在知識經濟時代中，經由知識的創造、傳遞與應用獲得創新、異質性的知識和技術，對於產業競爭力的提升具有關鍵影響力。而生物科技產業擁有知識密集、產學互動關係密切、重視創新研發活動的特性，亦與本研究關注知識創新活動相符。加上生物科技的發展，不僅是全球大力投入的新興高科技產業，同時也被定位成國家競爭力的新指標。 所以本文即以生物科技產業為對象，從創新系統脈絡所提及的地理鄰近性和網絡關係切入，透過因素分析及系統分析（SEM）方法分別建構出在生技產業中創新系統行動者--廠商、大學和研究機構的知識傳遞路徑模型。透過所建構出的知識傳遞路徑模型，觀察在廠商和學研機構的知識傳遞活動中，同時考量地理鄰近性與網絡因素前提下，兩者對於知識傳遞路徑的影響程度及其所產生直接或間接的影響、與彼此間的因果關係所形成影響路徑的先後順序，以及地理鄰近性和網絡關係間是否可能存有互補或替代關係。更進一步針對產學研三者間的知識傳遞連結關係進行整體性的結構分析。 研究結果發現： 1.知識傳遞路徑確實存在先後因果關係引發對知識取得直接或間接之影響。在廠商模型中只有廠商聚集直接影響知識取得；而學研機構模型中則是由廠商鄰近與產業網絡直接影響知識獲取。並且因為因果關係的存在而形成知識傳遞路徑的先後順序。 2.在兩個知識傳遞路徑模型中，大學與研究機構都扮演主導創新研發活動的重要角色。 3.在廠商模型中，地理鄰近性與網絡存有互補關係，學研機構模型中則否。 4.地理空間的聚集對於廠商和學研機構的知識取得都具有舉足輕重的地位。 / During the era of knowledge-based economy, acquirement of innovative and heterogeneous knowledge by knowledge and technology creating , transmitting and using has key influence to improvement of industry's competitiveness. Characteristics of Biotechnology industry, which conform to this research pays close attention to the knowledge innovation activity are knowledge -intensive , close interactions between industry – university and emphasizing innovative and research development .It is not merely a new developing Hi-Tech industry of global great input, but also the new index of national competitiveness at the same time . This thesis regards biotechnology industry as the research subject promptly, based on viewpoints of geographical proximity and networks to understand the relations between innovative actors -- firm, university and research institution -- and to construct out the route model of transmission through factor analysis and systematic analysis(SEM).According to route model , while observing in the activities of knowledge transmitting, find out the actors’ influence degree and exert a direct or indirect influence in the route model , and try to figure out geographical proximity may be complementary or substitute to the networks. Go still one step further to concern the structure analysis which among the firms, universities and research institutes. The result of study is found: 1.The causality of knowledge transmission exists positively in the route to cause direct or indirect influences on knowledge acquiring and form the priority order .Only it influences knowledge to be obtained directly that the firms gather in firm's model; geographical proximity and firm's network influencing knowledge acquisition directly while learning to university and research institution's model . 2.In both route model, the university and research institution all act as leading actor in innovative activities. 3.In firm's model, the geographical proximity has complementary relations with the network, which has opposite relation in university and research institution's model. 4.The gathering in the geographical space has a very important position in the process of knowledge acquiring to all innovative actors.
