"Perfecting decision-making information and intellectual support system" embodies the requirements of deeply understanding people's feelings, fully reflecting people's feelings, widely concentrating people's wisdom and earnestly cherishing people's resources, which has important practical significance. Perfecting decision-making information and intellectual support system is the objective need to establish socialist democratic politics. With the increasing diversification of social structure and interest pattern, different interest groups have taken shape in our society. They have their own demands and try to express their opinions through various channels. At present, whether it is institutionalized channels such as people's congresses and CPPCC at all levels, or various news media, institutions and social organizations, it has become a way to understand and reflect public opinion. In addition, people can also express their ideas through the Internet and short messages. Of course, the party and the government can also understand and listen to the voices of those groups that are temporarily blocked from the modern information network through other channels.
