PROBLEM TO BE SOLVED: To provide a liquid phase olefin polymerization method for various polyolefin product preparation. SOLUTION: This olefin polymerization method includes steps of providing a reaction vessel system 200 containing a plurality of reaction vessels 202a, 202b, each of which is arranged in parallel defining an inner reaction region, supplying olefin-containing supply raw material and dividing the raw material into independent supply raw material flows 15a, 15b, introducing one independent flow of the olefin-containing supply raw material flows into the reaction region of each reaction vessel, making an exothermic olefin polymerization reaction of an olefin polymerization reaction mixture in each reaction region, independently circulating 20a, 20b the reaction mixture in each reaction vessel with a flow rate which is independent of an introduction flow rate of each flow of the supply raw material into the reaction region while making the exothermic olefin polymerization reaction, removing a crude polyolefin product flow from each of the reaction vessels, and forming a single crude product flow by mixing the crude polyolefin product flows.
