This paper is devoted to the complete classification of global phase portraits of quasi-homogeneous but non-homogeneous coprime planar polynomial differential systems of degree. To prove our result, we firstly study the canonical forms for these systems. Then, the global topological structures of the systems having canonical forms are studied by using the quasi-homogeneous blow-up technique for the finite singularities and the Poincaré-Lyapunov compactification for the infinite singularities. Finally we perform a topological classification for the set of global phase portraits.
