Spatiotemporal Differentiation of Transportation Supply Level and Its Influencing Mechanism in Northeast China under the Background of Population Shrinkage
On the basis of identifying the population growing and shrinking areas in Northeast China,and evaluating the transportation supply level in multiple dimensions,this paper conducts a comprehensive analysis framework of the influencing mechanism of transportation supply level change.Based on this framework,it discusses the regional differentiation and spatiotemporal evolution characteristics of transportation supply level in Northeast China under the background of population shrinkage,and explores the influencing mechanism of population growth and shrinkage on the change of transportation supply level.The results indicate that:1)From 2013 to 2020,the transportation supply level in population shrinking areas of Northeast China was always significantly higher than that in population growing areas.The transportation supply shortage was prominent and intensified in population growing areas,the transportation supply tended to be moderate in slight shrinking areas,and that in severe shrinking areas was seriously mismatched and tended to be oversupplied.2)The increase of the average annual population change rate promotes the improvement of the transportation supply level in population shrinking areas,but has no significant effect on population growing areas.Good natural conditions and high public service level promote the improvement of the transportation supply level in Northeast China,while financial capacity is manifested as a restraining effect.There are regional differences in the impact of industrial development on the improvement of the transportation supply level.The increase of regional area inhibits the increase of the transportation supply level in population shrinking areas,while the influence of regional conditions also has regional difference.3)The increase in regional population and factor flow demand caused by rapid industrial development is the main reason for the shortage and degree aggravation of the transportation supply in population growing areas.The change of the transportation supply level is mainly due to the reduction of transportation demand caused by population loss and sluggish industrial development in population shrinking areas.
