摘要:	本研究針對公告年1976年1月13日至2014年3月11日持有太陽能光伏專利之上市上櫃廠商，利用Freeman (1978)之集中度作為專利品質，衡量專利在整體網絡中的重要性，並進一步使用Hall et al. (2001)提出之The “fixed-effects” approach調整專利引證機率，加入專利特性與廠商特性，探討廠商持有專利之網絡集中度對於其生產力是否有影響。實證結果發現，第一，專利網絡集中度對於生產力有正向的影響，尤其為入度點度中心性與入度接近中心性最為顯著，表示專利被引證的次數對於生產力具有強烈的影響；第二，經由調整專利引證機率後之點度中心性的係數皆上升；第三，專利申請範圍與生產力為顯著正相關，表示在專利提繳申請時，申請範圍越多對其生產力越高。;This study is aimed at measuring firms patents quality in the overall network by using the centrality of Freeman (1978) from January 13, 1976 to March 11, 2014, which holding photovoltaic patents. Furthermore, use the "fixed-effects" approach by Hall et al. (2001) proposed to adjust the probability of patent citation, including the patent features, firms characteristics, and discuss whether the network centrality of the patent held by the firms has an impact on its productivity. The result show that the degree of patent network centrality has a positive effect on productivity, especially the indegree centrality and incloseness centrality is significant, indicating that the number of patents cited has a strong impact on productivity. In addition, the coefficient of centrality after the probability of adjusting the patent is increased. Besides, the scope of patent applications and productivity is significantly positive correlation, indicating that more the scope of the application of its higher productivity.
