Since ¡§Doi Moi¡¨ (renovation) begun in 1986, Vietnam has engaged in economic reform on an on-going basis in order to create a fruitful investment environment and attract foreign investors to engage in its market. As the total investment amount is over 19 billion US dollars, the role of Taiwanese investors played is more important than before. Notwithstanding that the investment environment in Vietnam has improved more significantly than ever, the enterprises¡¦ operation still has to bear considerable risk. Due to Vietnam¡¦s special single-party state constitution, for foreign investors, it is expected that the political risk is existed with the high feasibility of government change policies and ignore investors¡¦ benefits. According to this, the purpose of this research is to realize how the host¡¦s political risk influences Taiwanese MNEs¡¦ entry mode choice. As previous studies generally focused on the discussion of the relationship between political risk and entry mode choice, however, the moderating effects of firms¡¦ own resource and advantages are less mentioned. Therefore, this thesis tries to provide a theoretical framework based on resource-based view, eclectic theory and other related theories that includes profitability, financial structure, and R&D capability as the contingency factors to examine how these factors moderate the relationship between political risk and entry mode choice. The findings of this study reveal that when the political risk in Vietnam getting higher, Taiwanese MNEs are more likely to engage in Vietnam through JVs. Besides, the positive moderating effect of profitability is also existed. It shows when a firm with higher profitability, it will more tend to choose JVs as the political risk in Vietnam rising.

在智慧財產權受到高度重視的現代，加上科技的發展日新月異，企業需要投入的研發資源和面臨的風險愈來愈高；因此，過去企業獨立進行技術研發可能不再是一個最佳的策略，取而代之的是越來越多專利聯盟的出現，而專利聯盟又會涉及到法律與管理層面的議題。 過去在專利聯盟的研究中，有關專利聯盟與反托拉斯法之間的關係，一直是法律學者所關注的焦點；而專利聯盟也受到各國主管機關的高度管制，深恐專利聯盟的形成，會對技術市場和產品市場造成限制競爭的情形，給產業競爭帶來負面的影響。然而，無論是法律學者或主管機關，在討論專利聯盟帶來的影響時，主要仍以論理的方式進行，鮮少以實證研究來探討專利聯盟。植基於此，本研究擬以實證的方式討論專利聯盟對於企業研發績效之影響。 而在策略聯盟的相關理論中，企業形成策略聯盟的原因包括為了取得重要資源、分散研發風險等目的。專利聯盟係一種由技術所組成的策略聯盟，專利聯盟若無法帶給企業益處，則該聯盟不可能持續存在。本研究以 MPEG-4 Visual 專利聯盟為探討對象，將企業的研發能力、加入專利聯盟時間的長短與企業的規模做為研究變數，討論其對企業研發績效的影響。 本研究以 MPEG-4 Visual 專利聯盟內的21家企業做為研究樣本，蒐集這些企業在2004年至2011年之間的專利申請數量、企業營收等資料。研究結果發現，企業的研發能力與加入聯盟後的研發績效呈現正向關係，亦即企業加入專利聯盟後，透過關鍵技術的交換，確實能夠提升研發能力，而且本身研發能力愈好的企業，其研發績效也會愈好，至於企業加入專利聯盟後的時間愈久，其研發績效也會有顯著的提升。然而，企業的規模與研發績效之間則呈現負向關係，造成此現象的原因，推論係因為規模越大的企業在研發資源的分配上較為分散，故反而降低企業在該領域的研發績效。
