移动互联网使用对女性非农就业和收入的影响研究

移动互联网等数字技术的发展对实现充分就业具有重要作用，促进女性就业和创业是实现充分就业的必要前提。本文基于 2019 年中国家庭金融调查数据，研究了移动互联网的使用对女性非农就业、收入和性别工资差距的影响。研究发现，移动互联网使用促进了女性非农就业，显著缩小了与男性的就业差距。使用 Heckman 两步法和工具变量法克服内生性问题后的结果表明，移动互联网使用显著促进了女性收入的提高，且这种促进作用偏向于女性，缩小了与男性的收入差距。替换被解释变量后上述结论依然稳健。异质性分析发现，相比于从事受雇工作，移动互联网使用对女性创业的促进作用更强；但对已经就业的女性，移动互联网使用显著提升了受雇者的收入，未能显著增加创业者的收入。结论认为，为持续提高女性就业和收入，需要进一步加强移动互联网基础设施建设、转变传统的性别观念以及增强互联网对人力资本投资的作用。

Matching audio/video app features with young user preferences: An integrated approach

Audio/video mobile applications (apps) enable people to engage in leisure activities without time and space restrictions, which gradually changed human leisure behaviours. This study is one of the first to integrate means-end chain theory, Kano and conjoint analyses to reveal young user preferences for entertainment audio/video mobile apps. A preliminary qualitative survey with 36 young interviewees established the questionnaire items in the subsequent survey of 389 young respondents. Results show that ‘subtitle choice’, ‘resolution selection’, ‘top ranking list’ and ‘advertising mode and format’ are key attributes that directly influence young user willingness to download apps. In particular, ‘flashing banner ads’, ‘resolution ≤ 480 ppi’, ‘5 seconds to skip ads’, providing ‘subtitle choice’ and without ‘top ranking list’ is the best combination of attribute levels of audio/video apps that meet young users' desires. That is, young users prefer mobile apps with ‘resolution ≤ 480 ppi’ and ‘subtitle’ choices and expect that they can skip flashing banner ads in 5 s. Providing a top audio/video ranking list, however, is unnecessary for young app users. The findings can help marketers and app designers develop effective app designs and advertising strategies for young users to expedite the adoption of entertainment audio/video apps.     

How does the insurer's mobile application sales strategy perform?

While the impact of an Internet-based sales strategy on sales performance has been well studied, there is little academic research that examines the impact of a mobile application (MA) sales strategy on the sales performance of insurers. Using a unique data set for term life insurance policies from a Chinese life insurer, we study the impact of implementing this strategy on insurance purchases. We find a significant growth in the insurance purchase quantity and somewhat lower growth in premiums received from new policies. This paper determines that this is due to improved channel accessibility and the cost reduction of the MA channel. Although sales of traditional distribution channels are cannibalized in the short term by the MA distribution strategy, this substitution effect does not persist in the long run. In addition, we find that this strategy reduces impulsive purchases.     

Examining consumers' continuous usage of multichannel retailers' mobile applications

This paper examines the variables influencing a consumer's satisfaction and continuous use of a multichannel retailer's mobile application. Drawing upon the Expectation Confirmation Model for Information Technologies, post-adoption literature, and consumer behavior literature, we assess pertinent factors on the continuous usage of multichannel retailers' mobile apps. Through a sample of 1009 consumers who retained a retailer's mobile app for more than 6 months and conducting Structural Equation Modelling, the findings illustrate that utilitarian variables (perceived usefulness, ease of use, and personalization), hedonic variables (perceived enjoyment), and a brand-related variable (consumer loyalty intention toward the retailer's brand), play a significant role in influencing continuous usage of multichannel retailers' mobile apps. In contrast to e-commerce research, the study outlines that escapism plays a negative role in both consumer satisfaction and intention to continue to use a multichannel retailer's mobile app. Previous research points to the fact that consumers' retention of retailers' apps is low. This paper contributes to the emerging literature on consumers' continuous use of retailers' mobile apps through enhancing our understanding of technology and non-technology-related variables.     

An assessment of the liberalization and the evolution of competition in the Moroccan mobile market

This paper analyses the liberalization process of the Moroccan mobile market since the beginning of the 21 st century. Our database ranges from 2004 to the end of 2020. First, operators’ market shares are presented and analysed. Second, we build concentration indexes and other indicators of competitiveness. Finally, we conduct an econometric analysis to determine the extent to which regulatory measures, privatization, market structure and the population dimension determine market shares. Overall, we can argue that, although concentration remains high, the market has become more competitive since the liberalization process began. The statistical analysis and the econometric assessment show that the entrance of the third operator made the market more competitive. Indeed, there is evidence that operator companies competed to capture customers from each other during the period under study. These features suggest that mobile operators did not follow anticompetitive practices in order to restrain competition.     

多模终端待机低功耗设计

如今的移动通信网络是由多种制式及多个频段融合而成的多模网络，对于商用终端而言，多种难题交织在一起，其中待机时长是必须要解决的一个关键问题。为此，不同于传统增大电池容量的方法，采用降低待机功耗的策略：时域的时隙控制、频域的电流控制、睡眠和唤醒的电源门控制、低频时钟高频化，其中高频时钟校准低频时钟是降低睡眠态功耗的关键措施。这一系列方案的实施，使得终端在多模实际网络环境下的待机电流小于5 mA，终端的待机低功耗达到了有竞争力的商用水平。     

Narrowing the gender digital divide in Pakistan: Mobile phone ownership and female labor force participation

The unprecedented growth in access to mobile phones and smartphones has opened up new possibilities in the way people live and work. However, women in developing countries are unable to take advantage of this growth due to certain factors and socio-cultural norms that give rise to the gender digital divide. In this study, using the nationally representative Pakistan Social and Living Standards Measurement Survey (2019–2020), we investigate the gender and rural–urban (female) digital divide in a country with one of the most considerable digital divides. Furthermore, we employ an instrumental variable approach to study the effect of mobile or smartphone ownership on female labor force participation. The results indicate that institutional and sociocultural norms explain most of the ownership gap of mobile or smartphones between men and women. The instrumental variable approach demonstrates that mobile or smartphone ownership increases the participation of women in the labor force. We also find that the differences between observable characteristics, especially literacy and education, explain the rural–urban digital divide among females. Considering the importance of mobile or smartphone ownership in facilitating women's labor supply decisions, providing women with digital tools and upskilling them has wider implications for their economic well-being.     

‘Regrettable-escapism’ the negative effects of mobile app use: A retail perspective

Despite the enhanced shopping opportunities that mobile devices offer to consumers, there is a fine line between consumers enjoying the mobile shopping process and them regretting the time spent involved in it. Through the lens of Uses and Gratifications Theory (U>) and drawing on Flow Theory, this study aims to understand the effects of consumers' interactions with mobile shopping apps on their intention to reuse the app in the future, loyalty towards the brand and brand reputation. Study 1, through a questionnaire (n = 1024), provides insight into the positive and negative relationships between Utilitarian and Hedonic gratifications on intentions to reuse a retailer's mobile app, loyalty towards the b,rand and the brand's reputation. Through undertaking 24 in-depth interviews, Study 2 provides deeper insight into these relationships to uncover the complex nature of the negative effects of escapism. Findings demonstrate that the addictive nature of retailers' shopping apps lead to regrettable escapism. The flow state of mind experienced during escapism, becoming engrossed and notions of time-distortion, leave consumers with feelings of guilt and frustration due to the perceived wasted time spent on the retailer's app. Accordingly, this study advances theoretical understanding of escapism and its negative effects with ubiquitous, portable smartphones. The research provides implications for retailers and policy makers, while offering avenues for future research.
