近年來顧客行為在行銷領域被廣泛地研究，現在企業分析顧客過去的消費紀錄，找出顧客的購物模式以及偏好產品等購買行為後，投其所好來進行行銷。
而衝動購買(Impulse Buying)則是顧客行為研究最重要的議題之一。1962年美國經濟學家Hawkins Stern定義衝動購買就是沒有詳細計畫的購買，並在做了一系列市場研究後，將衝動購買細分為四種類型：純粹型(Pure)、提醒型(Reminder)、建議型(Suggestion)、與計畫型(Planned)。
在過去數十年間，資料探勘的技術與應用有著顯著的發展，但是將資料探勘技術應用於衝動購買行為的研究，卻是相當的乏善可陳。因此本研究目的在於利用資料探勘之技術找出衝動型購物的顧客，分析其購物行為，進而提出相對應的行銷策略。本篇文章提出了一套利用序列樣式的資料探勘方式，在界定的探勘資料取樣期間，找出顧客的衝動購買行為，以及該衝動購買行為的類型。所得到的結果，可以協助決策者制訂更好的行銷策略，激發顧客的衝動購買行為，以增進企業的營收。

Recently customer behavior has been extensively studied in the marketing field. Many enterprises analyze customers’ data and their transaction records to expose the customer purchasing patterns in order to develop the appropriate marketing strategies.
Impulse buying is one of the most important issues in studying customer behavior. In 1962, U.S. economist Hawkins Stern gave the definition of impulse buying as an unplanned buying behavior and divided this behavior into four categories: pure impulse buying, reminder impulse buying, suggestion impulse buying, and planned impulse buying.
In the past few decades, the technology and applications of data mining have been significantly developed. But there are seldom studies applying data mining technology to impulse buying. This article presents a sequential pattern mining approach to identify the impulse buying behavior of each customer and the category of his/her behavior. The mining results can help decision makers to develop better marketing strategies.
