본 연구는 구매자-공급자 간 협력에 기반을 둔 기술혁신 성과창출에서 공급자 조직 학습역량의 역할에 초점을 두고 있다. 이를 위해 본 연구는 국내 제조업에 종사하고 있는 중소기업 221개사를 이용하여 매개효과분석을 수행하였다. 실증검증 결과, 공급자의 기술혁신 성과에 대한 구매자의 직접지원(기술인력 지원, 기계도구 및 검사장비 지원, 설비사용 교육)은 통계적으로 유의하지 않았지만, 구매자의 간접지원(지식, 노하우, 가치, 정보 공유)은 긍정적이며 유의한 효과를 갖는 것으로 나타났다. 매개효과분석을 위한 추가 검증 결과, 공급자의 학습역량과 구매자의 간접지원 사이에 부분 매개효과가 존재한 반면에 구매자의 직접지원과 공급자의 학습역량 간에는 완전 매개효과가 존재하는 것으로 나타났다. 이 연구결과는 구매자의 간접지원이 공급자의 기술혁신 성과를 향상시키는데 더욱 중요한 역할을 할 수 있음을 제시한다.

Managers have come to realized that a large and increasing amount of sources for a corporate competitive advantage can be found in their company's supply chain. At a fundamental level, there is a similar consensus that building a collaborative supply management is a more effective way of managing firms' supply chains. This paper is an attempt to examine the effects of collaborative supply management by probing a mechanism which shows how competences and/or performance are transferred from suppliers to markets through the supply chains. Research hypotheses regarding the relationships between collaborative supply management, supplier Performance, buyer internal performance (new product development and operational performance), and buyer market performance were empirically validated by utilizing a structural equation modeling analysis. The research result Indicates the positive impacts of a collaborative supply chain on supply performance as well as buyer internal and market performance, which also well illustrate how the improved competence and/or performance of suppliers engendered from the supplier-buyer collaboration flows throughout the entire supply chain.

This study identified the present state of store and selection criteria of supplier from the regional fashion buyer point of view and examined the effects of the factors of relative impact between buyer and supplier on the relational bond. The interviews and questionnaires were administered to the owners or the sellers of 85 fashion retail stores in Gwangju. For analysis of data, frequency, means, factor analysis, Cronbach's ${\alpha}$ and regression analysis were applied. The results were as follows. First, in the results of examining the actual conditions of store managers for fashion buyers, fashion buyers complained about lengthy travelling and time consumption inconvenience. They also reported decrease in margin and monthly mean sales over last year. Second, the most important selection the criteria for the supplier were product power, followed by a convenient store layout. Finally, higher quality communication, more compromises, and higher dependence were affected with higher satisfaction, trust, and commitment in suppliers; conversely, the trust and commitment of the buyers decreased relative to the increased power of the suppliers.

In this paper, we analyze a logistic system involving a supplier who produces and delivers multiple types of items and a buyer who receives and sells the products to end customers. The buyer controls the inventory level by replenishing each product item up to a given order-up-to-level to cope with stochastic demand of end customers. In response to the buyer's order, the supplier produces or outsources the ordered item and delivers them at the start of each period. For the system described above, a mathematical model for a single type of item was developed from the buyer's perspective. Based on the model, an efficient method to find the cycle length and safety factor which correspond to a local minimum solution is proposed. This single product model was extended to cover a multiple item situation. From the model, algorithms to decide the base cycle length and order interval of each item were proposed. The results of the computational experiment show that the algorithms were able to determine the global optimum solution for all tested cases within a reasonable amount of time.

Discovering the suppliers capable of manufacturing the parts that satisfy buyer requirements via current online market places remains difficult due to semantic differences between what the suppliers can produce and what the buyer wants to acquire. One of the promising approaches to overcome the semantic difference is to adopt an ontology to describe the suppliers' manufacturing capabilities and the buyer requirements that range widely from manufacturing costs to eco-friendly design. Such an ontology dedicated to supplier discovery has yet to be developed. MSDL(Manufacturing Service Description Language) provides the basis for defining terms and their relationships in the ontology. Thus, the objective of this paper is to extend MSDL into a new ontology suitable for supplier discovery in mold manufacturing industry. In addition, a new ontology development method for supplier discovery will be proposed. Finally prototype demonstrations are provided to show a feasibility of the proposed ontology in mold manufacturing domains.

We explore the determinants of long-term relationship between the buyer and the supplier to help suppliers develope a strategy to build long-term relationship with their buyers. Based upon an extensive literature review, we propose three droops of independent variables which may affect long-term relationship, including (a) environmental factors (product complexity, product importance, source dependence, price sensitivity), (b) relational factors(trust, commitment, satisfaction, intention of expansion), (c) operational performance(quality, delivery, cost capability, technical knowhow). The buyer's actual period of relationship with its main supplier is used as a dependent variable. Using hierarchical multiple regression analysis, we empirically test hypotheses, analysing a sample of 290 manufacturing firms in the U.S. The statistical results indicate that the buyer's source dependence, price sensitivity and the supplier's commitment play a significant role in establishing long-term relationship between the buyer and the supplier. However, the supplier's cost capability and technical knowhow in operational performance negatively affect long-term relationship in contrast with our hypotheses. Due to this controversial result, we divide the sample group Into dual sourcing and multiple sourcing environments and reconduct regression analysis in a post hoc manner. The findings show that the supplier's cost capability and technical knowhow are negatively associated with the length of relationship only in the multiple sourcing environment. The results may confirm that both parties' opportunistic behavior is more salient in the multiple sourcing environment than in the single sourcing environment.

The purpose of this research is to investigate success factors for supply chain management. According to the statistical analysis of 98 survey data, we find that the success factors mentioned in this literature(Supplier-Buyer relations, Inter-organizational Coordination, Planning & Control, Information Technology) positively affect the corporate performance. This research also indicates that supply chain management should be implemented according to dependent industrial characteristics and external conditions. We used three key environmental factors: (1) The product exchanged and its technology, (2) the competitive condition in downstream market, (3) capabilities of the suppliers available.

In this paper, we consider an integrated inventory system where a single supplier purchases and processes raw materials in order to deliver finished goods to a single buyer for effective implementation of Just-In-Time purchasing. An integrated JIT lot-splitting model of facilitating multiple shipments in small lots is developed in a JIT purchasing environment. Also, an iterative solution procedure is developed to find the order quantity for the finished goods and raw materials, and the number of shipments between buyer and supplier. We show by example that the integrated policy adopted by both buyer and supplier in a cooperative manner can provide them a greater economic benefit than seeking the local optimal inventory policy independently.

Purpose - This study aims to investigate whether the buyer's participation in CSR activities can affect the informal cooperation and relationship beyond formal cooperation and relationship. Research design, data, and methodology - We defined the research model and selected variables(monitoring and contracts by the buyer, formal cooperation & relationship, and informal cooperation & relationship). After completing the questionnaire, we analyzed 319 manufacturing companies. Prior to the hypothesis testing, Exploratory factor analysis(EFA) and confirmatory factor analysis(CFA) were conducted to check for discriminant validity and convergent validity. Results - The stronger the buyer monitoring on the company's CSR activities, the more positive it affects the formal business cooperation. On the other hand, strong buyer monitoring did not affect formal business relationships. Therefore, even if buyers' monitoring of CSR activities is strong, it does not mean that the formal business relationship is improved, but it means that it is possible to improve the formal business cooperation. Conclusions - This study shows that the stronger the buyer monitoring on the supplier's CSR activities, the more positive it affects formal cooperation. It also demonstrates that formal business cooperation between the supplier and the buyer, that is, sharing goals and works for CSR activities, has a positive effect on relationships based on emotional exchange and commitment.
