Leonid Shneidman, chief of the ministry's financial control and auditing department, rejected expert opinion that the "Big Four" occupied at least half of the market.
"It is rather a mistake to say that the 'Big Four' dominate the market," he said.
Shneidman said revenues from auditing services made 24.1%, their share among other auditing organizations 1.5% and their audited clients accounted for 1.1%.
He also said auditing organizations' revenues increased 14% in 2006 to 32.784 billion rubles ($1.3 billion), but added that the figures were preliminary.
In Moscow, auditors' revenues from auditing services make up 40.7% of total revenues, 42.8% in St. Petersburg and 58.9% in other regions.
The official also said auditor organizations with at least five years of experience equaled 68.7%, and those with less than a year of auditing activities 2.7%.
Shneidman also said the auditing services market tended to shift in favor of smaller companies and concentrate mostly in Moscow.
