Just add milk: a productivity analysis of the revolutionary changes in nineteenth‐century Danish dairying

The late nineteenth‐century Danish agricultural revolution saw the modernization and growth of the dairy industry. Denmark rapidly caught up with the leading economies, and Danish dairying led the world in terms of productivity. Uniquely in a world perspective, high quality micro‐level data exist documenting this episode. These allow the use of the tool of modern agricultural economists, stochastic frontier analysis, to estimate production functions for milk and thus find the determinants of these productivity and efficiency advances. This article identifies the contribution of modernization through specific new technologies and practices.     

ATM网络上的LAN仿真技术

<正> 如按成员国的经济发展水平划分,战后的区域经济一体化可分为发达国家区域经济一体化和发展中国家区域经济一体化。就一体化的成果而言,无论从预定目标的实现程度、实施步骤和进展,还是从一体化所达到的层次,发达国家区域经济一体化明显好于发展中国家。其中有颇多经验和教训值得总结。     

Network development in international project marketing and the impact of external facilitation

This article reports on an experiment in external facilitation of international project marketing activity. The case involved a large, World Bank funded project in China aimed at upgrading grain storage and handling facilities. An organization was established in Australia to bring together and support efforts by Australian firms to win a share of this project. Network-building, at a number of levels both in China and Australia, emerged from the qualitative study as a critical factor in effective project marketing. External facilitation played a positive role in the network-building process.     

国际政治经济学中的跨大西洋分歧

自20世纪70年代国际政治经济学产生以来,呈现出不同国家和地区的研究特点与学术传统。如同国际关系学科一样,美国学派在国际政治经济学研究中占据着主导地位,英国学派则处于半边缘状态。笔者首先分别界定英国学派与美国学派,然后从知识传统、方法论、议题设置等维度诠释二者间存在的差异,进而从历史背景、学术传统以及学术训练等方面解释英美学派间的差异,并且考察英美学派间目前的交流状态及其对话的必要。由于国际政治经济学并不是由方法论所确定的,而是由共同的研究主题以及核心概念所界定,因而英美学派有必要进行切实的对话以构建一个真正的全球性国际政治经济学科。     

Aid and Public Finance: A Missing Link?

The present consensus in the literature is that foreign aid does not have the desired positive effects on economic development. This is due in great part to poorly performing public institutions in recipient countries. In order to understand better the causes of this undesirable phenomenon, we examine the relationship between multilateral foreign aid flows and recipient countries’ public finance systems. We construct a new indicator to assess the quality of public finance, the Public Finance Institutions Quality (PFIQ) Index. For our panel of 86 countries, we find that multilateral aid flows have a negative impact on recipient country PFIQ score, whereas exogenous improvements in public finance seem to attract more aid. These results provide insight into the “black box” of governance: failure to turn aid receipts into desired results seems partly attributable to multilateral aid, in its present form, not being suited to improving a country’s public finance institutions. However, international donor organisations do seem to reward exogenous improvements in quality and reliability of public finance systems.     

从海外出口加工区的现状看浦东出口加工区的开发

(一)1959年爱尔兰在香农镇(Shannon)的国际机场上设立的香农机场出口加工区是世界上最早从事出口加工活动的自由港区。但正式使用“出口加工区”名称并制订一套相应法规的,则是我国台湾地区于1966年建立的高雄出口加工区。爱尔兰香农出口加工区的建立,为发展中国家发展工业经济树立了样板。自此,这类新型的经济特区纷纷在名国涌现。到目前为止,世界上出口加工区总数已超过623个。     

三阶高频并联谐振变换器的相平面分析和设计

本文用相平面分析法分析和设计了一种电容耦合的并联谐振变换器。引入附加电容与传统的并联谐振变换器中的电感相串联,能获得更好的调节功能。本文利用平面轨迹图,给出了选择电路元件参数的设计依据。     

锁幅环路（MLL）及其应用

本文描述一个能使传递函数(TF)不管在任何输入频率时都能保持不变的新型控制环路——锁幅环路(MLL)。文中导出单一正弦信号时,输入频率与输出DC电压的线性关系,并讨论其可能应用。实验证明[1],MLL可执行锁相环路(PLL)的绝大部分功能。
