以專利共被引分析法探討生物復育之核心技術

Patent Co-citation Analysis of Core Technologies of Bioremediation

本研究之主要目的為藉由美國專利商標局（USPTO）專利資料庫所檢索到的專利資訊，運用專利共被引分析（Patent Co-citation Analysis, PCA）及因素分析（factor analysis）方法來歸納、分類、萃取及定義主要的生物復育技術，以探討生物復育之核心技術架構及其技術研發趨勢。本研究內文規劃如下：第二章回顧相關文獻；第三章介紹目前生物復育產業現況；第四章解釋專利共被引分析研究方法；第五章說明本研究實證分析過程、結果及介紹關鍵技術；最後第六章作出結論與建議。研究結果顯示，生物復育技術主要的研究發展趨勢包括下列領域：厭氧分解法（anaerobic degradation）、好氧分解法（aerobic degradation）、厭氧脫氯還原分解法（anaerobic reductive dechlorination）、生物強化技術法（bioaugmentation）和生物通氣法（bioventing）。期望本研究結果可以提供給環保政策制定者或相關研究學者參考，並針對環境、經濟、科技、社會觀點等不同考量，以作為未來相應的生物復育技術發展之規劃建議。

The purpose of this study is to investigate the major research and development (R&D) trends of bioremediation technologies as well as to develop the core framework through USPTO patent information. The Patent Co-citation Analysis (PCA) method was employed to classify the patents of bioremediation and the factor analysis technique was used to extract and conclude the major technology fields. The remainder of this study was organized as follows. Section 2 reviewed relevant literature. Section 3 illustrated the present landscape of bioremediation. Section 4 described the methodology and procedure of PCA. Section 5 demonstrated the empirical analysis of this study and at the same time explained the core technology categories. Finally, Section 6 provided conclusions and suggestions. The research result showed that the major R&D trends cover the fields of anaerobic degradation, aerobic degradation, anaerobic reductive dechlorination, bioaugmentation, and bioventing. This study effectively applied the PCA method and factor analysis technique to classify the patents of bioremediation and identify the main technology trends. The result of patent information analysis could serve as a reference for the future R&D on bioremediation. It was suggested for future works to consider how different environmental, economic, technological and social scenarios lead to corresponding bioremediation technologies.
