宁波市上市公司盈利质量不高的原因与对策

盈利质量的不断改善和提高是企业可持续发展的根本。上市公司的主营业务利润比重与企业盈利质量存在正相关关系，即主营业务利润比重越大，上市公司的盈利质量越高，因此，提高盈利质量的关键就是要突出主业，壮大主业，不断提高主营业务利润比重，形成自己的核心盈利能力。     

倾斜摄影测量中影响模型精度的因素分析

目前,倾斜摄影测量作为一种新技术,经过不断的探索、应用和发展,已开始在测绘行业中大显身手,并取得了不小的成绩。通过三维模型进行的矢量数据采集,其矢量精度完全依赖于三维模型精度。论文以实践经验为基础,定性地分析了在航空摄影、像控测量、模型生产三阶段中,影响模型精度的因素,希望对三维模型的生产起到一定的指导作用。     

Joint outputs and real wage rates

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares.     

The Delphi method, impeachment and terrorism: Accuracies of short-range forecasts for volatile world events

Two experiments examined the effects of iterated polling and feedback on prediction accuracy for volatile world events using the Delphi paradigm. In both experiments, participants predicted rapidly changing geopolitical events. The first experiment occurred during the litigation surrounding the Clinton/Lewinsky affair in 1998. Results indicated that feedback improved individual and group accuracy for predictions of whether an event would occur. These types of predictions derived from group consensus were approximately 90% accurate, which was significantly higher than the average individual participant's accuracy. Neither polling nor feedback had much effect on time course predictions. The second experiment occurred during the American military action against the Taliban regime in Afghanistan in 2001. In Experiment 2, participants were polled three times to determine if increasing the number of iterated polls would improve Delphi accuracy. The results showed that accuracy improved from the first to the second poll but not from the second to the third. The groups predicted whether these scenarios would occur with approximately 75% accuracy, which was significantly higher than the accuracy of any individual participant. Once again, the Delphi procedure did not enhance time course predictions in Experiment 2.     

资本形成、工业化与经济增长:中国的转轨特征

把中国的经济转轨、增长与工业化联系起来是本文的一个尝试。作者认为 ,中国的经济增长在近年来越来越表现出静态的特征 ,至今尚不具备持续的动态改进的力量 ,而中国在 2 0世纪 80年代以后的转轨过程则又典型地表现为以新兴工业部门的进入和扩张为特征的持续的工业化过程。本文给出了一个帮助理解转轨后中国经济增长可持续性的概念框架和经验描述。在这个框架里 ,中国的经济增长在过去 1 0年来所表现出的下降趋势可以由过度的工业化进程来解释。     

浅析资本弱化与外资避税

随着现代资本结构理论的发展,国内外企业都在学习如何在实务中对其加以灵活应用,使企业价值最大化.资本弱化就是这样一种应用,其目的在于企业通过资本结构安排,改变其纳税义务,起到避税的作用.目前,来自发达国家的外资企业在这一避税手法的使用上已达到了十分成熟的阶段,再加上我国现行税制框架尚未对资本弱化进行识别、规范和控制,造成了我国大量的税收利益流失.另外,在我国已逐渐认识到问题的紧迫性的情况下,如何进行监管和控制也是一个很大的技术难题.     

天津在外资企业高出口率态势下扩大出口的对策

近年来，天津外商投资企业的出口占天津出口总额的比例一直在70％以上。这一比例高于外商投资企业出口占我国外贸出口总额的比例，外商投资企业高出口贡献率在对天津出口贸易产生重要影响的同时，也使天津的贸易结构、贸易方式、贸易主体及企业自主知识产权的形成受到了一定的制约。在外商投资企业出口贡献率持续升高的态势下，应调整出口贸易导向，制定深化天津外贸出口的政策。     

我国城乡居民收入差别测度指标评析及修正

目前，国内学者采用了多种指标测度我国的城乡居民收入差别状况，但是由于这些指标都存在一些缺陷,因而不能准确地反映实际情况。文章介绍和评析了这些测度指标，并提出了调整的城乡居民人均实际可支配收入比指标，用以修正对我国城乡居民收入差别的测度。
