Headhunting is an important channel to allocate professional talents, and employee turnover has always been a key topic for the company and human resources researchers. Based on the analyses of the primary data of human resource service companies, this paper uses game theory to view the resignation of middle-section employees from the perspective of a headhunter, and the results show that the turnover is mainly about the increase in salary; the men employees tend to get more income than the female; the tendency of employees to seek cross-region configuration and cross-professional and cross-industry configuration affects the headhunting configuration pattern, and the alliance becomes a stable game decision in the simulated three-way game. Finally, the corresponding suggestions are put forward to provide a new perspective for promoting the allocation of human resources in China.
