浅析工业设备支撑体系方案优化的思路

设备承重支撑体系是一种特殊的结构形式,在我国工业项目中的应用范围越来越广,设备支撑结构体系类似于民建钢框架结构、钢框架-支撑结构体系。重型设备的支撑点主要集中在结构体系的局部楼层,导致上下楼层质量、刚度比例偏差较大,设备布置偏心,不满足抗震设防要求[1]。随着传统工业的工艺技术不断革新、新型工艺技术的发展、重型设备的出现,优化钢结构承重支撑体系势在必行。在满足承载能力和使用要求的前提下,可打破常规规则与相对不规则结构形式间的界限。依据结构专业设计条件[2]、操作楼层和承重楼层分别设计的优化思路,对降低钢材用量、节约项目成本具有现实意义。鉴于此,论文主要对现阶段工业承重体系的优缺点进行分析,提出其承重钢结构体系优化的构想和措施。     

新形势下完善房地产企业财务管理的研究

对于房地产企业来讲,资金运作对企业的生命周期以及工作都会产生至关重要的影响,而在资金运作过程中,财务管理工作是重中之重。因此,在现代化发展背景之下,房地产企业如何就融资渠道以及资金使用效率进行提升,并对施工过程中的预算成本进行控制,是财务管理工作需要重点解决的问题,这样才能够从根本上改善房地产企业的资金运作效率,提升房地产企业的可持续发展水平。因此,论文对新形势发展背景下房地产企业的财务管理工作优化措施进行论述。     

Do we now collect any revenue from taxing capital income?

The U.S. income tax system has long been recognized as a hybrid of an income and consumption tax system, with elements that do not fit naturally into either pure system. What it actually is has important policy implications for, among other things, understanding the impact of moving closer to a pure consumption tax regime. In this paper, we examine the nature of the U.S. income tax system by calculating the revenue and distributional implications of switching from the current system to one form of consumption tax, a modified cash flow tax.     

征税成本领先性假设与中国税务组织结构优化——兼析中国国税、地税机构是否存在合并趋势

本文从征税成本领先性假设出发探讨了中国税务组织结构的优化问题 ,并分析了社会各界广泛关注的中国国税、地税机构是否存在合并趋势的问题。本文在对中国现行税务组织机构运行绩效考察的基础上 ,发现中国征税成本曲线呈抛物线状 ,表明中国征税成本正呈递减趋势。以此为出发点 ,本文详细论证了中国国税、地税机构不存在合并的趋势 ,相反 ,分设更为彻底却是今后的发展趋势 ,得出了与一般看法不同的结论 ,并对优化中国税务组织结构提出了政策建议     

Energy taxation in Southern Europe: The case of Portugal

We investigate whether or not the imposition of a common EC energy-tax will penalize more the poorer Southern European economies and if this will harm convergence at the EC level. We start by surveying briefly the existing studies and empirical evidence. Then we exploit the results obtained when using the macroeconometric HERMES models to simulate the introduction of an energy-tax. Unfortunately, as we only have HERMES results for one Southern European economy, Portugal, our conclusions are limited. Finally, we investigate convergence in Europe and the effects of energy taxation on convergence. We conclude that energy taxation will harm growth all over the EC, penalizing more one of the less developed countries, Portugal, and having most probably adverse effects on convergence.This paper was prepared for presentation at the Conference Energy Tax in Europe organized jointly by the SEO-University of Amsterdam and the DG XII of the CEC and held in Amsterdam on 13th December 1991. I would like to thank the participants in the Conference and two anonymous referees for helpful comments. Of course, the usual disclaimer applies.     

Endogenous human capital accumulation, comparative advantage and direct vs. indirect redistribution

Recently, several papers have reexamined the so-called production efficiency theorem and the Atkinson and Stiglitz theorem on commodity taxes in the optimal taxation literature. Naito [J. Public Econ. 71 (1999) 65] showed that indirect redistribution through production distortion or consumption distortion can Pareto-improve welfare and that the two theorems do not necessarily hold when different factors are imperfect substitutes and factor prices are endogenous. On the other hand, Saez J. Public Econ. (2002) forthcoming argued that in the long run, where human capital accumulation is endogenous, the two theorems are still valid. This paper develops reasonable alternative models where individuals accumulate human capital based on their comparative advantage. The present paper shows that the production efficiency theorem is not necessarily valid and that indirect redistribution from the able to the less able such as tariffs and production subsidies can increase efficiency even when skill accumulation is endogenous.     

The optimal treatment of tax expenditures

This paper analyzes the optimal treatment of tax expenditures. It develops an optimal tax model where individuals derive utility from spending on a “contribution” good such as charitable giving. The contribution good has also a public good effect on all individuals in the economy. The government imposes linear taxes on earnings and on the contribution good so as to maximize welfare. The government may also finance directly the contribution good out of tax revenue. Optimal tax and subsidy rates on earnings and the contribution good are expressed in terms of empirically estimable parameters and the redistributive tastes of the government. The optimal subsidy on the contribution good is increasing in the size of the price elasticity of contributions, the size of the crowding out effect of public contributions on private contributions, and the size of the public good effect of the contribution good. Numerical simulations show that the optimal subsidy on contributions is fairly sensitive to the size of these parameters but that, in most cases, it should be lower than the earnings tax rate.

农村税费改革中存在的问题及对策

农村税费改革后,农民的负担减轻了,但税费改革中新出现的一些问题严重影响了税费改革的进程和效果。我国农村税费改革存在着城乡之间、城区与非城区农民之间负担不均衡、农村义务教育投入严重不足、村级经费短缺等亟待解决的问题。为此,应采取加大农村政府机构改革的步伐和力度、加大对农村义务教育的投入、加大中央和省级两级财政转移支付力度等措施,进一步完善农村税费改革。
