Study On The Circular Economic Efficiency Of Iron And Steel Industry In China

In the whole manufacturing industry of the national economy,the iron and steel industry is in the middle.The iron and steel industry is the pillar industry of national economy,it's development is the most important criteria of measuring the country's industrial modernization degree.Under the "new normal",our country's economic growth is more stable,economic structure optimizes and upgrades.On the time,put forward higher request to our country's iron and steel industry.With the implementing of the new Environmental Protection Law,there are higher standard for pollutant emission and green production,it will inevitably raise the environmental protection cost of our country's iron and steel industry.Chinese iron and steel industry is facing challenges of excess production capacity,lower average profit,higher resource consumption,more serious environmental pollution,lower resource circular utilization rate.One of the most effective ways to solve the series of problems is to develop circular economy.Chinese iron and steel industry's development stands still.Big but not strong is the characteristic of Chinese iron and steel industry.That is a plain truth.Circular economic of iron and steel industry is the important foundation of the strategy of sustainable development.Chinese iron and steel industry,only by developing circular economic,gain a firm foothold in international market.Circular economic efficiency is used to measure the level of the sustainable development of iron and steel industry,reflects the degree of the development of steel industry circulation economy,and conforms to the concept of sustainable development for steel industry.The text applies efficiency to measure the developmental level of circular economic of iron and steel industry.First,definite the concepts of iron and steel industry,circular economic,efficiency,put forward circular economic efficiency of iron and steel industry.Then,the object of study is the country's 30 provinces and cities get rid of Xizang.The time quantum of study is from 2004 to 2013.Apply DEA to analyze Chinese circular economic efficiency of iron and steel industry from static analysis and dynamic analysis.Next,apply TOBIT to research factors influencing Chinese circular economic efficiency of iron and steel industry.Finally,raise policy suggestions to enhance circular economic efficiency of iron and steel industry.The text is made of five sections.The first section introduces research,purpose,domestic and international review,thought,menthods and technical route of research and main innovations.It's the overall grasp.The second part elaborate relative theory and methods of circular economic efficiency of iron and steel industry.After definite the concepts of circular economic,circular economic efficiency,circular economic of iron and steel industry,circular economic efficiency of iron and steel industry,introduce the calculating methods of circular economic efficiency.The third part is empirical analysis of circular economic efficiency of iron and steel industry of china.Select of indicators of reacting effectively circular economic of iron and steel industry,then illustrate source and process of data,establish model of calculating circular economic efficiency of iron and steel industry.Based on the DEA-Malmquist evaluation model,combining with the actual situation,calculate circular economic efficiency of iron and steel industry of china,detailed analysis circular economic efficiency of iron and steel industry of china from static and dynamic analysis.The fourth part is influence factor analysis of circular economic efficiency of iron and steel industry of china.The fifth part is research conclusions and policy suggestion.Combining the background,calculations of assessing results and influence factor,raise policy suggestions to enhance circular economic efficiency of iron and steel industry,in order to provide some contribution to the development of steel industry of China.By means of the analysis of circular economic efficiency of iron and steel industry,some important conclusion as follows:Although there are some small rises of overall circular economic efficiency of iron and steel industry,efficiency loss is existing.The level of development has a large gap between the areas.Only Tianjin,Shanghai,Zhejiang.Jiangsu,Guangdong have been or near the level of circular economic efficiency valid,the rest of the provinces have a certain distance with the best state.In addition,from the perspective of regional circular economy efficiency change analysis,found that various areas to enhance the circular economy efficiency of iron and steel industry is mainly rely on technological progress.On the analysis of regional distribution,Chongqing's circular economy efficiency of iron and steel industry is the fastest.Henan's circular economy efficiency of iron and steel industry and Heilongjiang's circular economy efficiency of iron and steel industry is the slowest.Though the analysis of the factors that influence circular economy efficiency of iron and steel industry found that:The effects of various factors on circular economy efficiency of iron and steel industry have big difference.There are positive correlation relationship between regional technology change,economic development level,industrial concentration,which technology changes is significant.The proportion of state-owned enterprises and the proportion of coal energy consumption has certain negative influence for the circular economy efficiency of iron and steel industry.Therefore,there are some advises for our country's iron and steel industry developing circular economic.First,Establish evaluation standard of the circular economic efficiency of iron and steel industry.Second,Introduce advanced technology,to increase the utilization ratio of the sources of iron and steel industry.Third,Close down backward production facilities,improve the quality of products.Fourth,Improve the quality of annexation and reorganization,to improve the industrial concentration.Fifth,Optimize distribution of iron and steel industry,to promote coordinated development of industry.Sixth,Increase support private iron and steel enterprise,to realize the market competition mechanism of iron and steel industry.
