住宅空間次市場價格比例與市場規模之關係

PRICE RATIO AND MARKET SCALE RELATIONSHIP BETWEEN HOUSING SPATIAL SUBMARKETS

本文將住宅空間次市場價格與數量的關係，轉化為住宅空間次市場「價格比例」與「市場規模」的相互影響關係，並建立靜態與比較靜態理論模型。從理論分析得知，住宅空間次市場之間的市場規模與價格比例是相互連動的，且各次市場規模之間的關係，則同時受到整體市場預期景氣趨勢的同向影響，以及相互競爭的反向影響。實證分析結果顯示，未來台北市住宅市場規模將會逐漸縮減，台北縣住宅市場規模則持續擴大，且住宅價格比例也將逐漸縮小，但是兩住宅空間次市場的規模之間並不是完全的零和競爭關係，而是呈現齊漲齊跌的情況，顯示台北市縣住宅市場的競爭程度，低於共同反應預期景氣的相互拉抬程度。

This paper established the price-volume interrelation between different housing spatial submarkets basis through the housing price ratio and market scale. This approach provides a new point of housing market researches. Then we conducted an empirical analysis of the Taipei City and Taipei County housing markets. Finding that the competition between these two housing spatial submarkets is low. Furthermore, there is a signification correlation between market scale and price ratio fluctuation,.
