One embodiment of the present invention provides a hot dip alloy coated steel material having excellent anticorrosion properties and a method for manufacturing same, the hot dip alloy coated steel material comprising: a base steel plate; and a hot dip alloy plated layer formed on the base steel sheet, wherein the hot dip alloy plated layer comprises, in weight%, Al: greater than 8% to 25%, Mg: greater than 4% to 12%, and the balance being Zn and other unavoidable impurities, and the surface X-ray diffraction intensity of the hot dip alloy plated layer satisfies relational expression 1 below. [Relational expression 1] 2000 cps ≤ X-ray diffraction intensity ≤ 20000 cps (where the X-ray diffraction intensity is M-N, M is the highest peak intensity in a section less than 2θ = 20.00-21°, and N is a peak intensity at 2θ = 20.00°.)
