本研究將以互相依賴的觀點觀察照明產業中廠商的夥伴關係，並以W照明公司之案例及其配合10家以上的供應商及訪談，探討照明產業供應鏈中，公司間的互相依賴度與夥伴關係管理策略之關聯。 研究者藉由文獻探討、個案分析與深度訪談之方式，瞭解及探討照明產業供應鏈中製造商與各供應商的互相依賴現況，以及在不同互相依賴程度下，製造商運用的夥伴關係管理策略的不同，研究結果如下: 一、相互依賴的本質來自於社會交易或資源依賴，相互依賴的程度可從買賣雙方的交易內涵、替代性及專業來判斷，如果買賣雙方有多年的交易關係，雙方至少是「賣方主導」以上程度的相互依賴性。 二、買賣雙方不同程度的相互依賴性，自然會影響買方夥伴關係管理策略之施行。 三、買方之夥伴關係管理策略可以有三方面的作為：夥伴關係類型的建立、夥伴關係階段的發展及夥伴關係評估指標的運用。雙方往來的頻率愈頻繁且時間愈長，買方愈可能對賣方建立型三的夥伴關係。雙方往來時間短則可能停在可靠階段；若雙方往來時間愈長，則愈可能進展到應變甚至創新階段。合作時間不長，買方通常會運用短期指標;合作時間長，買方會採取較長期性及信賴性的指標。 四、相互依賴及夥伴關係之各項變數是可以形成一個整合性架構的循環關係，此架構描述了交易內涵、替代性及專業性決定了買賣雙方之相互依賴程度，而相互依賴程度又和買方的夥伴關係管理策略有密切的關係，在買方實行了夥伴關係管理策略一段時間後，又會造成交易內涵、替代性及專業性可能的變化。 / This research studies partner relationship in lighting industry from the interdependency perspective. By interviewing 10 suppliers and analysing case dara of A lighting company to explore interdependecy and partnership management strategies in the lighting supply chain of A company and it's suppliers, the research findings is as following: 1.
