Abstract:	隨著網路時代的來臨，人們透過網路搜尋資訊及交易的頻率大為增加，相關數據之數量及種類也大幅成長，這些數據雖細碎龐雜，卻記錄著人們自搜尋、瀏覽至交易行為決策之過程。以往我國之不動產研究或政策擬定，資料來源多來自官方、民間企業或學術統計為主，這些資訊雖給予政府或企業分析、預估市場一定程度之基礎，然其資料背景不同且發布時間落後，於資料使用上仍存有諸多限制。而搜尋引擎具有即時性、隱含潛在經濟活動意象之特性，應可補足過去統計資料之不足，提供不動產市場更即時、精確之預估。本研究以自 Google Trends 搜集之搜尋引擎指數作為自變數，加入傳統不動產市場之計量模型，同時探討其與住宅交易量與價格間之關係。結果發現 Google Trends 指數對於房地產之價格及交易量均存在顯著領先之關係。研究建議未來分析可藉瞭解搜尋引擎之大數據與房地產市場間之關聯，可提升在不動產市場資訊或預估之即時掌握，俾供政府擬定政策或企業、民眾決策時之參考。 With the increasing popularity of the internet, people acquire information frequently via internet. Data of searching and trading activities on internet accumulate sharply. These data, although fragmented, record people from search, browse and decision-making process. Traditional analysis of real estate market or policy making rely on statistics published by governments, companies, or academic institutions. Although these data provide some basis information, there are still some restrictions, i.e., limited sample and delayed posting. Data on search engines may complement these flaws. They are extremely timely and cover a great variety of economic activities, providing prompt and accurate forecast for the markets. This study applies the search engine index provided by Google Trends to explore the relationship between the search engine index and housing markets. Results show that search engine index significantly leads housing prices and transaction volume, indicating that people tend to search and obtain information before entering real estate markets. By understanding the leading effect of ＂big data＂ on search engine to the housing markets, we can forecast real estate markets more accurately, and provide more timely implications for governments, enterprises and the public.
