Abstract

The purpose of this study is to verify the effects of information system quality on business performance (net benefit) in the Korean public informatization business and to verify whether the user has mediating role in the relationship between information system quality and net benefit. In order to prepare empirical tests, factor analyses was conducted and the validity and reliability of the variables were confirmed to be acceptable. The research hypotheses were tested by regression analyses. The mediating effects as well as the main effects were analyzed by SPSS statistical program. The results show that the higher the quality of the information system becomes, the higher the usability by the users of the system increases. Also, it was found that the users had more positive effect on the net benefit of the public informatization project. In addition, it was confirmed that there was a partial mediating effect by the users on the relationship between information system quality and the benefits. The results of the research suggests that we establish a management system to improve the business performance efficiently according to the priorities of detailed success factors from the viewpoint of the public information business, and the users who use the information system quality and system.

본 연구는 국내 공공정보화사업에서 정보시스템 품질이 사업성과(순편익)에 미치는 영향을 확인하고, 그 과정에서 사용자가 정보시스템 품질과 순편익의 관계에서 매개역할 여부를 검증하는데 목적이 있다. 설정된 연구가설을 검증하기 위한 실증분석 방법으로 설정된 변수들과 요인들에 대한 타당성 검증 및 신뢰성 분석, 상관관계에 대한 분석을 진행하였고 정보시스템 품질이 공공정보화사업 성과에 미치는 영향에 대하여는 단순 다중회귀분석, 사용자의 매개효과에 대해서는 SPSS 통계프로그램으로 매개회귀분석을 진행하였다. 분석결과 정보시스템 품질이 높을수록 사용자의 시스템 사용성이 높으며, 사용자는 공공정보화사업의 순편익에 긍정적 영향을 미치는 것으로 나타났다. 또한, 사용자는 정보시스템 품질과 순편익의 영향관계에서 부분매개효과가 있음을 확인할 수 있었다. 이러한 연구결과를 바탕으로 공공정보화사업에서 정보시스템 품질과 시스템을 사용하는 사용자, 이를 통한 순편익에 이르는 통합적인 관점에서 세부성공요인별 우선순위에 따라 효율적으로 사업성과를 향상 시킬 수 있도록 관리체계를 수립하고 공공정보화시장에 진입한다면 기업경영 성과 및 관련 산업 전반에 유의한 영향을 미칠 수 있을 것이다.
