To provide a catalyst composition used in a catalyst system for ethylene oligomerization, having high activity and capable of generating a linear oligomer product having a wide weight percentage distribution, that is, of generating 4-16C linear oligomer products.SOLUTION: A catalyst composition includes zirconium amide compounds, organic aluminum compounds and an additive. The zirconium amide compound has the expression of ZrXm.n(RCONR'R") (here, X is a halogen atom; m is an integer of 4 or less; n is a number of 2 or less; and R, R' and R" are saturated or unsaturated 1-10C aliphatic hydrocarbons or 6-14C aromatic hydrocarbons).SELECTED DRAWING: None 【課題】エチレンオリゴマー化のための触媒システムに用いる触媒組成物であって、高い活性を提供し、広範な重量パーセント分布、すなわちＣ4からＣ16を有する線状オリゴマー生成物を生成する触媒組成物を提供する。【解決手段】触媒組成物は、ジルコニウムアミド化合物、有機アルミニウム化合物、および添加剤を含む。前記ジルコニウムアミド化合物は、式ＺｒＸm．ｎ（ＲＣＯＮＲ'Ｒ"）を有し、ここでＸはハロゲン原子であり、ｍは４以下の値を有する整数であり、ｎは２以下の数であり、Ｒ、Ｒ'、およびＲ"は飽和または不飽和脂肪族のＣ1−Ｃ10炭化水素、または芳香族のＣ6−Ｃ14炭化水素である。【選択図】なし
