According to the regulations, group buying institutions should organize group buying activities only after formulating the "Group Buying Convention" for commodity housing and reporting it to the Municipal Administration for Industry and Commerce for review and filing. The Convention on Group Buying should specify the conditions for participating in group buying, the rules for choosing a house, the payment and supervision of the purchase price, etc.
Group buying commercial housing should strictly implement the state's support for self-occupied and improved housing consumption, and curb the differential taxation of speculative investment housing consumption.
