Is it malicious collusion that the property instigates the owner to sue the industry Committee?

Whether it is malicious collusion depends on the situation.

First of all, if the property company instigates the owners to sue the industry Committee out of malice, subjectively, it has the intention of colluding with others to carry out malicious litigation, then this behavior can be identified as malicious collusion.

Secondly, if the property company instigates the owners to sue the industry Committee for the purpose of legitimate rights protection, and there is no malicious collusion with the owners objectively, then this behavior cannot be considered as malicious collusion.
