Cost management has been the production of iron and steel enterprises control link , it is an important indicator to measure the effectiveness of iron and steel enterprises . Currently , the iron and steel enterprises facing economic globalization , the increasingly fierce market competition , the new operating environment for the rapid development of information technology , the joint merger between domestic and foreign enterprises , the formation of large enterprise groups , the trend makes international steel market, increasing competition intense , leading to the market price of getting closer to industry costs , profit margins are getting smaller and smaller . The iron and steel enterprises are facing serious challenges , reduce costs to become an important means and ways of the iron and steel enterprises to improve competitiveness . However , the iron and steel enterprises manufacturing enterprise , traditional manufacturing mode of iron and steel enterprises in the production process , cost a lot of energy , while releasing a large amount of waste gas , waste, and caused great damage to the environment , is not conducive to cost reduction and improving efficiency , so the steel industry , the need to transform its traditional manufacturing model , and take the road of sustainable development of green manufacturing . Green manufacturing model takes into account the factors in the iron and steel enterprises in the production process , focusing on the conservation of resources , protect the environment , improve labor productivity . Therefore , how green manufacturing of the steel industry , the cost-benefit study has important theoretical and practical significance . The sustainable development , green manufacturing , environmental protection, research background, the steel industry, the implementation of cost-effective green manufacturing research . First introduced the composition of the steel industry connotation of green manufacturing and cost-effective ; followed by building evaluation system and model of green manufacturing cost-effective indicators of the steel industry ; Finally after the analysis of the case studies to prove the need for the steel industry, the implementation of green manufacturing , as iron and steel enterprises in the production and management practices to provide guidance , makes iron and steel enterprises to pay more attention to all aspects of production operations that may affect the cost-effective , and thus help enterprises to reduce costs , and provide high efficiency and environmental protection .
