This paper establishes a post-evaluation system for civil aircraft science and technology innovation projects to evaluate the project’s objectives, implementation process, completion status, application of results, effectiveness, and impact. Through the post-evaluation, the scientific and technological plan and the degree of realization of the project objectives are timely evaluated, and the evaluation project's role in supplementing the technical shortcomings in this field and promoting model development. At the same time, it discovers the problems in the process of project implementation and results transformation, finds out the subjective and objective reasons for the success or failure of the project, summarizes experience and lessons, and makes recommendations for subsequent project decision-making and implementation management. To achieve the goal of dynamically optimizing scientific and technological development planning, continuously improving the management level of scientific and technological projects and scientific decision-making, and promoting the improvement of the technological innovation system.

This paper establishes a set of post evaluation system of civil aircraft science and technology innovation project, which evaluates the project objectives, implementation process, completion, application of results, benefit effect and impact. Through the post evaluation, we can timely evaluate the degree of realization of science and technology planning and project objectives, and evaluate the role of the project in complementing the technical shortcomings in this field and promoting model development. At the same time, it finds out the problems in the process of project implementation and achievement transformation, finds out the subjective and objective reasons for the success or failure of the project, summarizes the experience and lessons, and puts forward suggestions for the follow-up project decision-making and implementation management. To achieve the goal of dynamic optimization of science and technology development planning, constantly improve the level of science and technology project management and scientific decision-making, and promote the improvement of technology innovation system.<br>

In this paper, a set of post-evaluation system of civil aircraft science and technology innovation project is established, which evaluates the project objectives, implementation process, completion, application of achievements, benefit effect and impact. Through post-evaluation, the degree of realization of science and technology planning and project objectives is evaluated in time, and the role of the project in complementing technical shortcomings in this field and promoting model development is evaluated. At the same time, it finds out the problems in the process of project implementation and achievement transformation, finds out the subjective and objective reasons for the success or failure of the project, sums up the experience and lessons, and puts forward suggestions for the subsequent project decision-making and implementation management. Achieve the goal of dynamically optimizing the development plan of science and technology, continuously improving the management level of science and technology projects and scientific decision-making, and promoting the improvement of technological innovation system.
