This paper considers the value of warehousing contract under probabilistic demands. We consider a supply chain consisting of a supplier, a retailer and its third-party warehousing partner who provides the warehousing service to the retailer through an outsourcing contract. A typical contract is specified by initial space commitment and modification schedule. The retailer decides the order quantity for the supplier and space commitment for the outsourcing contract. Since there is close relationship between order quantity and space commitment to minimize the total cost including ordering cost, inventory carrying cost, shortage cost, and warehousing cost, we develop an analytical model under probabilistic demands, where the retailer can determine the optimal order size and space commitment level jointly. We found the closed-form optimum for a single-period case and the optimal conditions for a two-period case. To evaluate the value of contract flexibility for the two-period case, we compared the total cost under two policies; one with modification, under which the base commitment can be changed at the start of each period and the other without modification. From results of our numerical analysis, we showed that the modification policy is more cost-effective as the variability of demand increases.

어느 때보다도 불확실해진 시장환경과 더욱더 복잡해지는 소비자의 요구는 신제품 개발의 중요성을 증대시키고 있다. 하지만, 점차 좁아지는 기술격차와 빨라지는 제품의 수명주기는 기업들로 하여금 외부조직과 연합을 통해 부족한 지식을 보완하는 현상을 가져왔다. 그러나 이러한 현상은 다른 조직과 지식의 교환과 조합이란 새로운 문제를 부각시키게 되었다. 신제품을 개발하기 위한 지식의 교환과 조합을 통해 가치있는 지식을 만들기 위해서는 지식 수령자의 흡수역량이 중요하게 고려되어야 하지만, 동시에 지식 전달자의 특징인 지식보호성향도 놓쳐서는 안된다. 하지만 이러한 요소를 동시에 고려한 연구는 매우 제한적이었다. 본 연구는 신제품 공동개발 과정에서 공급자의 흡수역량과 구매자의 지식보호성향이 신제품 개발성과에 어떠한 영향을 미치는지 알아보았다. 더불어 공급자의 흡수역량과 구매자의 지식보호성향의 상호작용효과에 대해서도 연구하였다. 이를 위해 신제품 공동개발이 자주 발생하는 자동차산업, 전자산업, 방위산업을 대상으로 자료를 수집하였으며 조절회귀분석으로 통계적 검증을 실시하였다. 연구결과 공급자의 흡수역량은 신제품 개발성과와 긍정정 관계가 있었으며, 구매자의 지식보호성향은 신제품 개발성과와 부정적 관계가 있는 것으로 밝혀졌다. 아울러 공급자의 흡수역량과 구매자의 지식보호성향이 신제품 개발결과에 상호작용 효과를 갖는 것으로 나타났다. 이러한 결과는 신제품 공동개발 시 공급자의 흡수역량이 중요한 요소로 작용하지만, 우수한 흡수역량을 가진 공급자라도 구매자가 지식 전달에 부정적인 자세를 가질 경우 신제품 개발성과에 부정적 영향을 미칠 수 있음을 시사한다.

Supply chain management(SCM) helps firms in integrating their business by collaborating with other value chain partners to meet the unpredictable demand of the end user. Agility is the fundamental characteristic of a supply chain needed for survival in turbulent and volatile markets, which are becoming norms as product life cycles shorten and environmental forces create additional uncertainty resulting in higher risk in the supply chain management. Literature reviews reveals various factors that could affect the agility. The objective of this study is to derive interdependence, partnership, quality of information, joint problem solving, modelize the mutual influential relationship between them, and look into the influential relationship influencing the agility. To test the proposed model, we used a data set generated from survey. Date analysis was conducted using 122 respondents. We used structural equation model (SEM) implemented in partial least square(PLS). The results of this study can be summarized as follows. Interdependence had a significant impact on partnership. Partnership had a significant impact on quality of information and joint problem solving. Quality of information had a significant impact on joint problem solving. Quality of information and joint problem solving had a significant impact on agility. This study diagnoses that Inter-organizational relationship characteristics are important for supply chain agility. Inter-organizational relationship characteristics are considered as an essential factor for supply chain agility.

Recently, Information systems (IS) outsourcing has been becoming a viable strategic alternative in the management of information systems. Accordingly, the demand of research in practice has been changed from how to decide IS outsourcing to how to manage IS outsourcing. However, there is little known about the management of IS outsourcing in existing literature. Moreover, the existing studies suggest conflicting solutions in accordance with their own perspectives : competitive relationship vs. cooperative relationship. The purpose of this study is to address this conflicting result, and consequently to enhance an understanding of IS outsourcing management by introducing the concept of interorganizational control. To meet this purpose, this study adopts Lee(2003)'s integrative model of IS outsourcing management based on the existing literature from different management disciplines and different perspectives, and then conducts four case studies. The result reveals that users, as well as IS manager, play a critical role in controlling IS outsourcing. Moreover, they implement a portfolio of control modes including both informal and formal modes. The result also suggests that the choice of particular control mechanism depends on client, supplier, task, and relationship characteristics.

In spite of the increase of the necessity and the interest regarding the SCM in practical business, it is difficult to judge the whole situation of the SCM because the research remain fragmentary as compared with the huge and complicated concept of the SCM. So this study defines dimension of SCM practice and measurements of SCM performance. Through an extensive literature review, the study Identifies seven dimension of SCM practice(partnership, usage of IT tools, information sharing and information quality), five measurements of SCM performance(supply chain flexibility, supply chain integration, customer responsiveness, supplier performance, and partner relationship). Five hypotheses were formulated for the relationship between SCM practice and SCM performance. The important relationships to be tested include ; (1) the direct impact of usage of IT tools on the partnership (2) the direct impact of partnership on the information sharing and information quality (3) the direct impact of SCM practice on the performance of SCM, (4) A moderating effect of top management support on the relationship between SCM practice and SCM performance.

For many years, many academics and practitioners have paid attention to the increasing popularity of corporate social responsibility (CSR) and its relationship with financial performance. They have shown that creating social and sustainable responsibility can strengthen the organization's financial performance as the organization can achieve its current needs without compromising the ability to meet future needs. While much theoretical and empirical evidence has been provided to support this argument in developed countries, this topic is under-researched, and the outcomes are controversial in developing countries. Therefore, this paper aims to examine and investigate the relationship between corporate social responsibility and financial performance in Vietnamese organizations. The dataset includes 27 firms listed on the stock market exchanges in Ho Chi Minh city (HOSE) and Hanoi (HNX) from 2015 to 2019. The disclosure approach is adopted to measure corporate social activities; four areas were developed: environment, community, employee and product, customer, and supplier practices. Return on average equity (ROE) and return on average assets (ROA) are two proxies for measuring financial performance. The research results confirm the existing literature with a strong correlation between employees and returns on average assets.

现有的文献广泛的关注财阀以及他们的所有权和支配权的优点和弱点, 但是几乎没有关于韩国非财阀公司的研究. 然而, Lee, Lee and Pennings (2001)并没有特别的探讨在韩国国内市场非财阀公司为求生存而对抗财阀公司的具有竞争力的战略. 本文的研究动机是通过四个探索性案例的研究, 韩国非财阀公司对抗财阀公司的成功的竞争战略和提出的建议可能会对其他的企业以及公共政策制定者有所帮助. 从产品相似性和公司内的合作关系分别定义竞争和合作的概念. 从这两个方面, 我们开发了以下$2{\times}2$ 矩阵, 为非财阀公司对抗财阀公司提供四种竞争战略. 在小组1的非财阀公司在高端市场对财阀公司让步, 但在低端市场有 "我也是在低端市场" 的产品, 同时承认在高端市场的财阀. 在小组2, 非财阀公司以供应商或互补企业的身份成为财阀公司的合伙人. 在小组3, 非财阀企业从事与财阀直接竞争. 在小组4, 非财阀企业的目标, 以产品创新或服务填补目标市场空白点. 我们选择的4个公司分别是E‐Rae电子企业公司(共存方), Intops(供应商), Pantech(竞争对手)和Humax(小众市场成员). 通过分析这4个案例, 相互提供更丰富的洞察力战略. 基于我们的概念框架, 提出下列假设 : 假设1 : 与财阀公司有合作关系的非财阀公司比没有合作关系的公司表现得更好. 假设1a: 共存方会比竞争方表现得更好. 假设1b: 合伙方会比小众市场成员表现得更好. 假设2: 与财阀公司的产品没有相似性的公司比有相似性的公司表现得要更好. 假设2a: 合伙方比共存放表现得更好 假设2b: 小众市场成员会比竞争方表现得更好. 假设3: 小众市场成员应比共存方表现得更好. 假设4: 按绩效的降序排列依次是合作者, 小众市场成员, 共存方, 竞争方. 一组专家按照我们4组的分类把216家非财阀公司分类. 用SPSS统计软件中的简单方差分析来检验假设. 结果发现. 与财阀公司有合作关系的以及提供与财阀公司不同的产品或服务比较好. 很明确的一点是, 平均来说, 若要对抗财阀公司中获利, 其战略是成为合伙人(供应商或组成部分). 直接与财阀公司硬碰硬的竞争是要付出极高代价的战略, 而这种代价不是非财阀公司能负担得起的. 避免与财阀公司迎面竞争的战略是用不同的产品服务于利己市场, 或是服务于被财阀公司忽视掉的低端市场. 些战略是比较好的生存战略. 本文说明在财阀环境中, 韩国的中小型非财阀公司有一些方法可以生存, 尽管不是没有风险. 根据不同的竞争组合, 合作的公司可以根据产品相似性以及合作关系的维度来选择定位从而制定自己的竞争战略. 例如共存方, 竞争对手, 合伙人, 小众市场成员. 根据我们的探索性案例分析, 合伙人对非财阀公司来说可能是最好的战略, 而竞争者则是有很大风险的. 小众市场成员和共存方处于中间, 但前者比后者要好. 很多中小型企业的管理者只是用简单的, 不是合作就是竞争的观点来审视市场的领导者‐典型的就是财阀. 结果. 很多非财阀公司变成被动的合作者或被自己的竞争对手财阀所击败. 事实上, 合作和竞争并不是互相排斥的, 是可以同时被追求的. 正如本文所建议的, 非财阀公司可以根据他们的环境, 内部资源和能力灵活的选择合作和竞争.

The present study provides some extensions over a recent work in Won (2011) which investigates properties of the static newsvendor problem under a schedule involving progressive multiple discounts under the assumption that demand is given exogenously. Khouja (1995, 1996) formulated the extended versions over the classical newsvendor model with various discount policies including all-units discount and/or multiple discounts and found that the extended newsvendor models with discount schedules yield higher optimal expected profits than the classical newsvendor model with no-discounts. In this study, we establish a robust conjecture as a stronger statement than Khouja's findings with regard to the general relationship among the expected profits of newsvendor models in the sense that the conjecture holds for every order quantity as well as the optimal order quantity. The conjecture encourages the newsvendor facing quantity discounts to safely implement her own discounts policy to customer or accept quantity discounts offered by the supplier even if the optimal order quantity cannot be ordered due to additional restrictions such as budget or warehouse capacity constraints because the newsvendor models with quantity discounts always yield higher expected profit than the classic newsvendor model without quantity discounts regardless of the order quantity. Results from wide experiments with various probability distributions of demand strongly support our conjecture.

Purpose - This study was intended to find the selection attribution factors and service satisfaction determinants of third party logistics suppliers in Dongdaemun wholesale market. Research design, data, and methodology - A questionnaire survey was performed, and the retailers and wholesalers in Dongdaemun wholesale market were asked to fill in it. Company employees using third party logistics service were selected by a random sampling method. Results - It is easy for both retailers and wholesalers to use third party logistics service. The logistics companies in Dongdaemun wholesale market have paid more heed to the security of freight and the operability. That is, the freight safety and operating service are the most important factors in selecting third party logistics suppliers, and they both have a close relationship with user satisfaction. There is no relation between service level and recognition in selection factors of third party logistics suppliers. All the responsiveness, operability and informativeness of third-party logistics providers has a significant relationship with user satisfaction. Conclusions - Third party logistics service is entirely different from the existing delivery or transport service. The most market vendors' wish for third party logistics suppliers is the stability of freight and robust operating service. They also demand the responsiveness for special or emergency situation with having information strength.
