This paper empirically investigates the impact of global value chain (GVC) participation on environmental pollution using data from China's manufacturing sector. A new Environmental Performance Index (EPI) is introduced as a proxy for assessing changes in environmental pollution. The key findings are as follows: Firstly, although total factor productivity (TFP) in China's manufacturing sector has not shown recent improvement, green total factor productivity (GTFP) has increased. This finding suggests an improvement in environmental quality. Secondly, an increase in the degree of GVC participation is associated with greater environmental pollution. Thirdly, an increase in the GVC position index across all industries in China contributes to a reduction in environmental pollution, suggesting that as production moves upstream, environmental quality tends to improve. Fourthly, however, in the case of energy‐intensive industries, this reduction in environmental pollution was not evident. These findings highlight the importance of directing governmental policies toward promoting forward GVC participation rather than backward participation, particularly for reducing environmental pollution. However, it is crucial to note that for energy‐intensive industries, shifts in GVC position toward the upstream may not necessarily result in environmental improvements.

Purpose: This study aims to explore how the relationship between information-seeking and infection-prevention behaviors through risk perception changes according to the level of trust in the media and government. Methods: The study is a secondary data analysis of data from a cross-sectional national survey of 700 adults living in the community, representing different age groups, genders, and geographic regions. A validated questionnaire was used to assess information-seeking behaviors, trust in media and government, and risk perception to explain infection-prevention behaviors in response to the COVID-19 pandemic. A conditional analysis was conducted using SPSS and PROCESS macro (Model 7) to identify the effect of moderated mediation. Results: The participants were fairly balanced by gender and age group. Most participants learned about COVID-19 through major broadcasts and television (56.7%) followed by internet media (21.7%). Information-seeking and risk perception together explained 17% of the variance in infection-prevention behaviors (F=63.95, p< 0.01). The standardized indirect effect (β=0.04, BootCI 0.02, 0.06) was significant at 95% CI. The moderated mediation index (M=− 0.04, CI − 0.05, − 0.01) indicates that trust in media and government influences the effect of information-seeking on risk perception and infection-prevention behavior even after controlling for age and gender. Conclusion: Information-seeking behaviors affect infection-prevention behaviors directly and indirectly through risk perception. Trust in media and government modulates this relationship, emphasizing the importance of establishing trust to promote effective risk communication and long-term public compliance with infection-prevention practices. Health authorities should focus on building trust through transparent risk communication and integrating diverse media perspectives. Further research is needed to explore the psychological and social mechanisms underlying trust in media and government through qualitative, cross-cultural comparisons.

In response to the evolving e-commerce landscape, the study investigates changing patterns of social networking site (SNS) usage during a pandemic. Grounded in the interaction of the person-affect-cognition-execution model for addictive behaviors and the appraisal and coping theory, it explores the depth and extent of SNS usage. Specifically, the study examines the moderated mediating effect of perceived stress (PS) and fear of missing out, with risk mitigation behavior as a moderator. With data from a nationwide survey in Korea with 760 responses, results show that risk mitigation behavior moderates the relationship between infection threat and PS, while PS and fear of missing out mediate the effect of infection threat on SNS usage. The moderated mediation of PS was significant, shedding light on the complex psychological mechanisms that drive SNS behavior during global crises. The findings deepen understanding of how stress and coping strategies shape SNS engagement in response to crisis.

In this study, we investigate Indian anti-dumping (AD) duties imposed on eight products (Harmonized System classification) from Bangladesh over the period 1998–2020. Using the Poisson pseudo-maximum likelihood method, panel regression analysis is applied to examine the relationship between Indian AD duties and goods imported from Bangladesh. Our results provide weakly suggestive significant evidence of trade destruction in the full sample, though statistical significance is enhanced for all product groups other than lead-acid batteries at the product-level investigation. We also provide suggestive evidence for trade diversion from AD duties. Overall, our results show Indian AD duties to be correlated with a decrease in imports from Bangladesh, and an increase in imports of goods from other, unnamed countries. This suggests that India’s protectionist measures may have been ineffective in protecting local producers, as any adverse effects of protectionism on Bangladesh may be offset by import diversion to other foreign suppliers. We also discuss the policy implications of these findings.

Since China joined the World Trade Organization (WTO) in 2002, the number of technical barriers to trade (TBT) notifications has increased rapidly. This study investigates the impact of China’s imposition of TBTs on the exports of Korean manufacturing-industry from 2002 to 2014. We focus on the following aspects: exports in terms of value-added, a comparison of exports of final goods with exports of intermediate goods, and specific trade concerns (STCs). Our findings are as follows. First, China’s TBTs have an insignificant impact on Korean manufacturing exports to China when we investigate the whole manufacturing industry sector. Second, as a result of analyzing final goods and intermediate goods separately, we do not find a significant effect of TBTs on the export of intermediate goods, whereas they have negative effects on the export of final goods. This is in line with our expectations that China does not want to restrict the import of intermediate goods. Third, further analysis of the relationship between exports and TBT STCs is conducted. However, we find no additional negative effect of TBT STCs on exports. Fourth, the impact of TBTs on exports in value-added terms does not seem to differ from the impact on total gross exports.

This study explores the impact that TBT and SPS measures have on 42 countries domestic value-added exports (DVAs) into the US. The results from this empirical analysis show that both TBT and SPS measures have no significant effect on gross exports, however, TBT measures have a significant inhibiting effect on DVAs, indicating that the traditional gross trade estimation approach underestimates the substantial impact of non-tariff measures on trade gains. To be specific, a 1 percentage point increase in TBT measures leads to DVA exports decrease of 2.37%. Moreover, the negative impact is mainly manifested in developing countries and high-technology products.
