Our study found that where administrative disputes are concerned, today’s Chinese citizens are by no means apathetic about the law. However, practical constraints mean that some of them resort to other means of dispute resolution than judicial or quasi-judicial procedures. In actuality, a two-track system exists in Chinese citizens’ resolution of administrative disputes; that is, they have the same level of demand for (quasi-) judicial channels and for Party/government channels in the resolution of disputes of this kind. In addition, different social groups show a great variety of preferences in terms of choice of channels for dealing with such disputes. On the basis of empirical research we argue for further reflection on the theory and methodology of this kind of research today and call on theoretical research and institution building to show a genuine understanding of and respect for citizens’ wishes.展开更多
