【Abstract】 The survey on the sinking employment and career development of agriculture-related doctoral graduates shows that the market segmentation of the academic labor market in China is obvious, and the career development of doctors is closely related to the level of working universities. Their career choices are jointly influenced by the human capital effect, signal effect and employment preference. The post-doctoral experience has become an important signal effect source. Graduates with no post-doctoral experience are more likely to choose sinking employment.
