这次会议讨论的是一个很重要的题目──国企转型与企业文化构建。我们现在对企业文化的认识,如果同10年前相比,可以说是跨越了一个世纪。当时感觉企业文化是个新鲜东西,并不知道它有多大用途,好像很时髦,多数人对它的认识还是狭窄的、浮面的。10年后的今天,经过理论界的探索研究,特别是经过企业界的创新实践,使得我们对企业文化的认识有了很大的发展。中外企业文化杂志社利用庆祝创刊10周年的机会,组织大家共同研讨国企转型与企业文化构建,这个题目选得非常好。当前,企业文化在中国的需求,很重要的一点就是与国企转型联系在了一起。企业文化… 相似文献

China' s foreign-oriented oil taxation system has, from the beginning, been based upon the positive experiences of other oil-producing countries and has incorporated common international practices. The system has been perfected over decades. It of fers more incentives than other oil-producing countries in the following four aspects: (1) Income tax has a "wide tax base and low tax rate"; (2) VAT levies a low tax rate on ma- 相似文献

A model of corporate ethics and social responsibility (CESR) was developed and empirically tested among Chinese business undergraduates in Hong Kong and Singapore. As predicted, it was found that CESR beliefs were negatively related to Machiavellianism and two Confucian concepts, guanxi (interpersonal connections) and mianzi (face). CESR beliefs were also lower among Hong Kong than Singaporean youths. The negative effects of guanxi, mianzi, and Machiavellianism were more pronounced for the Hong Kong than Singapore sample. Implications of these findings are discussed and directions for future research suggested. 相似文献

Applying jump-robust methods to estimating integrated volatility is in the mainstream of financial econometrics. However, little if any attention has been devoted to the construction of a jump-free estimator for integrated covariance that overlooks the well-documented manifestation of joint jumps. Joint jumps are contemporaneous within the day. Therefore, this study proposes a three-point approach that not only deals with estimating volatility, but also constructs a singular-jump-free and joint-jump-free covariance. Since the basic idea of the three-point covariance is based on conditional quantiles, we also provide two alternative procedures for finding approximated estimations in practical applications. Based on this approach, our empirical results confirm that singular jumps and joint jumps occur on the Taiwan Futures Exchange. 相似文献

In this study both aggregate and industry‐level foreign direct investment (FDI) data are employed to investigate the spatial dependence of FDI hosts. The analysis contributes to the existing literature by focusing on the heterogeneous spatial correlation of FDI in different industries. Using more comprehensive FDI data across multiple industries and multiple provinces in China from 1999 to 2007, the results show a significant spatial correlation among provinces. Aggregate FDI tends to be regional trade platform oriented indicating neighboring provinces become competitors for FDI. In contrast, results based on industry‐level provincial FDI show stronger support for vertical or complex vertical FDI. 相似文献

Under both the overconfidence and disposition biases, a positive relationship is predicted between prior returns and subsequent trading volume. However, theoretically the overconfidence and disposition effects have different implications on the relationships between the long- and short-position gains of traders and their subsequent buying and selling activities. We examine a unique dataset obtained from the Taiwan Futures Exchange which records all account-level trades and orders. Our data and methodology have the advantage of being able to empirically differentiate these two effects and we demonstrate that different types of traders exhibit different types and levels of behavioral biases. 相似文献

We find that an important programming error was made by Hobijn and Franses ( 2000 ) in conducting multivariate stationarity tests. The empirical results in their paper are subject to errors. Other studies that have used the coded algorithm of Hobijn and Franses are likely to suffer the same problem. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

建筑工程的质量问题已成为社会关注的焦点.一个工程质量的优劣,直接关系到群众的切身利益.作为整体工程骨架的钢筋混凝土,它存在于工程的各个部位,工程质量的优劣直接筑物的使用年限,以及人们的生命安全.因此要提高建筑工程的质量,首先要抓好结构工程质量,即抓好地基与基础部分和主体部分的工程质量.如果此部分的工程质量保证不了,即使地面、门窗、装饰、水暖、电工程搞得再好,也是徒劳的,也无法保证整个工程的安全.所以在建筑工程中钢筋混凝土质量的控制措施是摆在每一个建设者面前的重要课题,也是质量管理的重中之重. 相似文献
