Provided are a novel transition metal compound based on a cyclopenta[a]naphthalene group, a transition metal catalyst composition having high catalytic activity for preparing an ethylene homopolymer or a copolymer of ethylene and at least one &#x3b1;-olefin including the same, a method for preparing an ethylene homopolymer or a copolymer of ethylene and &#x3b1;-olefin using the same, and the ethylene homopolymer or the copolymer of ethylene and &#x3b1;-olefin prepared above. The metallocene compound according to the present invention and the catalyst composition including the same may provide a high thermal stability of the catalyst to maintain high catalytic activity even at a high temperature, have good copolymerization reactivity with other olefins, and prepare a high molecular weight polymer at a high yield.
