自十九世紀末霍華德提倡「田園市」以解決倫敦市日益問題惡化的都市問題以來，新市鎮發展至今已有九十幾年的歷史。回顧各國開發新市鎮的經驗，多數新市鎮開發的結果被認為是失敗的。臺灣自中興新村開始，一連串新市鎮開發的成效都未盡理想，而日前為廣增國宅、打壓房價、並引導臺北都會區向北發展，淡海新市鎮被列為六年國建項目之一，積極開發。本論文擬以淡海新市鎮之開發目標與主要計畫內容為主，並對各國開發新市鎮的經驗加以檢討，期能找出新市鎮發展的趨勢，並對淡海新市鎮的開發目標與計畫內容有所建議。 　　本論文藉由各國開發新市鎮之經驗的文獻與臺灣地區開發新市鎮之成效的評估、次級資料的蒐集，對新市鎮的發展做一回顧，並歸納出新市鎮未來的發展趨勢，作為淡海新市鎮發展的指標；同時，藉由次級資料的蒐集與檢討，找出淡海新市鎮主要計畫的缺失與不足。 　　由本論文之研究結果顯示，新市鎮未來發展的趨勢應朝向大都會區的一環，成為都會區的一個據點，並與中心都市的機能互補，以提高新市鎮開發成功之機率。而淡海新市鎮之開發目標應朝向多機能的新市鎮發展，而非以單一的住宅機能為主；同時，淡海新市鎮在主要計畫中如土地分配不均、公共設施不足、交通設備缺乏等問題亟需改進，以提高該新市鎮開發之成效。 / Since Howard advocated the concept of "Garden City" for solving the deteriorating urban problem of Landon in the end of 19th century, it has been ninety uears in the history of new town development. The experience of new town development in most countries are, however, considered as failures. Starting from Chung Using New Village, a series of new towns have been developed in Taiwan, but wirthout many successes. In order to expand the housing construction to decrease price and guide the development of Taipei metropolitan area northbound, Dan Hai new town has recently been listed as one of the items of the Six-years National Investment Plan in Taiwan. The purposes of the research are to evaluate the experiences of new town development in various countries, to seek the trends of the devdiopment bassed on this evaluation ; and to make suggstions for the devedlopment goals and contents of the plan for Dan Hai new town. 　　In the research, we reviewed, through the literature survey of the experiences in various countries and the evaluation of effectiveness of new town development in Taiwan, the development of new towns in general. We then deduced, of the new town development in Dan Hai. In the mean time, bassed on the collection and evaluation of secondary data, we pointed out the flaws and insufficiency in the master plan of Dan Hai mew town. 　　The results indicated ehae new town development should be part of the metropolitan area, serving as a base conplementary of the function of the central city to increase the probability of success of the development. The development goals of Dan Hai new town should, on the other hand, be aimed at multifunctional new town development, not single, residential one. In the mean time, the problems in the master plan of Dan Hai new town, such as inequality in land distribution and insufficiency of public and transportation facilities, must be solved in order to increase the effectiveness of the development.
