策略聯盟是一個非常有彈性的組織結構，公司間可以透過聯盟的合作關係，快速地分享獲得在研究發展、行銷通路及產品製造上的資源、能力或機會。然而其不完整合約的特性，常使得策略聯盟的參與公司擔心可能暴露在聯盟夥伴投機性的行為的風險之下。除了雙方股權交換以抑制投機性行為之外（Pisano,1989），近年來，聯盟網路的機制是否能降低未來雙方投機行為及套牢問題發生之探討受到許多學者的矚目。本研究經由美國國內公司宣告策略聯盟時市場反應的探討，針對此議題提出以下的結論。我們發現策略聯盟的關係的確能為聯盟夥伴間創造正向的財富效果，與Chan et al.（1997）之研究結果一致。除此之外，本研究另一項結果為策略聯盟整體若位於網路組織高Centrality的位置時，則在新的聯盟宣告中之財富創造效果將會明顯大於Centrality低者。因此位於網路中心位置之公司，由於其背後所擁有豐富的資源、強大的資源流通優勢以及商譽維持的壓力等機制下，確實能穩定策略聯盟的關係，進而為策略聯盟之合作的創造綜效。另外，異業聯盟之關係，因不對稱的專業知識背景及互補性資源難以整合、移轉的原因之下，使得雙方投機性行為發生之可能性較同業聯盟之關係高，所以其策略聯盟所創造的綜效往往較同業聯盟者差（Chen et al., 1997）。然而，本研究發現Centrality的高低為一個新的策略聯盟是否能創造財富效果的一個重要因素，而且，相較於相同產業的策略聯盟，Centrality的高低與否在非相關產業的合作關係中扮演的角色更為重要。所以這表示儘管異業聯盟關係中易存在投機性行為及Hold-up問題，但只要合作夥伴處於網路組織重要地位時，此種投機行為將可受到抑制，並且雙方聯盟之關係將更穩定。
綜合以上，我們可知聯盟網路（Social Network）和雙方股權交換的機制相似，對於投機性行為有相當重要的約束力量。並且在策略聯盟案中，與位於網路組織較中心位置的公司合作時，其投機行為發生的機會將大幅降低，使得策略聯盟的機制更穩定，增加投資人的信心，並且為企業間的合作產生綜效。

This study analyzed 438 strategic alliances formed during the period 1990-1998. Using the event study and cross-sectional regression methodologies, we found that the announcements of strategic alliances by American firms create significantly positive wealth effect for shareholders. Consistent with our expectations, degree of centrality in the network is crucial to influence the performance of strategic alliance, especially in non-horizontal alliance. Besides, the firms that are centrally located in the alliance network have better performance in new alliance. Finally, like the equity participation, network is a useful mechanism to mitigate opportunistic behavior in Strategic alliance.
