Sharing Economy is the modern main item with ICT Development. Of course sharing economic item is the old and long run mainstream, but by the ICT technological development sharing economy is the fostering and affluent factors in the world economic growth. Though, in Korea, till now sharing economy is minimal, that will growth sharply. We can track various business models of sharing economy. Sharing economy is to buy use right not ownership. With the sharing economic business model wee can make also financial sharing model. In finance model we can divide two kind models. First, we can trace small size lending model with p2p type. And second, we can make financial information transaction model. But till now sharing economic system is not activated, because of many reasons. To activate, first we have to set law and various standards, and also government actively support many sharing economy firms and institutions. To catch up developed countries in the field of sharing economy we have to make aggressive and flexible rules and standards.

This paper examines the effects of environmental uncertainty, structural decentralization, formalization, complexity and task interdependence on the information sharing through information system. 197 firms in Korea are surveyed and analyzed to investigate the relationship between the contextual variables and the information sharing. The result of multiple regression analysis shows that task interdependence, structural decentralization, complexity are significant factors to influence on the Information Sharing. Also, additional analysis shows that task interdependence, structural decentralization are major factors in service industry, and task interdependence, structural complexity are in manufacturing industry.

The sharing economy has significantly changed the way of living for years. The emergence and expansion of sharing economy empowered by the mobile information technologies and intellectual algorithms reconfigure how people use transportation means. In this paper, the bike sharing phenomenon is highlighted. Combining a big data set provided by the Seoul government about user logs and air quality data set, the empirical findings reveal that temperature change is tightly associated bike sharing activities. Also, the concentration of particulate matter is weakly related to bike sharing, but the trend should be carefully examined. By considering external environmental factors to bike sharing businesses, this work is differentiated. To further understand empirical data, data mining methods and econometric approaches were adopted.

The purpose of this study is to investigate the relationship between knowledge sharing and academic performance in the context of quality-assurance related work. It furthermore aims to explore the role of information technology in mediating this relationship. Quantitative method was applied to collect data from the participants using an online-based questionnaire. Convenience sampling technique was used. The responses were collected from 140 participants in a university from Saudi Arabia. The study found a strong positive relationship between knowledge sharing and individual performance. It was also found out that information technology partially mediates the relationship between knowledge sharing and individual performance. The research unearths the significant contribution made by information technology in mediating the relationship between individual-level knowledge sharing and the individual performance. This helps to understand the positive impacts on individual work performance in institutions of higher education that would be derived if individuals use various forms of IT to share knowledge. The focus of the research is the individual performance as the pertinent contribution towards positive outcomes in institutional performance.

Purpose Virtual communities change the way people communicate and share information. The purpose of this paper is to find how internet social capital and individual motivations influence the information sharing in virtual communities. This study considers the social capital theory, individual motivations, information sharing, and community promotion to construct a theoretical model. Design/methodology/approach Social capital focuses on three dimensions that include 6 factors: social interaction ties, centrality, shared language, shared vision, trust and reciprocity. Individual motivations include 2 factors: reputation and enjoy helping. To confirm the research model and the hypotheses, 426 effective questionnaires were used for the final analysis. Findings The result of data analysis demonstrates that social interaction ties, centrality, shared language, trust, and reciprocity were significant in affecting information sharing behaviors. However, reputation, enjoy helping, and shared vision does not appear to have a significant influence on information sharing behaviors. The information sharing was positively related to community promotion.

오늘날 정보공유는 점차 지능화, 고도화되어 나타나고 있는 사이버공격을 효과적으로 예방할 수 있는 수단으로 인식되어 미국, EU, 영국, 일본 등 전세계적으로 국가적 차원의 사이버 위협정보 공유체계를 구축하고 있다. 특히 미국은 지난 2015년 12월 "사이버위협정보공유법(CISA)"을 제정하는 등 오래전부터 위협정보 공유를 위한 법 제도 기반 마련, 수행체계 구축 이행을 추진해오고 있다. 우리나라는 국가사이버안전센터와 한국인터넷진흥원을 중심으로 각각 공공, 민간분야에서 사이버 위협정보를 수집, 공유하고 있으며 관련 법 제도의 도입 시행을 통한 일원화된 정보공유 절차의 마련과 수행체계 구축을 추진 중에 있으나, 사이버 위협정보 공유 과정에서 발생할 수 있는 기업 또는 개인의 민감정보 유출문제, 정보수집 관리 주체에 대한 신뢰, 효용성 등의 문제의 우려도 제기되고 있는 실정이다. 본 논문에서는 미국과 우리나라의 사이버 위협정보 공유 현황의 비교 분석을 통해 향후 우리나라의 성공적인 사이버 위협정보 공유 체계정착이 이루어지는데 필요한 요구사항 및 시사점을 도출해보고자 한다.

The purpose of this study is to identify the impact of IT group efficacy of small business using B2B e-commerce on organizational performance. First, we conceptualized IT group efficacy, based on theories in regard to group efficacy, absorptive capacity, and electronic information sharing. And then we examine that IT group efficacy of small business setting up IS and performing B2B e-commerce increases absorptive capacity and electronic information sharing, and ultimately improves organizational performance. The result is that IT group efficacy has a significant positive effect on absorptive capacity, but doesn't have a significant positive effect on electronic information sharing. Also absorptive capacity has a significant positive effect on electronic information sharing and organizational performance, and electronic information sharing has a significant positive effect on organizational performance. Finally, we discuss about the limits and directions as well as the results and implications of this study.

Information sharing is key to effective supply chain management. In reality, however, it is impossible to get perfect information. Accordingly, only uncertain information can be accessed in business environment, and thus it is important to deal with the uncertainties of information in managing supply chains. This study adopts meteorological forecast as a typical uncertain information. The meteorological events may affect the demands for various weather-sensitive goods, such as beer, ices, clothes, electricity etc. In this study, a beer distribution game is modified by introducing meterological forecast information provided in a probabilistic format. The behavior patterns of the modified beer supply chains are investigated. for two conditions using the weather forecast with or without an information sharing. A value score is introduced to generalize the well-known performance measures employed in the study of supply chains, i.e.. inventory, backlog, and deviation of orders. The simulation result showed that meterological forecast information used in an information sharing environment was more effective than without information sharing, which emphasizes the synergy of uncertain information added to the information sharing environment.

In this paper, the impact of information sharing, possibly with some delay, on costs in a simple supply chain in which there are two participants, a single retailer and a single manufacturer, is considered. When participants in the supply chain do not use fully integrated EDI, some delay associated with information sharing is inevitable. A mathematical model that allows us to quantify the cost incurred by the manufacturer in the supply chain under information sharing, possibly with some delay, vs. no information sharing is presented. From this model, some managerial implications are gleaned.
