摘　　要：[目的/意义]精准探究长三角城市群信息消费的发展态势和空间非均衡格局,为长三角城市群信息消费一体化协同发展提供了政策依据。[方法/过程]采用二次加权的纵横向拉开档次法,对2013—2017年长三角城市群信息消费发展进行了定量研究,并在此基础上,综合运用基尼系数、泰尔指数和对数离差均值全面考察了长三角城市群信息消费发展的空间非均衡格局。[结果/结论]长三角城市群信息消费发展总体呈现波动上升的特征,各城市间信息消费发展截面差异显著;长三角城市群整体的信息消费差异和各区域的信息消费差异在不断缩小,但信息消费的空间非均衡格局依然存在,其中区域间差异发展整体呈扩大态势,其贡献率远大于区域内差异和超变密度,因此缩小长三角城市群区域间差异是促进长三角城市群信息消费一体化发展的关键切入点。[Purpose/significance]Accurate understanding of the development trend and spatial disequilibrium pattern of information consumption in Yangtze River Delta urban agglomerations provides a reference for the integrated collaborative development path of information consumption in Yangtze River Delta urban agglomerations.[Method/process]Quantitative research on the development of information consumption in the Yangtze River Delta urban agglomeration from 2013 to 2017 was carried out by adopting the method of double-weighted vertical and horizontal development grade.On this basis,the spatial unbalanced pattern of information consumption development in the Yangtze River Delta urban agglomeration was comprehensively explored by comprehensive use of Gini coefficient,Theil index and logarithmic deviation mean.[Result/conclusion]The development of information consumption in the Yangtze River Delta urban agglomeration is characterized by the overall fluctuation and the development of information consumption varies significantly among cities.Yangtze River Delta urban agglomerations overall difference of information consumption and information consumption of regional differences in the shrinking,but the space unbalanced pattern of information consumption still exist,including regional development difference between expanding trend on the whole,its contribution rate is greater than regional difference and variable density,therefore to reduce the differences between the Yangtze River Delta urban agglomeration area is the key to promote the development of Yangtze river delta urban agglomeration integration of information consumption.
