语言交流连贯的文化语境因素

语言是交际的工具,人们使用语言进行交流,总是在一定的环境中进行的,即语言交流离不开语境,并受语境的制约。语境是语言环境的简称。语言交流同样离不开文化语境,文化语境是语言交流连贯性的基础,在语言交流中起着重要作用,因此不同民族在语言交流过程中必须注重文化语境因素,才能保证其交流的顺利进行。     

Does global liquidity drive commodity prices?

This paper tackles the question of whether a cross-sectional perspective on monetary policy is capable of explaining movements in global commodity prices. In this vein, we contribute to the rich literature on global liquidity in two different ways: on the one hand, to achieve a global series in terms of common monetary policy shocks, we propose a distinction between common and idiosyncratic factors across economies, as proposed by Bai and Ng (2004). Our second innovation stems from the consideration of a Markov-switching vector error correction model when analyzing time-varying short-run dynamics. Having identified the long-run structure which includes a proportional relationship between commodity prices and global liquidity in the first step, our results indeed show that the impact of a global liquidity measure on different commodity prices is significant and varies over time. One regime approximately accounts for times where commodity prices significantly adjust to disequilibria, while the second regime is characterized by either a weak or no commodity price adjustment. The fact that global liquidity also reacts to disequilibria in a specific regime demonstrates the two-way causality between monetary policy and commodity prices.     

Predicting bankruptcy using the discrete-time semiparametric hazard model

The usual bankruptcy prediction models are based on single-period data from firms. These models ignore the fact that the characteristics of firms change through time, and thus they may suffer from a loss of predictive power. In recent years, a discrete-time parametric hazard model has been proposed for bankruptcy prediction using panel data from firms. This model has been demonstrated by many examples to be more powerful than the traditional models. In this paper, we propose an extension of this approach allowing for a more flexible choice of hazard function. The new method does not require the assumption of a parametric model for the hazard function. In addition, it also provides a tool for checking the adequacy of the parametric model, if necessary. We use real panel datasets to illustrate the proposed method. The empirical results confirm that the new model compares favorably with the well-known discrete-time parametric hazard model.

Utilizing Printed Media to Understand Desired Leadership Attributes in the People's Republic of China

Using news media as a reliable source, we content analyzed stories on business leaders in two major official Chinese newspapers in three different time periods over the past 20 years. Results show that the reform has brought an increase in stories of business leaders, and in coverage of the desirable leadership attributes relating to Confucian virtues, communist ideologies, and modern management philophies. The results suggest that, by publicizing and adorning specific leaders in both government and business sectors in the official media, the government reinforces the traditional values that are consistent with communist ideologies, and at the same time, it also introduces Western management values to suit the current needs of the society. The results of our study echo the findings of empirical studies on Chinese values that used data collected using other methods. We therefore encourage future research to use the printed media as a potentially valuable source of data for tracking changes in social phenomena in a society over time.     

经济转型下的外商直接投资、国内资本与经济增长——基于中国时间序列数据的计量检验与实证分析

经济转型背景下,中国经济持续增长的一个重要原因是引入外商直接投资。本文对1985年-2010年中国外商直接投资、国内投资与经济增长的总量时间序列数据进行了实证分析。结果表明:FDI与国内资本对我国的经济增长的影响显著,都是GDP的格兰杰原因,与经济增长存在长期均衡关系;但FDI对经济增长的影响小于国内资本,并且FDI与国内资本还存在相互挤入效应。
