Spatiotemporal Characteristics of Eco-transport Efficiency in Transport Hub Cities of China
This study aims to explore the development stages and spatiotemporal characteristics of eco-transport efficiency within Chinese transport hub cities and to identify effective pathways for fostering green and low-carbon comprehensive transportation systems.A selection of 20 international integrated transport hub cities in China serves as the research subjects.The paper employs the super-efficiency EBM(Epsilon-Based Measure)model to calculate eco-transport efficiency and applies the kernel density estimation method,standard deviation ellipse method,and Dagum Gini coefficient to explore their characteristics of spatiotemporal evolution and regional difference.The findings reveal that,between 2011 and 2021,the overall eco-transport efficiency within the 20 hub cities showcased significant development but failed to reach an effective level.Comparison among hub cities based on their transport functions indicated a hierarchy of efficiency:seaport hub cities>railway hub cities>aviation hub cities.With the accelerated construction of various transport infrastructures in China's early stages and the gradual implementation of the green and low-carbon transport development strategy in the later stage,there is a fluctuation in overall eco-transport efficiency,initially decreasing and then increasing.Meanwhile,the polarization phenomenon among cities exhibited instability,but the number of cities with high-efficiency values was increasing.The spatial distribution presented a"Southwest-Northeast"pattern,agglomerating from the southwest toward the northeast.Coastal hub cities exhibited higher average efficiency compared to their inland hub cities,and the overall regional difference and inter-regional difference showed the same trend of first expanding and then narrowing.
