都會區空間結構之研究－－以台北、台中、高雄都會區為例

THE STUDY OF METROPOLITAN SPATIAL STRUCTURE -TAIPEI, TAICHUNG AND KAOHSIUNG METROPOLITAN AREAS-

本文主要利用三次雲形函數測試台北、台中、高雄三個都會區民國65年和78年間人口密度空間結構的型態及其變化。其間發現三個都會區有不同的空間結構型態及人口郊區化的現象，但郊區化的過程中亦存在明顯的差異性。在人口密度空間結構變化量上，本文利用二次方函數建立都會區空間結構變化模式，並透過影響都會區空間結構的解釋變數，發現所得因素是解釋都會區空間結構變化的一個變數，經濟產業活動在空間上的變化量和人口在空間變化量無關，該測試結果並形成未來都會區發展政策上應注意的課題。

This paper proposed to estimate the types and changes of population density spatial structure of the three metropolitan areas: Taipei, Taichung and Kaohsiung, during the year of 1976 and 1989, the cubic-spline function approach is applied. It is shown that there has a population suburbanization in the studied areas, while three metropolitan areas displayed three different spatial structure patterns. To explain the changing quantity of the population density, this paper using a quadratic function, to constitute a metropolitan spatial structure varying model, and find that income variable is a explanatory variable for metropolitan spatial structure change, and economic industry spatial changing quantity has no relationship with population density spatial distribution changing on metropolitan areas, and the policy implications of the explanations should be briefly discussed.
