An ethylene-copolymerized olefin copolymer having a high comonomer dispersion index, a preparation method therefor, an application thereof, and a composition comprising an ethylene-α-olefin copolymer are disclosed. The ethylene-α-olefin copolymer contains 70-95 mol % a structural unit derived from ethylene and 5-30 mol % a structural unit derived from α-olefin. The α-olefin is an olefin having 5-10 carbon atoms. The dispersion index RMD of the α-olefin structural unit in the molecular chain is greater than 102%. The ethylene-α-olefin copolymer has a high comonomer dispersion index.
