Abstract: Grassroots “micro-corruption” is an important type of corruption. It is of great value for county-level supervisory committees to perfect the governance mechanism for controlling grassroots “micro-corruption”， to enhance grassroots people's sense of gains， and to foster a clean and honest grassroots political ecology. At present， county-level supervisory committees usually have the following problems when they conduct grassroots “micro-corruption” governance: the contradiction between the frequent occurrences of “micro-corruption” cases at the grassroots levels and the “three non-increase” of the supervisory force at county-level supervisory committees， the easy interference of personal Guanxi， and the increase of difficulties in “micro-corruption” governance as a result of collusion between grassroots officials and evil forces. In view of this， county-level supervisory committees need to start from the following three aspects when perfecting the governance mechanism for control of grassroots “micro-corruption”: enhancing corruption governance efficiency of county supervision committees by strengthening the inspectors training and the integration of internal organizations; taking comprehensive measures such as cross-examination and level-up jurisdiction to eliminate interference from basic human factors; combining “micro-corruption” governance at the grassroots levels with the special efforts of cracking down on evil forces.

Key words: county-level supervisory committee, grassroots “micro-corruption”, interpersonal interference, off-site cross-inspection, cracking down on evil forces
