Rethinking the costs related to global warming: A survey of the issues

One approach to the economic analysis of global warming seeks to balance the costs of damage from or adaptation to it with the costs of mitigating it. The costs of adaptation and damage have been estimated using techniques of environmental evaluation, but are subject to a wide margin of uncertainty. The costs of mitigation, principally by reducing the emissions of CO₂, have been estimated using different kinds of economic models, some of the results of which have suggested that very little abatement of carbon emissions is justified before the costs of abatement exceed the benefits of it in terms of foregone damage and adaptation costs. The paper analyses the extent to which this conclusion is a function of the modelling assumptions and techniques used, rather than likely practical outcomes, with regard to the models' treatment of unemployed resources, revenue recycling, prior distortions in the economy due to the tax system and possible dynamic effects from the introduction of a carbon-energy tax. It concludes that, with different and arguably more appropriate treatment of the above issues, especially when the secondary benefits of reducing CO₂ emissions are also taken into account, it is not clear that even substantial reductions in the use of fossil fuels will incur net costs, especially if there is the prospect of even moderate costs from global warming.     

Domestic and international strategic interactions in environment policy formation

Summary. In this paper, we establish the most possilbe general formulation of the technology governing carbon-gas emission, giving rise to global external diseconomies, and ty to explore into the strategic interactions,both domestic and international, when an individual country decides on the environmental policies. Through the comparison among emission taxes, quotas, and standard in the perfectly competitive private economies, we find that the first two policies are equivalent but they are different in effects by virtue of what we may call the tax-exemption effect of emission standards. Such a difference in the policy effect further affects the other country's welfare through the global externalities, amplified through whether the government can precommit to either the emission tax or the emission standard.

物业税可行吗？

物业税作为一种财产税，具有其自身的特征。未来我国在物业税的设计过程中需要考虑多种因素，规避相关风险，否则很可能使得现在的高房价变成未来的高额物业税。     

浅析我国企业所得税改革——写在2007年“税合一”出台之际

2007年3月14日，提交全国人大审议的企业所得税法草案规定，将内外资企业所得税税率统一为25％，法定税率由33％降低了8个百分点。外资实际税率要从15％变成25％，内资要从33％下降到25％。大多数的声音是，这项政策对外资企业是一种公平合理的国民待遇，对内资企业则是一种重要的激励。这将会使市场竞争朝着更加公平的方向发展。本文通过对这项具有里程碑意义的税改政策出台的背景、影响等方面加以综合分析，并归纳整理了该政策出台后理论界、业界的不同观点，为新税制的发展提供了展望。     

我国省际间财政差异趋势与影响因素的实证研究

本文通过1980-2005年间的样本数据,揭示1980年以来我国省际间财政差异的变化趋势,以及这种变化趋势的影响因素.我们的研究表明,在财政收入方面,受地区经济差异加大的影响,1994年以后财政收入差异有扩大态势,而分税制改革有助于缩小省际间财政收入差异.在财政支出方面,1995年以后财政支出差异呈上升趋势,这是地区间经济发展水平差异与分税制共同作用的结果,但是前者的作用远远大于后者.因此,缩小省际间财政差异的途径除转移支付外,还应当主要致力于缩小省际间经济发展水平差异.     

OECD税制绿色化与我国之借鉴

OECD成员国在实现税制绿色化方面采取的值得我国借鉴的措施有:取消或修正现行扭曲性的补贴和税收条款,调整现行税制,开征新的环境税.基于对我国现实国情的考虑,将实现税制绿色化的重点放在开征新的环境税-环境污染税和某些资源税上,并以改革现行税制与逐步消除对环境不利的补贴政策辅助之.     

金融工具会计准则交易税制设计的思考

为了规范金融工具的确认和计量,反映金融工具对金融机构财务状况和经营成果所带来的真实影响,揭示其潜在风险,提高金融机构的会计信息的质量,新颁布的金融工具会计准则采用公允价值计量,并将损益纳入当期损益。本文分析了此举对我国税制所产生的影响,并对金融工具交易的税制设计提出了设想。     

关于完善地方税体系的探讨

地方税体系是分税制财政管理体制的重要组成部分，是我国目前在理论和实践中尚未解决好的问题，提出了完善地方税体系应坚持的原则，在原则指导下，借鉴国外的经验，合理划分中央和地方税收管理权限，科学界定税种归属；优化地方税制结构，完善地方税体系。     

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.     

增值税转型对企业的财务影响分析及转型条件

加入WTO以后的今天,公众呼吁营造一个公平竞争的外部环境,增值税转型呼之欲出。本文通过建立数学模型和引入实例分析了增值税转型对企业应纳税金方面的财务影响,最后引出增值税转型需要考虑的条件,认为在目前经济趋于过热的形势下,加上企业所得税没有合并的条件下,增值税转型应暂缓实行。
