As the important agents of the grassroots construction of rural governance， village officials’ occupational behavior is not only a key part of ensuring effective rural governance， but also an important factor in realizing the modernization of the rural governance system and governance capacity. Based on multiple theoretical foundations， the article divides the village officials into two role types which are “serving the village”and “serving themselves” respectively， and three types of village officials’occupational behaviors， namely “serving the village rather than themselves”“seving both the village and themselves”， and “serving themselves rather than the village”. This paper discusses the influence of village officials’ roles on their occupational behavior tendencies， and uses case analysis to verify the heterogeneity of rural governance caused by village officials’ occupational behaviour tendencies. At the same time， based on the in-depth mechanism analysis of the behavior tendency of “serving themselves rather than the village”， we studied the formation mechanism of its typical behavior. The research found that in the village officials’ occupational behavior， due to their refined egoistic psychological choices and behavioral motives， they often take the maximization of their interests as the starting point and the end point of all behaviors and have the tendency to “serve themselves rather than the village” while they should have played the role of “serving the village” to represent the government and the villagers to safeguard the real interests of both sides. Therefore， two countermeasures were put forward to regulate the tendency of village officials’ occupational behavior. On the one hand， we should strengthen the supervision of village officials at the same level， improve the supervision mechanism of government behavior， and create a dual supervision system of upper and lower coordination. On the other hand， it is also important to improve the punishment and incentive mechanism for village officials， smooth the promotion channels， and form a management model with “both liberality and strictness”.
