We report the current understanding of heavy quarkonium production at high transverse momentum ($$p_T$$) in hadronic collisions in terms of QCD factorization. In this presentation, we highlight the role of subleading power corrections to heavy quarkonium production, which are essential to describe the $$p_T$$ spectrum of quarkonium at a relatively lower $$p_T$$. We also introduce prescription to match QCD factorization to fixed-order NRQCD factorization calculations for quarkonium production at low $$p_T$$.
