联动发展与亚洲城市可持续竞争力水平整体提升——基于空间外部性视角

Linkage Development and the Overall Improvement of Asian Cities’ Sustainable Competitiveness Level:Based on the Perspective of Spatial Externalities

针对全球经济危机的缓慢复苏和亚洲经济的快速崛起,激烈的城市竞争不仅表现为经济竞争力的竞争,还表现为城市可持续竞争力的竞争。采用空间计量经济学的GNS方法,对亚洲655个样本城市的可持续竞争力进行研究发现,邻居城市可持续竞争力水平提升对目标城市的促进作用最大值为0.694,城市获得的空间外溢效应对城市可持续竞争力的弹性值最大为0.067,其有效距离阈值均在800 km范围之内,重要影响不可忽视;同时,基础设施、社会包容和制度管理水平的提升对亚洲可持续竞争力提升的促进作用极强,而经济活力、环境质量和人力资本潜力的促进作用较强,最后则为科技创新和全球联系。

With the slow recovery of the global economic crisis and the rapid rise of the Asian economy,the fierce urban competitiveness will not only be manifested as competition for economic competitiveness,but also as a competition for sustainable competitiveness of cities.This paper uses the GNS method of spatial econometrics to study the sustainable competitiveness of 655 sample cities in Asia,and makes up for the shortcomings of existing researches in quantitative analysis.The study found that the maximum contribution to the target city′s sustainable competitiveness is 0.694,its spatial spillover effect of has a maximum elastic value of 0.067 for urban sustainable competitiveness,and the effective distance threshold is 800 km within which,its important influence cannot be ignored.At the same time,the improvement of infrastructure,social inclusion and institutional management have a strong effect on the promotion of sustainable competitiveness in Asia,followed by economic vitality,environmental quality and human capital potential,and finally by technological innovation and global linkages.The conclusions of this paper have some important policy implications for optimizing the level of sustainable competitiveness of cities and improving the region′s overall sustainable competitiveness level.
