我国企业所得税征管效率测度分析

高效的税收征管是良好税制的重要内容和保障,也是税制改革成功的基本条件。本文在对2000年以来我国企业所得税征管效率测度的基础上,进一步分析了近年来我国企业所得税及征管制度改革的征管效应。研究发现,近年我国企业所得税征管效率呈波浪式上升态势,效率水平还有较大提升空间;在当前情况下,国税局企业所得税征收比重的提高将会降低企业所得税征管效率,企业所得税占税收收入比重越高、在税收部门征管中越重要,就更有助于企业所得税征管效率的提升;2002年、2006年和2009年企业所得税、国地税征管责任分工调整改革,对税收征管效率的影响不显著,2008年内外资企业所得税统一改革,显著提升了企业所得税征管效率。     

STATUS QUO IN THE WELFARE ANALYSIS OF TAX REFORMS

The welfare analysis of tax reforms most often consists of comparing the post‐reform distribution of individual welfare with the pre‐reform distribution or possibly that obtained from another reform as if they were completely independent. Such an “anonymous” approach does not take into account “changes” in individual situations, generally the main source of contention in any tax reform debate. This paper proposes a welfare criterion that allows comparison of reforms while taking into account individual status quo—i.e. pre‐reform—situations. This is done by extending standard utilitarian social welfare criteria to the case where individual utilities depend on initial income and income change.     

TAX REFORM

After brief individual presentations, panelists discuss among themselves and with the audience a broad spectrum of issues regarding various taxes and tax reform proposals. The discussion includes such issues as privatizing Social Security and Medicare, eliminating income tax withholding, and the merits and demerits of income taxes, consumption taxes, value added taxes, sales taxes, and taxes on resources that have an inelastic supply. One panelist relates his recent experiences using his tools as an economist to deal with tax and related issues as a current member of the Canadian Parliament. Another cites practical problems of implementing tax reform from his long experience advising governments, especially in Latin America. A major focus of the exchange of views is on public choice problems involved in passing and implementing a so-called flat tax. However, the discussion also deals with economic efficiency and equity considerations and with nearly all other types of taxes. The discussion includes not only the impact on the country within which tax reform occurs, but international implications, as well.     

ASSESSING THE WELFARE IMPACT OF TAX REFORM: A CASE STUDY OF THE 2001 U.S. TAX CUT

This paper implements a relatively simple methodological approach to estimate the impact on family welfare of a specific tax reform. The measured impact can differ greatly from simple marginal tax rate comparisons, and conclusions about the distribution of the welfare impact can vary depending on the basis of comparison. For example, absolute welfare gains from the 2001 U.S. tax reform were concentrated among the highest and lowest income families, whereas welfare gains measured as a share of pre‐tax income are found to be nearly monotonically declining in income.     

ENDOGENOUS FERTILITY AND THE CONSUMPTION TAX*

The differential incidence between the consumption tax and the labour income tax is examined in a model where altruistic parents decide the number of children endogenously. In contrast with past results, the consumption tax is not neutral and exerts distortional effects. As a result, welfare gets worse off through the tax reform of switching from a labour income tax to a consumption tax. This provides the argument about the treatment of bequests under a consumption tax.     

关于个税起征点的研究

本文提供了一种方法,即通过数值模拟,考察了个人所得税起征点和劳动就业率、社会公平以及社会福利水平的相互关系。本文以搜寻和匹配模型为基础,根据我国目前个人所得税制度中对分级税率和税级距的设定,通过数值模拟的方法计算了合理的个人所得税起征点。计算结果显示:(1)中国的个人所得税起征点仍有一定的提升空间,但空间并不大。(2)提高起征点可以增加就业,若将起征点由2000元提高到2800元,就业率可以提高两个百分点。但起征点从2800元再继续提高,对就业的促进作用就微乎其微了。(3)提高个人所得税起征点在一定程度上损害了社会公平。因此,要兼顾社会公平,个人所得税起征点不宜过高。我国的个人所得税改革不应该强调起征点,以家庭作为课税单位才是个人所得税改革的重点和方向。     

THE INCOME REDISTRIBUTION EFFECT OF CHINA'S PERSONAL INCOME TAX: WHAT THE MICRO‐DATA SAY

This article uses continuous micro‐level data to investigate the income redistribution effect of the personal income tax (PIT) in China beginning in 1997. We find that the average tax rate plays a larger role in determining the income redistribution effect of PIT than tax progressivity does. Although tax progressivity decreased as a result of rising personal incomes and a constant PIT policy prior to 2005, the income redistribution effect of the PIT improved as a result of the higher average tax rate. The tax reform beginning in 2006 increased tax progressivity while decreasing the average tax rate, thereby weakening the income redistribution effect of the PIT. Further analysis indicates that the middle‐income group was the only net loser before 2005, but it benefited from the PIT policy reform. A cross‐country comparison shows that China has a lower PIT burden and higher progressivity than developed countries; in fact, China's levels of progressivity and tax burden are similar to those of Latin American countries.

生态赤字税：绿色发展与税制改革*

本文在量化生态占用并评估生态价值基础上,提出运用税收实现超额生态占用价值补偿的税收方案,也称生态赤字税。根据税制生态化的改革思路,本文运用CGE模型分析了征收生态赤字税和降低所得税的政策效应。本文研究发现：(1)在各税收方案中,生态赤字减少,就业增加,支持双重红利假说,全行业中间投入减少相对总产出减少更大,名义GDP保持增长;(2)实际GDP在生态赤字税基础上仅减少企业所得税的方案中下降,同时减少个人所得税则能实现增长,此时减税额低于生态赤字税收入;(3)在开征生态赤字税同时,降低个人所得税在保持经济增长方面较好,降低企业所得税在减少生态赤字方面较好,但降低企业所得税所减少的生态赤字价值低于降低个人所得税时劳动和资本增加值的提高。本文建议在完善生态占用核算基础上开征生态赤字税,并减轻所得税,促进经济增长由资源环境消耗转向劳动和资本投入的绿色发展。     

LONG‐RUN GROWTH AND WELFARE EFFECTS OF TAX REFORM

This paper introduces an endogenously‐determined fertility rate into a Romer‐type endogenous growth model and, accordingly, investigates the effects on fertility, economic growth and social welfare of a revenue‐neutral tax reform that involves switching from an income tax to a consumption tax. We show that, in a departure from the existing literature, tax reform could be harmful, rather than favourable, to both growth and welfare, due to an endogenous fertility rate. We also conduct a simple numerical analysis to investigate under what conditions the negative effect on growth and welfare occurs.     

WHO PAYS NO TAX? THE DECLINING FRACTION PAYING INCOME TAXES AND INCREASING TAX PROGRESSIVITY

Using federal individual income tax data, this paper presents the first long‐run estimates of the fraction paying no income tax. Between 1985 and 2015, the fraction of working age adults paying no tax increased from 20% to 36%. A decomposition shows that almost all of this increase resulted from changes in tax policy, especially from more generous tax credits. Increasing tax progressivity over the last three decades also resulted from more generous tax credits. The substantial federal tax changes enacted in 2017 are forecasted to temporarily increase both the fraction paying no tax and individual income tax progressivity. (JEL H22, H24, H31)     

我国个人所得税：如何调节收入分配

传统观点认为个人所得税是公平与效率权衡的产物。但是,这种结论并没有考虑逃税因素。如果将逃税因素纳入分析框架,个人所得税调节收入分配的机制在不同条件下将存在差异,公平与效率可能同时实现。本文从公众收入中存在的隐性收入出发,分析了这种收入对个人所得税调节收入分配的影响,并总结出个人所得税存在高结构累进性与低结构累进性两种再分配机制。对于我国而言,低结构累进性的个人所得税才能发挥调节收入分配的作用。     

新发展阶段与建立现代财税体制*

本文基于我国即将进入全面建设社会主义现代化国家新征程的新发展阶段,回顾了党的十八大以来的财税改革经验,锚定“十四五”规划和2035年远景目标,研究了新发展阶段对深化财税体制改革的要求,从深化预算体制改革、理顺央地财政关系、提升现代税收治理、健全债务管理制度、推进财税法治建设五个方面把握中国特色现代财税体制发展,持续为建立现代财税体制提供理论佐证。     

EFFECTS OF PERSONAL INCOME TAX ON INCOME DISTRIBUTION: EXAMPLE FROM BULGARIA

This study utilizes the 1992 Bulgarian household budget survey to analyze the distribution of income and income tax burden. Results indicate that the country is characterized by low income inequality, though this is changing rapidly. The findings also show that the present income tax system is progressive and that the urban sector pays much more relative to its income. Despite a steeply graduated statutory tax rate schedule, effective progression is rather modest, indicating significant tax evasion. However, one must view the results of progressivity and urban bias cautiously. As in-kind income becomes monetized and as the economy becomes more market-oriented, both progressivity and urban/rural differences will wane over time.     

在三大超越中准确把握共同富裕的理论基础、实践基础和规划纲领*

十九届六中全会审议通过了《中共中央关于党的百年奋斗重大成就和历史经验的决议》，明确了新时代党面临的主要任务。新时期扎实推动共同富裕，需要在三大超越中准确把握共同富裕的理论基础、实践基础和规划纲领。一是必须超越简单的社会运动，从经济、社会和政治等层面认识到共同富裕具有坚实的经济理论、社会理论和政治理论基础，逐步推进共同富裕是我国经济循环畅通、社会秩序和谐、政治基础夯实的必然要求。二是必须超越简单的理论逻辑推演，从历史实践的角度来全面把握当前推进共同富裕是中国特色社会主义在完成全面建设小康目标、乘势而上全面实现现代化的必然选择，具有坚实的历史基础和实践基础。三是必须超越一般的思想争论，在理论的批判中通过构建科学的实施方案和可实施的路径，在实践中不断深化对于共同富裕的认识，在高质量发展中扎实推进共同富裕示范区建设，构建三大分配协调配套的基础性制度安排。     

新个税存在的问题及解决措施

为进一步完善个人所得税税制,2011年新个人所得税（以下简称“新个税”）法案应运而生。对于实行以3500元的免征额为主要改革内容的新个税能否够切实摆脱中国个税陷入的困境,实现缩小贫富差距、社会公平的目标,大多持怀疑的态度。针对这一问题,以新个税为基础,结合国外的主要税制模式,分析中国个税制度仍存在的问题．进而为中国个税今后的改革方向提出几点建议。     

企业避税与年报可读性

避税活动加剧了企业的信息不对称，管理层在信息披露中是否会采用晦涩的文本信息掩盖避税行为？本文利用2008—2017年中国A股上市公司数据，考察企业避税对年报可读性的影响及其机制。结果发现，避税活动越多，企业年报采用的复杂词汇就越多，年报可读性就越差。在运用工具变量弱化内生性问题、更替年报可读性指标与企业避税指标、考虑递延所得税信息披露和税收政策影响等一系列稳健性检验后，避税行为降低企业年报可读性的结论依然成立。机制分析发现会计信息质量在避税行为对年报可读性的影响中发挥了部分中介作用，避税活动通过降低会计信息质量削弱了年报可读性，信息披露中文本信息与数字信息相配合的观点从企业避税视角得到了验证。此外，在无税收优惠、递延所得税负债较多和外部治理环境较差的企业中，避税降低年报可读性的现象更为明显。因此，规范企业税收制度能够减少企业避税、限制管理层寻租行为，促进税收透明化，从而提高企业的信息披露质量。     

对我国结构性减税问题的思考

本文认为,结构性减税就是要在税收总规模不变甚至适当增加的前提下，削减一些特定纳税人或特定税收项目的税负，其中最主要的是要削减中低收入者缴纳或负担的税收；在减税的方案上，主要是降低对人民衣食住行课征的增值税和营业税并全面推开“营改增”，适时调减企业所得税税率，并在工薪个人所得税制度中加进个性化的费用扣除标准。上述降税的收入损失可以通过提高消费税和个人所得税最高税率的办法加以弥补。     

A TALE OF TAX POLICIES IN OPEN ECONOMIES

To evaluate fiscal policy reforms for Euro‐area countries, this article develops and calibrates a small open economy model. Debt reduction reforms require higher tax rates in the short term in exchange for lower rates in the long term as the debt‐servicing burden falls. Using the capital income tax to implement such a policy leads to welfare gains; the consumption tax, a very small welfare gain; and the labor income tax, a welfare loss. Holding fixed the long‐run debt–output ratio, offsetting a lower capital income tax with either a higher labor income or consumption tax generally yields welfare gains.     

REDISTRIBUTIVE EFFECT OF INCOME TAXATION: DECOMPOSING TAX BASE AND TAX RATES EFFECTS

This paper introduces Gini-based decomposition formulae for the redistributive effect of income taxation. It examines the interaction between and the relative significance of tax base and tax rate components in the final determination of the overall redistributive effect. The resulting formulae can readily be applied to available income and tax statistics.     

TAX DATA FOR WEALTH CONCENTRATION ANALYSIS: AN APPLICATION TO SPANISH WEALTH TAX

As recent studies in different countries show, tax data offer the opportunity to estimate income or wealth shares for the upper income groups. However, several critical points must be considered in order to avoid misleading conclusions: the interpolation technique used, legal amendments, and tax fraud. In this note we take Spanish wealth tax as a case study to assess the importance of these factors, and compare our results with those obtained by Alvaredo and Saez (2009 ). Although the results of the two analyses are very similar, our approach complements theirs by offering a more precise treatment of the correction of fiscal underassessment and tax fraud in real estate, which is the main asset in Spaniards' portfolios.
