《土壤污染防治法》的实施表明我国对土壤污染治理工作的重视,防治土壤污染除了采用一般污染防治手段之外,必须在治理土壤污染过程中引入环境经济手段。本文以《土壤污染防治法》为基础,对土壤污染防治责任主体、政府在资金方面的主体责任、基金制度及财税金融政策等加以分析,在借鉴国外土壤污染防治经验的基础上,提出我国在土壤污染防治中环境经济手段的运用和实施措施。 相似文献

土壤环境作为食品安全的基础,以维护食品安全为目的。当前,我国土壤污染严重,其中尤以农药、化肥等有机物残留污染和重金属污染最为严重。当进入土壤中的有害物质数量超过土壤的自然本底含量及土壤自净能力的限度时,将会使得其在农作物内得以残留或积累,污染不断积累严重破坏土壤结构,进而使得土壤小动物和微生物减少或死亡,最终增加农作物体内的毒物残留量,严重影响到食品质量安全。为此,应构建良好的土壤生态环境,加强土壤污染防治。而当前土壤污染防治中最大的制约因素是存在制度性缺陷。因此,本文主要从构建防治土壤污染制度方向展开研究,并提出相应制度措施。 相似文献

In this paper, developments in human resource management in manufacturing in modern Britain based on a national sample are examined. The organization and role of human resource management, employee involvement, training and development, work practices and rewards are all targeted for an assessment of current practices. This is a prelude for a contrast between manufacturing and non-manufacturing. The conclusion is that the similarities between manufacturing and non-manufacturing substantially outweigh the differences. By inference, too, developments in human resource management practices are likely to reflect changes in the broader environment of businesses (and differences between companies) rather than being specific to the main industrial sectors. 相似文献

Abstract Data on crop production are assembled for four provinces—Punjab, Sindh, North-West Frontier Province and Balochistan—for the period from 1980/81 to 2005/06 to examine inter-provincial differences in productivity growth rates. Propositions are put forward and examined to explain the superior productivity performance of Punjabi crop producers over those in Sindh and North-West Frontier Province, and the unusual productivity trends in Balochistan. The major factors relate to economic infrastructure and human capital. The impact of agricultural research is difficult to discern, and further work is required to assess the lagged effects of research expenditures on TFP growth. Explication des déséquilibres interprovinciaux dans l'augmentation de la productivité dans la production de cultures au Pakistan RÉSUMÉ On a rassemblé des données pour les quatre provinces suivantes: Penjab, Sindh, Khyber-Pakhtunkhwa, et Baloutchistan, pour la période 1980/81 à 2005/06, afin d'examiner les différences interprovinciales dans les taux d'expansion de la productivité. On présente et on examine des hypothèses pour expliquer le rendement supérieur des producteurs du Penjab par rapport à ceux du Sindh et du Khyber-Pakhtunkhwa, ainsi que les tendances de productivité inhabituelles du Baloutchistan. Les principaux facteurs se rapportent à l'infrastructure économique et au capital humain. L'impact de la recherche sur l'agriculture est difficile à établir, et des travaux supplémentaires seront nécessaires pour évaluer les effets décalés des frais de recherche sur l'expansion du TFP. Explicación de la desigualdad inter-provincial en el crecimiento de la productividad de la producción de cultivos en Pakistán EXTRACTO Se recopilan datos sobre la producción de cultivos de cuatro provincias: Punjab, Sindh, Provincia de la Frontera Norte-Oeste y Balochistan, durante el período de 1980/81 a 2005/06, para examinar las diferencias inter-provinciales en los índices de crecimiento de la productividad. Se plantean y examinan propuestas para explicar el mayor rendimiento de la productividad de los productores de cultivos Punjabi con respecto a los de Sindh y la Provincia de la Frontera Norte-Oeste, y las inusuales tendencias de la productividad de Balochistan. Los factores principales se relacionan con la infraestructura económica y el capital humano. El impacto de la investigación agrícola es difícil de discernir, y se requiere más trabajo para evaluar los efectos retrasados de los gastos de investigación en el crecimiento TFP. 相似文献

西部外贸中小企业发展的战略选择 总被引:4,自引:0,他引:4
中小企业是西部地区外贸进出口的重要力量。据统计,2005年,西部地区中小企业的进出口额达156.03亿美元,占西部地区进出口总额的34.6%,同比增长37.5%,表现出强劲的发展势头,成为推动西部地区对外贸易发展的一支最具活力的力量。然而,与东部地区同类企业发展相比,由于受区域经济发展水平、思想观念、经营环境以及政策等多种因素的影响和制约,西部外贸中小企业的发展还明显滞后。 相似文献

Smith LS 《Hospital materiel management quarterly》1998,20(1):61-69
Materiel managers are faced with a shrinking world and changing work environment. The needs and expectations of the customer have shifted because of the increasing number of multicultural groups. These groups will continue to assert their right to culturally sensitive care. Materiel managers also need to learn to support and enhance the skills of a multicultural work force. One important tool for change will be technology. However, technology that brings the world closer together also creates new challenges for managers, who will have to deal with multicultural colleagues, buyers, sellers, and manufacturers of goods and services. 相似文献

Panel data based studies in econometrics use the analysis of covariance approach to control for various ‘individual effects’ by estimating coefficients from the ‘within’ dimension of the data. Often, however, the results are unsatisfactory, with ‘too low’ and insignificant coefficients. Errors of measurement in the independent variables whose relative importance gets magnified in the within dimension are then blamed for this outcome.Errors-in-variables models have not been used widely, in part because they seem to require extraneous information to be identified. We show how a variety of errors-in-variables models may be identifiable and estimable in panel data without the use of external instruments and apply it to a relatively simple but not uninteresting case: the estimation of ‘labor demand’ relationships, also known as the ‘short-run increasing returns to scale’ puzzle. 相似文献

This article presents an overview of mediation in industrial disputes, and examines the British experience of using this form of third-party intervention since the establishment of the Advisory, Conciliation and Arbitration Service in 1974. The Author concludes that there is scope for the development of mediation in dealing with particular types of industrial disputes. 相似文献
