Through its superior technical characteristics compared to previous generations of mobile technologies, 5G supports the development of innovative services and products across the whole economy. As a consequence, the potential impact of 5G is frequently described as being significant, with estimates of $1 trillion or more being added to global GDP by the end of the decade being common. For mobile operators, 5G provides an opportunity to generate new sources of revenue. This would boost their revenues, and thus their market capitalisations which have fallen in recent years as value has migrated to other parts of the digital economy. In this paper we argue that mobile operators face a number of inter-woven challenges that will shape their ability to utilise 5G to generate new sources of revenues. These reflect the multi-faceted role that 5G will play in today's economy, where it is both a service in its own right but also one that enables the delivery of other services. Not only may users be unwilling to pay a premium for 5G, but as it is used in other sectors the role of mobile operators is thrown into doubt. Local licences question the role of and need for mobile operators, who may find providing 5G-enabled services to vertical industries difficult due to the nature of these sectors.</p></div>","PeriodicalId":22290,"journal":{"name":"Telecommunications Policy","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138821179","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}

This study used the data from UN COMTRADE to construct ICT services trade networks spanning from 2004 to 2020. Using complex network analysis methods, it delved into several aspects of ICT services trade, including trade patterns, trade relationships, and participating countries. The findings revealed that central countries in ICT services trade are progressively dominating trade relationships. Moreover, many countries in the middle and lower tiers of the ICT services trade system tend to engage in bilateral trade with major economies or form trade alliances with a select few nations. Examining the evolution of trade participants, early adopter countries such as the United States, Ireland, and the United Kingdom have solidified stable competitive advantages in ICT services trade. Building upon these findings, the study puts forth several recommendations to enhance the competitiveness of the ICT services trade. This study not only enriches the existing knowledge base on ICT services trade networks but also provides valuable insights for shaping policies in this domain. The outcomes offer crucial guidance for interpreting cooperation and conflicts within the realm of ICT services trade.</span></p></div>","PeriodicalId":22290,"journal":{"name":"Telecommunications Policy","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2023-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138562398","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}

Firstly, the scale of Vietnam's core economy has increased rapidly over the past 14 years. In 2007, the share of the core economy in GDP was only 1.45%. In 2019, this number increased to 7.08%. Second, the scale of Vietnam's digitalized economy grew significantly from 2007 to 2019. In 2007–2011, the digitalized economy accounted for 4.90% of GDP. This number increased to 11.56% for the period 2016–2019. Third, the growth of the digitalized economy is mainly based on the growth of the core digital economy. Therefore, the digital spillover effect in Vietnam's digitalized economy during the 13 years has only slightly changed.

Both regimes also emphasize application agnosticism and end-user choice, with European law finding the former implicit in the latter. At the same time, European and U.S. law reflect some key differences: the regimes cover different types of entities, frame the issues in terms of nondiscrimination versus throttling and paid prioritization, take different positions on whether measures must be limited to temporary or exceptional circumstances, and place different weight on the impact of the rules on investment and on the relevance industry standards.
