我国手机回收结构特征及其科技政策内涵分析——基于技术产品生命周期的视角

废旧手机回收构成电子废弃物回收政策研究的新课题。在我国,手机生命周期的相关企业中,手机维修商和二手手机商回收贡献突出,而手机厂商和手机拆解商贡献不足,形成了"橄榄型"结构特征。这种"橄榄型"结构凸显支撑我国废旧手机回收的科技政策乃至电子废弃物回收科技政策,应该区别于发达国家,应该节约资源与治理环境并重,应该重点促进旧手机等旧物回收再利用技术的创新和扩散。

Two Principles of Broadcast Media Ownership for a Democratic Society

Technological advances in media communications have raised questions about the appropriateness of media ownership rules for traditional TV and radio broadcast. This article contributes to this debate by defending a set of principles that ought to govern the distribution of broadcast spectrum. In particular, it defends principles reflecting the ‹public interest’ constraint currently informing broadcast media ownership rules, and argues against a free-market procedure for distributing spectrum use. The argument relies upon the application of a political constructivist approach typical to many political theories. In applying this approach, the author illustrates the strengths and weakness of constructivism and in the process provide an example for how constructivism can be applied to other subjects. As a result, the article has two aims. First, it defends a set of broadcast ownership principles. Second, it provides a model for how philosophers might apply constructivism to other subjects.     

我国电子商务环境下的移动支付问题研究

移动支付是在交易活动中以手机作为支付手段,即将手机与信用卡号码链接起来通过手机代替信用卡来支付交易费用,它具有方便、安全、成本低廉等优势,但目前的消费观念、技术支持、利益分配、手续繁杂等多种因素制约了移动支付的快速发展。我国移动支付在现有技术条件下主要有虚拟支付和移动现场支付两种基本模式。移动支付提供商应着力于创新商业模式,实现产业共赢;正确定位,积极开发市场;强化技术支撑,确保交易安全;加强行业协同,规避政策风险;利用新技术,抢占新市场。     

Roaming in the Mobile Internet

With the acquisition of UMTS licenses Mobile Operators (MOs), have often been obliged to deploy 3G network infrastructures covering at least a given percentage of users by a given date. This paper discusses the rationale for imposing these minimum coverage requirements by regulatory bodies. To that end, a model is built, which studies the incentives for MOs to compete for market share and over coverage within an unregulated environment where MOs are assumed to be free to enter sharing agreements and to negotiate a reciprocal roaming charge. Within this framework, it is first shown that MOs would deploy their infrastructure to guarantee the coverage of the entire territory (population), but they would avoid any network duplication in order to maximize rents from roaming revenues. It is then discussed whether a minimum coverage requirement is the best policy to reduce these excess rents, or whether alternative measures could be adopted which could serve other goals as well, such as the avoidance of network duplication.     

Managing and modeling the price reduction effect in mobile telecommunications traffic

As needs for telecommunications services diversify, an increasingly wide range of services is becoming available in the market. Service price reduction is one strategy used by service providers to retain existing subscribers. A price reduction for one service, however, can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, an individual-level usage model for telecommunications services is developed and the effects on usage of a price reduction are analyzed. The model is applied to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, a 0-1 integer programming model is proposed for choosing which market segment should be targeted with a price reduction to minimize revenue loss. These models can be applied to market segmentation and price reduction strategy.     

Market structure in mobile telecoms: qualified indirect access and the receiver pays principle

Scarcity of spectrum limits the number of competing network operators in mobile telecoms. In the United Kingdom a regulatory review is currently enquiring into the effects of limited competition in the mobile market. The European Commission is also reviewing competition in roaming across mobile networks in Europe. In the UK the industry regulator Oftel claims that the prices for calling mobile phones are too high. We show that such relatively high prices stem from asymmetric incentives. The convention in the UK is for the originating party to pay for a telephone call. If instead the receiver were to pay for some or all of a call, we show that prices of calls to mobiles would be lower. We also argue that qualified indirect access could stimulate more effective competition in mobile telecoms.     

The moderating influence of brand image on consumers' adoption of QR-code e-wallets

In a post-pandemic era marked by thriving digital payments and e-commerce transactions due to physical distancing norms, the growth of mobile payments or E-wallets is expected to expand in tandem with the global trend toward cashless payment solutions. However, it is unclear whether this momentum would be sustained for over-the-counter (OTC) retail payments, particularly QR-code E-wallets, that are more affordable and accessible to merchants and customers than NFC-based (near field communication) systems in emerging markets. This study aims to model the interaction effects of brand image in shaping consumers’ E-wallet usage intentions. Incorporating a consumer-brand relationship element (i.e., brand image) should improve the understanding of consumers’ digital service experiences in proximity-based retail encounters. The research model was empirically tested using 305 responses from QR-based E-wallet users in the Klang Valley, Malaysia. Statistical analysis was performed using structural equation modeling (SEM) to test the hypotheses. An empirical examination of the model revealed effort expectancy, social influence, hedonic motivation, and perceived value as significant positive predictors of consumer usage intention. Furthermore, brand image was found to significantly strengthen the positive effect of perceived value and weaken the positive impact of hedonic motivation on the outcome. The study’s key contributions include reaffirming the crucial contingent role of brand image in consumer technology adoption studies and investigating consumer perceptions of QR-based E-wallets, which are expected to gain traction, especially in emerging markets. E-wallet providers should reinforce their value propositions by providing seamless, engaging, and easy-to-use experiences that improve users' brand perceptions.

Mobile money,agricultural marketing,and off‐farm income in Uganda

Mobile money (MM) services can contribute to welfare gains in smallholder farm households. Previous research showed that one important pathway for these MM‐related welfare gains is through higher remittances received from relatives and friends. Here, the role of other impact pathways is examined, especially focusing on agricultural marketing and off‐farm economic activities. The analysis builds on panel data from smallholder coffee farmers in Uganda. Regression models show that the adoption of MM technology has contributed to higher household incomes and consumption levels. Off‐farm income gains are identified to be an important pathway, also beyond remittances. Typical off‐farm income sources are small businesses in trade, transport, and handicrafts, which benefit from novel savings and money transfer opportunities through MM. In terms of agricultural marketing, MM users sell a larger proportion of their coffee as shelled beans to buyers in high‐value markets, instead of selling to local traders immediately after harvest. MM services help to reduce cash constraints and facilitate transactions with buyers from outside local regions. In conclusion, MM can contribute to rural development through various important pathways. Analysis of adoption patterns suggests that MM services are socially inclusive.
