目標：探討現今台灣醫院聯盟網絡特質，並分析聯盟網絡之聯盟型態、產業與區域特質對醫院組織創新的影響。方法：以郵寄問卷方式，針對全國460家地區醫院級以上醫院之高階主管或聯盟管理者進行問卷調查，有效問卷回收率為35.45%，在檢驗樣本代表性、無反應偏差、共同方法變異與問卷信效度後，以階層迴歸進行驗證。結果：國內醫院有進行策略聯盟的醫院比率為85.18%，平均策略聯盟網絡規模為21.42家，醫院聯盟網絡不論在型態、產業與區域特質上皆具有相當的多元性，在這三種多元特質中，聯盟網絡型態多元性與地區多元性並無法對組織創新產生影響，而聯盟網絡產業多元性對管理創新乃是呈現倒U型的關係，然對醫院的技術創新卻呈現正向的直線影響。結論：醫院的聯盟網絡已相當多元，而在探討的網絡特質中，又以聯盟網絡產業多元性對於醫院創新的影響較為顯著，且此影響對管理創新與技術創新所發揮的效果是有所差異的。 Objectives: We placed our emphasis on exploring the characteristics of an alliance network and analyzing the impact of alliance pattern, partner industry, and partner location of an alliance network on the organizational innovation in Taiwanese hospitals. Methods: A self-administered mail survey was used to collect data. Questionnaires were sent to the top managers or alliance managers of 460 hospitals accredited as district hospitals and above. The valid return rate was 35.45%. After testing sample representativeness, non-response error, common method variance, questionnaire reliability, and questionnaire validity, we adopted a hierarchical multiple regression to analyze our research data. Results: The rate of alliance formation of Taiwanese hospitals has reached 35.45% and the average network size of strategic alliances is 21.42. Alliance pattern, partner industry, and partner location has become much more diverse. With respect to these three characteristics of diversity, the pattern diversity and the location diversity of an alliance network had no significant impact on the organizational innovation of hospitals. However, the industry diversity of an alliance network affected technological innovation linearly, but the relationship between this diversity and management innovation exhibited an inverse-U curve. Conclusions: The alliance network of hospitals has become much more diverse. In regards to several network characteristics, the industry diversity of an alliance network affects hospital innovation most significantly and has a different impact on management and technological innovation.
