  The electromagnetic form factors of pion and nucleon are considered within
the framework of the Quark-Gluon Strings Model, where the dependence of the
form factors on $q^2$ is determined by the intercept of a dominant Regge
trajectory and Sudakov form factor. The analytical expressions for the form
factors found in the time-like region can be directly continued to the
space-like region. Good agreement with available experimental data on the pion
and magnetic nucleon form factor is obtained at positive as well as negative
$q^2$. It is shown that the difference in $F_\pi$ and $G_m$ at positive and
negative values of $q^2$ is mainly related to the behavior of the double
logarithmic term in the exponent of Sudakov form factor. The model describes
also existing data on the Pauli nucleon form factor $F_2$ and the ratio
$G_e/G_m$.
