The present invention provides a method for preparing an olefin polymer which can exhibit excellent isotacticity in a high yield and thus is suitable for use in reinforcing a long fiber, and a long fiber comprising an olefin polymer produced according to the above preparation method. In the preparation method, there can be provided an olefin polymer having excellent isotacticity in a high yield can be obtained by using a supported catalyst in which a transition metal compound having a specific structure is supported on a carrier together with two kinds of cocatalysts. In particular, the supported catalyst can exhibit high activity, excellent process stability and high hydrogen reactivity, thereby providing an olefin polymer having a high flow rate with a regular and excellent morphology. Such olefin polymer exhibits high processability while having excellent mechanical properties such as a tensile strength and a flexural strength, and thus are very useful as long fiber reinforced resins. They are used as long fiber reinforced resins and have an advantage in that total volatile organic compounds (TVOC) are significantly low as compared with those of general-purpose long fiber reinforced resins.
