Graft is the most common and refers to bribery, illicit kickbacks, embezzlement, and theft of public funds. Graft involves something of value given to, and accepted by, public officials for dishonest or illegal purposes. It include officials spending fraudulently or using public funds for their own benefit.
Rent-seeking refers to all forms of corrupt behaviour by people with monopolistic power. Public officials, through granting a license or monopoly to their clients, get "rents"—additional earnings as a result of a restricted market. Rent-seeking happens when officials grant rents to those in their favor. This is akin to cronyism. In the Chinese case, public officials are both rent-generators and rent-seekers, both making rent opportunities for others and seeking such opportunities to benefit themselves. This may include profiteering by officials or official firms, extortion in the form of illicit impositions, fees, and other charges.
Prebendalism refers to when incumbents of public office get privileges and perquisites through that office. Controlling an office entitles the holder to rents or payments for real or fake activities, and organizations are turned from places of work into "resource banks" where individuals and groups pursue their own interests. Prebendal corruption doesn't necessarily need to be about monetary gain, but may include usurpation of official privilege, backdoor deals, clientelism, cronyism, nepotism.
Corruption in the PRC has developed in two major ways. In the first mode, corruption is in the form of ostensibly legal official expenditure, but is actually wasteful and directed toward private benefits. For example, the increasing number of local governments building massive administrative office buildings that resemble luxurious mansions. At the same time, many corrupt local officials have turned their jurisdictions into virtual “mafia states,†where they collude with criminal elements and unsavory businessmen in illegal activities.
