Abstract: Group corruption organization network is built through the interactive relationship formed by the exchange of corruption among members. Interest exchange and emotional interaction are two logical mainlines that guide the organizational operation. On the one hand， the productive exchange structure， as the internal structure built around resource benefits， promotes and maintains the organizational operation， and the desire for profit drives members to seek resources by way of exchange and cooperation; therefore， resource income and capital reproduction are the internal drives; On the other hand， influenced by the interpersonal structure in traditional Chinese society， the process of organizing corporate corruption is actually constrained by human factors such as responsibility， obligation and commitment. Interaction logic， behavior pattern and role positioning among members are partly shaped by the external environment， so social construction which is based on relational structure is the external drive. Under the combined effect of the internal drive that pays attention to the pursuit of profit and the external drive that emphasizes norm and stability， group corruption has become an interest-emotional community.

Key words: group corruption, driving mechanism, internal drive, external drive
