旁支整合策略乃企業為促進產業網路資源整合與策略地位提升所進行的「旁支事業投資」模式，目的在提升企業的網路競爭力。隨著產業競爭日益激烈，該模式的應用與重要性日益增加，但相關研究並不多見。基此，本研究以臺灣某紡織企業「旁支事業投資」歷程為研究對象，透過參與觀察與深度訪談等方式，揭露該模式如何為企業締造網路競爭力。研究結果顯示：「旁支事業投資」建構的多元能力有助於引發企業的「價值創新」行為；而居間的跨層次組織學習、動態化組織慣例等則有助於改善來自「網路慣性」的箝制。

‘Lateral business investment’ has gained increasing attention among traditional industries in Taiwan. It is a strategic model which helps create strong network competence through industrial network integration and strategic position change.
However, the benefits deriving from adopting ‘Lateral business investment’ have not yet been well documented. This research aims to conduct a longitudinal study on this issue via an investigation of a selected Taiwanese traditional fabric firm. A qualitative research methodology was applied in historical documentary data collecting, observations and in-depth interviews with key managers. The result suggests that the construction and application of multilateral capabilities play a crucial role in value innovation from the strategy of Lateral Business Investment. Whereas, the barriers caused by network inertia could be reformed via multilevel organizational learning process and dynamic organization routines.
