首先论述了现代管理决策理论对我国航空发动机研制发展的重要意义和科学决策的关键作用。通过国内外航空新机研制发展的成败实例，分析总结在决策与管理上的经验与教训，并进一步阐述了在决策航空发动机的研制发展时，必须从我国实际出发正确处理好几个关系。为了我国航空发动机更好、更快地发展，当务之急是实施决策科学化和民主化。最后对我国新机研制发展科学决策提出了几点建议。

The significance of the theory of modem management and decision making to the research and development of aero-engines in China is discussed. Then by reviewing some successful and unsuccessful examples in and out of China of decision making in research and development of new aero-engines, experiences and lessons in decision making and management are analysed and summarized. It is further stated that several relationships should correctly be handled in connection with the practice in China in the process of research and development of Chinese aeroengines. For the better and faster development of Chinese aero-engines, to practise decision making in a scientific and democratic way will be the first important measure to be taken. At last suggestions for scientific decision making in research and development of Chinese new aeroengines are presented.
