新北市中港河廊建設是北新莊的重大公共工程，其為早期的灌溉渠道，穿越舊市區並串接至現今副都心計畫區位置。中港河廊見證了新莊都市發展，同時扮演連結在地居民共同記憶的重要角色。整治後的中港河廊帶狀綠地為新舊社區鄰里民眾互動交流之重要場域，而設置於其中，高達兩仟萬設置經費的公共藝術也為地方增添藝文風情。本研究探討民眾對中港河廊公共藝術設置之認知與偏好，回顧規劃設計、民眾參與創作至觀察現況維護管理，接續以半結構式訪談、非參與式觀察提出假說，再藉由公共藝術著重之「公共性」、「藝術性」與「場所性」三大特質所區分之『可親性』、『地緣性』、『與環境融合』、『互動性』、『多樣性』、『藝術性』、『地方依賴』與『地方認同』等八項認知因子作為研究變項進行大眾問卷調查，深入探討河廊使用者對公共藝術的認知與偏好。透過平均數、標準差、重複量數單因子變異數分析、簡單線性相關分析法進行分析後發現，現況三件永久性公共藝術在民眾認知以及偏好上呈現明顯差異，推論作品之色彩、量體規模、醒目程度及觀賞距離應是主要關鍵所在。同時發現，設置完成後之民眾參與程度明顯偏低，使得公共藝術作品常遭忽略，無法彰顯其蘊含的意義與內涵，顯示參與設置過程的互動與設計概念傳達是公共藝術設置成功與否的重要影響因素。

The Zhong-Gang Canal in Xinzhuang Dist, New Taipei City, is an important public construction of the north Xinzhuang district. Zhong-Gang Canal drew water from Dahan River in agricultural period and ran cross the old district to the present Sub-urban center district. It was the water canal for the agriculture in many years ago, but turn into the canal of waste water when the urban sprawl to Xinzhuang Dist. It's not only the sign of Xinzhuang's landscape change, but also the collective memory of local residents. After the improvement of Zhong-Gang Canal's environment, the green corridor space has become an important place where the residents who live in old & new communities to communicate with each other. And the installing fee promotes not only amount and quality of the art works, but also increases the art atmosphere of the local area. This research is working on the citizen cognition and preferences of Zhong-Gang Canal’s public art, intends to understand the real interaction of residents from the initial planning period, citizen participate in installing public art process, to maintenance period. This research adapts the research methods of ＂semi-structured interview＂&＂nonparticipant observation＂ to propose the hypothesis and use ＂questionnaire＂ to conduct a survey of the Zhong-Gang Canal user's public art cognition and preferences. This research finds out the existed three permanent art works have the obvious differences in citizen cognition and preferences. The place where installs public art, the scale of art works and the eye-catching present ways are the key points in installing public art. At the same time, this research’s result find out the citizen participation degree is obviously low. This result shows people pay little attention on public art, so they can't understand the significance of art works. It means the interaction of the installing process and the design concept are the key factors to decide the success of a public art. Finally, we find out the strong relationship between cognition and preferences from the result of the survey. It means the fabulous public art is not only have to satisfy the requirement by law, but also have to improve citizen to understand the art works and get more preferences & identity.
