Public policy is an important means to promote the realization of national macro-strategic goals, so the research to the relevant policies for the carbon neutral development of the civil aviation and further improvement are particularly important for the realization of the industrial and the national energy saving and emission reduction targets. The research adopts bibliometrics and content analysis method to sort out and analyze the relevant policies issued by the Civil Aviation Administration of China since the "11th Five-Year Plan" period. It is found that the current policies are characterized by a late starting time, a small number of policies and short length, and an absolute majority of guiding documents. And there are mainly the following four problems: the policy objectives of carbon neutral development are not clear; the macro of policy measures is overwhelming; the use of policy tools is insufficient and there is a lack of independent policy evaluation institution. Administrative departments in this industry should strengthen policy research, formulate specific carbon neutral policy objectives, make full use of various policy means, optimize the policy measures and the system and mechanism of policy evaluation, so as to further improve the system of policies and regulations and improve the quality of policies.
