Abstract

The invention discloses a public welfare railway judgment method which comprises the following steps of S1, qualitatively judging whether a railway has the public welfare or not by utilizing the definition and the basic characteristics of a public welfare railway; S2, further quantitatively identifying the specific type of the public welfare railway by utilizing a financial evaluation index and anational economy evaluation index; and S3, comprehensively evaluating the public welfare degree of the public welfare railway by applying the fuzzy mixed decision theory. According to the invention, the definition and the basic characteristics of the public welfare railways are comprehensively considered, the financial internal return rate and the economic internal return rate in the current railway economic evaluation system are considered, and the latest theory in the international comprehensive evaluation aspect is introduced to carry out the comprehensive evaluation on the public benefit degree, so that the problems that in the prior art, the expert qualitative analysis is still adopted to judge whether a railway has public benefit or not is subjectively, and the quantitative judgmenton the public benefit railway is difficult, are effectively solved, and the blank in the field of public benefit railway research is filled up.
