The Brief Review of Evaluation Method  Data envelopment analysis, DEA has developed into a kind of non-parametric frontier efficiency analysis method on the basis of the relative efficiency evaluation by A.Charnes and W.W.Copper scholars etc. this method is often used in input and output system of the production and living for management, decision-making and efficiency and benefit evaluation, etc, at present which has become a widely used and effective analysis tool in the field of management science and system engineering.
Middle and lower reaches of industries was worst affected by it, such as textiles, metallurgy, paper making, building materials, machinery and electronics, chemicals and other industries, and then spread to energy and raw materials consisting mainly of upstream industries, such as coal, crude oil, iron ore, etc..
