大都市憑著其高度的聚集經濟、高生產力，而不斷地吸引人口及產業的進入，造成小都市相對劣勢。面對此一現象，政府應如何擬訂一適宜之都市發展政策，實有深入研究之必要。因此，本研究欲探討都市規模與都市生產力二者間之關係，希望從都市生產力之觀點，能提供合適的都市發展政策，以供政府參考之用。 　　針對上述，本研究擬利用Alonso及Schaefer都市模型來探討影響台灣地區都市規模變化之因素，進一步利用Translog生產函數求其規模報酬，藉以判斷都市生產力之高低。最後，則利用Translog生產函數與資本、勞動二條報酬分額方程式透過ISUR來探討不同都市規模要素報酬之問題。 　　經本研究實證結果得到以下幾個結論： 　　一、外部因素如：周圍地區對都市中心產品之需求、生產更高階產品之規模效果是影響都市規模、生產力變化之重要因素。 　　二、從連續型生產函數可得台灣地區都市規模與都市生產力二者間有正向關係的存在。 　　三、因限資料問題，無法進一步分析台灣地區生產要素所得分配問題。 　　四、針對不同規模報酬狀態的都市，有以下幾點都市發展建議: 　　　1.面對處於遞減規模報酬狀態的都市，應透過階層的提高，吸引各種經濟活動的進入，以提昇其生產力。 　　　2.面對處於固定規模報酬狀態的都市，應減少政府干預政策。 　　　3.面對處於遞增規模報酬狀態的都市，應避免外部不經濟的產生。 / The advantages of large urban areas, such as high degree agglomeration economy、high production, attract the entrance of population and industries. Thar will result in the disadvantage of the small city. How does the goverment play? The purpose of this study is to discuss the relationship between urban size and urban area production. Further more, I would like to give some suggestions about urban development policy. 　　In this study, I uses Alonso's and Mills's urban model to discuss what kind of factor will effect urban size and production. Next, I judge urban production through the returns of scale of different urban hierarchy, and use the translog production and the share functions of capital and labour to discuss the income distribution offactors. 　　According to the result of this study, we have several solutions: 　　1.External factor will effect the change of urban size and urban production. 　　2.According to the continuous hierarchy, there is a positive relationship between urban size and urban production. 　　3.Because of data, we can't discuss the income distribution of factor in Taiwan. 　　4.Regarding urban development policies: 　　　(1) when urban area exhibits DRS, it is necessary to move up the hierarchy for continuing urban growth. 　　　(2) when urban area exhibits CRS, goverment should not interrept urban development. 　　　(3) when urban area exhibits IRS, goverment should not generate external diseconomy.
