過去學者研究以直接觀察專利首頁上其他參考文獻(other references)段落引用學術論文的現象，綜觀得出科學與技術兩者之間存有關聯的結論 (Scientific Linkage)，然此類研究並未明確指出科學與技術兩者在發展軌跡上的關聯性及其關聯現象，亦即學術與技術的主要文獻是否也存有關聯，以進一步了解科學與技術之主要發展的關聯緊密程度。本研究透過連結專利與學術主路徑，找出兩者關聯性以及兩者於各自發展軌跡下的關聯程度，以補強過去分析法之不足，並藉此增加企業及研發者在技術發展時的知識參照標的，掌握關鍵知識加速研發，利於企業在快速變化的高科技產業中發展及生存。

隨節能減碳意識興起，相關電動車產業亦獲得市場重視，而其所含的電池技術中，磷酸鋰鐵電池相較其他電池，具有較高安全性、原料價格低、對環境無毒無汙染等優點，可望成為未來電動車電池發展重點。該電池發展由美國Goodenough教授於1997年首先在學術論文上提出，本研究以USPTO美國核准專利為研究範圍，運用主路徑分析法找出主要發展趨勢線，繼而對照專利主路徑文獻引用與學術主路徑的文獻關係，除以視覺化連線呈現兩個路徑的關係外並利用交叉比率分析探究其關係之強度。

研究結果顯示，主路徑汲取出的主要代表學術作者與專利發明人，都可對照出有相關之專利及學術論文的發表，顯示技術與科學間存有關聯。再由專利主路徑確實有引用學術主路徑論文現象，瞭解技術與學術發展之主要文獻的關聯性，其中，啟蒙論文被引用的情形相對明顯，研究結果亦得出專利與學術間的引用有國家引用偏好的現象；而從交叉比率分析可以證明專利主路徑 (關鍵技術) 引用學術主路徑 (關鍵科學) 的比率高於非專利主路徑 (非關鍵技術) 之引用，顯示技術主要發展與科學主要文獻知識傳遞間的關聯性高於非主要技術發展的關聯。

The linkage between science and technology has drawn much attention from many researchers in the innovation, general science and technology study field. Based on the citation frequency from patents to academic articles, researchers have shown the existence of strong connections between science and technology. This study provides further evidences on the linkage by examining the relationships between the core patents and academic articles of the lithium iron phosphate battery (LFP) technology. We collect 215 LFP patents from the United State Patent and Trademark Office database and conduct the main path analysis to identify the main development paths of the LFP technology (main path technology, MPT). These paths are then compared with the main development paths of the LFP science (main path science, MPS), which were obtained in the previous study from academic articles of the same field. The connections between MPT and MPS are presented visually and examined quantitatively. The results showed a relatively close relationship between MPS and MPT. Cross-ratio examinations revealed that in terms of ratio the MPT patents cited more MPS papers than non-MPT did. In other words, the relationship between core technology patents and science papers is stronger than that between non-core patents and core papers.
