The Relationship between the Mortgage Lending Variables and Housing Markets

近十年來，因投機需求、游資充斥等原因使台灣房價成長之上升趨勢明顯高於許多國家，房屋交易方面則呈現明顯起伏不定之走勢，台灣政府單位為達成物價穩定、金融穩定與經濟成長等目標並且避免金融危機再度發生，透過制定及執行貸款管制政策，期能有效抑制假性需求與房價上漲趨勢。 然而，貸款管制是否能有效抑制房價，過去未有文獻針對購屋貸款管制工具與房價及住宅交易量觀察長期趨勢關係並缺乏整體性探討，故本研究欲藉由探究貸款成數與購屋貸款餘額占國內生產毛額比率與住宅市場間是否存在長期、短期影響或其間因果關係，以得知是否政策的投入能夠確切影響標的、達成目標。 本文嘗試以 2000 年第一季至2016 年第二季之貸款管制工具變數及總體經變數資料，運用 ARDL Bounds Test、ARDL-ECM 模型及Toda and Yamamoto 因果檢定探究購屋貸款管制變數對於台灣住宅市場間之長期與短期動態關係及因果關係。研究結果顯示，購屋貸款管制變數對於房價及交易量有顯著之影響，尤其對於住宅交易量方面具有較為明顯之效果，因此，期望透過本研究對於台灣未來金融、房市政策規劃提出建議。Over the past decade, an abundance of money and speculative demand from the Quantitative Easing (QE) monetary policy drove the housing price in Taiwan to rise sharply, and the volume of housing market is unstable. To stabilize the financial markets, the government have formulated policies on housing markets and mortgage control to curb rising housing prices. In order to understand the effect of mortgage control on curbing housing price, this study examines the long-run and short-run relationship and causality effect among loan-to-value ratio and mortgage-to-GDP ratio and housing markets. This study used ARDL model, bounds test and Toda and Yamamoto causality to analyze quarterly data over the period 2000-Q1 to 2016-Q2. Empirical results show that mortgage control has significant effects on the housing market. Results further shown that the influence on the volume is more obvious than on the price. Results of this study provide precious policy implications for future housing financial sectors
