The Central Commission for Discipline Inspection (CCDI) said the officials, including two provincial and ministerial level officials, were implicated in over 3,800 cases, about a fourth of which involved unapproved use of public vehicles.
Unauthorised allowances and subsidies, lavish weddings and funerals as well as illicit gifts were included in violations.
The CCDI said in a routine report on its website that more than 4,900 officials were reprimanded in October.
The CCDI has established a monthly reporting system since August, 2013 to monitor the implementation of "eight-point rules" nationwide, which was introduced in December 2012 by the CPC to reduce bureaucracy, extravagance, and undesirable work habits.
According to CCDI, more than 71,000 officials were subject to disciplinary action for breaking austerity rules in 2014.
By the end of October, some 27,000 cases involving four provincial and ministerial level officials have been dealt with in the country's frugality campaign in 2015, it said.
