Several communities in Jiangxi Province jointly set up industry committees.

In China's legal system, the establishment of community committees is a mechanism to manage property affairs through voluntary organization and participation of owners. According to Article 15 of the Regulations on Property Management, owners can set up owners' committees according to law to exercise the rights and fulfill the obligations of property management.

For the joint establishment of industry committees in Jiangxi province, the specific provisions will involve local property management regulations, election methods for owners' meetings of residential quarters and other documents. It is common that when there are many owners facing management problems in a residential area, the owners can unite to form an industry Committee to negotiate and make decisions and participate in the management affairs of the residential area.

Therefore, if several communities in Jiangxi Province have the same management needs and meet the standards for establishing industry committees stipulated in relevant local legal documents, then owners can set up community industry committees by convening owners' meetings and holding elections as required. Specific details and procedures also need to refer to local regulatory documents.

If you are in doubt about the specific procedures and requirements, it is recommended that you consult the local real estate management department or professional property management company, or consult the relevant regulations and measures issued by the local government or relevant departments.
