Injective Rota–Baxter operators of weight zero on $F[x]$ were described in 2021. We classify the following classes of monomial Rota–Baxter operators of weight zero on the polynomial algebra $F[x,y]$ and its augmentation ideal $F_0[x,y]$:  1) non-increasing in degree and whose kernels contain no monomials, 2) mapping each monomial to a scalar multiple of itself. In the context of these classes of operators, we show how one may  define a monomial averaging operator by a given Rota–Baxter operator and vice versa.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оператор Роты–Бакстера</kwd><kwd>оператор усреднения</kwd><kwd>алгебра многочленов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Rota–Baxter operator</kwd><kwd>averaging operator</kwd><kwd>polynomial algebra</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда №23-71- 10005, https://rscf.ru/project/23-71-10005/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Guo L.
