Third-party payments were first introduced by the US firm PayPal. Soon after, China developed a localized version of PayPal – Alipay, which became the main payment method for online transactions in China. Currently, the number of global transactions conducted with Alipay is three times that of PayPal. In addition to online transactions, Alipay also integrates with mobile payment applications to provide offline services, making physical transactions more convenient for users. The authors, in this paper, aim to address how third-party payments technology seems to be playing out an innovation-imitation-catch up story.

Krugman (1966) proposed a general-equilibrium model of product cycles under perfect competition where high-tech products are innovated by an “advanced” country and imitated by a “developing” country. The competition between US–China online technologies (e.g. third-party payments) seems to be playing out this innovation-imitation-catch up story.

The USA has already put a lot of effort into the operations of credit cards and checks, as well as other infrastructure such as human resources and installation of relevant systems. China lacks the infrastructure for payments made with credit cards and checks, and therefore China’s opportunity cost of moving directly from cash transactions to third-party payments is much less than that of the USA, which is why China holds follower advantage in third-party payment markets.

The third-party payment technologies appear to be a good example of the argument made by Krugman (1966) regarding the US–China competition on advanced technology, which states that an imitator can catch up with an inventor when the former acquires comparative advantages against the latter.

This study examines the role of user psychological empowerment (PE) as a specific type of PE in the context of using health information systems (HIS) and incorporates the contribution of autonomous motivation and knowledge sharing intention (KSI) to the resolution of the key dynamics of interpersonal knowledge sharing behavior (KSB) in healthcare organizations.

For the data analysis, survey data were collected from 350 employees at three large teaching hospitals in Taiwan. In this study, the partial least squares technique was used with SmartPLS 3.3 software to validate the research model.

User PE had significant positive effects on autonomous motivation, KSI and KSB. Additionally, autonomous motivation positively affected KSB directly and indirectly via KSI.

Insights into motivation (e.g. user PE and autonomous motivation) play a key role in driving KSI and lead to effective KSB, which aids managers in tailoring their efforts to foster knowledge dissemination and enhance organizational performance.

While finding ways to encourage employees to share knowledge with one another in an organization is an important task, there exists a lack of understanding as to how this task can be accomplished in the context of healthcare organizations. This study is the first to specifically address this issue from a perspective integrating PE and self-determination theory while also incorporating the HIS context with population-specific measures (healthcare organizations) to expand the application of empowerment theory to the information system domain.

The rise of the metaverse has brought profound changes to the economic and social operation models and injected new vitality into academic research. Although a large number of studies have emerged, there are few quantitative analyses of development frontiers and trends.

From a bibliometric perspective, this paper selects 183 pieces of metaverse-related literature in the WoS core database since 2000 as the object of analysis. This paper sums up the characteristics of the literature using the methods of descriptive statistical analysis, keywords analysis, thematic evolution analysis and summarizes the core themes and the laws of metaverse development in each stage.

The digital economy vision brought by the metaverse has led to an increasing number of researchers and achievements in this field. But the depth and breadth of research are still insufficient and unevenly distributed in the region, and the cross-fertilization fields need to be expanded. From the industry's point of view, VR games represented by Second Life and My World have contributed to the popularity of the metaverse. As technology progresses, the research hotspots in the field of metaverse gradually develop from conceptual research to artificial intelligence, blockchain, NFT and other technical applications. However, academic research has not yet caught up with the industry's pace and stays more in the concept discussion and preliminary application stage.

A systematic overview of the current status, knowledge structure and hot issues of metaverse research is shown, which provides a thematic axis for this field, enriches and improves the quantitative analysis of its literature and provides a clear picture for researchers to continuously promote the development of this field. At the same time, it is necessary to warn that technological development is a double-edged sword. The process of metaverse development should return to rationality, respect the laws of its development and guarantee the healthy development of the metaverse by strengthening legal regulation and the ethical review of science and technology.
