| In the new stage of high-quality economic development,promoting the upgrading of industrial structure has become an important way of high-quality economic development.At present,China's industrial structure is in a period of transformation from the secondary industry to the tertiary industry.Deep-seated problems such as unbalanced regional development and industrial overcapacity still exist,which affect the quality of economic development.As the material carrier of factor flow,transportation infrastructure plays an increasingly important role in promoting the upgrading of industrial structure in various regions with the continuous development in recent years.Therefore,the study on the impact of transport infrastructure on industrial structure from this perspective is in line with the realistic needs of economic development in the new era.In this paper,based on the above background.On the basis of combing the literature induces the influence mechanism of action,use the 2008-2017 provincial panel data,from the angle of the spatial correlation and spatial heterogeneity,transport infrastructure on industrial structure optimization and upgrading of the specific role in different areas.The study found that: China's transportation infrastructure construction and industrial structure optimization and upgrading level show obvious spatial agglomeration characteristics,there is an inverted "U" type of spatial spillover effect.Traffic construction in adjacent areas can affect the local industrial structure upgrading at a certain scale.At the same time,there are significant differences in the impact of transportation infrastructure on industrial structure in different regions,showing a tendency of gradual weakening from north to south,with spatial heterogeneity.This paper puts forward corresponding countermeasures and Suggestions for transportation infrastructure construction and industrial policy. |
