This study aims to explore the situations and socio-economic and health-related factors associated with employment of older men and women in Vietnam.

This study used the nationally representative data in 2019 with a sample size of 3,049 older persons (those aged 60 and over). This study applied logistic regression analyses.

This study found that there were significant differences in employment rates between various groups of older men and women in terms of age group, residential place, marital status and educational level. Controlling for age, education, marital status, place of residence and (in) sufficient income for daily living, the results from logistic models indicated that health issues were strongly associated with lower probability to be employed for both genders. In all tests and regression models, that age and health condition were consistently related with lower employment probability of older persons implied an important consideration in raising normal retirement ages for both men and women.

Due to limitation of the cross-sectional data, this research could not explore how health influences older people’s employment overtime.

Findings of this research provide important and adaptive policy insights for Vietnam to take advantage of older workers for economic growth under an aging population.

To the best of the authors’ knowledge, this has been among the first studies exploring the role of health, which was presented by different indicators, determining employment of older men and women in Vietnam.

The main purpose of this paper is to explore whether the nature of innovation is accumulative or radical and to what extent past year accumulation of technology stock can predict future innovation. More importantly, the authors are concerned with whether a change of policy regime or a variance in the quality of technology will moderate the nature of innovation.

The authors examined a dataset of 3.6 million Chinese patents during 1985–2015 and constructed more than 5 million citation pairs across 8 sections and 128 classes to track knowledge spillover across technology fields. The authors used this citation dataset to calculate the technology innovation network. The authors constructed a measure of upstream invention, interacting the pre-existing technology innovation network with historical patent growth in each technology field, and estimated measure's impact on future innovation since 2005. The authors also constructed three sets of metrics – technology dependence, centrality and scientific value – to identify innovation quality and a policy dummy to consider the impact of policy on innovation.

Innovation growth is built upon past year accumulation and technology spillover. Innovation grows faster for technologies that are more central and grows more slowly for more valuable technologies. A pro-innovation and pro-intellectual property right (IPR) policy plays a positive and significant role in driving technical progress. The authors also found that for technologies that have faster access to new information or larger power to control knowledge flow, the upstream and downstream innovation linkage is stronger. However, this linkage is weaker for technologies that are more novel or general. On most occasions, the nature of innovation was less responsive to policy shock.

This paper contributes to the debate on the nature of innovation by determining whether upstream innovation has strong predictive power on future innovation. The authors develop the assumption used in the technology spillover literature by considering a time-variant, directional and asymmetric matrix to model technology diffusion. For the first time, the authors answer how the nature of innovation will vary depending on the technology network configurations and policy environment. In addition to contributing to the academic debate, the authors' study has important implications for economic growth and industrial or innovation management policies.

This policy paper compares the performance of state-owned enterprise (SOEs) versus private firms in selected emerging economies in Asia, focusing on a number of performance indicators. The indicators are internationally recognized quality innovation, product and/or service innovation, financing of operations, dealing with government regulations and labor performance. To the best of the authors’ knowledge, there has been no such comparative study for these indicators between SOEs and private firms and across countries. Most studies of SOEs have been national case studies. As such, they give us little knowledge of how a country compares with other countries at similar stages of economic development. A cross-country comparative analysis can help us identify broader trends and patterns.

The authors compare and discuss the performance of SOEs versus private firms in a number of emerging Asian countries, namely China, India, Indonesia, Malaysia and Vietnam. To do so, the authors use data from the 2018 World Bank Enterprise Survey (which is the latest available) for the period 2012–2015. The authors focus on a number of key performance indicators, namely internationally recognized quality innovation, product and/or service innovation, financing of operations, dealing with government regulations and labor performance.

The comparative analysis uncovers some interesting differences between the two types of firms. For example, somewhat surprisingly, SOEs tend to innovate more than private firms. However, the single most significant pattern the authors find is that in middle-income Asia both types of firms face formidable challenges with respect to doing business – e.g. scarcity of relevant training programs for employees. Therefore, the priority of policymakers must be to improve the overall business environment for all firms, regardless of their ownership structure.

The nature of this paper is a policy paper. This is because the data used in this study is survey data, conducted every four–five years (or more) for each country in the study and available for very few countries. As the data are not available for a continuous period of time, The authors could not conduct empirical research for this topic and thus made it a policy paper that presents a comparison across Asian countries as case studies.

The five selected Asian countries are interesting case studies for a comparative analysis since they are middle-income countries where SOEs play a significant role in the economy. Furthermore, state ownership is an important institutional dimension in emerging markets, and strong ties with the government can influence the performance of SOEs through various market and non-market channels. Despite the potential importance of the research theme, there is very little existing research on cross-country comparisons of the performance of SOEs vis-à-vis private firms. This could be explained by scarce data availability. With this in mind, the study attempts to shed some light on SOEs' performance and add to the rather limited literature.

This chapter investigates the impact of the euro crisis on Asia’s short-term economic outlook. This chapter tries to answer this question by examining both the trade and financial channels of crisis transmission. More specifically, it looks at the effect of euro crisis on Asian exports and growth, contagion from EU financial markets to Asian financial markets, and influence of EU bank lending on credit growth in Asia. The chapter also touches upon Asia’s policy space to assess how well the region is positioned to weather another major external shock. This chapter finds that the impact of euro crisis on developing Asia points to a sizable but manageable short-term impact. Furthermore, our analysis points to a significant effect on the region’s financial systems, especially its banking sector. This chapter informs policymakers of the impact of the euro crisis and advice to continue to keep a close eye on eurozone developments and their ramifications for their economies.

This paper examines global imbalance and rebalancing issues from the viewpoint of Korea. As IMF (2009) notes, the unwinding of global imbalance seems inevitable and, in fact, it is in progress. We illustrate that Korea, with a flexible exchange rate system and relatively balanced current accounts, has little direct linkage to global imbalance. However, we also find that Korea is not immune to the costly adjustment process of imbalance due to the triangular trade between Korea, China and the U.S. The fact that Korea is ‘indirectly’ linked to global imbalance limits Korea’s ability to cope with the situation. Boosting domestic demand, often mentioned recommendation for East Asia, is not an appropriate solution for Korea with low personal savings rate. A lot depends on China’s policy. If China reduces its dependence on U.S. market and increases domestic consumption despite unemployment risk in export manufacturing sector, it will provide Korea with an opportunity for more stable growth based on China’s final demand. Korea can also make efforts to increase economic integration and expand monetary cooperation in Asia that would help to increase consumption demands and final goods trade in the region.

This study aims to investigate the evolution of eight Asian countries’ innovation policy instruments during three economic development phases. Another goal is to examine common and different policy instruments of Japan, Korea and China, which have already reached the post-catch-up stage, to provide lessons to less-developed and developing Asian countries.

This study uses a qualitative research methodology, in particular a narrative approach. For triangulation, this paper uses a wide range of secondary data. The authors selected eight Asian countries by using various criteria, including income level and market size, and examined each country in terms of innovation performance and evolution of innovation policy instruments. The evolution of innovation policy in each country is investigated during three economic development phases: pre-industrialization, industrialization and catch-up and post-catch-up.

The findings show, first, that a higher research and development (R&D) expenditure as a percentage of gross domestic product (GDP), R&D activities dominated by private research organizations and more vigorous patent activities by residents than nonresidents are the most critical factors for becoming a high-income country. Second, innovation policy should be suitable for attaining aims, which are different at each economic development stage. Third, seven lessons from three prosperous Asian countries are crucial for economic development: securing political stability; increasing R&D expenditures; facilitating the acquisition, diffusion and internalization of technology; encouraging government–industry–university collaborations; using the selection and concentration strategy; changing the governmental role from regulator to facilitator; and establishing a legal framework.

It is difficult to find research that systematically compares three or more Asian countries’ innovation policies over the long term. This study fills this gap and helps scholars and field workers increase their understanding of innovation policy in eight Asian countries. It also contributes to providing lessons for practitioners that could help developing and less-developed Asian countries establish a suitable innovation policy for each economic development stage.

This paper aims to improve the load capacity of gas foil thrust bearing (GFTB) and to introduce and study a novel bearing with stacked bump foils.

For the proposed novel GFTB supported by stacked foils, some bump-type gaskets with several partial arches are inserted below the regular bump foil, and the height of each arch can be made differently. These features make the bump foil thickness and height gradually increase, which can bring enhanced support stiffness and convergent film at the trailing edge. Based on a new nonlinear bump stiffness model considering bump rounding and friction force, the finite element and finite difference method were used to solve the coupling Reynolds equation, energy equation and foil deformation equation. Finally, the structural stiffness and static characteristics of the novel GFTB were gained and compared with the traditional bearing.

The novel GFTB has an additional convergence effect in the parallel section, which improves the static performance of bearing. The bearing capacity, friction moment, power loss and temperature rise of the novel GFTB are all higher than those of the traditional bearing, and the static characteristics are related to the parameters of stacked bump foils.

The stacked bump foils bring a fundamental enhancement on the load capacity of GFTB. The results are expected to be helpful to bearing designers, researchers and academicians concerned.

The purpose of this study is to explore green supply chain management (GSCM) practices and their relationship with organizational performance. More specifically, this research explores the effect of GSCM efforts and other organizational factors on firm performance of small and medium enterprises (SMEs) that serve as suppliers to large customer firms in the electronics industry.

This study developed a research model relating GSCM practice and business performance through three organizational variables (employee satisfaction, operational efficiency, and relational efficiency) as moderators. Statistical analyses were based on the data collected, through survey questionnaires, from 223 SMEs in the electronics industry in Korea. Reliability, validity, and goodness‐of‐fit of the research model were tested by the widely accepted statistical tools. To test the hypotheses relating GSCM practice implementation and business performance, structural equation modeling was used.

The most anticipated finding of the study was a direct link between GSCM practice implementation and business performance. However, no statistical significance was found. Instead, significant indirect relationships were found between GSCM practice implementation and business performance through mediating variables of operational efficiency and relational efficiency. This result indicates that business performance will be improved when GSCM enhances operational efficiency and operational efficiency.

Research on GSCM is still at the early stage. Further refinement of the questionnaire is needed. Generalizability of the findings is also limited because of data collected from electronics firms in Korean. This study shed several important insights. The findings of this study are generally consistent with prior studies in other parts of the world. SMEs in the Korean electronics industry believe that GSCM practices help generate new opportunities to attract clients in addition to complying with the buyer firms' demand. It was also found that implementation of GSCM practices help improve operational and relational efficiencies of supplier firms.

Few empirical studies have been done in GSCM based on the conceptual footing of resource dependence theory. Also, this study was conducted from the supplier's perspective in examining the weaknesses of SME suppliers. Thus, the authors emphasize the importance of support from large buying firms for improving SME suppliers' green management capabilities.
