企業技術多樣化與綠色創新之關係：考慮知識網絡的調節影響

Does A Firm’s Technological Diversification Benefit Its Green Innovation Efforts? Considering the Moderating Impact of the Knowledge Network

隨著工業化導致環境持續惡化，及社會對環保議題的日益重視，綠色創新已成為當前企業的一項重要課題。根據既有文獻，企業擁有的技術組合通常被視為其技術創新發展的重要來源之一，且常受到他們知識網絡中所處位置的影響。然而，過去研究尚未探討綠色創新是否受到企業所擁有的技術組合及其在知識網絡中的位置所影響。為填補文獻缺口，本研究旨在了解企業的技術組合與其在知識網絡中的位置會如何促進綠色創新。以2000-2022年期間來自在美國上市的224家半導體企業為研究對象，本研究發現企業的技術多元化性有助於綠色創新的發生，而此關係會因企業在知識網絡中心性增強而被強化，但結構洞並未有顯著的調節作用。這些研究發現為我們理解企業內技術積累及其在知識網絡中的相對位置如何影響綠色創新提供了新的理論和實務意涵。

As the environment continues deteriorating due to industrialization and society pays increasing attention to environmental issues, green innovation has become crucial for contemporary firms. Based on the existing literature, a firm’s innovation stems from its technology portfolio and is often influenced by its position in the knowledge network. However, past research has not explored whether green innovation is affected by a firm’s technology portfolio and its position in the knowledge network. To fill this gap, this study aims to understand how a firm’s technology portfolio and its network position promote green innovation. Based on 224 semiconductor firms listed in the U.S. between 2000 and 2022, this study found that a firm’s technological diversification contributes to green innovation. This relationship is positively strengthened by the firm’s centrality in knowledge networks, while the structural holes show no significant moderating effect. These findings offer relevant theoretical and practical contributions to our understanding of how the accumulation of technology within a firm and its relative position in the knowledge network influence green innovation.
