The present invention relates to a catalyst for manufacturing a synthetic gas from a natural gas by using carbon dioxide, and more specifically, to a catalyst useful for manufacturing a synthetic gas by means of steam-carbon dioxide reforming. The catalyst according to the present invention is manufactured by a method comprising the steps of: 1) manufacturing a zirconia and alumina support coated with lanthanum and cerium by wet or dry ball milling; and 2) mixing and firing a powder of the support in step 1) and a nickel powder. The ratio of hydrogen to carbon monoxide in the synthetic gas, which is manufactured by using the catalyst according to the present invention, can be controlled to 2.0+-0.2, thereby easily providing the synthetic gas which is efficient for producing synthetic petrochemical products (such as wax, naphtha, and diesel).
