一个政权执政的绩效、社会意识、政治统治的有效性及三者的良性互动是政权长期执政的的合法性基础。由于社会生态环境的变化,党执政的合法性基础面临新的考验,党维护执政地位必须巩固经济基础、拓展政治基础,夯实文化基础。 The performance of a political power, social awareness, the effectiveness of political rule and the positive interaction of the three are the legitimacy basis for the long-term power of the government. Due to the changes of social and ecological environment, the legitimacy foundation of the party in power is facing new challenges. To maintain its ruling position, the party must consolidate its economic foundation, expand its political foundation and consolidate the cultural foundation.
