Does anyone know what does this phrase "buy in into the process" in this context?

Question

Such a process of shared knowledge generation can advance that various actors BUY IN INTO THE PROCESS,
and can foster a process of overcoming mistrust and strengthen the formation of cooperative relations.

Answer 1

The phrase is "buy into the process" NOT "buy in into the process". It means that the various actors accept the process as being true and decide that it is a good plan, a good way to do things. They "accept ownership" of it as if they had thought of it themselves and act accordingly.
