經濟學於1776年亞當‧史密斯撰寫「國富論」後，正式成為一門研究人類經濟行為的社會科學，過去兩、三百年來，世界各地有無數的學者投入經濟學的研究與教育的工作，學者在傳授經濟學時需要良好的輔助工具，一本優良教科書站在經濟層面的觀點上，其價格訂立為最重要的關鍵。因此本研究以民國40年～95年間所有國內出版的中文經濟學教科書為實證資料，建立一個長期經濟學教科書價格模型，藉由特徵價格理論研究教科書的各項特徵在半對數函數轉換模型與Box-Cox函數轉換模型下對於價格的影響。
實證結果發現，在半對數函數轉換下，章節、頁數、書籍寬度、書籍厚度與出版年份等特徵變數對於價格有顯著影響；在Box-Cox函數轉換下，各項特徵對價格的影響與半對數函數轉換的結果大致相同，並且可有效提高模型的配適值。

After Adam Smith wrote “The Wealth of Nations” in 1776, Economics became an official social science for researching people’s economical behavior, and there have now been numerous scholars researching and teaching Economics around the world for more than two hundred years. During their educational careers, these scholars need appropriate tools, and the price of Economics textbooks has become one of the most important factors in judging the quality and value for money of these resources. For this reason, we collected data from Economics textbooks in Chinese from 1951 to 2006, and built a long term differential pricing model to analyze the effects of the textbook characteristics compared to the price.
In this paper, we compare the empirical results of two functional transformations. When using semi-log transformation, we found that chapters, pages, page width and depth, and the year of publication affect the price significantly. When using Box-Cox transformation, we found the same results, but this is also effectively raised the value of the R-squire.
