1.1课题背景
中国的B2B电子商务是靠“资讯”起家的。企业商机在B2B电子商务平台查询和发布，已经被很多企业所熟悉和了解。至今，虚拟店铺、供求信息、行业评论卖的钱依然足以支撑一个网站的运营。但是随着电子商务的发展和纵深，简单的信息服务已经不能满足商家的需求，专业化，行业化很大程度决定了资讯的含金量。
传统B2B电子商务平台服务商“扎堆”在信息流部分，主要是受困于网络交易中信用和支付的瓶颈。在商务部研究院院长柴海涛于商务信用体系的报告中提到:因信用问题引发的企业直接和间接损失每年高达5855亿，相当全国财政收入的36.8%;而合同交易只占整个交易量的30%，履约率仅60%左右。商务信用问题已经成为制约社会经济发展的瓶颈。由此看开电子商务交易在中国正在不断的发展，并得到了国家的有利支持，我相信它的前景是光明的。
