This paper provides an empirical evidence that the entry of a technology supplier depends on the markets for technology. In particular, using the chemical industry dataset, we test the hypothesis that the number of specialized engineering firms (SEFs) depends on the number of licensors in the market. Moreover, the number of plant investment, which is a market demand shifter is positively related with the entry of the SEFs, while the effect of the GDP pre capita does not have a significant effect on the entry of the SEFs.

This study compares and analyzes wholesale(or price-only) contract, revenue-sharing contract, quantity-flexibility contract, and channel-rebate contract in a decentralized supply chain consisting of one supplier and one retailer. By setting the parameters of each coordination contract based on the previous results, we conduct simulations using @RISK for several combinations of these parameters. Under the supply chain coordination, we evaluate the probability of successfully signing a contract and the participant in favor of each contract. As a result, the quantity-flexibility contracts is most advantageous for the retailer and the channel-rebate contracts is most advantageous for the supplier. It revealed that revenue-sharing contracts can be used more flexibly because they can be selected in the widest range to redistribute profits between supplier and retailer.

In this study, we intended to find out how to improve the relationship performance between a hospital who is a buyer and its suppliers in the medical supply chain. For specific, in control of the transaction period and the number of bed, we investigated the effect of information sharing between a buyer and its suppliers along with the trust for the suppliers' capabilities perceived by the buyer on the buyer's relationship performance. In addition, in control of the transaction period and the number of bed, we also examined the influences of moderating effect of the interactional justice on the relations between information sharing and relationship performance, and between capability-trust and relationship performance. For this, we conducted reliability analysis, exploratory/confirmatory factor analyses, discriminant validity analysis, and moderated multiple regression analysis including control variables. Our results showed that there are positive effects of information sharing between a buyer and suppliers, and the buyer's perceived trust for the suppliers' capability on the relationship performance while controlling the transaction period and the number of bed. Besides, we empirically confirmed that there was the moderating effect of the interactional justice on the relations between capability-trust and relationship performance, whereas we could not find that statistically significant moderating effect of the interactional justice on the relations between information sharing and relationship performance.

Brands are important in the consumer market. They are the interface between consumers and the company, consumers may develop loyalty to brands. also, The late development of industrial marketing explains the near absence of research on Brand Equity in business to business. With recent change, industrial companies have shifted from a production focus to a customer focus. industrial brand is fast developing. The basic purpose of this study is to investigate industrial brand trust and loyalty affecting the Result of business relationship between industrial buyers and suppliers. Factors hypothesized to influence trust in a brand include a number of brand characteristics, company characteristics and consumer-brand characteristics. This research presented a comprehensive constructive model consisting of components of industrial brand trust and loyalty, and then propose the research model base on prior researches and studies about relationships among components of industrial brand loyalty. Data were gathered from respondents who work in industrial buying center. For this study, Data were analyzed by SPSS 10.0 and AMOS 4.0. The results of this research analysis were as fallow. Industrial brand trust and loyalty were positively related with a number of industrial brand characteristics, supplier characteristics and buyer-brand characteristics. relationship commitment. This research newly proposed the concept of 'industrial brand trust and loyalty affecting the Result of business relationship between industrial buyers and suppliers'

Given the recent trend in business markets to seek and conscientiously develop long-term relationships, it has become increasingly important to understand why such long-term relationships are developed and how they are maintained. Despite their obvious importance, the antecedent conditions and processes of long-term relationships between industrial buyers and suppliers have not been systematically studied. In this research, I report a study of the antecedents of industrial buyer-seller relationships and the relational performance. What kinds of factors contribute to the development of long-term relationships\ulcorner How do these factors influence the corporate performance in the business markets\ulcorner The primary motivation of this study was drawn from an interest in answering these research questions. Managerial implications of the study results are also discussed.

With the emergence of indirect procurement, it has become a global trend for companies to outsource their maintenance, repair, and operating (MRO) supplies to procurement service providers (PSPs). Due to the variety of MRO items, evaluation of numerous suppliers in various industries is a particularly complex task for PSPs. Due to this complexity, many PSPs still evaluate and select suppliers based on the sourcing managers' subjective knowledge. Through the case of adopting a supplier evaluation system, this research is to find the managerial issues organizations should consider when they transform sourcing managers' knowledge into the system. We interpret the issues based on the Technology-Organization-Environment (TOE) framework. This case conclusively shows the importance of positive feedback loop between the users and the information system for the performance improvement of the system.

This research is an application of game theory to developing the supplier selection and demand allocation mechanism, which are the essential and major research areas of supply chain planning and operation. In this research, the most popular and widely accepted mechanism, the progressive reverse auction is analyzed and compared with the other game theoretic approach, Kalai-Smorodinsky Bargaining Solution in the viewpoint of holistic efficiency of supply chain operation. To logically and exquisitely compare the efficiencies, a heuristic algorithm based on Genetic Algorithm is devised to find the other optimal demand allocation plan. A well known metric, profit-cost ratio, as well as profit functions for both suppliers and buyer has been designed for evaluating the overall profitability of supply chain. The experimental results with synthesis data and supply chain model which were made to mimic practical supply chain are illustrated and analyzed to show how the proposed approach can enhance the profitability of supply chain planning. Based on the result, it can be said that the proposed mechanism using bargainging solution mayguarantee the better profitability for the whole supply chin including both suppliers and buyer, even though quite small portion of buyer's profitability should be sacrified.
