The present invention relates to an ethylene &#x3b1;-olefin copolymer having a narrower molecular weight distribution, and a uniform distribution of comonomer. The ethylene &#x3b1;-olefin copolymer according to the present invention has a uniform comonomer distribution and exhibits a lower density in the same comonomer content, unlike conventional ethylene copolymers having a random or blocky comonomer distribution.
