调查表明京沪穗网民主导“B2C”
根据蓝田市场研究公司对全国16个城市网民的调查表明，北京、上海、广州网民最近3个月有网上购物行为的人数比例分别为13.1%、5.3%、6.1%，远远高于全国平均水平的2.8%；北京、上海、广州三地最近3个月中有网上购物行为的人数比例平均为8.6%。尽管互联网的冬季仍未过去，但调查结果预示，京、沪、穗三地将成为我国互联网及电子商务的早春之地，同时是B2C电子商务市场的中心地区，并起着引领作用，足以引起电子商务界的关注。
调查还发现，网民中网上购物的行为与城市在全国的中心化程度有关，而与单纯的经济发展水平的关联较弱。深圳是全国人均收入最高的城市，大连也是人均收入较高的城市，但两城市网民的网上购物人数比例分别只有1.1%和1.9%，低于武汉、重庆等城市。
蓝田市场研究公司通过两年的调查认为，影响我国B2C电子商务发展的因素，除了经常提到的网络条件、网民数量、配送系统、支付系统等基础因素外，还要重视消费者的购物习惯、购物观念，后者的转变甚至比前者需要更长的时间和耐心。
