Anti-graft authorities across the country last year received more than 1.95 million allegations of corruption and agreed to investigate 172,532 cases, said Huang Shuxian, a deputy head of the ruling party's Central Commission for Discipline Inspection, at a briefing.
Huang said that as a result, a total of 182,038 officials were given disciplinary punishment, which can range from a mere warning to expulsion from the Party or worse.
"Disciplinary authorities at all levels... upheld imposing punishment upon all the corrupt," he said.
Communist chief Xi Jinping has taken a much-publicised hard line against graft since coming to power a little over one year ago, warning that corruption could destroy the party.
Graft causes widespread public anger and Xi has pledged to stamp down on high-ranking officials, or "tigers", along with low-level "flies" to maintain the purity of the organisation.
At the same time he has mounted an austerity drive, with a range of measures including limits on banquets and bans on gift-giving.
So far at least 19 officials at vice-ministerial level or above have fallen since November last year, including Jiang Jiemin, head of China's state-owned assets watchdog, and Li Dongsheng, formerly a vice minister of public security.
But critics say no systemic measures have been brought in to curb endemic graft.
