Abstract

Purpose

The purpose of this paper is to find out how absorptive capacity (AC), leadership capacity (LC) and government support (GS) affect small and medium enterprises (SMEs) innovation (product innovation [PDI], process innovation [PCI] and distribution channel innovation [DCI]), taking into consideration the role of innovation (PDI, PCI and DCI) on competitive advantage and SMEs performance and the moderating role of customer orientation (CO).

Design/methodology/approach

This study gives a theoretical model tested using structural equation modeling. The information used to test the hypotheses came from interviews with the top managers of Vietnam’s SMEs. The 633 survey respondents from the southern part of Vietnam were chosen for the study. The goal of the 47-item questionnaire is to look at how all variables relate to each other.

Findings

The results show that a firm’s LC has the most significant impact on innovation, followed by its AC and GS. According to the study, DCI does not lead to competitive advantage but improves SMEs’ performance. In addition, the study’s findings indicate that CO moderates the relationship between PDI – SMEs performance and DCI – SMEs performance.

Research limitations/implications

The classification of only three types of innovation (PDI, PCI and DCI) restricted the applicability of the research to other kinds of innovation in SMEs. Second, only AC, LC and GS are identified in this study as external factors that influence business innovation. In this study, the authors have not studied different business industries; the authors recommend that the research in the back on SMEs should investigate their classification into distinct industry groups, including agricultural, forestry and marine products; industry and construction; and commerce and services.

Practical implications

This study shows the importance of innovation senior management for innovation in SMEs. This study found that innovation, especially continuous innovation, increased competitive advantage and SMEs performance. Companies that wish to innovate must have access to external resources and support. Moreover, enterprises must comprehend their consumers’ wants to achieve innovation and better SMEs’ performance.

Social implications

This research significantly contributes to enterprise innovation and operational efficiency for the sustainable development of SMEs in Vietnam. It is expected to enhance employment opportunities, maintain social stability and expand Vietnam’s gross domestic product.

Originality/value

This study contributes to the growing knowledge of the indirect and direct effects, the mediating function of innovation (PDI, PCI and DCI) on competitive advantage and SMEs performance and the moderating effect of CO.

Abstract

Purpose

Cambodian and Laotian students (CLS) are among the largest groups of international students in intra-ASEAN student mobility as well as in Vietnamese higher education institutions (HEIs). However, little has been researched on the factors influencing CLS’s decision to choose Vietnam as destination country. The purpose of this study is to investigate why CLS decide to go overseas and choose Vietnam as their host country among other opportunities as well as their perceptions of the decision.

Design/methodology/approach

Using qualitative methods and employing purposive sampling, data were collected by semi-structured interviews from CLS studying in a HEI in the Mekong Delta of Vietnam. The data were analysed against the push–pull framework to understand factors influencing the participants’ decision.

Findings

The findings show that CLS in the study were “pushed” by the perceived higher value of a foreign qualification and family encouragements. In terms of pull factors, they were attracted to choose Vietnam as the host country most observably due to scholarship opportunities. However other pull factors were also significant, especially the lack of certain skills in home countries and its congruence with Vietnam’s competitive strength in offering courses for those skills. In retrospect, the participants expressed a sense of optimism, though there was also certain reservation.

Research limitations/implications

The small sample restrict the generalisability of the findings.

Practical implications

As an exploratory study, the findings can lay the ground for largerscale studies investigating CLS mobility in Vietnam and be employed for inbound student mobility policymaking reference for HEIs in Vietnam as well as in other developing countries.

Originality/value

This study investigates why Cambodian and Laotian international students decide to go to Vietnam, a developing country in the lesser-known part of international student mobility landscape. This is a topic that remains under-researched in the Asia-bound student mobility literature. Insights from the study can not only contribute to the scholarly gap but also offer implications for HEIs in Vietnam and other Asian countries.

Abstract

Purpose

Data crawling in e-commerce for market research often come with the risk of poor authenticity due to modification attacks. The purpose of this paper is to propose a novel data authentication model for such systems.

Design/methodology/approach

The data modification problem requires careful examinations in which the data are re-collected to verify their reliability by overlapping the two datasets. This approach is to use different anomaly detection techniques to determine which data are potential for frauds and to be re-collected. The paper also proposes a data selection model using their weights of importance in addition to anomaly detection. The target is to significantly reduce the amount of data in need of verification, but still guarantee that they achieve their high authenticity. Empirical experiments are conducted with real-world datasets to evaluate the efficiency of the proposed scheme.

Findings

The authors examine several techniques for detecting anomalies in the data of users and products, which give the accuracy of 80 per cent approximately. The integration with the weight selection model is also proved to be able to detect more than 80 per cent of the existing fraudulent ones while being careful not to accidentally include ones which are not, especially when the proportion of frauds is high.

Originality/value

With the rapid development of e-commerce fields, fraud detection on their data, as well as in Web crawling systems is new and necessary for research. This paper contributes a novel approach in crawling systems data authentication problem which has not been studied much.

Abstract

Purpose

This paper aims to test a theory-driven model reflecting the effects of perceived personalization on consumer–brand relationships on social media.

Design/methodology/approach

The conceptual model is empirically tested through two studies using partial least squares-structural equation modeling. Other techniques, such as common method bias, multigroup comparison, mediation analysis and model fit comparison, are also used to give more insights into the analytical process.

Findings

Data from two studies show that perceived personalization is positively related to brand-related outcomes including brand self-expressiveness, consumer–brand engagement and brand connection. While consumer–brand engagement and brand connection are positively related to brand love, brand self-expressiveness is not.

Research limitations/implications

The paper contributes to the advertising and brand management literature by shedding light on a better understanding of the impact of personalization in the digital world.

Practical implications

Management could learn important lessons from personalization. If a strategy of promoting personalized ads is implemented successfully, those ads could change customer perceptions of brands which ultimately strengthens brand love.

Originality/value

This research provides an empirical model that helps marketers better understand the factors affecting brand love with personalized ads on social media.

Abstract

Purpose

In the digital age, organizations want to build a more powerful machine learning model that can serve the increasing needs of people. However, enhancing privacy and data security is one of the challenges for machine learning models, especially in federated learning. Parties want to collaborate with each other to build a better model, but they do not want to reveal their own data. This study aims to introduce threats and defenses to privacy leaks in the collaborative learning model.

Design/methodology/approach

In the collaborative model, the attacker was the central server or a participant. In this study, the attacker is on the side of the participant, who is “honest but curious.” Attack experiments are on the participant’s side, who performs two tasks: one is to train the collaborative learning model; the second task is to build a generative adversarial networks (GANs) model, which will perform the attack to infer more information received from the central server. There are three typical types of attacks: white box, black box without auxiliary information and black box with auxiliary information. The experimental environment is set up by PyTorch on Google Colab platform running on graphics processing unit with labeled faces in the wild and Canadian Institute For Advanced Research-10 data sets.

Findings

The paper assumes that the privacy leakage attack resides on the participant’s side, and the information in the parameter server contains too much knowledge to train a collaborative machine learning model. This study compares the success level of inference attack from model parameters based on GAN models. There are three GAN models, which are used in this method: condition GAN, control GAN and Wasserstein generative adversarial networks (WGAN). Of these three models, the WGAN model has proven to obtain the highest stability.

Originality/value

The concern about privacy and security for machine learning models are more important, especially for collaborative learning. The paper has contributed experimentally to private attack on the participant side in the collaborative learning model.

Abstract

Purpose

The purpose of this study is to analyze the relationship between public spending, budget imbalance and underground economy. In addition, this paper investigates how budget imbalance moderates the public spending–underground nexus.

Design/methodology/approach

By utilizing a data set spanning from 1995 to 2017 of 35 OECD countries, the study has employed Dynamic Common Correlated Effects (DCCE) approach. The study is also extended to consider the marginal effects of public spending on the underground economy at different degrees of budget imbalance.

Findings

The results indicate that an increase in public spending and budget imbalance contributes to the expansion of underground economy. Interestingly, the effects of public spending on the underground economy will enhance and intensify with a higher budget imbalance level. The results are robust to various specifications and their broader implications are discussed.

Practical implications

Governments should carefully implement a fiscal policy with a clear understanding that increasing public spending leads to the expansion of informality. Besides, policymakers should enforce supportive policies to boost economic growth, cooperation and cross-border trade to control the size of the underground economy.

Originality/value

This study stresses the role of public spending, budget imbalance on the underground economy in OECD nations. To the best of the author's knowledge, this study pioneers to explore the moderating effect of budget imbalance in the public spending–undergrround nexus.

Abstract

Purpose

The purpose of this study is to investigate the impact of government administrative capacity and e-government performance on the citizens’ intention to use e-government services by integrating into the technology acceptance model (TAM). In addition, the study investigates the mediating effect of perceived usefulness in these nexus.

Design/methodology/approach

A quantitative and cross-sectional approach is used to gather the data from 443 respondents in Vietnam. The squares structural equation modeling is used to access the impact of government administrative capacity and e-government performance on the citizens’ intention to use e-government, the mediating effect of perceived usefulness.

Findings

The results show that e-government performance, government administrative capacity and perceived usefulness are critical determinants of citizens’ intention. Furthermore, government administrative capacity positively impacts e-government performance. More importantly, perceived usefulness plays a mediating role in these relationships. The results also show that both age and qualification moderate the relationship between perceived usefulness and intention.

Practical implications

The findings of this study provide valuable evidence and implications. Public officials must enhance the administrative capacity as the determination for the application of e-government. They must demonstrate their commitment to implementing e-government initiatives. Moreover, the government should continually carry out policies to improve e-government performance.

Originality/value

This study uses the TAM by incorporating government administrative capacity and e-government performance. Evidence about the mechanism linking government administrative capacity and e-government performance to citizens' intention to use e-government is scant. With this stated, this study fills these gaps by pioneering exploring the mediating role of perceived usefulness in these relationships.

Abstract

Purpose

This paper aims to provide a deep understanding of rural household livelihoods in the Mekong Delta and to explore how they can cope with climate stressors at the ground level.

Design/methodology/approach

The paper employs the sustainable livelihood framework at a household and also an individual scale. The general data obtained from a survey of 2,100 households provide an overview of their livelihoods. Qualitative and quantitative methods were adopted, as case studies, to comprehensively assess 100 households in one commune affected by annual floods and an additional 100 households in another commune affected by sea level rises. Livelihood profile analysis is beneficial to identify specific livelihood change patterns that have taken place in these specific cases.

Findings

There are four types of livelihood adaptation to climate stressors: (1) change of structure of agricultural systems, (2) change of employment locations, (3) resettlement with strong impact on livelihoods and (4) out-migration. The household livelihood resources and the local economic structures have significant roles in driving adaptive solutions.

Research limitations/implications

This paper provides detailed profiles of the livelihood change considered as passive adaptation of smallholders in the Mekong Delta.

Originality/value

It contributes to the knowledge of rural households in multiple aspects with regard to how they cope with climate change via reflection on their livelihoods.

Abstract

Purpose

As an emerging novelty, knowledge hiding has received considerable attention in management literature. Drawing on conversation of resources theory, this study aims to investigate how knowledge hiding impacts job performance among employees through the mediating role of emotional exhaustion. This work further offers deeper insight into the moderating mechanism of psychological resilience in these relationships.

Design/methodology/approach

Three time-lagged sets of data (N = 362) were collected among employees in Vietnamese firms. The partial least squares structural equation modeling method was applied to test the research hypotheses.

Findings

Empirical findings indicate that knowledge hiding positively impacts emotional exhaustion. Furthermore, emotional exhaustion serves a mediating role in the link between knowledge hiding and job performance. The results also show how psychological resilience moderates the relations between knowledge hiding, emotional exhaustion and job performance.

Practical implications

The findings suggest that managers can reduce the harms of knowledge-hiding behaviors by enriching employees’ resources and bolstering their psychological resilience.

Originality/value

This inquiry explores the mechanism linking knowledge-hiding behaviors and job performance through the mediator of emotional exhaustion. In addition, this study extends the current knowledge by investigating the moderating role of psychological resilience in the relations between knowledge-hiding, emotional exhaustion and job performance.

Abstract

Purpose

Open social innovation has become a critical practice for firms competing in volatile markets. Simultaneously, the rise of digital technologies has opened opportunities across sectors, making digital transformation a key driver of corporate change. This study examines the impact of internal and external factors, such as social capital, absorptive capacity and government support, in facilitating open social innovation and digital transformation activities, which may ultimately enhance business performance.

Design/methodology/approach

Data were collected through a questionnaire survey distributed to management members across various enterprises in a wide range of industries in Vietnam. A total of 289 valid responses were obtained, and the research hypotheses were tested using partial least squares structural equation modeling.

Findings

First, open social innovation positively influences digital transformation, with absorptive capacity mediating this relationship. Second, social capital directly affects open social innovation and indirectly impacts digital transformation through open social innovation. Third, digital transformation directly enhances business performance, while absorptive capacity indirectly influences business performance through digital transformation. Finally, government support directly impacts business performance and indirectly influences digital transformation via open social innovation.

Originality/value

By integrating social capital theory and the resource-based view, this research significantly advances the understanding of the complex relationships among government support, social capital, open social innovation, digital transformation, absorptive capacity and business performance.
