The Grey Relational Analysis and Development Study of the Countrywide Agricultural Machinery Structure

摘要

Adopting relational analysis method of grey system, this paper carried out grey relational advantage analysis on the following aspects: the countrywide grain yield, the net income per capita of the countrywide farmer family, the countrywide farm machinery total power, the countrywide farm large and medium-sized tractors, the countrywide small-sized tractors and walking tractors, the countrywide big and middle farm implements for tractor, the countrywide agriculture irrigation and drainage power machinery. As a result , the development of the countrywide farm irrigation and drainage power machinery had the great effect on the countrywide grain yield, while the countrywide small-sized tractors and walking tractors took the first place to net income per capita of the countrywide farmer family. This paper provided reference evidence for studying the developing farm machinery structure.
