Abstract
The opportunities for public participation are increasing, but many of these are not working satisfactorily. So this paper reports the analysis of discussion dynamics from adopting concurrent discussion, as one of some solutions to this problem, as a case of the social experiments at real society. As a result of comparing of issues exchanged, total numbers of all discussion groups were almost the same, but issues about future plans at the concurrent sessions were more various and original than that at the plenary. And it was showed that many statements at plenary session continued former one consciously, many exchanges at concurrent session processed freely. These indicated that adopting of the concurrent sessions was effective for development of discussion.
