中国出口贸易的技术结构及其变迁:1980-2003 总被引:43,自引:0,他引:43
本文旨在构建一套测度出口贸易技术结构的方法,并在SITC三位码分类水平下,从国际比较的角度,分析改革开放以来中国出口贸易的技术结构及其变迁。第一,本文建立了测度产品技术含量的一个指标,进而提出一套分析经济体出口贸易的技术结构的新方法;第二,利用本文提出的分析工具,通过国际比较,从多个方面分析了1980—2003年中国出口贸易的技术结构,结果表明:改革开放以来,中国出口贸易的整体水平得到了很大提高,但仅表现出微弱的向世界水平收敛的趋势;中国出口贸易的技术结构高度没有显著提高,但在不同时期表现出不同的趋势;中国出口贸易的技术结构分布发生了与众不同的重大变化。 相似文献

This note shows that if the space of events is sufficiently rich and the subjective probability function of each individual
is non-atomic, then there is a σ-algebra of events over which everyone will have the same probability function, and moreover,
the range of this common probability is the entire unit interval.

This paper studies the optimal combination of debt and dividend commitmentsin an agency model of the firm. Financial policy is relevant because ex-post information asymmetry requires managerial rewards to depend on the ability to meet financial commitments. If perquisite or inside information problems exist in isolation, debt-based incentives as assumed in previous studies result endogenously. If the problems exist simultaneously, dividends can be optimal even when they appear excessively costly as a signal and unduly lenient as a disciplining device. The reason is that the set of dynamically consistent rewards increases when debt commitments are augmented with dividend commitments, and a larger set of ex-post rewards is more valuable as ex-antedecisions become more complex. 相似文献

This study constitutes a contribution to the discussion about moral reasoning in business. Kohlberg’s (1971, in Cognitive Development and Epistemology (Academic Press, New York), 1976, in Moral Development and Behavior: Theory and Research and Social Issues (Holt, Rienhart and Winston, New York)) cognitive moral development (CMD) theory is one explanation of moral reasoning. One
unresolved debate on the topic of CMD is the charge that Kohlbergian-type CMD theory is gender biased. This research puts
forth the proposal that the issue may be elucidated by exposing an ambiguity in “gender” (Borna and White: 2003, Journal of Business Ethics
47, 89–99; Gentile: 1993, Psychological Science
4(2), 120–122; Unger: 1979, American Psychologist
34(11), 1085–1094). We use the Sociomoral Reflective Objective Measure (SROM) to measure CMD and the Bem Sex Role Inventory
(BSRI) to measure gender as a psychosocial concept, rather than as a biological classification. The results of our study indicate
that high femininity, measured as a psychosocial attribute, is associated with significantly lower Kohlbergian-type CMD scores
among business practitioners. Sex moderates the effect of gender on CMD, but only indirectly. Our research also reveals that
education plays a significant moderating role in the relationship between gender and moral reasoning. In addition, age has
a significant direct effect on CMD scores of business practitioners.

In this paper, we investigate spread options with counterparty risk in a jump-diffusion model. Due to the fact that there is no closed-form formula of spread options with counterparty risk, we obtain analytical expressions of lower and upper bounds by employing the measure-change technique. Finally, we numerically check the accuracy of the bounds and analyze the impacts of counterparty risk and jump risk on spread option prices. 相似文献
