Theoretical derivation of the relation between radio surface brightness~($\Sigma$) and diameter~($D$) for shell-type galactic supernova remnant (SNR) at the adiabatic phase and radiative phase is investigated respectively in our paper. We find that a transition point exists in 30~pc between these two $\Sigma$-$D$ relations, which can be consistent with the statistical results made by other authors. In addition, we also obtain the statistical result of $\Sigma$-$D$ relation on 57 shell-type galactic remnants, which suggests that the best fit line of the $\Sigma$-$D$ relation should be slightly flatter than those proposed by some other authors before. An extra interesting result is that our theoretical derivation also implicates that a new state may exist between the adiabatic phase and radiative phase.
