In collaborative product development with multiple suppliers, buyers must manage the suppliers' activities. This empirical research investigates the performance impacts of three strategies that buyers use to manage suppliers who design interdependent components. These strategies are: Instructionism (giving clear instructions to suppliers), Teaming (forming an interactive development team with suppliers), and Delegation (transferring component development responsibilities to suppliers). Data were collected through a cross-industry web-based survey of buying firms in manufacturing industries whose products require multiple, interdependent components. A path analysis utilizing 318 survey responses indicates that Instructionism has a positive effect on design quality, and Teaming has a positive effect on design quality and component innovation. The use of Delegation is not related to any of the performance indicators. The practical implication of this research for product development managers is that both Instructionism and Teaming can be effective strategies. For the purpose of assuring design quality, a buyer should give clear instructions in detailed specifications or work closely with suppliers in development teams. If competitive priority is product innovativeness, however, the buyer should work closely with its suppliers during component development processes using a Teaming strategy.

This paper proposes 2 problems of Internet Marketing. Firstly, nowadays many people are aware of Web Service and the services that are available in cyberspace. However they are not fully aware of the concepts and range of Web Services. Secondly, most of the research of Internet Marketing focuses on the service quality of cyber shopping using SERVQUAL in relationship to service quality of shopping malls. Therefore they have a lot of limitations because they do not understand all the media characteristics of Internet. Basically the Internet has service parts and also has characteristics of new advertising. But many research papers do not consider these respects. The purpose of this paper is to study of the effects of Web Service Quality on Internet Commerce Transactions. To accomplish the purpose of this paper effectively, theoretical background of web services was reviewed briefly. We defined Web Services and categorized them. We found that the components of Web Service Quality are Information Providing Service Quality and Advertising Service Quality. Factor analysis is conducted according to the dimensions of each component. We conducted Path analysis how these components affect buyers'attitude and buyers'attitude affect revisit intentions and buyer intentions. The results show that strategies of cycler brand construction are better than strategies of selling to web surfers. The strategies of cyber brand construction are related to buying in that customers increase their visits to the entrepreneur's Web site and this increases the loyalty to that site therefore this is related to buying habits.

Purpose The purpose of this study is to identify the related factors of cautious purchasing for buyers who have purchased products in online shopping mall. First, we focus on the prevention focus, which is one of the personal characteristics, that affect the cautious purchase, and analyze the satisfaction of purchasing according to cautious purchase. Furthermore, we investigate the influence of emotional intelligence (self-awareness and social-awareness) on the process of cautious purchasing and satisfaction. Design/methodology/approach In order to verify the hypotheses, this study surveyed individuals who purchase products on the Internet for about 2 months from August to September 2016. A total of 250 copies were returned, but 20 questionnaires that were incomplete were excluded. Thus, the final 230 samples were analyzed. Structural equation modeling (SEM) was used for hypothesis testing. Findings The result of this study showed that the cautious purchasing is stronger for the buyers with the prevention focus. And consumers who purchase carefully have higher satisfaction after purchasing. In addition, emotional intelligence in the cautious purchasing process has a positive moderating effect. Based on the results of this study, the theoretical and practical implications are suggested.

In this study, the effect of innovativeness of external networks on the corporate innovativeness and innovation performance were explored based on web survey data collected from 230 manufacturing companies. Specifically, according to the manufacturers' business categories divided by the technology level, three groups such as advance technology (electronic/IT), mid- to high technology (automobile/machine), and low technology (textile/clothing) companies were investigated to find out which external network influences corporate innovativeness and innovation performance. In the result, textile/clothing companies were not different in company size, history, and innovation effort from advanced technology and mid- to high technology companies. Collectively, the innovativeness of external networks affected corporate innovativeness and innovation performance. In the result by a business category, innovativeness and innovation performance of textile/clothing companies were affected by the innovativeness of competitors, whereas automobile/machine companies in the mid- to high technology group were affected by suppliers. In addition, advanced technology (electronics/IT) were affected by buyers and competitors. These differences suggest that the way to use vertical networks toward upstream (e.g., suppliers) and downstream (e. g., buyers) as well as horizontal networks toward competitors can be different by the business category of manufacturers. The result would provide implications for the academia and the industry.

Even though much research has been performed to recommend favorite items to the buyers in the internet shopping mall, to the best of our knowledge. it is hard to find previous research on the recommendation of buy points. In this paper, we propose a method which can be used to recommend buy points of an item to the buyers. To do this, a database containing normalized price patterns is constructed from the archive of past prices. Then, the future price pattern is retrieved from the database based on the similarity. Here, regression analysis is used to find and analyze the elements that affect the price. We also present performance results showing that the proposed method can be useful for shopping malls.

More and more cyber shopping malls, one of the new promising Internet businesses of today, are opening business everyday. And instead of the ordinary image and text type of product display, buyers can now view products from any viewpoint through 3D images and also get more detail information on the product more easily thanks to the new VP technology, visual tools, and statecharts. However the currently used virtual prototyping supporting method does not consist of any database support for sharing the data from different virtual prototype developments and reusing the data in developing other prototypes. And in cases of custom order products, there is no linkage with the virtual product database that enables buyers in cyberspace such as cybermalls to try out the products before purchasing. This paper is purported for being applied as the basis for planning the construction of a complete CRM method applied cyber shopping mall that can accommodata all the demands and requests from customers. And the database supporting VP framework that supports data sharing and collaboration between virtual prototype developers and manufacturing custom order products is suggested for this purpose.

This research describes the comparison broker's role and its effectiveness measurement using a developed logical framework of comparison shopping service. And verifies that seller-led comparison challenge method provide comparison information of products to buyers more efficiently. In electronic commerce, buyer's satisfaction of purchase (S) can be defined as an interactive function between seller's competitiveness vector (P) of products that supplied to the market, and buyer's informed level vector (B) of products that is known from a lot of sources. Then the buyer's informed level can be changed through the information analysis among products by transformation process using comparison matrix (C). So the role of comparison shopping is to construct a comparison matrix and to serve it to the buyers, and to change the buyer's informed level. The changed informed level influences a buyer's satisfaction, that improved satisfaction of purchase is defined as the effectiveness of comparison shopping. As a perfect provision and usage of comparison matrix is impossible cause of cognitive limit, the most efficient method for improving the comparison effectiveness is the comparison challenge that detects the comparison elements of the largest buyer's information efficiency, and then to be compared between elementary products selectively. This research verifies the substantial superiority of comparison challenge through television market data experiments.

The purpose of this study was to investigate the influential variables of impulse buying for jewelry. A survey questionnaire was developed from previous researches. Data were obtained from female consumers who have purchased jewelry products living in Busan. The results showed that impulse buying of jewelry was influenced by shopping orientation, consumption value, store attributes, store types, and demographic variables. The impulse-buyers of jewelry were more likely to be recreational and fashion-oriented shoppers and to have store/brand loyalty than unimpulse-buyers. Additionally, they perceived importantly the uniqueness, newness or fashionability of jewelry, kindness of salesperson, store atmosphere, various design and assortment, and special sales of the jewelry store. They were more likely to patronize the department store and franchise store to purchase jewelry products. They also tended to spend more for jewelry and more frequently visit the jewelry store. Findings should provide the informations to assist marketers and researchers in their understandings of the jewelry market.

In deriving the economic order quantity (EOQ) formula, it is tacitly assumed that the buyer has to pay product price while receiving the product from the supplier. However, as a marketing policy, some suppliers permit a delay in payments to the buyers to increase demand for the product they made. Credit transactions would have a positive effect on both suppliers and buyers. For a supplier who offers trade credit, it is an effective means of price differentiation to increase the demand for the product. Availability of opportunity to delay the payment in buyer effectively reduces the cost of holding stocks and therefore, the buyer has a lot of price options to choose his sales price for a customer. Since the buyer's order is affected by the customer's demand, the problems of determining the sales price and EOQ are interdependent and must be solved simultaneously. From this perspective, this paper evaluates the problem of determining the optimal sales price and EOQ for the buyer at the same time when the supplier allows a delay in payments for the product whose demand is represented as a function that decreases linearly with the sales price. For the analysis, it is also assumed that inventory is exhausted not only by customer's but also by decay.
