Jin Gaofeng, the report's main researcher, said the more effort the government makes in tackling corruption, the more cases are likely to emerge.
"Many cases do not involve just one official," he said.
"In many investigations by prosecutors or the disciplinary authorities, a graft network is found, and that's why the figures for such crimes are likely to rise further."
Most dereliction of duty cases, especially involving people taking bribes, have a "latent period" when prosecutors and disciplinary officers carry out their investigations, he said, adding that other related cases can emerge.
Jin, an associate professor specializing in criminology at the People's Public Security University of China, said the greater number of duty crimes coming to light is also thanks to whistle-blowers' reports or just hints of crimes being posted on the Internet.
Besides, prosecuting and disciplinary authorities conducted stricter investigations, and civil powers to battle the problem have also been expanded, he said.
There have been several high-level corruption or illegal behavior cases involving officials, exposed over the Internet. Jin highlighted two.
Yang Dacai, a former head of work safety in Shaanxi province, was relieved of his duties after Internet whistle-blowers accused him of amassing luxury watches. He was exposed after pictures showed him grinning at the scene of a road accident in which 36 people died.
There was also the case of Lei Zhengfu, then-Party chief of Chongqing's Beibei district, who was removed from his post after apparently featuring in a sex video, again exposed by micro bloggers.
Jin said these types of cases are likely to continue rising this year.
Yi Shenghua, a Beijing lawyer with more than 10 years' experience in dealing with duty crime, agreed that the focus will remain on such cases.
Last year, most cases involved bribe-taking, often involving land, demolition, or house transferals, he said, adding that he expected cases involving high-level officials and large sums of money to become a focal point.
But Zhu Lijia, a professor of government administration at the Chinese Academy of Governance, thought that as a result of some high-profile exposures, cases are unlikely to rise this year.
"Those who might have potentially taken bribes or been involved in corruption will think twice about it under the crackdown."
Previously, some disciplinary authorities had avoided investigating or prosecuting, despite knowing that officials were involved, because of the loopholes that helped many take bribes.
However, with the emphasis being placed on the subject during the congress, negative practices or ignorance of the issue will also be exposed, Zhu said.
"In other words, stricter supervision and investigation requires the authorities to come more into play."
