本研究係探討虛擬社群討論議題各個知識概念下，版主（議題發起 人）與回應者間社會網絡關係及其差異，首先採用正規化概念分析法了 解知識結構及各討論概念所占比重，再以社會網絡分析法探討版主與回 應者社會網絡關係。本研究於 Mobile01 論壇之汽車討論區收集共 304 筆 有效討論樣本，接著將討論樣本相似的知識概念彙整出 6 個討論概念，
依此 6 個討論概念為主概念，將討論樣本轉換為社會網絡指標，分析各 個討論概念間社會網絡指標差異及探討知識結構中父層與子層社會網絡 指標繼承關係為何。
從正規化概念分析研究結果顯示，價格和配備及外觀此兩項討論概 念為社群成員在議題中談論最多的概念，由此可知在大改款汽車討論區 中，多數社群成員對於價格、汽車配備及外觀造型相關議題較感興趣，
而油耗此討論概念比率最低，表示油耗相關議題社群成員較少提及，可 能原因為汽車剛上市，多數成員尚無油耗相關資訊或資訊不足，因此對 於油耗相關議題討論才會較少。
而從社會網絡分析研究結果發現，提及有關購買資訊相關討論議題 時，社會網絡指標皆為最高，表示在購買資訊相關議題討論中，社群成 員間討論緊密度較高且社群成員與版主的互動較為熱絡，可推論在購買

資訊相關的討論中，因版主多數考慮購車，所以在討論購買相關議題上 版主與成員間回應較積極，而社群成員因版主的積極參與，故成員在討 論互動上較熱絡，因此網絡緊密度和中心性也隨之較高；而在油耗的相 關議題討論中，其社會網絡指標皆為最低，表示在油耗相關議題討論中，
社群成員間討論緊密度不高且與版主討論並不熱絡，由此推論，在油耗 相關議題上，社群成員間較會以具資訊成員形成小團體討論，與版主互 動較不熱切，故網絡緊密度及中心性較低。
綜合分析結果，價格、配備及外觀和購買資訊此三項概念較多人談 及，且社會網絡指標皆較高，由此可知，在大改款汽車討論議題中，價 格、配備及外觀和購買資訊此三項討論概念相關議題為較多人感興趣之 方向，且參與討論之社群成員多會與其他社群成員互動且成員跟版主的 交流也是熱絡的，而油耗相關討論議題較少人談論且社群成員間討論緊 密度較低與版主間之互動較不熱絡，但是從回應量來看，在有關油耗的 討論議題中，平均回應量卻是六個討論概念中最高的，可見對於油耗相 關議題，部分社群成員的回應是熱絡的，可推論在油耗相關議題討論中，
並非所有社群成員互動皆不密切，仍有小部分成員會形成一小群組進行 討論。
另外，本研究針對虛擬社群大改款汽車討論區正規化概念點陣圖中 重要節點探討其父子層繼承關係。研究得出父層討論概念與子層討論概

念在繼承關係下，社會網絡指標會呈現多種變化，本研究根據正規化概 念分析點陣圖重要節點整理出主要三種繼承關係現象，第一種繼承現象 為，父層主導概念中社會網絡指標相對低時，子層概念交集其社會網絡 指標未必會受到正規化概念分析比率較高之討論概念影響；第二種繼承 現象為，父層概念其網絡指標無明顯差異時，其子層概念交集網絡指標 與父層概念相較高低變化不定；最後一個繼承現象為，父層討論概念其 網絡指標無明顯差異，而子層討論概念網絡指標下降，從上述三種主要 現象可觀察出，在繼承關係中子層網絡指標未必與父層網絡狀態相同，
子層概念網絡指標會呈現多種變化。
本研究可幫助汽車廠商及虛擬社群管理者管理網站之參考依據，在 汽車廠商的部分可了解虛擬社群成員所重視的知識概念（如：價格、配 備及外觀和購買資訊），廠商可將此三項概念列為競爭關鍵，以貼近顧 客需求；而虛擬社群管理者可依照知識結構設置討論區塊，亦可透過網 絡結構了解討論區塊討論熱絡程度。
第二節 未來發展與研究限制
在未來發展中在概念分類可更加以細分，本研究主要針對安全性及 裝修、性能、油耗、配備及外觀、價格和購買資訊此六項概念進行探討，
未來可將品牌及車款加入概念分類中，幫助汽車廠商及社群經營業者更

加了解顧客及社群成員所重視的討論概念。
而在研究限制的部分，因汽車款式眾多，且社群成員對於各家車廠 回應量差距甚大，無法將所有車款列入樣本收集，因此本研究以熱門大 改款汽車為主軸。
