Public Participation is a main quality factor to measure democracy. The goal of this research is to take a look at the concept in two political surroundings an authoritarian regime and a democracy: China and Germany. Protests as a way to achieve participation are included to observe the process of Public Participation as a whole. This process can be seen as one in which a society negotiates how it wants to live. Since Elisabeth Klaus defines public identically and developed a model of three levels of public the thesis relies on her findings to analyse participation. Both the model and Public Participation are the theoretic foundation and the research interest of the paper. They are exercised on two case studies to compare theory with empiricism the protest against a chemical plant in Xiamen and the protests against “Stuttgart 21”. Findings are that public participation and protests are capable of being successful in both contexts and are very similar in their realisation. Simultaneously the model of three levels of public is capable of describing Public Participation in both cases. Where weaknesses could be identified it was possible to get rid of them for example by solving the problem of including powerful circles which want to avoid the public process.
