Crowding-out effect of coal industry investment in coal mining area: taking Shanxi province in China as a case

The rapid development of coal industry in Shanxi province in China has important effects on its economic development. A large amount of money has been invested into the coal industry and other related industries during the recent years. However, research on the investment effect of Shanxi’s coal industry was rare. In order to analyze the investment effect of coal industry, based on the crowding-out effect model, cointegration test, and the data available in Shanxi Statistical Yearbooks, this paper calculates the effect between coal industry investment and other 17 industry investment. The results show that the investment of coal industry produces crowding-out effect on food industry, building materials industry, and machinery industry. Increasing 1% of the coal industry investment can reduce 0.25% of the food industry investment, or 0.6% of building materials industry investment, or 0.52% of the machinery industry investment, which implies that Shanxi province should adjust coal industrial structure, promote the balance development of coal industry and other industries, so as to promote its economic growth.

The role of multiple regression and exploratory data analysis in the development of leukemia incidence risk models for comparison of radionuclide air stack emissions from nuclear and coal power industries

Risks associated with power generation must be identified to make intelligent choices between alternate power technologies. Radionuclide air stack emissions for a single coal plant and a single nuclear plant are used to compute the single plant leukemia incidence risk and total industry leukemia incidence risk. Leukemia incidence is the response variable as a function of radionuclide bone dose for the six proposed dose response curves considered. During normal operation a coal plant has higher radionuclide emissions than a nuclear plant and the coal industry has a higher leukaemia incidence risk than the nuclear industry, unless a nuclear accident occurs. Variation of nuclear accident size allows quantification of the impact of accidents on the total industry leukemia incidence risk comparison. The leukemia incidence risk is quantified as the number of accidents of a given size for the nuclear industry leukemia incidence risk to equal the coal industry leukemia incidence risk. The general linear model is used to develop equations that relate the accident frequency required for equal industry risks to the magnitude of the nuclear emission. Exploratory data analysis revealed that the relationship between the natural log of accident number versus the natural log of accident size is linear.     

Sustainable development and planning of coal industry under uncertainty using system dynamic and stochastic programming

We select a city that is one of the ten major coal bases in China and analyse the prospective development of the coal industry in this region. We introduce Stochastic Programming (SP) to the coal industry to manage uncertainties complicating the accurate prediction of the industry's development. First, we establish a coal industry system in the region and analyse this system. Second, we set up a System Dynamic-Stochastic Programming (SD-SP) model based on the coal industry in the region. Third, we set up the SD-SP model with sensitivity analysis to the coal industry. Finally, we complete the simulation by importing optimum parameters and contrasting the optimisation scheme with the current programming scheme.

Economic analysis of environmental problems in textile dyeing units: a case study from Ranaghat, West Bengal

The dye and dye intermediaries industry is an important segment of the chemical industry that provides inputs to a large number of industries. Currently, the Indian dyestuff industry is in the midst of a major restructuring and consolidation phase. With the emphasis on product innovation, rebuilding and environmental friendliness, this industry is increasingly moving towards greater customer orientation. Given the dynamic nature of the dyestuff industry in India and its tremendous potential, this study aims to conduct an economic analysis of the industry, with specific reference to its inherent environmental problems. The scope of the study was limited to a study of some units in Ranaghat, a town in the Nadia district of West Bengal. The potential environmental problems and the health hazards arising as results of dyes and dye production have been investigated. A case study of a dyeing unit in Ranaghat is presented, highlighting the negative impact on the water quality of its adjoining river, followed by some suggestions on ways of handling the pollution problem. A cost–benefit analysis of a dyeing unit in Ganganagar, and application of the results to the dyeing industry in Ranaghat, is also reported. The study also suggests some policies for consideration.     

Hazardous Waste Minimization: Part V Waste Minimization in the Petroleum Industry

The extractive nature of the petroleum industry sets it apart from other industries in many respects. The nature of this industry places it at somewhat of a disadvantage to other industries when attempts are made to foster waste minimization practices and programs. However, this is no excuse for the industry to not further vigorously pursue minimizing waste. This paper describes the petroleum industry and the products it makes along with their associated waste streams. The industry’s commitment to waste minimization is described with examples of specific minimization projects provided. Although the opportunities for minimization are limited, the economic incentives for reducing waste disposal costs, not to mention long term liability from improper disposal practices, has put the petroleum industry on the road to waste minimization.

Sea Grant's role: sharing with the community the goal of fostering ecologically-sound, and economically-viable, aquaculture

US aquaculture is one of the fastest growing segments of US agriculture; however, as aquaculture expands, a number of environmental, regulatory, and socioeconomic concerns threaten to constrain further development of the industry. This presents unique challenges to the Sea Grant network. Although Sea Grant encourages the commercial development of aquaculture, it must work with local communities to promote the goal of fostering ecologically-sound and economically-viable aquaculture in the USA. Sea Grant supports aquaculture through an integrated method of research, education and extension. Both National and State Sea Grant Programs support competitive research programs. State Sea Grant programs also employ a number of extension specialists who work directly with the aquaculture industry and various other stakeholders including industry associations, regulatory agencies, researchers, educators, and the general public. These specialists facilitate communication among stakeholders, and offer technology transfer, technical assistance, and educational programs to further the development of the industry in their respective States. Extension specialists communicate industry issues, research needs, and challenges back to the Sea Grant network. Sea Grant, through its research, education, and extension programs, has made significant progress in identifying and solving key problems impeding the expansion of USA.
