本研究根據社會網絡理論的雙重鑲嵌與雙元套繫之觀點，探討同時鑲嵌於垂直供應網絡與水平競爭網絡中的廠商，其在兩種網絡中所發展的套繫形式(強套繫與橋接套繫)對吸收能力(潛在吸收能力與實現吸收能力)之影響。經本研究實證結果發現，廠商在供應網絡與競爭網絡中的橋接套繫對於潛在吸收能力有顯著影響，而競爭網絡橋接套繫對潛在吸收能力的影響高於供應網絡橋接套繫；廠商在供應網絡與競爭網絡中的強套繫對實現吸收能力有顯著影響，而供應網絡強套繫對於實現吸收能力的影響高於競爭網絡強套繫；同時兼具潛在吸收能力與實現吸收能力對廠商的創新績效有正向且顯著影響。最後，本研究就理論與實務意涵加以討論，並提出未來研究的建議。

Drawing from social network theory with dual embeddedness and dual ties perspectives, the main purpose of this study is to examine the differing influences of bridge ties and strong ties in the supply chain network and competitive network on potential and realized absorptive capacity. According to the empirical results, the bridge ties both in the supply chain network and competitive network are positively related to a firm’s potential absorptive capacity, while bridge ties in the competitive network are more powerful in improving potential capability. The strong ties both in the supply chain network and competitive network are positively related to a firm’s realized absorptive capability, while strong ties in the supply chain network are more effective in realized absorptive capability. Besides, ambidexterity (the product term of potential absorptive capacity and realized absorptive capacity) has significant affects on a firm’s innovative performance. Finally, we discuss implications of this research and offer suggestions for future research.
