21世纪是城市世纪，城市竞争力研究一直是国内外学者研究的焦点和热点。以我国15个副省级城市为例，从城市经济、创新、基础设施、开放水平、环境等五个方面构建了副省级城市竞争力的评价指标体系，运用熵权TOPSIS分析法，深入研究了副省级城市综合竞争力的时空演变过程。研究发现：时间序列上，各城市排名波动不大，城市之间的差距存在变动，整体呈现缩小态势。空间分布上，竞争力水平虽呈现东南沿海城市向东北递减的梯度变化格局，但区域逐渐趋于均衡化发展。%The research of urban competitiveness has been the focus and hot spot of domestic and foreign scholars and the 21st century is the century of the city. This paper takes 15 vice provincial cities as the research object and sets up the evaluation index system of urban competitiveness in 15 vice provincial cities based on economy, innovation, infrastructure, opening level, and environment. Based on entropy TOPSIS method, this paper analyzes in depth the spatial and temporal characteristics of the 15 vice provincial cities. According to the analysis result, the basic points of view are obtained as follows: From the perspective of the time alignment, the gap between cities has changed al the time and there is a shrinking trend among cities. The spatial distribution of competitiveness level presents the change pattern which descends form southeast coastal cities to the northeast. However the development of the region gradualy tends to be balanced.
