摘要

在都市發展的過程中，究竟規劃與市場的力量是衝突或是調和，一直是規劃理論中持續爭辯的問題。就規劃而言，本質上可視作收集資訊以降低不確定性的決策制定過程；就市場而言，則是被視爲促成個體間短視而自發性交易秩序的合作過程。本文的看法是認爲，規劃與市場的最適分野其實與經濟意義上的財產權界定有關，而這種財產權的界定又取決於制度設計所產生的交易成本課題上。本文透過財產權經濟分析出發來解釋規劃與市場衝突的問題，並且以臺北市政府主動劃定更新地區的執行現況作爲個案研究，檢討臺北市目前政府主動劃定更新地區的推動困境以及未來應改進方向。

In the urban development process, it remains a controversial question in planning theory of whether planning and markets conflict or complement to each other. Planning can be viewed as gathering information to reduce uncertainties in order to make decisions, whereas markets can be considered as cooperative processes to induce transaction order derived from myopic, spontaneous exchanges among agents. The present paper considers the distinction between planning and markets as related to delineation of economic property rights, and such a delineation is determined by the transaction cost caused by institutional designs. Through economic analysis of property rights to explain the conflict between planning and markets, the present paper examines the implementation performance of the delineation of urban renewal areas by the Taipei city government and reviews the dilemma of the development of such areas and possible improvement strategies.
