Abstract: In modern countries,the democratic system is mainly reflected in representative democracy.People participate in public affairs through people's representatives,and the expression of public opinion has become the most critical link in the representative democracy system.The success of representative democracy depends on whether real public opinion can be expressed.The popularization of network technology has brought about great changes in the way of expression of public opinion.From the ways of expression on behalf of people's representatives and letters and visits in the past,various network channels have been expanded:web pages,Wechat,Weibo,short videos,public accounts,etc.,may become tools of expression of public opinion.In the new media environment,in order to promote the process of political democratization,we can make efforts to innovate democratic mechanisms so as to understand and respond to real public opinions rapidly.Public opinion is the sum of people's beliefs,attitudes,wills and emotions about various phenomena and problems in the society.Around the occurrence,development and change of social events,people's social and political attitudes toward social managers will intensify social contradictions and endanger social harmony.Although public opinion may be distorted,it also reflects real social problems.In the system design,public opinion response should be combined with democratic system innovation.To be specific,committees of "Public Opinion Analysis and Dialogue" can be set up under the Standing Committee of the National People's Congress and the Standing Committee at the provincial,municipal and county level to filter out real public opinions.Instructions can be given to relevant administrative,supervisory,judicial,and procuratorial organs to solve these social problems reflected in public opinions.Such a system design is conducive to timely understanding and responding to public opinion,speeding up the process of political democratization,better responding to public opinion,solving practical problems in people's lives,and enhancing social harmony and stability.
