〔一〕研究的选题与立意
21世纪世界经济开展的一个突出特征是以信息产业为重点的高新技术产业成为推动经济开展的主导力量。现代信息技术的开展，特别是电子商务的开展，使世界各国的生产方式、贸易方式及竞争方式都发生了重大变化，对外贸企业经营方式、管理方式和国际竞争力构成挑战。
随着世界经济全球化进程的加快，以Internet为载体的电子商务正以迅猛的速度在全球范围内应用和普及，这是一种新兴的、处于开展过程中的现代商务方式，自20世纪90年代出现就已显现出巨大的经济贸易潜力，被认为是未来国际贸易的开展主流。1996年全球网上贸易交易额只有23亿美元，1998年增加到500亿美元，1999年为1450亿美元，2000年是3000亿美元。[1]
