国内贸易的壁垒因素与边界效应——自然分割和政策壁垒

本文通过引入适合于我国省份层面的国内贸易边界效应模型,利用1997、2002、2005和2006年的相关样本,具体考察了影响我国国内贸易的两个层面壁垒因素。在控制了距离等自然壁垒变量后,实证得出了我国样本期的边界效应值为16.78,且1997-2002年和2002-2005年两个期间平均的省份边界效应具有上升的趋势(其中后个时期上升趋势明显走弱,显示边界效应的收敛趋势),而2005年之后则具有下降趋势;结果认为地方产业结构雷同对区际贸易具有阻碍作用,财政分权下的政府保护偏好是导致贸易壁垒的重要因素,省份的对外贸易对区际贸易具有替代效应,而经济结构和政策壁垒的总体边界效应达3.90。

汽车传动轴弯曲振动分析

商用车传动轴是商用车传动系统中的重要部件,因其振动频率低、刚度小,加上万向节附加力矩,使得传动轴的弯曲振动问题成为影响商用车振动和噪声的重要方面。本文对某商用车传动轴的弯曲振动问题进行了动力学仿真分析,对传动系统的隔振性能进行了分析,总结出中间支撑的刚度对整个转动系的隔振性能的影响规律,对于今后设计具有一定借鉴作用。

China's economic fluctuations and consumption smoothing: Is consumption more volatile than output in China?

This paper provides a fundamental study of China's consumption and output fluctuations. The most recent literature reports that, in the post-1978 period, detrended consumption is significantly more volatile than detrended output in China. This indicates the inability to impose consumption smoothing. However, in those previous studies, consumption of durables, which has some features of capital, as discussed in the real business cycle literature, was not separated from private consumption. This paper is the first to estimate consumer durables for China and their service values following the method introduced in Cooley and Prescott (1995). We adjust the consumption measure to make it consistent with the real business cycle literature, and find that consumption of durables is much more volatile than output, but non-durable consumption is less volatile than, and less correlated with, output that provides evidence that supports consumption smoothing in China.     

Thirty-two years of development of human resource management in China: Review and prospects

Focusing on the theoretical developments and practical applications of human resource management, this paper reviews the transition of human resource management in China from planned labor and personnel management to modern human resource management in three distinct time periods since China's reform and opening-up. Next the paper discusses the challenges of human resource management research and its practices from the perspectives of internationalization, corporate culture, and organizational innovation during China's economic transition. Finally, it presents the prospects and trends in the future development of human resource management in China.
