基于《国际城市发展报告》提出的国际城市2.0评价指标体系，本文从综合能力升级等7个维度对所观察的40个城市进行分析。结果表明，综合升级能力、社会升级能力、生态升级能力、治理升级能力和空间升级能力整体呈现趋同的趋势，且为左偏分布，升级能力得分较高的城市相对较多；而涉及创新的经济升级能力和文化升级能力高分城市依然较少，文化升级能力低分城市集聚，表明当前国际城市经济和文化间的升级能力差距逐步扩大，强者越强，弱者赶超压力增大。综合能力趋同、创新能力极化的总体趋势，表明城市政府亟须重视经济与文化在创新方面的提升。
Based on the index system of international city 2.0 evaluation proposed by the International City Development Report，this paper analyzes the 40 cities observed from 7 dimensions，such as comprehensive capacity upgrading，et al. The results show that the comprehensive upgrading capacity，social upgrading capacity，ecological upgrading capacity，governance upgrading capacity and spatial upgrading capacity are in the same trend，and the cities upgrading capacity have higher scores with the left-side distribution. Economic upgrading capacity and cultural upgrading capacity of high score city are still less. The cities with lower cultural upgrading capacity are the most，indicating that currently the gap of international economic and cultural upgrading gradually expand，the stronger cities still are the stronger，the weaker cities have catching up pressure. The general trend of the convergence of comprehensive capacity and the polarization of innovation capacity indicates that the city government needs to pay much more attention to the promotion of economy and culture in innovation.
