Financial technology (fintech) services have come to differentiate themselves from traditional financial services by offering unique, niche, and customized services. Mobile payment service (MPS) has emerged as the most crucial fintech service. While many studies have addressed the essential role of security when service providers and users choose to engage in financial transactions, the relationship between users distinct perceptions of security and MPS success determinants are yet to be examined. Thus, this study primarily aims to uncover the distinctive roles of platform and technology security by investigating how users react differently to their varying understandings of the MPS usage environment. This study proposes a research model comprising two security dimensions (platform and technology) and three MPS success determinants (convenience, interoperability, and trust). We evaluated the proposed model empirically by using an online survey of 356 users. The survey accounts users experiences of the selected MPS. The results show that a security driven MPS can essentially enhance or deteriorate users positive perceptions of MPS success determinants while they use it for financial transactions. To further understand how this recent trend of user perception of security affects the overall MPS usage experience, this study provides theoretical insights into the roles of platform and technology securities. Managerial insights on the design strategies of MPS providers are also provided based on the potential implications of users subjective and objective perceptions of MPS security environment.

We principally focus on evaluating the local and entire network performance of railway stations for sustainable logistics management in South Korea. Specifically, we aim to address the issue of dealing with vulnerability in logistics dependent on the degree of connectivity. To resolve this issue, we investigate (i) the current level of local railway station sustainability performance from the perspectives of the value of the station (node) and the geographical location (place), and (ii) how railway station network management can prepare for imminent internal and external risks. Integrating node–place analysis and social network analysis approaches, we demonstrate a means of assessing (i) local railway station performance by comparing how one station’s value differs from that of other stations, and (ii) overall railway network performance by measuring the degree of connectivity based on the centrality characteristics. Consequently, we recommend improvement in planning orders considering the degree of local performance and network vulnerability for railway station network sustainability.

The existing approaches to identification of emerging technologies create a prominent opportunity for technology convergence and market growth potential. However, existing approaches either suffer from the time lag issue or have yet to explorethe assessment’s uncertainty and ambiguity. Based on a total of 14 years of mergers and acquisitions (M&A) activity data in the Health Care sector, the complex patterns between growth velocity and accelerating of M&A activities are analyzed with two quantitative indicators (Promising Index and Promising Index Sharpe Ratio) to identify emerging technological opportunities. The proposed integrative approach offers a mean to resolve the time lag issue, deal with market trend irregularity, and manage expectations of investors for emerging technology and industry. Specifically, this study aims to (i) provide a decision support system integrating M&A activity information for strategic investment planning and (ii) identify promising technologies in the Healthcare sector to manage the irregularities of market trend and investment outcome. This study is one of the first research that employs a prior data-based approach to delineate emerging technologies by analyzing the growth momentum properties of specific industry areas based on the M&A activity data.

An absence of trust among partners can magnify the risk in a complex project by increasing behavioural uncertainty. Partnership trust can effectively substitute for control, reducing variability of outcomes and increasing value-adding strategic collaboration. It is introduced as strategic countermeasures against risks associated with project complexity that can only be achieved with commitment from all partners. This research conceptualises partnership trust on four dimensions and investigates the roles of dedicated investment and information sharing in partnership trust–commitment. The complexity of trust management is further highlighted in an exploration of the importance of the exchange relationship environment.

This study aims to enable a high level of coordination to cope with increasing levels of uncertainty by computing supplier- and network-based resilience values. Our case study is based on a real-world highly connected global manufacturing firm based in Korea as a test environment to evaluate a proposed bicriterion network resilience model using resilience and network values, together with an ordering approach. An outranking methodology is used to determine the improvement priorities of suppliers to achieve a high level of overall network resilience. The results show that the effectiveness of a firm’s performance with respect to the entire supply chain may increase or decrease based on its embeddedness and connectivity within the supply network. This study is one of the first to provide an integrative (resilience capabilities and network attributes) approach to the supplier improvement model, future studies are encouraged to expand the model to different network settings.

Government legislation significantly impacts closed-loop supply chain (CLSC) operations. This study examines the collection rate of and decisions on the product greening improvement level in a three-level CLSC with the government’s reward–penalty and a manufacturer’s subsidy policy. Four game-theoretic models are analyzed in order to evaluate the ways in which the policy and revenue-sharing contracts (RSCs) between the manufacturer and retailer affect the CLSC members’ optimal decisions and profits. We found that a reward–penalty and subsidy policy raise the collection rate, as well as the product greening improvement level. A manufacturer’s financial conflict of interest can be mitigated using RSCs. The RSCs between the manufacturer and the retailer also increase the profit of a recycling company that successfully coordinates the CLSC. An interesting result is that, when the RSCs are used under the subsidy policy, the collection rate is higher than it is in a centralized model. We also found that the subsidy level needs to be adjusted according to the price of the recycling resources, and that increasing the value of the recyclable resources and lowering the recycling costs in the early stages of the supply chain collaboration could lead to higher environmental sustainability. These results illustrate that using an RSC can effectively coordinate the CLSC, and can thus help policy implementation by governments.

Understanding a supply chain (SC) leader’s role from a collaborative capability management perspective offers insights into strategically managing exchange relationships during disruptions. This study illustrates the importance of leadership responsibility in managing overall resilience capabilities among SC network members. Using insights drawn from leadership theory, SC leader-member exchange (LMX) is operationalised to measure levels in exchange relationships. Furthermore, an integrative probabilistic-reliability management approach is applied to explore the impact of SCLMX on SC network resilience performance. The findings reveal (i) the significant role a buyer’s leadership can play in improving SC capabilities; (ii) the asymmetric roles of different capabilities in resilience improvement; and (iii) the need to further investigate the relationship between SC capabilities and resilience based on disruption phases. This study presents a novel and useful theoretical model for investigating the role and value of SC leadership in complex SC network collaboration.

This study investigates the correlation between mergers and acquisitions (M&As) activities and industry-level performance. While extensive research on M&As has focused on financial performance at the firm-level around the merger announcement, not much focus has been given to the relationship between M&A activities and financial performance at the industry level. Using global data from the S&P (Standard & Poor’s) Capital IQ platform database, this study examines the significance of relationships of 12 industry-level financial values with M&A frequency and transaction value across 11 industry sectors throughout 2009–2018. The results show that M&A activities play a key role in identifying industries with lots of potential and that strategic investment planning can be drawn from both industry and time lag perspectives. This study bridges the gap by exploring the complexity of M&A performance across various firms and industries, and supports forward-looking investment processes by delineating emerging industries with expected positive returns.

Blockchain technology developed as a technical platform for electronic money. It is now considered a next generation information technology tool for sustainable growth in supply chain (SC) management. However, its study is relatively rare in the literature on SC collaboration and sustainability management research, despite its advantages in sustaining connectivity and reliability among SC partners. This study investigates how the use of blockchain in SC activities can influence (increase or decrease) SC partnership efficiency and growth, thereby affecting SC performance outcomes. Specifically, this study empirically validates a measurement and structural equation model with 306 SC experts from various industries. The findings show that the blockchain technology characteristics (information transparency, information immutability, and smart contracts) have significant positive effects on partnership growth and marginal effects on partnership efficiency. Though partnership growth has a positive effect on firm performance, partnership efficiency shows a negative effect.

The purpose of this study is to systematically identify and design improvement planning for supply chain resilience (SCRES) for a higher level of sustainability and a competitive advantage. Literature-based interpretive structural modelling (ISM), a pairing of the systematic literature review (SLR) and ISM approaches, is proposed for investigating and identifying a set of key performance measures of resilience for supply chain (SC) management. In line with previous research, we identified and updated 13 key SC capabilities out of 24 as core performance measures of supply network resilience. Furthermore, our findings categorised each capability and element into one of four types of influential power variables (drivers, dependent, autonomous, or linkage). This study (i) lends support to and updates previous research that examined the core capabilities of SCRES and (ii) provides complementary classifications for the influential powers of SCRES capabilities and elements. The literature indicates that there has been no research that has integrated SLR as a basis to ISM for an effective way to utilize existing studies for increasing awareness and developing managerial guidelines to achieve SCRES.

With increasing numbers of nodes and links in supply network relationships, understanding partnership management and the required level of collaboration is important for sustainable supply network alignment. This study explores the impact of partnership orientation on partnership commitment and firm performance using a model based on social capital theory and resource dependence theory. It aims to understand the appropriate partnership orientation for the desired level of commitment and firm performance, including innovation, operational, and financial performance. Using a survey of 423 respondents representing three different partnership structure types (supplier, buyer, and parallel-aligned firms’ perspectives), the relationship between partnership orientation and commitment in enhancing firm performance is investigated using structural equation modeling. Additional analysis identifies the moderating role of commitment and investment exchange on performance. The findings show that positive relationships between both investment and contractual-based partnership orientation positively contribute to partnership commitment, but the direct association between partnership commitment and firm performance type varies by partnership structure. Furthermore, (i) investment exchange level moderates the relationship between commitment and innovation and operational performance regardless of partnership structure type, (ii) negative investment exchange signals higher firm performance from the buyer firm’s perspective, and (iii) positive investment exchange is absolutely necessary for financial performance from the supplier firm’s perspective.

Mobile commerce, or m-commerce, has quickly become a powerful, indispensable approach for diverse business to consumer (B2C) industries to secure technology-oriented, risk-taking N-generation customers. However, their behavioral preferences have not been investigated in-depth, as most practitioners believe m-commerce consumers are merely a frontier group of e-commerce consumers, and not unique service consumers with distinct characteristics. This study examines m-commerce consumers’ unique behavioral aspects by conducting thorough theoretical research based on an integrated framework that includes the IS success, web satisfaction, and B2C channel preference models. We first construct an integrated model to analyze the fundamental roles of information system quality in an m-commerce context. A set of hypotheses are then tested and studied to verify the moderation effects of ubiquity, localization, personalization (mobile attributes), and cognitive effort (system barriers) on the newly established relationships. The statistical results are obtained using a survey data of 503 consumers with m-commerce service experiences in Korea, a leading m-commerce country. Finally, the results are analyzed and interpreted to identify m-commerce consumers’ perceived service quality levels, as well as their comparative differences against e-commerce consumers. We believe that both researchers and practitioners will benefit from this research, in that it not only isolates a prioritized list of key determinants of m-commerce success, but also highlights the necessity of continuous research effort regarding future market orientations.

This study investigates the impact of three institutional pressures, namely government, customer, and competitor pressures, on the environmental and operational performance of firms. These three institutional pressures are examined by implementing green supply chain management, considering the role of top management and studying social capital between buyers and suppliers in the supply chain. Data were collected through an electronic mail survey from buyer firms in the manufacturing industry in Korea. With 241 complete and usable responses, we used structural equation modeling to test our hypotheses. Our findings revealed that the majority of our hypotheses were supported, which is in line with the existing literature. However, the impact of coercive pressure on top management support and the impact of structural social capital on performance were found to be insignificant. The major contribution of our study is that it broadens the framework of green supply chain management (GSCM) by integrating major and recent constructs in the GSCM theory, while also providing instructive managerial implications through empirical evidence.

We evaluated the nosocomial outbreak of Middle East Respiratory Syndrome (MERS) Coronavirus (CoV) in the Republic of Korea, 2015, from a healthcare operations management perspective. Establishment of healthcare policy in South Korea provides patients' freedom to select and visit multiple hospitals. Current policy enforces hospitals preference for multi-patient rooms to single-patient rooms, to lower financial burden. Existing healthcare systems tragically contributed to 186 MERS outbreak cases, starting from single "index patient" into three generations of secondary infections. By developing a macro-level health system dynamics model, we provide empirical knowledge to examining the case from both operational and financial perspectives. In our simulation, under base infectivity scenario, high emergency room occupancy circumstance contributed to an estimated average of 101 (917%) more infected patients, compared to when in low occupancy circumstance. Economic patient room design showed an estimated 702% increase in the number of infected patients, despite the overall 98% savings in total expected costs compared to optimal room design. This study provides first time, system dynamics model, performance measurements from an operational perspective. Importantly, the intent of this study was to provide evidence to motivate public, private, and government healthcare administrators' recognition of current shortcomings, to optimize performance as a whole system, rather than mere individual aspects.
