主　　题：Iron and steel Iron flow Value chain Statistical entropy Steel scrap 

摘      要：The iron and steel industry in China has experienced vast changes over the past thirty *** have a precise knowledge of the circumstances behind its evolution,it is essential to perform an iron flow ***,iron flow analysis for the years 1990-2015 was ***,the iron natural resource efficiency,Chinese steel scrap index,and Chinese iron ore support ratio which can reflect the running status of China s iron and steel industry for these six years(1990,1995,2000,2005,2010,and 2015)were analyzed;thereafter,value chain and statistical entropy analyses were conducted based on the iron flow analysis,and some interesting results were *** and conclusions based on the results along with the recommendations for the China s iron and industry were proposed.
