最近二十年來，利用計量模型研究投資行為的理論甚多，其中以D. Jorgenson的新古典投資模型理論較為良好，它在美國的實證研究結果頗能解釋美國廠商的投資行為。
本文利用Jorgenson的投資理論研究唐榮公司的投資行為，視該公司的投資行為能否用Jorgenson的理論來解釋。Jorgenson的投資理論源於新古典投資理論，假定廠商以現值極大化( Present Value of the firm )為經營原則。廠商以現值極大代經營最後必獲得一資本勞務租用價格( Rental price of capital service)。由資本勞務價格與生產量兩者決定欲望資本存量(desired capital)。欲望資本存量的變動即為淨投資的成因。淨投資每每有遞延落後分配的情形發生，Jorgenson採用的遞延模型稱為合理遞延落後模型(Rational distributed Lag Model )再加上替代投資的設定以及稅收結構等，構成完整的投資行為模式。
本文取用的資料以季為單位，範圍取自民國五十五第一季至六十一年第四季唐榮公司的財務資料。利用Jorgenson的理論設定唐榮公司的季投資函數。
由第三章的實證研究的結果，得知Jorgenson的投資理論不大能解釋唐榮公司的投資行為。
