国际垂直专业化、贸易分工模式与福利

在标准贸易理论框架下,通过引入垂直专业化和片段化生产,从理论上分析了国际垂直专业化对各参与国贸易分工模式的拓展及对国民和要素所有者福利的影响。研究结果表明,垂直专业化使一国比较优势由产品间深入到产品内部,进而使得各参与国贸易分工模式更为复杂,一国贸易模式可能会与该国原有的传统比较优势相悖;垂直专业化增进了世界福利,但在特定分工模式下可能会损害一国的福利,并且对于不同要素所有者福利的影响是不确定的。

水下高速气体射流的实验研究

本文对高速空气射流在受限约束下的动力学行为进行了实验研究。通过流动可视化揭示了高速空气射流在单筒和同心筒发射筒底部滞止、反转、而后向上绕经航行体或同心筒间隙向上喷入水中的演化过程。主要观察了单筒底部有无导流锥、同心筒三种间隙在不同压比和不同流量下的气水两相流态,并测量了航行体与发射筒的壁面压力分布。给出了航行体壁表面压力的动态变化规律,和沿轴向的分布规律。     

契约执行效率与垂直化结构

本文在LuigiPascali分析框架的基础上构建了一个两部门垄断竞争模型,考察不完全契约与垂直化结构的关系,并利用中国分地区分行业数据进行了检验。分析结果表明：契约执行效率的提高有利于垂直专业化分工;在契约要素密集度和物质资产专用性高的行业,契约执行效率与垂直一体化存在着明显的负向关系,在控制其他变量以及内生性问题后,这一结果仍然稳健;契约执行效率对人力资产专用性行业的治理结构影响不大。     

解析新货币经济学

20世纪80年代以后,新货币经济学的观点逐渐被人们所重视。新货币经济学主张将传统的统一于一种货币中的记账职能和交易职能相分离,来解决传统的“二分法”问题,并提出了“精密的物物交换体系”为基础的经济分析方法。同时认为如果取消法律限制,传统的货币将消失。新货币经济学对货币本质的认识和电子货币的发展提供了新的理论思路。     

New technology and the urban environment

Technology has always had an influence on the form of settlements, but only since the coming of Information Technology has it aroused much interest from academics and planners. The impact that IT is likely to have on urban areas is debated, some foreseeing decentralisation and the end of place, while others see evidence of the centralisation of control in a global economy. Other new technologies may also affect cities as new materials provide the opportunity for different styles of building. As we enter the 21st century, however, we do so with the largest stock of urban capital ever, much of which is ageing and in need of maintenance. Technology is part of a complex interrelationship of influences on urban areas and much of it will have to be retrofitted on to the pre-existing environment.

The relationship between employee performance management and civil servants’ turnover intentions: a test of the mediating roles of system satisfaction and affective commitment

In search of maximizing efficiency, public organizations found solace in the adoption of employee performance management (EPM) systems. While research supports that managing employees’ performance has favourable outcomes, it is still unclear why and under which conditions. Moreover, EPM systems might even create additional pressures and therefore increase turnover intentions and undermine public organization’s quest to maximize efficiency. We argue that when EPM systems are carried out consistently (i.e. internal consistency) and when they link civil servants’ individual goals to the organization’s strategic goals (i.e. vertical alignment), civil servants will be less likely to leave the organization. Hierarchical linear regression analysis shows that internal consistency relates to increased satisfaction with the EPM system and affective commitment to the organization. Vertical alignment relates to lower levels of turnover intentions. This relationship was mediated by EPM system satisfaction and affective commitment. These findings that contribute to our understanding of EPM systems can lead to favourable outcomes.
