3G telecommunication operators’ challenges and roles: A perspective of mobile commerce value chain

In recent years, in the wake of the bottleneck facing the e-commerce development, mobile commerce is another type of service many expect to utilize and develop. In the past, influenced by the bandwidth limitation, the promotion of mobile commerce was not successful. Now, the 3G technology has broken through the limitation, allowing a higher transmission rate and more complex e-commerce interactions. The mobile commerce value chain is then formed. On this value chain, 3G telecommunication operators are the most crucial members. Moreover, mobile commerce value chain is essentially the aggregation of the conventional mobile communication value chain and Internet value chain. The business models and value chains of the conventional mobile communication and the Internet may not completely apply. Thus, a further investigation into the roles that 3G telecommunication operators play on the mobile commerce value chain is indeed necessary. As a result, based on the value chain, this study attempts to investigate the present and future challenges for 3G telecommunication operators and their advantages, to outline the roles they may play in the future development of mobile commerce.     

Revised planning matrix of quality function deployment

Quality function deployment (QFD) has been adopted to improve product quality and development in many fields. Numerous studies have demonstrated that attribute importance and attribute performance have a causal relationship and the customer self-stated raw importance is not the actual importance of a customer attribute. These findings generate questions regarding the applicability of the conventional planning matrix (PM) of QFD. This study presents a revised PM that integrates a back-propagation neural network and three-factor theory to assist practitioners in determining the actual importance of customer attributes. An illustrative case demonstrates the effectiveness of the revised PM and identifies the shortcomings generated when applying the conventional PM.     

中国进口汽车零部件构成整车特征的认定与征税案的分析与建议

文章认为,进口汽车零部件构成整车特征认定是进口物品归类方法,没有改变关税的框架、税率,没有提高关税税赋。对进口货物的关税归类方面,我国具有广泛的自由决定权。构成整车特征的零部件被归类为与整车属同类产品的情况下,被征收的增值税不高于对国内同类整车征的税。进口汽车零部件构成整车特征认定措施的目的是为防止关税规避,避免关税流失,而非对国内生产提供保护。
