Forecasting iron ore import and consumption of China using grey model optimized by particle swarm optimization algorithm

The iron and steel industry plays a fundamental role in a country's national economy, especially in developing countries. China is the largest iron ore consumption market in the world. However, because of limited domestic iron ore resources, a large proportion of iron ore is imported from other countries. Faced with the conflict between the iron ore supply shortage and the growing demand, it is necessary for the government to predict imports and total consumption. This paper develops a high-precision hybrid model based on grey prediction and rolling mechanism optimized by particle swarm optimization algorithm. We use the China Statistical Yearbook (1996–2011) as our database to test the efficiency and accuracy of the proposed method. According to the experimental results, the proposed new method clearly can improve the prediction accuracy of the original grey model. Future projections have also been done for iron ore imports and total consumption in China in the next five years.     

The ‘new’ economics of iron and steel

The author commences his analysis of the iron and steel industry by examining the historical background of the industry, and discusses its importance for the world economy. He examines the implications for the world industry of the successful development of the steel industry in Japan, and traces the evolution of a commodity cartel in the iron ore market, analysing the price levels of the commodity in the ‘free’ and ‘controlled’ markets. Following a discussion of the role of energy and coking coal supplies in the industry, the author examines the evolution of this industry in the less developed countries, with particular reference to the role of technology in the industry's development. He concludes that there have been important structural changes in the world industry, embraced by the concept of ‘partial demise’.     

Commodity booms and their impacts on the Western Australian economy: The iron ore case

Western Australia is a resource-rich province. Since the 1890s, resources booms have played a key role in the development of the state's economy. In the last few years, Western Australia's resources industry has continued to enjoy exceptional conditions created by strong international demand for commodities. This paper aims to examine the likely impact of this commodity boom in the iron ore sector on the Western Australian economy, using a general equilibrium approach. The modeling results indicate that the Western Australian economy will benefit from the expansion in iron ore exports and investment in terms of rising consumption and employment, although at the industry level there will be losers as well as winners.

Mitigation paths for Chinese iron and steel industry to tackle global climate change

Based on a recognition of the essence of climate change and the pressure on China to reduce its greenhouse gas (GHG) emissions, this paper interprets the important role that the Chinese iron and steel industry may play in managing emissions. Through an investigation of the key sources of GHG emissions in the Chinese iron and steel industry, a comparison of the current Chinese and international situations, and a survey of the technology and methods available for reducing GHG emissions, and their application in China, the authors analyze the major issues currently faced by the Chinese iron and steel industry, and propose the following four approaches through which the industry might reduce its GHG emissions: (1) encouragement of clean development mechanism (CDM) projects, mainly involving secondary energy reuse, to provide capital and technology for GHG reduction activities in China; (2) stimulation of the social responsibility-based voluntary carbon market (VCM) to increase the long-term benefits for the Chinese iron and steel industry from emission reductions; (3) undertaking of strict energy auditing to help enterprises establish appropriate emission reduction targets and formulate reasonable plans; (4) promotion of emission reduction-oriented investment within the industry to obtain profits from project operation, while at the same time gaining extra compensation for emission reductions. More specifically, the design of each of these approaches should take into consideration the related economic factors and incentive mechanisms.     

JAMAICA - A CASE STUDY OF ENERGY PLANNING

The analysis shows the impact of the 'New International Energy Order' on Jamaica, a developing country almost totally dependent on imported oil for satisfying national energy demand. The energy supply/demand situation between 1961 and 1976 and the structure of energy consumption by major sectors of the economy are discussed. The high income elasticity of commercial energy demand and the increase in the energy intensity of the economy is directly related to expansion of the alumina industry. The structural problems of decoupling GDP and energy growth are indicated. In particular, the impact of the 'New Energy Order' on the development prospects of major bauxite/alumina producing countries which are deficient in indigenous primary energy resources is assessed. Finally, the indigenous resource base is outlined and the major elements of the five-year (1978–1982) national energy plan summarized.

低碳经济背景下云南矿业可持续发展对策研究

低碳经济是以＂低能耗、低污染、低排放＂为主要特征的一种经济发展模式。对矿业而论,低碳型矿业是今后发展的必然趋势,但目前云南矿业是＂高消耗、高排放、低利用＂的粗放型发展模式。基于云南矿业的特点及制约因素的分析,提出其可持续发展对策,包括寻求最优开采率、发展矿产资源的深加工、进行企业结构调整、增加集约程度和矿产资源多元化利用、促进废物资源化等。其中,特别要关注尾矿的资源化利用、矿山生态环境的植物修复和煤炭资源的清洁生产。
