominent than the direct effect.However,compared with ordinary highways,the direct and indirect promotion effects of Fujian's expressway on the development of the county economy are weaker.(4)The promotional effect of Fujian's expressway on county economic
