摘　　要：通过长三角各城市综合实力计算所得的扩展率分析,得到长三角影响腹地的基本特征和规律,认为泰州、常州、宁波有可能形成新的区域中心。同时,通过对区域通达性的分析,指出区域通达性的短期改变会放大区域扩展率差异;而长期的、逐步的改善因伴随区域整体发展水平的提高,反而会缩小区域扩展率差异。By analyzing the city comprehensive competence,it finds the features and rules of the hinterland in the Yangtze River Delta and argues that Taizhou,Changzhou and Ningbo are prone to become new regional centers.By analyzing the regional accessibility,it extends that the short-term alteration in regional accessibility will enlarge the expansibility differences while the long-term and gradual improvement,which is companied with the enhancement of the regional comprehensive development level,will reduce the regional expansibility differences.
