It argues that, within the current public participation framework, neither the "bottom-up" active participation nor the "top-down" passive participation can generate satisfactory effects or mediate multiple interests, whereas a professional third party could effectively promote public participation by bridging the public with the government. Besides, the third party plays an increasingly significant role in maintaining public interest, particularly in a context where the government often overemphasizes economic interests and there is a ubiquitous lack of awareness among the general public.展开更多
