隘口雖為新竹縣竹北市的一個小星，但無論從歷史開發，族群變遷、宗教信仰消長，乃至高鐵徵收造成人口強制遷移後的變化，均是歷史學家、社會學家或文化工作者最好的觀察點。一般學者或地方文史工作者對於竹北六家地區的研究，幾乎將大部分精神與焦點放在林姓家族的開發或其相關議題，本文所從事研究的地方，為清代閩客移民所墾植，與六家林姓家族的開發全然無關，對於六家開發的原貌，或許可呈現更多元的思維。 本文的研究方法，包括文獻閱讀分析法與田野調查法，全文共分五部分敘述：一、隘口地理位置及地名來源，從地名的來源看出此地區與原住民互動的緊張關係。二、以較宏觀的角度看原住民主體時代隘口地區的開發。三、清代閩客移民對於隘口開發的貢獻，本段除利用各學者的成果外，同時利用古地契等資料，索驥當時的開發情形。四、隘口閩客人士的宗教信仰：「伯公會」與「天公會」的消長及傳說。五、今 (癸未)年隘口天公戲的觀察報導。

　　　　　 Aikou【隘口】is a small sub-ward(a small administrative unit) in the Chupei Township Hsinchu County, but it has become a focal point for study by historians, sociologists, or culture workers for its historical development, growth of religious sects, tribal migrations, or the buildup of a high-speed railway system. Most researchers or historiographers normally focus their efforts on the expansion of the Lin-Clan or other related topics in their study of the six clans in the Chupei area. My study centers on the settlement of the migrants from Fukien province in the ging dynasty. It has nothing to do with the six Lin clans, but it will present broader perspectives on the clans in their future studies. My approach consists of analysis of historical documents and fieldwork findings. My paper is divided into five sections (1) the geographical location of Aikou(i.e. a mountain pass)and the derivation of the name and the enmity engendered between the migrants and the aborigines (2) the development of the Aikou area as inhabited by the aborigines (3) the contributions made by the Fukien migrants (My study is based on the findings and documents by many researchers as well as the title deeds of land holdings.) (4) the religions of the Fukienese in the Aikou area: the legends of the Patriarchy Order and the Divinity Order (5) my observation of their opera performance for gods in 2003.
