The paper studies the distribution characteristics and determinants of job vacancies. The parameter estimation is based on the two-stage Tobit procedure. The main statistical results are as follows: There is a positive correlation between the hiring scale and job vacancy incidence, while there is a negative correlation between the qualification vacancy rate and the hiring scale. The higher the labor turnover rate in units, the higher the job vacancy incidences and the vacancy rates are. The 98.39% of institutions with prospects have labor needs, and 39.53% of units declining say they will hire new staff. After decomposing the Theil Index which reflects the gaps among vacancy rates, the differences among vacancy rates of different units are mainly from the inner causes of various groups, and the intergroup reasons are not main ones.
