China during the transition period, value diversity and class differentiation are prominent. In the grassroots society, individual's social role is also prominent, but there are certain conflicts among various social roles. At present, the role perplexity of leading cadres at the grassroots level is manifested as:inappropriate and improper role, the logical difficulty of role-playing, the practical difficulty of role-playing, the stigma of the social role of grassroots leading cadres in the context of network politics, the difference in sense of leadership between traditional and modern grassroots leading cadres and so on. In order to realize the transformation of the social roles of leading cadres at the grassroots level, and to reflect their service awareness and other objectives, we must strengthen the scientific decision-making ability, change the sense of official position to citizen awareness, resolve role conflicts through the rule of law, pay attention to the balance of role obligations and role rights and the top leaders' role game and contingency strategy, and establish a safeguard mechanism for the official-oriented to people-oriented transformation.
