  The compilation of published spectra of Galactic HII regions with available
diagnostic [OIII]4363 line has been carried out. Our list contains 71
individual measurements of 13 HII regions in the range of galactocentric
distances from 6.6 to 14.8 kpc. The oxygen abundances in all the HII regions
were recomputed in the same way, using the classic Te - method. The oxygen
abundance at the solar galactocentric distance traced by those HII regions is
in agreement with the oxygen abundance in the interstellar medium in the solar
vicinity derived with high precision from the interstellar absorption lines
towards stars. The derived radial oxygen abundance distribution was compared
with that for HII regions from the Shaver et al. (1983) sample which is the
basis of many models for the chemical evolution of our Galaxy. It was found
that the original Shaver et al.'s oxygen abundances are overestimated by
0.2-0.3 dex. Oxygen abundances in HII regions from the Shaver et al. sample
have been redetermined with the recently suggested P - method. The radial
distribution of oxygen abundances from the Shaver et al. sample redetermined
with the P - method is in agreement with our radial distribution of (O/H)_Te
abundances.
