Disclosed is a method for preparing a borate ester on the basis of a tricyclopentadienyl rare earth metal complex, the method comprising the following steps : uniformly stirring and mixing a catalyst, a borane and a carbonyl compound for reaction to prepare a borate ester, wherein the catalyst is a tricyclopentadienyl rare earth metal complex; and the molecular formula of the tricyclopentadienyl rare earth metal complex can be expressed as : Ln(Cp)3, wherein Ln represents a rare earth metal selected from one of lanthanide elements. The preparation method has a higher catalytic activity, mild reaction conditions, a product that is easy to post-treat, a short reaction time, a low catalyst consumption amount, and a good range of applicable substrates, and can be used for industrial production.
