The assessment of PV devices is a key issue,as the commercial value of a PV cell or module is directly linked to its maximum power value (Pmax) measured under standard conditions.To determine this value,a calibrated solar simulator is used at the end of each production line to test any single device.The measurement accuracy and reliability of such equipment is thus of prime importance,as are the QA process and testing environment which will also contribute to the final uncertainty.The advantages of a reliable measurement for manufacturers are that a) they will sell their production at therightprice b) their profitability will be determined by this reliability.For the final customers or investors a reliable measurement will ensure that they really get the performance they have paid for from the manufacturer.This presentation will define and present the importance of accuracy and precision for PV measurement,and relate this to the impact that thecostof measurement uncertainty has for a PV producer as well as for its customer.It will particularly highlight the key points each PV producer should be aware of while assessing a production,as well as the ways to reduce the PV measurement uncertainty.A reliable PV performance measurement is a contributing factor in enabling the industry to reduce costs and work towards grid parity.Our goal is to make PV producers as well as a wider community in the industry aware of the latest technological developments in the field and their impact on the performance measurement.

自"十月革命"以来,落后国家实现经济发展就是社会主义经济理论的中心议题。同时,由于很多二战后实现民族独立的国家也主动吸收和借鉴马克思主义经济理论指导经济发展,从20世纪中期以来,经济发展理论与社会主义政治经济学就形成了先天共生性,马克思主义经济发展思想在发展中国家迅速开花结果。伴随着经济社会的发展,马克思主义经济发展思想的研究议题逐步转变,尤其是中国改革开放后的经济社会发展成就,推动马克思主义经济发展思想逐步从"为什么不能发展"转向"如何实现发展",习近平新时代中国特色社会主义经济思想的形成则标志着中国社

20世纪70年代以来,一些西方发达国家进入了“问题时代”,增长乏力与不平等日益加剧成为其典型症候。“问题时代”固然与新自由主义的盛行有关,但其时间也恰好与第五次技术革命浪潮同步。第五次技术革命浪潮与前四次技术革命浪潮“绩效”的明显差异,意味着新熊彼特学派传统的技术—经济范式理论不足以解释技术革命浪潮效能释放过程中的制度性障碍,单一的制度视角或技术视角都无助于解释“问题时代”的成因。从历史唯物主义的立场出发,技术—经济范式的型构与展开必然受到社会—政治范式的影响,只有在技术—经济范式和社会—政治范式两者耦合
在《帝国主义是资本主义的最新阶段》(通俗的论述)中,列宁继承和运用马克思主义方法论,总结了《资本论》问世半个世纪以来世界资本主义的新变化,指出资本主义已经发展到一个新的阶段—帝国主义阶段。列宁运用历史和逻辑统一的方法,考察了资本主义垄断形成和发展的过程,把资本主义的新变化概括为五个基本特征,并在此基础上给帝国主义下了一个完整的科学定义。通过对帝国主义经济特征和历史地位的分析,列宁揭示了帝国主义时代经济政治发展不平衡的规律,指出帝国主义是无产阶级社会主义革命前夜。列宁的帝国主义理论科学说明了帝国主义战争的本
公开发布宏观经济前景的预测信息,并以此对未来的货币政策立场进行展望的前瞻性指引日益重要,它逐步成为中央银行新的货币政策工具。本文选取人民币在岸与离岸市场汇率数据,实证检验了中央银行前瞻性指引的有效性。研究发现:(1)中央银行的前瞻性指引可在合意方向上引导汇率,且平抑了汇率波动,总体上,前瞻性指引对在岸市场的效果弱于离岸市场;(2)在岸与离岸市场间存在双向的均值溢出和波动溢出效应,这进一步强化了前瞻性指引的效果;(3)不同货币政策取向的前瞻性指引在效果上具有显著差异,紧缩取向的前瞻性指引对在岸市场汇率的引导
