4차 산업혁명은 모든 산업 분야에서 제품 및 서비스와 ICT가 융합되어 공급사슬의 효율성을 극대화하는 혁신을 일으키고 있다. 이러한 혁신을 통해 공급사슬 내 기업들의 관계가 변화하고, 기존 제품 및 서비스와는 차별화된 혁신적인 제품 및 서비스가 출시되고 있다. 또한 혁신 주체의 공급 사슬 내 역할에 따라 혁신이 기업 및 소비자에게 미치는 영향은 달라질 수 있다. 본 논문에서는 하나의 제조업체와 하나의 유통업체가 존재하는 공급사슬 모형을 가정한다. 이러한 공급사슬에서 1) 제품 및 서비스의 차별화 정도와 2) 혁신의 주체의 공급사슬 내 역할(제조업체 또는 유통업체)에 따라 혁신의 영향이 달라질 수 있음을 보인다. 또한 이를 바탕으로 4차 산업혁명 시대에 선도적 혁신과 관련된 실무적 시사점과 정책적 시사점을 제시한다.

This paper analyzes the long-run effects of an environmental tax levied on motor vehicles. If the government charges their consumers the tax as much as the monetary value of the external damage due to the pollutants emitted from motor vehicles, the operation of vehicles is reduced to the socially optimal level, alike to ordinary Pigouvian taxes. Thus, air pollution abatement is realized in the short run. Moreover, in the long run, the tax leads the consumers to prefer cleaner vehicles owing to the tax burden, and so the firms produce the motor vehicles with less pollutants emitted to meet the change of demand. Therefore, the tax has the additional effect on air pollution abatement. This result is obtained from the simulation in the oligopoly model which has an interior solution when the vehicles are horizontally and vertically differentiated.

A green market for a product refers to the market where the more willingness to pay for the product consumers have, the greener is the product. As the green markets begin to spread out, researches have been carried out mostly on the effects of various environmental policy measures such as unit emission standard, environmental taxes as they are applied in the green markets. This paper focus on a different issue in the green markets, that is, the effects of the greener market on pollution emission. We consider two kinds of markets, which are fully or partially covered. In the fully covered market where the products sold are necessities such that all consumers purchase the product, as the market gets greener, the amount of pollution emission decreases. On the other hand, in the partiaily covered market, it is shown that the amount of pollution emission could increase as the market becomes greener. This critically depends on whether the total output decreases or increases as the market turns greener.

This study is to analyze Gwangju's trade structures with China, Japan and the United Sates, and to contribute, through clarification of product competitiveness, to minimizing free-trade-induced costs as well as maximizing profits from free trade. To obtain this study purpose, two export competitiveness indicators are used; they are Trade Specialization Index (TSI) and Grubel & Lloyd(GL) Index. Intra-industry trade is examined to see if there exists a technological gap between nations. Intra-industry trade is divided into two; Low Quality Vertical Intra-Industry Trade (LQVIIT) and High Quality Vertical Intra-Industry Trade (HQVIIT). Gwangju's trade with China is HQVIIT; Gwangju exports high-quality and high-priced items to China, and imports low-quality and low-priced ones. On the other hand, Gwangu's trade with Japan is mainly LQVIIT; Gwangju exports low-quality and low-priced processed stuffs to Japan, and imports high-quality and high-priced ones from Japan. While Korea-US is mainly of both high-quality and low-quality Vertical Intra-Industry Trade; Gwangju exports low-quality and low-priced items as well as high-quality and high-priced items to the USA. Based on the analysis result, export marketing strategies are presented as follows: the transition to high value-added export system, the local entry networking, government support for trade exhibition, offer of special program on local small businesses.

A green market refers to a market that consists of environmentally aware consumers. A few researches have been carried out on the effects of environmental policy measures in a green market. These existing researches were based on a vertical differentiation model with firms' price-setting behavior, and derived that unit emission standard and environmental product taxes could not reduce the amount of pollution emission. This note considers a vertical differentiation model with firms' quantity-setting behavior, and shows that, contrary to the previous result, the amount of pollution emission is reduced by the introduction of unit emission standard. This implies the importance of the nature of firms' interaction in figuring out the pollution abatement effect of environmental policy measures in a green market.

IT기술의 발전과 스마트기기의 대중화로 인한 정보통신기술의 눈부신 발전으로 온라인 플랫폼을 통한 식품구매 비중이 급격히 증가하여 온·오프라인의 경계를 없어지고 있다. 더군다나 COVID-19 팬데믹은 반조리식품, 밀키트 등 홈쿡(Home-cook) 온라인시장을 급격히 확산시키며 소비자 구매추세를 오프라인에서 온라인으로 완전히 바꿔놓는 전환점이 되었다. 이런 트랜드를 반영하듯 다양한 온라인 식자재 이커머스 플랫폼의 출현하면서 브랜드마다 각각의 차별점을 내세우고 있으나 경쟁은 치열해지고 차별화는 더욱 어려운 게 현실이다. 이는 기업이 소비자에게 일방향으로 정보 또는 상품 및 서비스를 제공 하는 수직적 관계가 아닌, 수평적 쌍방향 관계로의 발전으로 이어져 브랜드가 가지고 있는 가치에 대해 보다 정직하게 보여주어야 소비자의 신뢰를 얻을 수 있게 되었다(Kotler, 2017). 또한, 과거에 소비자들의 만족도가 높았던 서비스도 현재 환경에서는 소비자의 니즈를 충족시키지 못하는 경우가 증가하고 있다(조윤오, 2018). 이는 서비스에 대한 소비자의 기대와 니즈가 지속적으로 변화하고 있다는 것을 의미하며, 이에 따라 기업은 소비자들의 새로운 요구를 만족시키기 위하여 다양한 서비스를 개발 및 제공하는 것이 중요하다고 사료된다(김광재 등, 2011). 이미 높은 인지도를 가진 플랫폼일지라도 지속가능한 우위를 선점하기 어려운 상황에서 온라인 플랫폼에 대한 소비자의 긍정적인 태도와 재구매를 유도하기 위해 제품 본질 뿐 아니라 서비스 차별화를 꾀하고 있고 차별화된 포지션을 차지하기 위해 온라인 플랫폼에 대한 소비자 인식과 서비스 품질 요인을 측정하여 고객이 중시하는 요인에 집중하는 것이 필요하다. 이에 본 연구는 온라인 플랫폼을 통해 식자재를 구매하는 소비자의 꾸준한 방문과 구매를 유인하기 위해 어떤 변수의 영향력을 높여야 소비자 재구매의도를 증가시킬 수 있는지 방법을 모색하고 온라인 플랫폼 기업 및 스타트업의 경영전략 마련에 목적이 있다. 이를 위해 식자재 구매 플랫폼 품질속성, 서비스품질 정도,, 충성도의 전반적인 영향관계를 파악하는 연구 과제를 설정하고, 식자재 이커머스 온라인 플랫폼 이용 전반에 대한 평가를 실시할 예정이다. 이러한 과정을 통해 도출된 결과는 식자재 이커머스 플랫폼 운영 전략을 세우는데 유용한 자료가 될 것이라 기대하며, 기존의 온라인 식품구매 플랫폼의 서비스품질 요인과 소비자 행동 간의 관계를 설명하는 것과는 다른 새로운 시사점을 제공할 수 있다는 측면에서 의미 있는 연구가 될 것이다. 또한, 다양한 산업에서의 플랫폼 비지니스 모델 적용을 위한 전략 수립을 하는 데에 필요한 기초자료를 마련하고자 한다.

In this paper, we study the bargaining strategy of a distributor who sells vertically differentiated, i.e. high and low brand products. We derive and analyze the equilibrium solutions for both simultaneous and sequential bargaining games among the distributor, the high brand product manufacturer and the low brand product manufacturer. The result shows that the optimal bargaining strategy for the distributor heavily depends on the relative quality and price level of the low brand product comparing to those of the high brand product. It is also shown that, for more bargaining profit, the distributor has strong motivation to prefer a low brand product which has lower quality level per unit price.

The increased availability of store brand suppliers now provides retailers with opportunities to create their own lines of vertically differentiated multiple store brands within a product category. As the number of store brands increase, the retailer's shelf space becomes more crowded, which may force the retailer to consider dropping some national brands from its assortment. Despite these trends, the problem of product line design in a vertically differentiated product category has been analyzed mainly from a manufacturer's perspective in the marketing literature and it is not known to what extent the findings of the existing product line design literature provide applicable strategic guidelines for the new problem faced by retailers. In this study, we address this deficiency in the literature and conduct an in-depth study of the retailer's strategic design of a line of store brands and its assortment decision within the context of retail category management. We analyze the retailer's decision about not only how to design a line of store brands but also which national brand to drop from its assortment. The results of our analysis are as follows. First, if the retailer has to drop one of national brands from its assortment, it is the best for the retailer to drop the low-quality national brand rather than the high-quality national brand. Second, the retailer has to position the high-quality store brand relatively close to the high-quality national brand, remained on its shelf, in terms of quality so as to maximize the size of retail margin from the national brand. On the other hand, the retailer should set the quality of the low-quality store brand at a lower level than that of the low-quality national brand to increase the total category demand by attracting more price sensitive consumers. By doing so, the retailer can also minimize cannibalization between two store brands. Lastly, our analysis shows that the introduction of a line of store brands improves consumer welfare by increasing real values of all products on the shelf.

This study examines the economic effects of a developed country's minimum quality standards (MQS) and mutual recognition agreements (MRAs) between countries. Based on the results of such analysis, it also considers the optimal MRA strategy for South Korea. For this purpose, the paper constructs a simple three-country model in which the representative firms in each country supply differentiated goods to the developed country market. The analysis results are as follows: First, the rise in the MQS of a developed country intensifies the competition level, reduces the profits of all firms, and raises the developed country's consumer surplus. In addition, if one of the firms exits the market due to the MQS, competition is relaxed, and the profits of the remaining firms increase. Second, countries subject to MQS can improve their social welfare through the MRAs; thus, it is essential to utilize them strategically. In the case of South Korea, the optimal situation is to have an MRA with the developed country or for all three countries not to have any MRA.
