Methodologically, we conducted an extensive review of 735 research papers on digital literacies to gather definitions and frameworks. As a result, we identified seven core constructs and three main proficiencies that constitute the platform literacy framework.

Informality is argued to be a drag on productivity growth in emerging & developing countries. We argue that increased use of digital technologies can help informal sector reduce transaction and coordination costs; enhance the linkages between the informal and formal sectors; facilitate the integration of the informal sector in the global value chain; and also increase the potential for the formalization of the economy in general - all of these are likely to contribute to aggregate productivity growth. Our econometric analysis using panel data for 118 countries from 1997-2017 provides some evidence of ICT capital deepening helping to reduce informality's negative impact on aggregate productivity growth. However, the moderating effect is modest compared to the magnitude of the negative impact of informality, indicating the need for a faster and more intense digitization efforts in emerging & developing economies. Moreover, investments in complementary factors including skills and infrastructure are imperative to fully unleash the potential of ICT in reducing the negative impact of informality.</p></div>","PeriodicalId":22290,"journal":{"name":"Telecommunications Policy","volume":"48 1","pages":"Article 102681"},"PeriodicalIF":5.6,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0308596123001921/pdfft?md5=9d3afc7e8b9949156f69756c1df054af&pid=1-s2.0-S0308596123001921-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138524475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present evidence from a field survey with an experimental component in Ghana. We show that, while hopes are much more pronounced than in advanced economies, opinions also change once people are exposed to new types of information. Using a ‘text as data’ approach, we also investigate reasons that explain the differences in attitudes and what people associate with digitalization. We conclude that, in Ghana, especially semi-formal, self-employed people hope that new technologies will allow them to leapfrog old ones that have historically been marred by market and government failures. Compared to developed countries, it is rather some of the higher educated to whom the negative consequences also have relevance.

However, because 6G technology has a very wide range of applications as a fundamental technology, 6G service scenario research is also being conducted for each sector. To predict 6G technology use in the future, it is necessary to understand comprehensively the scenarios being studied sporadically by sector. Therefore, we aim to derive major service scenarios by analyzing in-depth public data for 6G service scenarios. We collected research papers, corporate reports, and news articles on 6G service scenarios and performed topic modeling to derive four major domains and 16 application areas. Afterward, the derived service's feasibility and promising scenario were evaluated by utilizing the future-context canvas and business model canvas that analyze the service's value from the user's and supplier's perspectives, respectively. The research results are expected to support technology development and business planning in the field by enhancing understanding of 6G service scenarios.</p></div>","PeriodicalId":22290,"journal":{"name":"Telecommunications Policy","volume":"48 2","pages":"Article 102678"},"PeriodicalIF":5.6,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135514450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that the participating economies experience a significant rise in ICT development. A country's participation in the Digital Silk Road (DSR) in addition to the BRI further increases its ICT development and increases its participation in global ICT value chains relative to their BRI-only counterparts. Overall, the benefit of participating in the BRI on ICT development is enhanced by participating in the DSR. However, there are unequal trade creation effects between China and the rest of the world. The participating economies increase their imports of computer and information services more from and increase their imports of communication services less from China than from the rest of the world after the participation. These results are robust to a parallel trend test, alternative ICT measures and alternative estimation methods.
