Abstract
Purpose
The purpose of this paper is to identify variables and their effects on the value of technology transaction according to technology demand approach in Vietnam technology market, by testing the hypotheses including the effects of technology absorption capacity, internal research and development (R&D) productivity of firms and difficulties in external infrastructure on technology demand.
Design/methodology/approach
The technology transaction value and its impact factors are assessed using Vietnam annual enterprise survey and using technology in production survey from 2012 to 2016. The effects of factors on value of technology transaction are determined by using feasible generalized least squares model.
Findings
The results indicate three main points. First, companies having higher technology absorption capacity and higher dominance in the domestic or foreign markets tend to acquire higher technology demand in the technology market. Second, companies having lower internal R&D productivity tend to require higher external technology demand. Finally, higher level of difficulty from external infrastructure prevents enterprises in accessing technology demand.
Research limitations/implications
The main limitation of the study is that data of firm’s R&D productivity are not available. The study also does not mention information flows from competitors that perhaps have potentially significant impacts on external technology demand of firms.
Practical implications
The paper includes policy implications for the government and industry managers to increase technology transaction value.
Originality/value
The focus of many previous research papers on technology transactions was generally to look at the decisive factors behind firm’s technology supply in both developed and developing countries. However, knowledge about firm’s technology demand is very limited, particularly in the context of developing countries. This paper clarifies the effect of factors on the decision buying external technology for innovation purpose and productivity improvement in Vietnamese manufacturing sector.

This paper aims to examine whether foreign technology acquisition is complementary to internal technology development in the context of a developing country.
Abstract
Purpose
This paper aims to examine whether foreign technology acquisition is complementary to internal technology development in the context of a developing country.
Design/methodology/approach
The selection model developed by Heckman (1979) was applied with the balanced panel data of manufacturing enterprises from the Annual Enterprise and Technology Surveys from 2012 to 2016 conducted by the Vietnamese General Statistics Organization.
Findings
The results indicate that foreign technology acquisition and internal technology development are complementary innovation options. Particularly, the number of patents granted for manufacturing enterprises positively affects the probability that enterprises acquire foreign technologies. This effect is stronger in cases of high-tech industries than in cases of low-tech industries.
Research limitations/implications
Regarding the relationship between internal technology development and foreign technology acquisition, the findings suggest that adoption of foreign technology acquisition and priority in budget allocation for foreign technology acquisition are different in nature and that budget allocation is a more complex issue and may depend on other factors.
Practical implications
For developing countries, governments should adopt policies supporting domestic enterprises in acquiring technologies from advanced countries that could complement the locally developed technologies. These supports should focus on the high-tech or high-innovation rate industries.
Originality/value
In the context of a developing economy, the complementary effect of internal technology development and foreign technology acquisition is stronger in cases of the high-tech industries than in cases of the low-tech industries.

Abstract
Purpose
This paper investigates the key determinants affecting household spending for university degree in Vietnam. This paper serves as empirical evidence for policymakers to select appropriate factors to estimate financial needs for university students in Vietnam.
Design/methodology/approach
We employ an innovative variable selection approach with adaptive LASSO for Tobit Regression Model.
Findings
The results suggest income, region and ethnicity play significant roles in determining higher education expenditure at Vietnamese households. Gender-related indicators (such as gender of household head, student’s gender), distance to school, occupations, etc. are empirically insignificant.
Originality/value
This study proposes a data-driven method by interfering regulation and Tobit regression to understand the divergence in higher education spending. Especially, adaptive LASSO was first introduced to identify key determinants of higher education expenditure at household level in Vietnam. It hopes to tackle over-fitting problems of traditional OLS regression in previous literature.

Abstract
Purpose
Climate change increases systematic risk for firms, especially those in the agricultural industry. Therefore, the need to examine the consequences of climate-related risks on agribusiness companies' financial performance across the globe and emerging markets has risen. In this context, the paper aims to investigate the effects of climate change risks on the financial performance of agriculture listed firms in Vietnam.
Design/methodology/approach
The study sample includes 77 Vietnamese listed firms in the agricultural industry in the period of 2015–2019. The authors chose temperature, wind, rainfall and humidity proxies to measure climate change. The OLS regression, random regression and sub-sample analysis have been used to examine the impacts of climate risks on firms' financial performance.
Findings
Empirical results show that rain and temperature have positive impacts on financial performance of Vietnamese agriculture listed firms, while wind and humidity have insignificant impacts on financial performance.
Research limitations/implications
The research helps researchers, businesses, practitioners and policymakers interested in the agricultural industry, especially those in developing and emerging countries, to develop a deep understanding of the impact of climate change risks on firm performance and therefrom prepare necessary measures to reduce the negative impacts.
Originality/value
This study adds to the literature stream on the impacts of climate change on financial performance. It is the first study to investigate this impact in Vietnam, a country which depends mainly on agriculture.

Abstract
Purpose
To achieve business success in a competitive market, hospitality firms are urged to search for different ways to enhance the firms' innovation capabilities. Drawing on dynamic capability theory, this study examined the role of entrepreneurial leadership in promoting product and process innovation through the mediating effect of innovation strategy and the moderating effect of knowledge acquisition.
Design/methodology/approach
Data were collected through a time-lagged (two waves, two months apart) survey from 137 managers and 322 employees working in 103 Vietnamese hotels. Structural equation modeling (SEM) was used to test the proposed hypotheses in our conceptual model.
Findings
The findings revealed that entrepreneurial leadership is positively associated with both product and process innovation. In addition, these relationships are mediated by innovation strategy. While the relationship between innovation strategy and product innovation is moderated by knowledge acquisition, evidence was not obtained for the moderation effect of knowledge acquisition on the link between innovation strategy and process innovation.
Originality/value
The findings advance innovation and leadership literature by identifying the roles of entrepreneurial leaders in managing an organization as a dynamic system and developing appropriate innovation strategy to adapt to rapidly changing environments. In addition, this study offers important implications for hospitality firms that are investing in innovation activities and are seeking ways to promote the firms' innovation of products and processes.

Abstract
This chapter provides information on the development of Vietnamese education under the influence of global forces based on the analysis of relevant education research and policies using Wolhuter’s frameworks. In the process of coming up with ways to develop education in the face of different influences of globalization, besides having reactions with patterns commonly found in countries around the world, Vietnam also has responses that reflect its own political, sociocultural and economic characteristics. The state still plays a controlling role in education at all levels and many culture-related features that have existed throughout the country’s history have hardly changed, namely aspects related to teachers, learners and teaching and learning methods. To sustain its education in the globalized era, Vietnam must make more efforts in various aspects such as the link between education and employment, the logic of education objectives, the feasibility and appropriateness of curricula, quality of education, especially of higher education and equality in education for underprivileged groups.

This paper aims to design a PD controller for an active suspension system to improve the car’s moving smoothness.
Abstract
Purpose
This paper aims to design a PD controller for an active suspension system to improve the car’s moving smoothness.
Design/methodology/approach
The controller parameters are optimized by an in-loop genetic algorithm (iL-GA). Unlike previous studies that only used conventional GAs to tune coefficients for the controller, the iL-GA designed in this paper provides outstanding efficiency when determining the optimal value range for the system. The optimal value range of parameters is determined by the in-loop algorithm based on criteria related to systematic errors. The optimal values are then calculated by the GA based on this range instead of an uncertain one.
Findings
Simulation results show that vehicle body acceleration and displacement values are significantly reduced when using the active suspension system compared to the conventional passive suspension system. The phase difference phenomenon does not occur in the iL-GA situation. In addition, the frequency domain investigation also shows the system’s stability when using iL-GA instead of conventional GA.
Originality/value
To the best of the authors’ knowledge, this is a new application that provides positive effects to the suspension controller. This algorithm can be applied to tune coefficients for direct controllers in the future.

Abstract
Purpose
Drought and salinity intrusion aggravated by climate change threaten agricultural livelihoods in Viet Nan's Mekong Delta. In response, authorities have built water management infrastructure for irrigation and salinity protection. This study assessed the impact of one such project, the Ba Lai dam in Ben Tre province, on the livelihoods of aquaculture farmers.
Design/methodology/approach
This study uses the Sustainable Livelihoods Framework to assess the impact of the Ba Lai dam on the livelihood capitals of 18 farming households in four communes, located both upstream and downstream of the dam.
Findings
The authors find that, apart from some positive effects, the dam has also brought negative environmental consequences, such as increased water pollution. The authors also find that farmers have responded to the changes by adapting their livelihood practices.
Research limitations/implications
The samples were relatively small, encompassing four communes in Ben Tre province. On the other hand, this case study is instructive to the many ongoing infrastructure projects in the Vietnamese Mekong Delta.
Social implications
The project have caused an increase in water-related social conflict.
Originality/value
The case of the Ba Lai dam provides a cautionary example for infrastructure-based water management plans, both in Viet Nam and more broadly. The study suggests the need to strengthen community participation and prioritize impacts of farmers' capital assets when constructing water management infrastructure for climate change adaptation.

Abstract
Digital marketing is becoming the dominant marketing communication method for companies and consumers around the world. The reason for this is due to the real time communication advantages that make it an effective marketing method. The aim of this chapter is to focus on how digital marketing relates to social entrepreneurship in Vietnam, thereby offering a new perspective on the role of social entrepreneurship in developing digital marketing techniques. This will contribute to the existing literature on digital marketing and social entrepreneurship by extending it to an emerging economy setting. Implications for practitioners and policymakers are given that highlight the need for more social enterprises to incorporate digital marketing techniques.
