This paper introduces the overall demands of AHP evaluation system firstly, and then presents some key technologies to implement AHP evaluation system, including mainly AHP evaluation index architecture based on XML, the class of AHP model, the Web service encapsulation of AHP, the publication and invocation of AHP and the client application. At last, the system is used to analyze the impact factors of online consumption behavior.展开更多

Compared with developed countries, however, China's service sector, especially modern services, remains rather undeveloped in terms of its aggregate size and internal industrial structure. The underlying reason is that the international OEM model under an export-oriented strategy created both technology spillovers and crowdingout effects on domestic service firms. With the deepening global division of work, such a market crowding-out effect is outweighing the technology spillover effect. This paper suggests that China's service sector must shift towards a domestic consumption-based strategy, utilize domestic and foreign production factors, and promote service sector innovation and development in differentiated monopolistic competition.展开更多
