가치사슬은 경쟁우위 강화를 위한 전략적 도구로써 주로 기업수준, 산업수준에서 분석되어 왔다. 그런데 기업수준에서 가치사슬 분석을 수행하기 위해서는 분석 기업의 거래처 기업들이 그 기업의 가치 사슬에 속하는지의 여부에 따라 분류되어야 한다. 단일 기업에 대한 가치사슬 분류는 전문가들에 의해 원활히 수행될 수 있지만 다수의 기업을 대상으로 분류할 때는 많은 비용과 시간이 소요되는 등의 한계점이 따른다. 따라서 본 연구에서는 실거래 데이터를 기반으로 특정 기업의 거래처 기업들을 분류해서 가치사슬 기업을 자동적으로 도출해주는 모형을 제안하고자 한다. 총 19개의 거래 속성 변수를 실거래 데이터로부터 도출하여 기계학습의 입력 데이터의 형태로 가공하였고, 랜덤포레스트 알고리즘을 이용하여 가치사슬 분류 모형을 구축하였다. 자동차 부품 기업 사례에 본 연구 모형을 적용한 결과, 정확도 92%, F1-척도 76% 그리고 AUC 94%로 자동적 가치사슬 분류의 가능성을 확인하였다. 또한 거래집중도, 거래금액 그리고 거래처별 총 매출액 등과 같은 거래 속성들이 가치사슬에 속하는 기업들을 대표하는 주요 특성임을 확인하였다.

본 연구에서는 커피 전문점 고객들의 구매 의사 결정 메커니즘에 대해 살펴보고자 한다. 고객들의 재구매 의도를 형성하는 주요 선행 요인으로 고객 만족, 인지된 가치, 브랜드 이미지를 고려하였다. 인지된 가치는 다차원 접근법을 바탕으로 실용적 가치, 유희적 가치, 사회적 가치로 구분하여, 각 가치 요인들이 고객들의 구매 의사 결정에 미치는 영향을 살펴보았다. 제안한 연구 모형은 커피 전문점을 자주 방문한 232명의 대학생들을 대상으로 분석하였으며, LISREL을 이용하여 구조방정식 모형을 검증하였다. 연구 분석 결과, 제안한 연구 모형은 재구매 의도 분산의 67%, 고객 만족 분산의 73%를 설명하였다. 고객 만족과 브랜드 이미지는 재구매 의도 형성에 핵심적인 역할을 담당하였다. 그리고 실용적 가치와 유희적 가치는 재구매 의도에 유의한 영향을 미쳤지만, 사회적 가치는 재구매 의도에 부정적인 영향을 미쳤다.

This paper builds a system dynamics model analyzing first mover effect and growth strategy of online retailer, a major segment of B2C e-commerce. The dynamic model in this paper is calibrated to the online book market and Yes24.com as major test cases. The model consists of eight key value chain sectors. Five of these(Users, Site Operations, Human Resources, Financial Accounting, and Fundraising) are internal to the company, and three others(Market, Financial Market, and Relative Performance) are external to the company. With the model, this paper suggests research propositions representing positive feedback loops and negative feedback loops that lead to corporate growth and limits to growth according to dynamic causal relationships among eight key value chain sectors, and simulate these propositions.

This paper analyzes the impact of the recent change in global value chain on the productivity of manufacturing sectors and firms in Chungnam area using ADB MRIO. Forward participation significantly increases sector productivity in Chungnam area and backward participation affects the sector productivity after 2015. In the analysis for firm productivity in Chungnam area, GVC participation does not enhance the productivity of firms in Chungnam area. However, firms in the top 25% of productivity in 2007 improved their productivity with higher GVC participation and the productivity of firms in the top 25% of asset in 2007 was positively affected by forward pariticipation and negatively affected by backward participation. The productivity of firms that were in international market in 2007 was significantly worsened by GVC participation.

본 연구는 공급사슬 취약성의 동인과 내·외부 분열적 상황을 규명하고 공급사슬 위험관리가 성과 피해를 완화하는 조절효과를 검증하는 것을 목적으로 한다. 182개 중소기업을 대상으로 한 분석결과는 다음과 같다. 첫째, 공급사슬 취약성은 글로벌화, 제품 다양화 등 기업의 과도한 효율성에서 비롯되었음을 확인하였다. 둘째, 외부 환경적 분열요인보다 내부요인의 발생 가능성과 심각성이 더욱 높게 나타났다. 특히, 기업 내부의 가치사슬보다는 기업 간 공급사슬 프로세스에서 발생하는 위험의 대응 우선순위가 높았다. 마지막으로 공급사슬 위험관리의 수준이 높을수록 성과 피해를 긍정적으로 완화하는 조절효과가 나타났다. 본 연구는 공급사슬 위험에 대응하는 기업실무자와 정책 입안자의 의사결정에 실행적 단서를 제공하는 것에 가치가 있다.

The global cod market is supposed to have weak structure with a high dependence on the supply of Russia, the United States, Norway, and China. The COVID-19 pandemic has significantly disrupted the cod supply chain for the worse. Fish processing facilities in China stopped their operation, and cod demand declined due to shrinking consumption in Europe. The position of South Korea as an intermediary trade country between Russia and China strengthened due to the U.S.-China trade war and the Atlantic cod decrease in 2019. However, this global cod supply chain collapse has caused South Korea to export accumulated cod to Indonesia and Vietnam at a bargain price, showing that South Korea was unable to cope with this supply chain crisis. The primary purpose of this study is to investigate changes in the global cod supply chain and their impacts on the intermediary trade of South Korea caused by the COVID-19 pandemic. It also aims to provide implications by analyzing advanced cases in Denmark. As the cod supply chain crisis countermeasures, this study suggests that South Korea develop high value-added marine products, gain competitive advantages by solidifying the value chains of related countries, and activate export by discovering alternative markets in terms of the supply chain of the cod industry.

Coordination between supply chain partners is viewed critical to effective supply chain management. In many situations such as mutual investments or developing infrastructures for their operations related with each other, the coordination issue arises. Depending on the bargaining power balance between them, it is determined who will be able to exert more influence in making decisions related with such coordination. We consider two cases of the decision-making structure in the context of a simple supply chain consisting of two players, i.e., (1) the first case in which a supply chain partner dominates the decision-making process and the other passively follows the dominant player's decision, and (2) the other case in which the two players share the decision-making process equally. We examine which of the cases is better for the companies and where comes the value of the better case. To answer the research questions, we set up an optimal control theory model and derive an analytical solution. The analysis outcome indicates that the shared decision-making in general produces better results for both companies in the supply chain, and the value of the shared decision-making comes from more effective resource utilization than the dominated case.

This two-part study explores the changes in the types of perceived value and consumption channels for vintage clothing and the relationship between the two variables. In Study 1, we used text mining with the keyword "fashion+vintage." Emotional value was the most frequently mentioned, and environmental value increased the most. We also revealed an increasing trend in online channels for vintage clothing consumption. In Study 2, we analyzed 30 interviews with consumers who had purchased vintage clothing through online channels. We identified 7 attributes and 20 goals for vintage consumption online and pinpointed three strong connections. First, consumers reported high levels of service satisfaction due to the usefulness of algorithms. Second, the authenticity and heritage information available through online and mobile channels were associated with consumers' perceptions of value related to financial benefits. Third, consumers sought to find rare products through online channels, leading to a strong influence on their sense of achievement. Overall, this study proposed ways to increase the value of vintage clothing perceived by consumers through consumption online.

The aim of this study was to enhance the value of the chestnut industry by analyzing the value chain structure. Based on the value chain theory, it is divided into primary activities and support activities. Thus, in total, 27 subjects from Gongju, Buyeo, and Cheongyang were interviewed and self-administered questionnaire. Regarding the value chain structure of the chestnut industry, the primary activities consisted of production followed by cultivation and storing, sorting and packaging, transportation and marketing sales. The support activities were divided into production infrastructure, policy, R&D, and systematization. The primary activities are able to maximize profits through cost reductions. The production was divided into general and environmentally friendly cultivation. Depending on the labor force, it is family-centered labor. However, the installation of harvest nets depends on a hired labor force (40 - 60%) such that it would be necessary to have a mechanized harvest to replace the manpower for the cost reduction. Transportation, marketing sales, and backdoor selling (38.1%) were higher than the existing channels (31.0%) using the National Agricultural Cooperative Federation. The enhancement of value could be created by maximizing profits through the reinforcement of the links between each subject. The production showed strong connections with cultivation/storing, sorting/packing, and backdoor selling and the National Forestry Cooperative Federation. The processing stage is a very simple structure, it would be necessary to have R&D and to support promotions, infrastructure, machines, and sales increases, which should be expanded by connections with other industries like the food industry.
