This study examines whether firms' openness to external knowledge improves their innovative performance and what factors make openness more effective in generating innovation. Using 2008 Korean Innovation Survey in manufacturing sector, this study tests whether openness improves innovative performance and how absorptive capacity, small size and use of appropriation methods to a high degree influence the effect of openness on innovation in Korean manufacturing industries. This study finds the followings: First, the effect of openness varies depending on type of innovation. Openness is more effective for incremental innovation than for radical innovation. Second, there exists complementarity between openness and the R&D intensity when innovation is incremental. When the R&D intensity level is high, the effect of openness on incremental innovation is stronger than on radical innovation. Third, openness is more effective for small firms to perform radical innovation than incremental innovation. Fourth, when a firm uses appropriation methods to a high degree, openness is not effective for incremental innovation.

The knowledge society has come to where the knowledge is the source of wealth contrary to the traditional era that labor and capital were the source of wealth. Thus, corporate is accelerating to introduce the knowledge management and to establish the knowledge management system (KMS) in order to effectively manage the knowledge that can be the source of their competitiveness. The purpose of this paper is to identify the factors which affect knowledge sharing and to prove empirically their relationships with the KMS performance. A survey was conducted and data were collected from 220 respondents of 19 organizations which have adopted KMS. Research model and related hypotheses were tested using PLS Graph 3.0. As a result of data analysis, seven hypotheses out of eleven hypotheses were supported. In particular, knowledge sharing is significantly influenced by those knowledge sharing factors such as openness, trust, training, reward system, perceived usefulness, and communication channel. Also, individual impact is significantly affected by knowledge sharing. This study is expected to provide a sound basis for understanding the importance of knowledge sharing to gain organizational as well as individual competitiveness and exploring ways to effectively share knowledge through enhancing the use of KMS in organizations.

This paper is to investigate the degree of impact of social media use on buyer's value. Buyers of innovative digital devise are classified into three groups based on adopting behaviors. This study focuses on the degree of changes in information accessability and trust, and their associations with increased value perceived in resulting quality life. The result shows the gap in information accessability has disappeared while the one in trust remained. This implies that the gap among adopters in diffusion curve, so-called the chasm notion is very likely to be lessened or disappeared due to social network openness. Also, shown are the relationship of these variables with the degree of purchase value more stable with information accessability than with trust, all in varying patterns though. It implies that information sharing through social media be accompanied with source credibility in order to be of more value not only to buyers but also to sellers especially for new interactive devices.
