基于目标替代率的税延型商业养老保险扣除限额优化研究

我国养老保障体系三支柱发展严重失衡,为了缓解基本养老保险的压力,提升养老保险替代率,商业养老保险的发展迫在眉睫,税收递延型商业养老保险也开始试点。在2018年个税改革后,目前税收递延型商业养老保险推行办法下,中低收入群体无法享受实际税收优惠,高收入群体可享受的税收优惠有限且过低。本文以替代率为基准,根据精算平衡原理构建模型,对扣除限额进行优化研究,试图测算出与新个税办法匹配且有利于多层次收入水平的消费个体享受实际税优的扣除限额。同时,本文还对不同扣除限额下开始购买保险年龄、个税起征点、个人收益率及初始收入水平这四个参数变化对实际税优额的影响做了分析,得出所测算出的扣除限额的确较现行扣除限额更为合理,并提出了相关对策建议。     

Progression and revenue effects of income tax reform

Usually, only initial revenue effects of personal income tax reforms are considered. However, a tax reform characterized by base broadening in exchange for rate reduction can reduce the income elasticity of tax revenue. In that case, the increase in revenue after income growth will be relatively smaller: the tax reform has a negative effect on revenue in the second period. Using the microtax model of the Central Planning Bureau we simulated the effects of the Dutch Oort reform 1990 on revenue elasticities and, consequently, on tax revenue. The income tax revenue elasticity declined by 17 percent which caused an additional revenue loss of 0.6 percent in 1990, rising to 3.8 percent in 1993.     

China''''s Cooperative Exploration of Oil and Gas and Its Taxation System

China' s foreign-oriented oil taxation system has, from the beginning, been based upon the positive experiences of other oil-producing countries and has incorporated common international practices. The system has been perfected over decades. It of fers more incentives than other oil-producing countries in the following four aspects: (1) Income tax has a "wide tax base and low tax rate"; (2) VAT levies a low tax rate on ma-     

Tax Competition and International Public Goods

A well known result in the tax competition literature is that tax rates are set too low in the Nash equilibrium to finance an efficient level of public consumption goods. In this model we introduce international spillovers in public goods provision and show that such spillovers reduce, and in the limiting case of perfect spillovers, eliminate tax competition. There is, however, always underprovision of the public good in equilibrium, since larger spillovers increase the problem of free riding. In an extension to the model, we demonstrate that congestion costs may result in overprovision of the public good.     

Why Capital Income Taxes Survive in Open Economies: The Role of Multinational Firms

This paper discusses the role of multinational firms and double taxation treaties for corporate income taxation in open economies. We show that it is optimal for a small open economy to levy positive corporate income taxes if multinational firms are taxed according to the full taxation after deduction system or the foreign tax credit system. Positive corporate taxes also occur in the asymmetric case where some countries apply the exemption system and others apply the tax credit system. If all countries apply the exemption system, the optimal corporate income tax is zero. We also show that, under tax competition, corporate income taxes are not necessarily too low from the perspective of the economy as a whole. While the undertaxation result is confirmed for the case of the exemption system, tax rates may also be inefficiently high if the deduction or the credit systems are applied.     

我国保险公司税收制度的完善

中国经济改革与增长中的金融支持

中国的金融制度变迁也服从了渐进改革的“过渡性”逻辑 ,渐进战略较好地支持了中国 2 0年的经济增长。但是 ,由于“双轨”体制的固有矛盾 ,使中国的金融改革在今天聚集到了深层次的金融改革上 ,而这一问题的核心是多元化的金融产权关系。中国加入WTO成为中国金融深化改革的契机。摆在面前的来自外部世界的竞争 ,成为推进中国金融业“对内开放”的巨大的外部冲击
