查询词典 characteristic

The economics methodology has formed a whole battery of analytical framework and tool under the influence of scientific philosophy, which is characterized by logic positivism, negativism and historical materialism. The fundamental characteristics of the economics methodology are based on the axiomatization positive logic deductive method, which assumes the rational human being as its hypothetic premise. The most remarkable characteristic of the economics methodology is the general application of mathematics in economics and it is developing forward to the more accurate and magnificent system.
