從專利引證相似度探討商業模式相互影響網絡與社群結構之研究－以台灣IC設計產業為例

專利引證常被用來衡量知識流學習效果，但我們發現它也可被用來衡量企業進入特定技術領域的意圖。廠商合力堆疊技術的同時，也成為各自潛在的競爭對手，因此，專利引證可以被用來衡量廠商之間商業模式的競合行為。一開始，我們定義專利引證相似度的量化衡量方式並得出一個廠商之間的相似性矩陣。藉著社群分析的方法，我們由這個矩陣中提取出它的社群結構及觀察其競合強度。我們最後分析它對規模與財務績效之關係的干擾效果。結果顯示，為了獲得更好的財務績效，大廠商需要減少它的競合強度，而小廠商則需要達到臨界的競合強度。

Patent citation is often used to measure the learning effect of knowledge flows. Furthermore, we find it could also be used to measure the intention of a firm to enter a specific technology field. While firms puzzle out technology together, they also become potential competitors with one another. Therefore, patent citation could be used to measure the co-opetition behavior of business model among firms. Firstly, we define a quantitative measurement of patent citation similarity and get a matrix from mutual similarity among these firms. By adopting community analysis method, we extract its community structure from this matrix and observe co-optition level of each community. We analyze the moderating effect of co-optition level on the relationship between firm scale and financial performance finally. The result shows that to attain better financial performance, large firms are inclined to decrease their co-optition level while small firms tend to increase to reach their critical co-optition level.
