英文摘要：

In this paper, we study the commutativity of Toeplitz operator and small Hankel operator on harmonic Dirichlet space. By the matrix representation of Toeplitz operator and small Hankel operator, we obtain the necessity and sufficient condition for Toeplitz operator and small Hankel operator on harmonic Dirichlet space to be commutativity, which extends the corresponding results on Dirichlet space.
