We are interested in the existence of Pareto solutions to the vector optimization problem
$$\begin{aligned} \mathrm{Min}_{\,{\mathbb {R}}^m_+} \{f(x) \,|\, x\in {\mathbb {R}}^n\}, \end{aligned}$$
where \(f:{\mathbb {R}}^n\rightarrow {\mathbb {R}}^m\) is a polynomial map. By using the tangency variety of f we first construct a semi-algebraic set of dimension at most \(m - 1\) containing the set of Pareto values of the problem. Then we establish connections between the Palais–Smale conditions, M-tameness, and properness for the map f. Based on these results, we provide some sufficient conditions for the existence of Pareto solutions of the problem. We also introduce a generic class of polynomial vector optimization problems having at least one Pareto solution.
