Linear α-olefin is an important feed stock for chemical industry. Production of specific α-olefin through selective ethylene oligomerization catalyzed by homogeneous chromium-based catalysts is an important research on orientation under rapid development in recent years. The research of catalytic mechanism plays an important role in guiding the exploration of novel high-efficient catalysts. The application of methods such as labelled atom, organometallic precursor, EPR-XAS, density functional theory (DFT) calculation etc. in the research of reaction path and the metal oxidation state is introduced, with the latest achievement in the mechanistic research summarized. Research works carried out by various researchers are compared and discussed from methodology. New perspective on binuclear Cr metal ring mechanistic research is proposed and an outlook on the further research orientation is presented.

Key words: ethylene, chromium-based catalyst, metal complex, catalyst activation, selective oligomerization, mechanism research
