In this study,an inventory analysis approach was used to investigate the intensity of agricultural non-point source pollution(ANSP)and its spatial convergence at national and provincial levels in China from 1999 to *** this basis,spatial factors affecting ANSP were explored by constructing a spatial econometric *** results indicate that:1)The intensity of China's ANSP emission showed an overall upward trend and an obvious spatial difference,with the values being high in the eastern and central regions and relatively low in the western region.2)Significant spatial agglomeration was shown in China's ANSP intensity,and the agglomeration effect was increasing gradually.3)In the convergence analysis,a spatial lag model was found applicable for interpretation of the ANSP intensity,with the convergence rate being accelerated after considering the spatial factors but slower than that of regional economic growth.4)The spatial factors affecting the ANSP intensity are shown to be reduced by improving agricultural infrastructure investment,labor-force quality,and crop production ratio,while the expansion of agricultural economy scale and precipitation and runoff have positive impact on ANSP in the study ***,agricultural research and development(R&D)investment showed no direct significant effect on the ANSP ***,improving the quality of the labor force would significantly reduce the ANSP intensity in the surrounding areas,while the precipitation and runoff would significantly increase the pollution of neighboring *** research has laid a theoretical basis for formulation and optimization of ANSP prevention strategies in China and related regions.

Chinese Business Review 2014年第2期13卷 94-100页

作者： Marcelo Real Prado Georges Kaskantzis Neto Federal Technological University of Parana--UTFPR Curitiba-PR Brazil Federal University of Parana-UFPR Curitiba-PR Brazil

The knowledge of a product＇s life cycle is the first step on the search of sustainable development. The life cycle assessment （LCA） is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the ＂returns＂ to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks： glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.

Based on the literature research and related concepts of inland river container freight supply chain, this paper analyzes the influence of inland river container freight supply chain under the reduced vessel speed. Firstly, this paper describes the research problems and makes assumptions. Then a two-echelon inventory management model based on controllable lead time and stable demand is presented and the impact of slow steaming on inland river container freight supply chain is quantitatively analyzed. Finally, the impact of slow steaming on the inventory cost and inventory strategy of the shipper and consignee in the container freight supply chain is studied and some feasible suggestions are given.
