세계보건기구(WHO)는 홍콩독감과 신종플루 이후 역사상 세 번째 팬데믹을 선언했다. 코로나19의 발생으로 국가 간 교류는 극도로 위축되는 한편 빠른 전염성으로 국가별 경기변동의 시간차를 만들어 냈다. 2020년 1월 미‧중 무역 분쟁은 합의국면으로 접어들었으나 코로나19로 발생한 경제 디커플링 현상은 중국이 미국과의 무역균형을 맞추기 어렵게 만들었고 미‧중 무역 분쟁 합의 조건을 지키기 어렵게 만들었다. 트럼프 대통령은 코로나19 확산의 책임을 중국에 돌렸고 경기 침체의 원인도 중국의 영업비밀 침해, 불법복제품 등으로 지목하면서 보호주의가 대두되었다. 이에 중국은 거세게 반발하면서 미국과 갈등이 깊어졌다. 미국은 중국 반도체 굴기의 핵심기업인 화웨이와 SMIC에 무역재제를 선언했고 미‧중 간 반도체 밸류체인 단절 위험을 예고하고 있다. 반도체 산업의 밸류체인 분리는 특정 국가와 기업이 가치사슬에 고도로 전문화되어 독점하는 구조인 반도체 산업에 큰 충격을 줄 가능성이 있다. 본 논문은 코로나19로 인해 재점화된 미‧중 간 반도체 밸류체인 단절 위험과 반도체 글로벌 산업 가치사슬의 충격과 변화, 한국 반도체 기업의 대응전략을 다루고자 한다.

Currently, domestic seaweed production is about 800,000 tons per year, which is the largest seaweed production in the world after China and Japan. However, most seaweeds (Pyropia ssp, Undaria pinnatifida, Saccharina japonica, etc) are consumed in the form of dried products or hot water extracts, and there are many difficulties in developing various products due to difficulties in the manufacturing process. Through the pulsed electric field treatment device, the extraction efficiency can be expected to increase compared to the convectional hot water extraction. Pulsed electric field technology is a non-heating treatment technology in which high-voltage electric energy is processed into cells in the form of pulses, affecting the potential difference of cell membranes, and performing collapse or perforation treatment. In this study, components such as protein and carbohydrate content were extracted by treating Saccharina japonica with PEF, and compared with the hot water extraction method, As a result of experiment at voltages of 0.7 and 1.5㎸ and pulse duration of 5㎲, the crude protein content increased by up to 42% and the sugar content increased by up to 30% compare to the hot water extraction. Higher efficiency results can be expected through optimization of several parameters that may affect the extraction process.

The aim of this study is to confirm the gap between customer-perceived value and supplier-perceived value in the manufacturing industry. The author empirically tested a structural equation model in a sample of 42 customers and 42 manufacturers. Findings confirmed the gap in the perception of value between customers and suppliers.

Markets are complex ecosystems consisting of various interconnected actors, in which resources are integrated to co-create value. Said value co-creation within markets can be enhanced by creating higher resource density, hence shaping the market. However, market shaping research predominantly focuses on the activities of market shapers, rather than the equally important roles of other market actors within the ecosystem. While market shapers are instrumental in the process of shaping, this narrow focus fails to consider how all market actors inevitably are influenced or influence the market ecosystem. All market actors exert effort in the value co-creation process, including the process of market shaping. This study therefore explores effort in a market shaping context and examines the effects of effort reduction as a mechanism to facilitate market shaping as it leads to enhanced value creation. This is a conceptual study that uses theory adaptation approach to link the concept of value co-creation, market shaping, and effort. This study offers a conceptual framework and five propositions outlining the role of effort reduction in the value co-creation process with flow on effects to market shaping. The developed conceptual framework indicates how market shapers can enhance resource density and increase value creation by reducing the effort required of other market actors in the value co-creation process. This research offers effort reduction in the value co-creation process as a viable market shaping tactic and extends the focus beyond the focal market shaper to consider the broader context with numerous market actors within it.

The purpose of this study is to explore the value structure of sharing economy for consumers, and to construct a model of consumers' continuoususe intentionin the sharing economy. Firstly, based on the characteristics of sharing economy platform technology, this paper explores the composition of platform value (time adaptability, location adaptability, content accessibility) through qualitative analysis. Then through quantitative analysis, this paper explores the influence of platform value on consumers' perception of emotional value and economic value. Finally, on this basis, this paper studies the impact of consumer value of sharing economy on consumer behavior, and compares and analyzes the impact of consumer value of sharing economy on consumers under different product types. In short, this paper aims to study the value creation of sharing economy from the perspective of consumption value, and shape its future development direction.

This study examines new value proposition presented in promoting environment-friendly residential facility. Relationship among changes in social background, consumers’ intention/ value and solar PV systems introduction is evaluated over the last decade since before the Great East Japan Earthquake.

This paper discusses the influence of QR codes on consumers’ purchase decision in green advertising. We found that QR codes can improve advertisement value, perceived green value, and green trust. This relation eventually leads to a positive influence on consumers’ purchase intention.
