现行财务会计系统主要是基于权责发生制亦即应计制下的历史成本会计,对收入和费用确认时间的基础是实际影响期间而非现金收付发生时间。因此,对应计项目的确认就不可避免地要依赖于管理者和会计人员的主观估计和判断,从而导致应计项目金额与实际现金流金额往往存在不同程度的差异,而历年差异变动的程度可用于度量应计项目的质量。本文以1992-2004年财务数据为样本,对中国A股上市公司应计质量问题进行了研究。 相似文献

重渡沟"景区公司+农户"的旅游产业组织模式研究 总被引:13,自引:0,他引:13
重渡沟"景区公司 农户"模式是一种基于农村社区的旅游产业组织方式,其本质就是互补品生产企业在不涉及产权的情况下,在经营层面上实现的一体化,是旅游目的地内部具有地方政府背景和主导地位的景区开发管理公司为实现地方旅游业持续发展而作出的必然选择。公司对农家旅馆的低价格定价、质量管理以及对农家旅馆市场的垄断都是对产权缺失的一种弥补。"景区公司 农户"模式有效地约束了机会主义行为的发生,保证了旅游目的地的健康、持续发展。 相似文献

积极财政政策宏观经济效益分析——基于宏观计量模型的研究 总被引:2,自引:0,他引:2
龚刚 《数量经济技术经济研究》2006,23(12):3-13
本文通过一个宏观计量模型来研究积极财政政策的宏观经济效益。与传统模型所不同的是,我们的模型不仅考虑了需求,同时也引入了社会的供给能力。研究表明,积极财政政策的实施为我国在2003年底彻底走出通货紧缩的阴影作出了不可磨灭的贡献。而到了2002年,积极财政政策的拉动效应开始递减,这为此后逐渐淡出的积极财政政策提供了一定的依据。 相似文献

We consider whether oil prices can account for business cycle asymmetries. We test for asymmetries based on the Markov switching
autoregressive model popularized by Hamilton (1989), using the tests devised by Clements and Krolzig (2000). We find evidence
against the conventional wisdom that recessions are more violent than expansions: while some part of the downturn in economic
activity that characterises recessionary periods can be attributed to dramatic changes in the price of oil, post-War US economic
growth is characterized by the steepness of expansions.

Despite the abundant research on material flows and the growing recognition of the need to dematerialize the economy, business enterprises are still not making the best possible use of the many opportunities for material efficiency improvements. This article proposes one possible solution: material efficiency services provided by outside suppliers. It also introduces a conceptual framework for the analysis of different business models for eco-efficient services and applies the framework to material efficiency services. Four business models are outlined and their feasibility is studied from an empirical vantage point. In contrast to much of the previous research, special emphasis is laid on the financial aspects. It appears that the most promising business models are ‘material efficiency as additional service’ and ‘material flow management service’. Depending on the business model, prominent material efficiency service providers differ from large companies that offer multiple products and/or services to smaller, specialized providers. Potential clients (users) typically lack the resources (expertise, management's time or initial funds) to conduct material efficiency improvements themselves. Customers are more likely to use material efficiency services that relate to support materials or side-streams rather than those that are at the core of production. Potential client organizations with a strategy of outsourcing support activities and with experience of outsourcing are more keen to use material efficiency services. 相似文献

There is a wide literature on the dynamic adjustment of employment and its relationship with the business cycle. In this
paper we present a statistical model that offers a congruent representation of part of the UK labour market since the mid
1960s. We use a cointegrated vector autoregressive Markov-switching model in which some parameters change according to the
phase of the business cycle. Output, employment, labour supply and real earnings are found to have a common cyclical component.
The long run dynamics are characterized by one cointegrating vector relating unemployment to trend-adjusted real wages and
output. Despite there having been many changes affecting this sector of the UK economy, the Markov-switching vector-equilibrium-correction
model with three regimes (representing recession, normal growth, and high growth) provides a good characterization of the
sample data, and performs well relative to alternative linear and non-linear models. The results of an impulse-response analysis
highlight the dangers of using VARs when the constancy of the estimated coefficients has not been established, and demonstrate
the advantages of generating regime dependent responses.

We analyze the learning behaviour of a Simple Genetic Algorithm in an overlapping generations model with one consumption
good and fiat money. It is shown by simulations, that in cases where periodic equilibria exist the equilibrium of period two
is learned by a Genetic Algorithm and not the monetary steady state. We further show that proper coding leads to convergence
of the GA towards the sunspot equilibrium. If individuals who believe in the impact of sunspots are brought together with
individuals who ignore the sunspots, the sunspot believes will in most cases drive the other individuals out of the population. 相似文献

对蒙代尔-弗莱明模型的修正--中国经济增长对人民币汇率作用机制 总被引:6,自引:0,他引:6
蒙代尔-弗菜明模型认为,经济增长会使一国经常账户恶化从而导致本国货币贬值,中国自1994年以来经济快速增长,而经常账户却是持续顺差,在利率不断下降条件下,资金大量流入,人民币汇率稳中有升,外汇储备大幅度增加,这些显然有悖于蒙代尔-弗菜明模型。本文认为,购买力平价理论更符合中国现实,并给出了购买力平价理论动态表述,然后对传统的汇率货币模型进行修正,进一步分析经济增长与汇率之间关系。最后本文对蒙代尔-弗莱明模型国际收支平衡线进行修正,并运用修正后的M-F模型分析在开放经济条件下的财政政策与货币政策效果。 相似文献
