摘　　要：文章以江苏为例,运用主成分分析法对其城市综合实力进行评价与演变分析。实证结果表明:江苏省城市综合实力在空间上由北到南呈现增长态势,其中苏州、南京等城市综合实力较强,近年来对外贸依赖程度逐步减少,发展重心向国内自身产业转移;淮安、宿迁等城市综合实力长居末位,需要加大产业结构调整和人才引进力度;连云港综合实力相对较弱,亟待加快推进对外贸易和港口基础设施建设。此外,文章还提出了加强城市间合作、促进平衡发展的建议,为江苏省城市发展提供参考。文章揭示了主成分分析法在城市综合实力评价上的应用优势,有助于深入探究城市发展的内在规律与瓶颈问题,具有一定的理论与实践意义。This paper uses Jiangsu province as a case study to employ principal component analysis(PCA)for evaluating and analyzing the evolution of the comprehensive strength of cities within the region.Empirical results indicate a spatially growing trend in urban comprehensive strength from north to south.Cities like Suzhou and Nanjing have demonstrated strong comprehensive capabilities,gradually reducing dependence on foreign trade and refocusing on domestic industrial development in recent years.On the other hand,cities such as Huaian and Suqian lag in comprehensive strength,requiring intensified efforts in industrial restructuring and talent acquisition.Lianyungang,with its relatively weaker strength,urgently needs to accelerate the advancement of foreign trade and port infrastructure.Additionally,the study offers recommendations for enhancing inter-city collaboration and promoting balanced development,providing valuable insights for the urban development of Jiangsu province.The paper underscores the applicability and advantages of principal component analysis in evaluating urban comprehensive strength,contributing both theoretically and practically to the understanding of inherent dynamics and bottlenecks in urban development.
