在各类《统计学》教科书中,对数量指标和质量指标概念的解释不大一样,但基本的含义却是相同的。两者从概念上区别并不困难,也容易理解,但在对一些特殊问题的分析时,却不易把握,特别是在比较复杂的统计分析中,那就更不容易做出准确的判断了。怎样才能对数量指标和质量指标的应用做出科学的评价和分析。本文拟就这方面的问题做些初步探索。 相似文献

In recent papers, Moon and Choi (1998) and Hariga and Ben-Daya (1999)considered a continuous review inventory model with a mixture of backordersand lost sales in which the lead time, the order quantity, and the reorder pointare decision variables was studied. Moreover, they also develop a minimaxdistribution free procedure for the problem. While the demands of differentcustomers are not identical in the lead time, then we can't only use a singledistribution (such as Moon & Choi (1998) and Hariga & Ben-Daya (1999))to describe the demand of the lead time. Hence, we correct and extend the modelof Moon and Choi (1998) and Hariga and Ben-Daya (1999) by considering thelead time demand with the mixture of distributions. In addition, we also applythe minimax mixture of distributions free approach to the model by simultaneouslyoptimizing the order quantity, the reorder point, and the lead time to devise a practical procedure which can be used without specific information on demand distribution. 相似文献

货币理论是经济学中最富争论的理论之一。货币理论的基础也就是供求规律。对于其中的货币需求理论,从古至今有不少学者发表了不同的看法,形成了几种互不相同但彼此又有一定联系的学说。比较这些理论的异同,对于我们学习货币理论并制定和分析现实的货币政策具有重要的理论意义和实践价值。 相似文献

金融业在现代经济中发挥着极其重要的作用,而金融创新是金融业持续发展的源泉,人才又是金融创新的关键。文章首先运用GM(1,1)模型对我国2012年-2020年金融业人才需求量做了预测,随后根据2009年金融创新人才的占比,以金融业从业人员的平均增长速度作为金融创新人才需求量的平均增长速度推算出了2012年-2020年金融创新人才需求量的占比,最后根据金融业人才需求量和金融创新人才需求量的占比预测出了2012年-2020年金融创新人才需求量,并根据预测结果提出了相关的建议。 相似文献

This paper examines the existence and characteristics of pure-strategy Nash equilibria in oligopoly models in which firms simultaneously set prices and quantities. Existence of a pure-strategy equilibrium is proved for a class of price–quantity games. If the demand function is continuous, then the equilibrium outcome is similar to that of a price-only model. With discontinuous demand and limited spillover, there are rationing equilibria in which combined production falls short of market demand. Moreover, there might again be an equilibrium reflecting the outcome of a price game. Competition in price and quantity thus yields Bertrand outcomes under a variety of market conditions. 相似文献

Economists believe that economic fluctuations can be smoothed by stabilization mechanisms, such as price adjustment, embedded in the economy. While price adjustment can be seen as a stabilization mechanism, are there mechanisms that can destabilize an economy? We find that as early as 1939, Harrod discussed a destabilization mechanism, the firm's investment adjustment, illustrated in his knife-edge puzzle. We build a macro-dynamic model with investment and price as the core macroeconomic variables. Our analysis shows that the interaction between the stabilization mechanism (price adjustment) and the destabilization mechanism (investment adjustment) generates fluctuations and cycles. However, due to price stickiness, the price adjustment mechanism may not be enough to stabilize the economy. In this case, a government stabilization policy is necessary for further stabilization. As this paper also addresses the microfoundations of Keynesian quantity theory, including the choice of output and investment in optimization, it can be related to traditional Keynesian economics, with a new perspective to understand business cycles. 相似文献

计量体系包括标准的建设及以技术为手段的计量管理。标准是衡量质量高低的基本依据,各项标准的实施,又要以相应的计量检测和科学的计量管理为技术手段和管理基础。企业计量体系运行的成功与否,直接关系到产品质量结果的控制。经过陕西省质量技术监督初审和2次复查考核,2008年1月份,建标申请经考核合格后获得了授权,并于2月份,压力类强检仪表也获得了对内强检资质。长庆油田分公司第二采气厂计量体系的建设与运行步入正规化、运行基本实现了专业化。 相似文献
