本論文主要目的在於利用資源基礎理論探討PACS與放射部門績效之關聯，並找出醫院中能夠提升PACS績效的資源。本論文採用問卷調查法，主要研究對象為國內18家採用PACS的醫學中心之放射科醫師，共計發出210份問卷，回收64份有效問卷。研究結果顯示醫院內部資源包括「人力資源」及「流程資源」與「PACS績效」呈現顯著相關，然「PACS資源」與「PACS績效」並無顯著關係，而「PACS績效」的確與「放射科績效」顯著相關。針對調查分析結果，本論文進行事後訪談並提出其他潛在與PACS績效相關之因素。本論文建議醫院管理階層應該持續投入人力資源之培養，以及對醫院流程資源之改善，並分析這些資源的優缺點，才能有效的利用現有資源來提升放射科與醫院整體競爭優勢。 The purposes of this study are to explore the relationship between PACS (Picture Archiving and Communication Systems) and the radiology department's performance and to identify key resources in enhancing the performance of PACS in Resource-based View. The survey methodology was conducted with subjects being radiologists coming from 18 medical centers that had adopted PACS. Totally, 210 questionnaires were sent and 64 valid questionnaires were collected. The results revealed that hospital resources, including human resources and business resources, have significant effects on PACS performance; however, the relationship between PACS resources and PACS performance is insignificant. Furthermore, PACS performance shows a direct effect on the radiology department's performance. Based on the results, a follow-up interview was conducted and other underlying factors influencing the performance of PACS were proposed as well. Our findings imply that top management of hospitals should pay much attention on developing and analyzing hospital's existing human resources and business resources in order to understand strengths and weaknesses of these resources and to cultivate unique core competency. Thus, effective utilization of existing hospital resources can help in increasing the overall competitive advantage of radiology department and hospital.
