In this paper, the unboundedness of solutions for the following planar Hamilton system Ju ′ = ∇ H ( u ) + h ( t ) is discussed, where the function H ( u ) ∈ C 2 ( R 2 , R ) is positive for u ≠ 0 and is positively ( q , p )‐quasihomogeneous of quasi‐degree pq , where p > 1 and $ 1 \over p $ + $ 1 \over q $ = 1, h : S 1 → R 2 with h ∈ L ∞ (0, 2 π ) is 2 π ‐periodic and J is the standard symplectic matrix.
