  "abstract": "Generalized parton distributions at large $x$ are studied in perturbative QCD approach. As $x\\to 1$ and at finite $t$, there is no $t$ dependence for the GPDs which means that the active quark is at the center of the transverse space. We also obtain the power behavior: $H_q^\\pi(x,\\xi,t)\\sim (1-x)^2/(1-\\xi^2)$ for pion; $H_q(x,\\xi,t)\\sim (1-x)^3/(1-\\xi^2)^2$ and $E_q(x,\\xi,t)\\sim (1-x)^5/(1-\\xi^2)^3f(\\xi)$ for nucleon, where $f(\\xi)$ represents the additional dependence on $\\xi$.",
