Abstract
Mobile payment (m-payment) enables consumers to perform their payment tasks via a mobile technology platform. In this study, we summarized, evaluated, and expanded upon the literature about m-payment usage intention by synthetically integrating the advantages of three information systems theories into an integrated model, which details the complementary relationship between the objective measures, subjective perception of m-payment services, and m-payment technology–task fit characteristics. Based on a sample of 908 individuals in two different Kakaopay user groups (467 Chinese Kakaopay users in Korea and 441 local Korean Kakaopay users) and the three-model integrated optimization, we integrated the unified theory of acceptance and use of technology model (UTAUT), the information systems success model (D&M ISS), and the task-technology fit model (TTF), considering moderating variables (Chinese and Korea experienced consumers) and multi-group analysis. We chose the factors influencing Chinese and Korean consumers' usage intention as the research objects, and ultimately achieved our purpose of more accurately predicting consumer behavior patterns to expand the scale of potential Chinese consumers. The empirical results theoretically contribute to academic and practical solutions for the Korean m-payment product and help technology suppliers to stimulate the sustainable growth of Korean mobile payment consumer groups in Korea.
Highlights
The world economy has a three-tiered world pattern, with the European Economic Area, the Free Trade Area of the Americas, and Asia-Pacific Economic Cooperation (APEC) as the centers
As a comprehensive financial platform with a considerable scale in the Asia-Pacific region, Kakaopay has the following sustainability characteristics: Higher electricity supplier penetration, financial support and financial transactions integrated with cryptocurrencies like bitcoin and Ethereum, and joint services support with Alipay, which will provide 450 million Chinese and Korean consumers in the foreseeable future [6]
Considering the advantages of online questionnaires, such as their low cost, ability to provide fast feedback, wide-coverage, and lack of a time limitation [66,67,68], the second group of about 200 participants was recruited from the Kakaopay after-sales information feedback center, who had bought e-ecommerce products using Kakaopay
Summary
The world economy has a three-tiered world pattern, with the European Economic Area, the Free Trade Area of the Americas, and Asia-Pacific Economic Cooperation (APEC) as the centers. The Korean exports indicator is called a canary in the coal mine, as a barometer of global economic growth [1]. According to the data compiled by Statistics Korea in 2018, among all the South Korean export growth (SKEG) Indicators, the total amount of Korean online shopping transactions increased to $0.096 trillion USD (ranked fifth in the Organization for Economic Co-operation and Development (OECD) nations), generating 6.27% of the Korean GDP ($1.53 trillion USD), showing significantly more sustainable characteristics than the ratio of Korean traditional manufacturing trades, such as the automotive manufacturing trade (4.0%) and the shipment trade (1.3%). The sustainable growth of Korean mobile payment (m-payment) as an essential part of the SKEG indicators is crucial for the sustainable economic growth of Korea and the world.
