Fach process includes several links which involve different democratic rights. To comprehensively promote the whole-process people’s democracy, it is necessary to make a detailed distinction between the democratic rights of each process, build a corresponding system and mechanism for the protection of rights, improve the ability of people in democracy, and establish the system and mechanism for evaluating the effect of democracy implementation.展开更多

文摘Theoretically, the whole-process people’s democracy involves five processes, namely, political process, policy process, urban and rural community governance process, enterprises and institutions management process, and international exchange process. Fach process includes several links which involve different democratic rights. To comprehensively promote the whole-process people’s democracy, it is necessary to make a detailed distinction between the democratic rights of each process, build a corresponding system and mechanism for the protection of rights, improve the ability of people in democracy, and establish the system and mechanism for evaluating the effect of democracy implementation.
