American e-commerce models may not work in some Asian markets, according to Jack Ma, founder of mainland-based international trading community Web-site operator Alibaba.com. 'For example, the eBay and Amazon.com [business-to-consumer] models may not work in China, [where] credit-card usage is low,' he said at an AsiaatHong Kong Internet conference yesterday. In the business-to-business arena, he said in North America and Europe, the focus tended to be between large suppliers and buyers through electronic data interchange, while in Asia, most of the activities were among small and medium-sized companies. He also noted the poorly organised and fast-changing nature of the Asian Internet market, in which most small businesses are unwilling to pay for on-line services. He said flexibility and fast response to market changes were key to success in the Asia Internet market. Alibaba has obtained US$5 million of venture capital fund since it was set up seven months ago, despite having no income stream to support its operation.
