The North American Free Trade Agreement (NAFTA) took effect on January 1, 1994. The agreement is designed to reduce trade restrictions and enhance trade among Mexico, Canada, and the United States. The primary objective of this article is to examine and estimate the impact of NAFTA on the trade between Mexico and the United States. The data from 1989 to 1998 were used to estimate the overall trade as well as trade in three important products. The trade statistics were divided into two time periods: 1989-1993, before NAFTA, and 1994-1998, after NAFTA. The regression analysis and statistical t-test were employed to determine whether there were significant differences in the dollar volume of trade between the two time periods. The analysis of the data demonstrates that the trade between the United States and Mexico was significantly larger after NAFTA, which could not be attributed to other factors. However, the effects of other factors were analyzed. The success of the NAFTA model may have future policy implications in forging a Free Trade Area of the Americas (FTAA) in the near future.  相似文献

The purpose of this study was to investigate the bleaching efficiency of activated sodium perborate at low washing temperatures and the resulting energy saving. The comparison of the washing efficiency of basic and activated detergent was based on practical washing tests. The types of dirt used were coffee, fruit juice, tea, blood and a soot-oil mixture. The washing temperatures were 50, 60, 70 and 80°C. The cleanness of the washing was determined by a whiteness measurement. The consumption of electrical energy was measured with a kWh-meter. The higher the temperature, the more effectively all the types of dirt were removed from the textiles. With activated detergent a cleanness was obtained at 50°C and 60°C that was almost as good as with basic detergent at 80°C. The coloured types of dirt washed out more easily than blood or the soot and oil mixture. An average saving of 20% in the consumption of energy was obtained when the washing temperature was lowered by 10°C. With activated detergent, 45% of the energy consumed using basic detergent was saved with no reduction in the final cleanness.  相似文献

To examine U.S. multinational corporations, this research utilizes a multivariate model to differentiate among IHRM practices and their impact on U.S. expatriate performance. Questionnaires sent to 481 corporations combined with an analysis of the six independent variables, including selection criteria, cross-cultural training, and inability of spouses to adjust help us to understand U.S. expatriate rates of success and failure in Mexico. While, to a considerable degree, an IHRM model based on mainstream literature can predict U.S. expatriate success and failure rates, this research demonstrates the significant discrepancies that exist when comparing the results of the relationship of each variable individually.  相似文献

我国的精神损害赔偿制度是随着《民法通则》的公布实施而建立的一项新的民事法律制度,在保护民事主体合法权益方面发挥着重要的作用,但由于《民法通则》的规定过于原则,缺乏操作性,在实践中使得各个部门在各自的职权范围内制定的有关行政法规以及司法解释难以和谐统一,文章拟在精神损害赔偿的法律体系、适用范围、适用程序等基本问题方面进行分析并提出立法上的建议。  相似文献

The purpose of this study was to explain the effect of activated sodium perborate on cotton cloth. The comparison between the damage caused by basic and activated detergent was based on practical washing tests. The washing temperatures were 60°C and 90°C. Damage to the cotton was determined with a physical (tenacity) and a chemical (fluidity) method. Damage to the cotton increased as the temperature rose. Washing with basic detergent at 60°C did the least damage to the cotton. The activated detergent at 60°C damaged the cotton more strongly, but slightly less than the basic detergent at 90°C. Damage to cotton caused by washing can be determined more rapidly and more reliably with a chemical method than with a physical one.  相似文献

公共物品特性的动态性与供给模式探析   总被引:2,自引:0,他引:2  
张宪昌 《北方经贸》2006,(9):115-117
现有的公共物品理论较多的是从静态的角度考察公共物品的供给问题。因而,在解决公共物品供给的问题上过分强调单一解决方案的有效性。而现实中的公共物品属性往往因技术水平、制度、经济发展水平等因素呈现出属性的动态化特征,因而在公共物品的供给模式上也应采取动态化的模式与之相适应。  相似文献

引进外资是我国改革开放政策的一项重要内容,基于开放之初我国资金的极度稀缺,为了实现我国的社会经济政策,多而快地吸引外资,我国对外资实行了多种优惠政策,即对外资实行超国民待遇。超国民待遇涉及我国社会经济生活的方方面面,它起到了相当积极的、不可替代的作用;同时,我国长期执行的外资优惠政策对我国经济发展的诸多全局性不利影响也逐步显现。在中国加入TWO后过渡期的今天,我们有理由、有条件逐步取消超国民待遇,当然,在特定领域仍需保持适度的超国民待遇。  相似文献

中国对外贸易增长方式转变的路径与策略   总被引:3,自引:0,他引:3  
近几年来,特别是加入世界贸易组织后,我国对外贸易取得了突飞猛进的发展,对我国经济持续高速的发展起了极其重要的推动作用。我国已经成为世界第三贸易大国。但我国还不是贸易强国。长期以来,我国外贸快速发展主要是依靠粗放型增长方式,这种方式日益显现出其不可持续性。实现从贸易大国到贸易强国的转变,关键在于转变外贸增长方式。文章就这一问题进行了一系列的思考。  相似文献
