知識經濟的時代，創新已成為廠商競爭優勢的主要來源。知識的創造、傳遞、轉化和應用，促成廠商創新活動的產生。同時，連結地域空間與廠商創新績效的研究，已成為近代區域經濟與產業發展的重要議題。又，研究者逐漸意識到廠商個體的異質性，進而探求個別廠商的內部能力，吸收能力即成為研究焦點之一。 基此，本研究以全台灣生物技術產業為研究對象，透過廠商問卷之發放，運用因素分析與結構方程模型為分析工具，探討鄰近性－地理鄰近性和組織鄰近性的內涵，以及吸收能力如何扮演外部知識與廠商內部能力的介面，並結合外部知識、內部吸收能力與創新績效之影響路徑。 所得結果如下： 1.從外部知識層面，地理鄰近性扮演重要角色。對於組織鄰近性、創新績效有正面影響效果。其中，組織鄰近性隱含了組織網絡與社會網絡的成分； 2.觀察外部知識與內部能力的連結，外部知識獲取對於吸收能力有正面影響效果； 3.吸收能力對於創新績效亦有正向影響關係； 4.然而，考量到外部知識因素時，吸收能力對於創新績效的效果轉為正向卻不顯著，外部知識直接影響創新績效。 關鍵字：地理鄰近性、組織鄰近性、產業網絡、吸收能力、創新績效 / In the knowledge-based economy, innovation has become a key source of firms’ competitive advantage.The process of knowledge creation, transmission, transformation and application promotes the innovative activities. Meanwhile, the link geographical proximity and innovation performance of firms has become a modern issue of regional economic and industrial study. Also, the researchers gradually realized that the heterogeneity of individual firms, and then pay more ateentionon the internal capabilities of individual firms, thence the absorptive capacity seems to be a decisive element. Our research regards bio-technology industry as the subject promptly.Through sending questionnaires and using factor analysis and structural equation modeling as analysis tool, we observe “proximity” – the nature of geographical proximity and organizational proximity, and how can absorptvie capacity play the interface role between external knowledge and internal capacity, and further connect the external knowledge with internal absorptive capacity and innovation performance. The major results of study were found: 1. In the respect of external knowledge, geography proximity plays a crucial role in affecting organizational proximity and innovation performance. 2. External knowledge has a positive influence on absorptive capacity. 3. On the other hand, absorptive capacity affects the innovation permance of firms. 4. However, concerning the external knowledge, absorptive capacity results to positive but not significant on innovation performance.It implies that external knowledge directly impacts on innovation performance.
