Making a reasonable evaluation of comprehensive agricultural development projects is not only to guarantee high quality of project implementation, but also of practical significance to the enhancement of our country' s comprehensive agricultural production capacity. Being based on the present situation and characteristics of the project, this paper has raised the general thinking about the overall performance evaluation for the project and analyzed the dimension factors in the evaluation system.展开更多
