The transformation of natural resources across the economy in China, South Korea, and Vietnam has been studied to give a comparative regional perspective based on trends in resource efficiency, bilateral trade dynamics, and progress on regional economic and environmental policy. Consumption of raw materials has been decomposed into economic dynamic...

... By diverting stock fabric from landfills and incineration, the textile industry can reduce environmental pollution, preserve land resources, and promote sustainability [6]. Figure 1 highlights the global distribution of waste, underscoring the urgency to reduce waste generation [6]. Additionally, the economic benefits of upcycling stock fabric are emphasized, considering the heavy reliance on imported textiles and raw materials by textile-producing countries [7]. ...
This study utilized SEM to examine the fiber structure of cotton stock fabrics and tested their durability based on ISO standards. Two types of cotton stock fabrics were evaluated: natural-colored (162 cm width, 120.8 g/m ² weight, 281/10 in × 252/10 in density) and black-colored (157 cm width, 136.1 g/m ² weight, 482/10 in × 210/10 in density). Prolonged water immersion caused surface yarns to loosen, fibers to expand, and the cross-sectional area to increase. Residual pulp and impurities on the fabric adhered to fibers. After 27 days, fiber looseness peaked, leading to complete breakdown after 30 days. Natural-colored fabric experienced significant weft strength loss within 12 days, while black fabric showed slightly higher weft strength loss after 36 days. Color changes were prominent in natural-colored fabric during the initial 21 days, while black fabric displayed noticeable changes after 12 days of immersion.
... As of 2022, China (21.9%), the USA (13.5%), and Vietnam (6.1%) accounted for 41.6% of Korea's total imports and exports. Imports and exports to the top three countries mentioned above greatly influence the Korean economy [73,74]. Japan has been South Korea's primary trading partner. ...
Industrial crises exert considerable influence on a wide range of industries, national economies, and global economic landscapes. The primary objective of this study is to devise a crisis index specifically tailored for the petroleum sector—a vital component of South Korea’s energy industry. An exhaustive analysis of the existing literature was conducted to extract pertinent elements and indicators, and indicator weights were determined using the analytic network process (ANP). Moreover, a combination of qualitative and quantitative methods was employed to rigorously evaluate the validity of the proposed crisis index. The implications derived from this study offer critical insights for stakeholders into the petroleum industry and demonstrate the potential applicability of a crisis index framework for other industries.
... Moreover, Vietnam is heavily dependent on Chinese raw materials and equipment for manufacturing, which is a problem for its exports (Huong & Shah, 2021). In the labor-intensive textile and capital- ...
China has been losing international competitiveness in labor‐intensive industries due to various factors, including the trade war with the United States and globalization. Vietnam, however, has rapidly expanded its labor‐intensive exports. The paper proposes to explore the future of labor‐intensive industries in Vietnam due to the U.S.‐China trade war. The paper examines export performance data from United Nation Comtrade for 10 specific labor‐intensive industries that serve the U.S. market between 2000 and 2020 to assess the possibility of Vietnam overtaking China's position as the world's largest manufacturer. Using situation analysis, the paper compares the competitive advantage of Vietnam in labor‐intensive industries due to the U.S.‐China trade war. The paper found that China's competitiveness was negatively impacted for the final two periods, while Vietnam's competitive advantage increased.
Purpose
This study aims to ascertain whether technological diversification (TD) enhances firm performance and explores the effect of patent portfolio balancing (PPB) on firm financial performance and the moderating role of research and development (R&D) intensity.
Design/methodology/approach
This study empirically investigates a panel dataset based on 296 information and communications technology (ICT) small and medium-sized enterprises (SMEs) over 5 years, using a fixed-effects panel regression with time-lagged and moderating effects. Data are collected from a government survey and a firm and patent database.
Findings
The relationship between PPB and return on assets (ROA) is negative, indicating that TD in SMEs adversely affects firm performance. R&D intensity positively moderates the relationship between PPB and ROA, implying that follow-up R&D after creating new patents could weaken the negative relationship between TD and firm performance. This moderating effect only occurs when R&D intensity is sufficiently high, suggesting that high R&D firms could be more successful at diversification.
Practical implications
As TD consumes many resources, managers should set the optimal level of diversification and recognise the need for follow-up R&D for successful diversification.
Originality/value
This study conceptualises a unique theoretical framework for the PPB of ICT SMEs, revealing the moderating role of R&D intensity in changing the negative influence of PPB on firm performance.
