With the recent spread of COVID-19, the size of the online shopping market continues to increase, and various online platforms are appearing in the market, and many small and medium businesses are entering the platform. As the recent increase in the use of the platform by small andmedium businesses as raised the issue of appropriate platform fees, the need for social discussions on the use of the platform and fees is raised. Currently, most discussions regarding fees primarily focus on specific cases from a negative perspective, and discussions that comprehensively consider the platform's utilization value and fees are insufficient. Therefore, this study aims to systematically and comprehensively understand platform fees by considering the value of using platform services and commission costs together. To achieve this, the economic value of each platform service was estimated and analyzed in detail. It selected two industries that are actively using online platforms, delivery services and e-commerce, and paid attention to changes in expected profits generated by sellers using platform services, and compared and analyzed expected profits based on estimated sales and costs for each scenario, such as whether sellers entered the platform and whether they used the service. As a result of the study, our results that entering the platform and using the platform service enable sales increase and cost reduction, which have a positive effect on the seller's expected profit. Through this study, we intend to understand platform fees from the perspective of user fees for platform service use and value acquisition, and based on this, estimate the economic value of platform services and fees to expand the value and cost of using platform services to a comprehensive and systematic discussion.

This study investigates intents of acquisitions in information technology industries. Mergers and acquisitions are a strategic decision at corporate-level and have been an important tool for a firm to grow. Plenty of firms in information technology industries have acquired startups to increase production efficiency, expand customer base, or improve quality over the last decades. For example, Google has made about 200 acquisitions since 2001, Cisco has acquired about 210 firms since 1993, Oracle has made about 125 acquisitions since 1994, and Microsoft has acquired about 200 firms since 1987. Although there have been many existing papers that theoretically study intents or motivations of acquisitions, there are limited papers that empirically investigate them mainly because it is challenging to measure and quantify intents of M&As. This study examines the intent of acquisitions by measuring specific intents for M&A transactions. Using our measures of acquisition intents, we compare the intents by four acquisition types: (1) the acquisition where a hardware firm acquires a hardware firm, (2) the acquisition where a hardware firm acquires a software/IT service firm, (3) the acquisition where a software/IT service firm acquires a hardware firm, and (4) the acquisition where a software /IT service firm acquires a software/IT service firm. We presume that there are difference in reasons why a hardware firm acquires another hardware firm, why a hardware firm acquires a software firm, why a software/IT service firm acquires a hardware firm, and why a software/IT service firm acquires another software/IT service firm. Using data of the M&As in US IT industries, we identified major intents of the M&As. The acquisition intents are identified based on the press release of M&A announcements and measured with four categories. First, an acquirer may have intents of cost saving in operations by sharing common resources between the acquirer and the target. The cost saving can accrue from economies of scope and scale. Second, an acquirer may have intents of product enhancement/development. Knowledge and skills transferred from the target may enable the acquirer to enhance the product quality or to expand product lines. Third, an acquirer may have intents of gain additional customer base to expand the market, to penetrate the market, or to enter a foreign market. Fourth, a firm may acquire a target with intents of expanding customer channels. By complementing existing channel to the customer, the firm can increase its revenue. Our results show that acquirers have had intents of cost saving more in acquisitions between hardware companies than in acquisitions between software companies. Hardware firms are more likely to acquire with intents of product enhancement or development than software firms. Overall, the intent of product enhancement/development is the most frequent intent in all of the four acquisition types, and the intent of customer base expansion is the second. We also analyze our data with the classification of production-side intents and customer-side intents, which is based on activities of the value chain of a firm. Intents of cost saving operations and those of product enhancement/development can be viewed as production-side intents and intents of customer base expansion and those of expanding customer channels can be viewed as customer-side intents. Our analysis shows that the ratio between the number of customer-side intents and that of production-side intents is higher in acquisitions where a software firm is an acquirer than in the acquisitions where a hardware firm is an acquirer. This study can contribute to IS literature. First, this study provides insights in understanding M&As in IT industries by answering for question of why an IT firm intends to another IT firm. Second, this study also provides distribution of acquisition intents for acquisition types.

With rapid economic development in China, cargoes from and to China are growing significantly. The 3 Northeast Provinces of China(named Liaoniang, Jilin, Heilongjiang provinces), bordering the Korean Peninsular, is not exception in development of international trade. However long distance from the 3 Northeast Provinces to seaports generates huge transit time and costs because Dalian port is far away almost 1,000km from Jilin and Heiloongjiang Provinces. The new intermodal transport route through the port of Jarubino located in the Russian Far East is under way to reduce the costs incurred from inland transport. This paper investigates the competitiveness of the new international intermodal transport route from the 3 Northeast Provinces in terms of transit time and transport costs. According to the results of this research, The establishment of the new international intermodal transport with development of Jarubino port is expected to increase the competitiveness of trade cargoes from the 3 Northeast Provinces while Korea has a good opportunity to join the port development in the Russian Far East. Futhermore the port of Busan is also benefited the growing transit cargoes from the new intermodal transport route.

Roadmap of cyber trade offers members the opportunity to interact electronically with like-mined individuals and to both create and buyer relevant to a topic of interest. Roadmap of cyber trade was conduct on the economic effect of electronic commerce according to the method of constructing the Internet. Firms using cyber trade have difficulty enjoying a uniformly identical effect. That is, since the improvement effect of the intrafirm business method, unnecessary repeated manual paperwork and the use effect of being able to maintain the close relationship with to the parties to trades in the process of prompt receipt and delivery of documents are long-term and indirect effects, they have some limitation in that they can not be measured as coefficients but only as scales. In terms of business management, the intensification of corporate competitiveness improved by $10.00\%$ in case of less than 10 times and by $11.53\%$ in case of 50 to less than 50 times. And it was found that the effect of profit increase as the number of inquiries was large. That is, it was found that the effect of profit increase was $10.88\%$ when the number of inquiries was less than 10 times but it increased to $14.00\%$ in case of 50$\∼$less than 100 times. Therefore, to revitalize cyber trade, it is thought that government, the academic community and the business world all need to make much research into and sustained investment in cyber trade.

Using survey data and the Heckit model that adequately controls the sample selection bias, we analyze shoppers expenditure through two major emerging shopping channels: Internet shopping and TV home shopping channels. Age, Internet experience, daily Internet usage, the number of computers are factors that affect the ratio of consumers' expenditure through Internet shopping relative to the expenditure through TV home shopping. Shopping frequency which represents the shoppers' incentives to reduce transaction costs also has a positive effect on the proportion of shoppers' expenditure through the Internet shopping. Shoppers' perceptions of convenience, reliability, speed, and diversity are also shown to affect shoppers' relative expenditure ratio through Internet shopping. In contrast, shoppers' perception of prices does not seem to affect their purchasing behavior.

전력거래소는 발전경쟁시장(CBP; Cost-Based Pool) 장기화에 따른 운영상의 효율성을 개선하고 기 개발된 시장운영시스템(MOS; Market Operation System)을 활용하여 급전체계를 개선하기 위해 준비중이다. 현행 급전체계에서는 거래 전일에 수행한 수요예측을 바탕으로 1시간 단위운영발전계획을 전일에 수립하고 EMS(Energy Management System)를 이용하여 발전기에 대한 경제부하배분(ED; Economic Dispatch)을 시행하고 있지만, 현 EMS는 시장체제 환경 전에 도입된 설비로 시장환경에 대한 고려가 되어 있지 않고 계통운영 보조서비스의 실시간 반영이 어려운 점이 있다. 전력거래소는 실시간 급전 운영을 위해 기존 EMS에 MOS를 연계하여 MOS의 5분 단위 수요예측량을 기반으로 송전망 제약과 예비력 요구량 등을 고려한 발전기별 경제부하 배분량 및 예비력 배분량을 결정하고, 추가적으로 EMS에서 수요예측 오차 및 주파수 보정량을 실시간으로 계산하여 발전기별로 배분하도록 함으로써, 1일 전 시행하던 급전계획을 취득 자료를 기반으로 5분 단위로 실시간 계산할 수 있도록 급전 체계를 개선할 계획이다. 이를 통해 실시간으로 에너지와 예비력을 동시에 최적화함으로 전력시장 및 전력계통 운영을 한층 선진화 할 수 있는 계기를 마련하였으며 또한 저비용 발전기 사용을 극대화함으로 발전비용의 절감에도 기여하는 효과를 기대할 수 있다. MOS-EMS간 자료연계에는 ICCP(Inter-Control Communication Protocol)와 FTP 프로토콜을 사용하였고, 수차례 모의운영을 통하여 데이터베이스 및 현장 취득 자료의 정확도(accuracy)가 양 시스템 간 연계 및 전력 계통의 안정적 운영에 매우 중요한 요소로 나타났다. 전력거래소는 장기적으로 CIM(Common Information Model)기반의 표준 전력계통 데이터베이스를 구축하고 시스템 간 자료 연계를 위해 XML을 활용하여 시스템 간 상호 운영성(Interoperability)과 자료 연계의 안정성을 높일 계획이다. 본 논문은 MOS-EMS 연계에 따른 시스템 간 자료의 흐름 및 처리에 대해 주로 설명하고자 한다.

This paper analyzes retailers' purchasing patterns of fruits and vegetables and the problems with purchasing from agricultural product wholesale markets. While large-scale retailers purchase fruits and vegetables from various sources, medium and small-scale retailers and food service companies buy them mostly from agricultural product wholesale markets. The retailers point out the problems with purchasing from agricultural product wholesale markets as a lack of quality uniformity, not sufficient cooling storage facilities, not sufficient space for shipping area, high distribution cost, unnecessary price fluctuation, and etc. In order to enhance the linkage with retailers, agricultural product wholesale markets, first of all, have to adopt more flexible trading methods such as private treaty besides auctions which are exclusively legitimate trading methods in the market. Necessary are enlargement of jobbers' operating scale, securing shipping space for retailers, adoption of inspection service, introduction of methods to stabilize auction prices, saving of loading and unloading costs, implementation of marketing strategies.
