Under the background of strategies of “Mass Entrepreneurship and Innovation”，featuring innovation-driven development and innovation-driven entrepreneurship，the personnel system of public institutions is facing policy restructuring，including further delegating the power of personnel management，reforming staffing management，supporting full-time entrepreneurial activities，strengthening talent incentives and innovating talent evaluation system. At the same time，there are still many obstacles to be overcome，including contradictions between autonomy of staffing and control the size of personnel supported by central budget，between canceling control of staffing and reinforcement of staffing management，between staffing regulations and full-time entrepreneurial activities，between income distribution incentives and the control of total income，and between scientific talent evaluation and its formalization. Therefore，the strategy of “Mass Entrepreneurship and Innovation” needs to be cautiously promoted. More efforts need to be done to ensure the autonomy of personnel management and to balance the relation between authorization and supervision.
