Beijing-based technology consulting firm China Enterprise ASP has launched the mainland's first one-stop business-to-business e-commerce platform for small to medium-size companies. California-based Sun Microsystems helped build the platform, in which China Enterprise said it had invested 50 million yuan (about HK$46.82 million). China Enterprise vice-chairman Zhang Hongren said there was high demand in the mainland to adopt e-commerce 'as a way to expand business and to cut costs'. 'But most mainland companies are usually unfamiliar with sophisticated e-commerce solutions,' he said. China Enterprise's strategy will be to target small and medium-size mainland enterprises with its platform, allowing buyers and sellers to search for trading partners online. China Enterprises said it already had about 8,700 paying members and expected to sign 900 new members a month. 'We take in an average income of 5,000 yuan per member per month and aim to increase that to 25,000 yuan within two years,' Mr Zhang said. China Enterprises, which was formed in 1994, has its headquarters in Beijing with 14 sales offices in various major mainland cities. The company is 80 per cent-owned by Hong Kong-listed property and information technology firm Sino-i.com, which is run by former Ming Pao Enterprises chairman Yu Pun-hoi. The company also has a 60 per cent-owned joint-venture with the mainland's All China Federation of Industry and Commerce, and hopes to tap its 1.35 million corporate members.
