企业实际所得税率影响因素及其稳定性研究——来自我国A股上市公司的经验证据

本文采用中国非金融类A股1998—2004年425家上市公司合计2975个样本观察值的面板数据,应用随机效应模型,深入研究了影响企业实际所得税税率（ETR）的公司特征因素,在此基础上探讨了税收政策（《他000》）的变动对这些因素的影响。结果表明,上市公司规模、固定资产密度与ETR没有显著性关系;财务杠杆与ETR呈显著性负相关;同时还发现过度雇佣职工会获得地方政府的税收优惠;但盈利能力与股权结构对ETR的影响受税收政策变动的影响,当上市公司普遍享受税收优惠时,它们与ETR呈显著正相关。当税收政策变动后,它们对ETR的影响不再显著,税收的中立性得到体现。     

Entrepreneurship and the theory of taxation

A review of the literature on firm taxation reveals that the economics of entrepreneurship has not sufficiently been taken into consideration. We discuss how this affects conclusions derived from standard models of capital taxation when applied to entrepreneurial income. Some defining features of entrepreneurship important for analyzing the effects of taxation of owner-managed firms are identified. These include the lack of a well-functioning external market for entrepreneurial effort, limited access to external capital and complementarities between entrepreneurial innovation, effort and capital. Due to these constraints, the entrepreneurial project is tied to the individual owner–manager. The entrepreneur is unable to decouple saving decisions from investment decisions, and makes joint decisions on the supply of effort and capital. The return from successful entrepreneurial ventures can therefore not be readily divided into labor and capital income, in deep contrast to what is typically assumed in taxation theory. It is argued that when distinct attributes of entrepreneurship are taken into account, certain conclusions of capital taxation models may no longer hold, including the neutrality of capital taxation in owner-managed firms. Cost of capital formulas derived from the behavior of public firms could underestimate distortions when applied to the investment behavior of entrepreneurial firms. For tax purposes and otherwise, it becomes useful to analyze return to entrepreneurial activity as income of a distinct factor of production. In this context, conceptual issues and the difficulties of measuring entrepreneurial income are discussed.     

Who Cares About Corporate Taxation? Asymmetric Tax Effects on Outbound FDI

This paper investigates whether different types of FDI are asymmetrically affected by corporate taxation. We classify investment projects according to several characteristics such as the general motivation for FDI, the type of business activity, or the degree of internationalisation of the multinational firm. Subsequently, we analyse how local taxes influence the number of German outbound investments in European countries. The analysis reveals significant asymmetries with regard to tax effects: vertically integrated investments are more sensitive to host‐country taxation than horizontal FDI; larger tax rate elasticities are estimated if business activities are considered highly mobile; and in accordance with profit‐shifting considerations, subsidiaries of more internationalised companies are less tax responsive to host‐country taxation.     

On the measurement of investment types: Heterogeneity in corporate tax elasticities

This paper contributes to debates about the appropriate characterisation of heterogeneous investment types and to what extent different investment motives affect the responsiveness to corporate taxation. In particular, we employ and refine a methodology to better evaluate the tax elasticity of investment types. Using a combination of both firm‐specific information and sector‐specific information from input–output tables, we discuss how to classify investment as non‐related, horizontal, vertical and complex types. First, we point out to what extent the resulting classification depends on assumptions made by the researcher. Second, we employ an ample set of classifications and find that non‐related investment reacts stronger to corporate taxation, whereas horizontal investment is less responsive, though, significant negative tax semi‐elasticities turn out for the subset of manufacturing industries. To address inherent characteristics of vertical and complex investment, we extend the methodology and find that, by and large, stronger business motives reduce the tax responsiveness of investment to a larger extent. Given the current debates about substantial corporate tax reforms, it is all the more important to recognise that corporate tax effects can vary fundamentally between countries, driven by country‐specific differences in their composition of industries and investment types.

Abschaffung der Abgeltungsteuer — gerechter und steuersystematisch einheitlicher?

There is a rising political discussion in Germany around abolishing the final withholding tax on capital income. The German tax reforms that introduced this tax lowered tax rates, in particular on interest income. According to some authors, the growing inequality of income and property is a strong argument for the higher taxation of capital income. However, other authors argue that the neutrality aspects concerning private investment are inadequate. An abolishment of the final withholding tax would not solve these problems and, moreover, would turn back the achieved improvements. Therefore, the German Council of Economic Experts suggests complementing the previous reforms by introducing an allowance for corporate equity.     

Capital Structure Choices and Taxes: Evidence from the Australian Dividend Imputation Tax System

The introduction in 1987 of a dividend imputation tax system in Australia represented a significant change to the tax framework. To the extent that tax incentives influence the use of debt financing, changes in tax laws that alter these incentives will lead to changes in corporate capital structures. This paper examines the changes in corporate capital structure around the introduction of a dividend imputation tax system. The introduction of dividend imputation provides an incentive for firms to (a) reduce the level of debt financing utilized where this incentive varies across firms depending on the firm’s effective corporate tax rate, and (b) increase the level of external equity financing. The results present evidence consistent with these incentives.     

Why do countries combine the exemption system for the taxation of foreign profits with domestic double taxation relief?

Many European countries exempt foreign profits from domestic corporate taxation. At the shareholder level, however, all corporate profits are taxed, and double taxation relief is granted only for domestic corporate taxes. This paper attempts to rationalize this tax policy. In the presence of double taxation agreements which exempt foreign profits from domestic corporate taxation, countries may use shareholder taxes to tax these profits. The disadvantage of shareholder taxes is that they create incentives to sell domestic firms to foreigners. But double taxation relief for domestic profits may preserve domestic ownership. Our results imply that national dividend tax policies may be a factor contributing to the empirically observed home bias in investment.     

企业所得税税负归宿与收入分配

企业所得税对收入分配具有重要影响,本文将企业所得税税负归宿问题内生化来研究其对收入分配的影响,使用2010年的数据研究企业所得税的税负归宿发现,相对于国家实际征得的企业所得税,资本要素承担了超过100%的税收负担,而劳动要素在我国企业所得税的税负归宿中受益;在收入分配方面,企业所得税具有一定的累进性,能够减少城乡之间、城乡不同收入群体之间的收入分配差距.本文的研究表明,企业所得税对不同收入群体收入的影响大体呈倒U字型分布,因此,降低企业所得税虽然可能导致收入分配进一步恶化,但有利于提高最低收入阶层收入占国民总收入的比重;提高企业所得税虽然有利于调节收入分配,但应注意配合其他措施提高低收入者收入.     

Taxation and entrepreneurship in a welfare state

Does tax policy affect the rate of self-employment in a modern welfare state? This question is analyzed empirically based on Swedish data for the entire postwar period. Available tax data indicate that payroll taxes have had a negative influence on the unincorporated rate of self-employment, though the effect is modest. No effects from regular labor income taxation or capital gains taxation are found. The paper improves upon earlier studies in that it tries to separate the effects of different taxes and uses cointegration techniques. A further extension is that it studies a Scandinavian high-tax welfare state. Earlier time-series studies analyzing self-employment and taxation have, with few exceptions, been based on data from countries with relatively low tax levels and less comprehensive welfare systems, notably the USA and the UK.     

Commodity tax harmonization and the location of industry

We study the positive implications of commodity taxation and tax harmonization under the destination and origin principles when firms are monopolistic competitors facing variable demand elasticity and segmented markets. Our emphasis is on the international location of firms in the presence of market size asymmetries and trade costs. Under the destination principle, an increase in the tax rate of a country always causes some firms to relocate to the other. This effect may be reversed under the origin principle when economic integration is deep enough. Under tax harmonization the choice of a common tax principle is irrelevant for the market outcomes and for the global tax revenues. It affects, however, the distribution of revenues between small and large countries.     

非上市中小企业资本结构的决定因素分析

本文利用11723家非上市中小企业的财务数据,分析反映企业特征的因素与财务杠杆之间的关系。研究发现,在全体中小企业、国有中小企业以及民营中小企业,企业规模对长期负债率和总负债率产生正的影响,盈利性对长期负债率和总负债率产生负的影响,资产的有形性对长期负债率具有正的影响,而与总负债率之间呈负相关关系。成长性仅对全体企业和民营企业的资本结构具有一定的影响,而非债务税盾的影响较弱。企业规模、盈利性和资产的有形性是中小企业资本结构的重要影响因素。研究结果基本上支持权衡理论和优序融资理论的观点。     

Valuation and firm investment and financing policies with personal tax biases

In this paper we examine firm financial policies in the presence of personal tax biases (e.g., favoring capital gains relative to interest and dividends). A form of the value additivity principle (VAP) for the tax bias case is established and applied to the firm's merger, investment, financial structure, and dividend decisions. As with the neutral tax VAP, the revised VAP requires transaction costless capital markets but does not require capital market completeness or competitiveness. Share value maximization is found not to be the proper goal for a firm that seeks to maximize the shareholders' current expected utility; however, it is found that share value maximization is generally a good approximate objective. Firm investment policy with financial structure irrelevance (owing to offsetting personal and corporate taxes) is examined assuming that the revised VAP holds.     

Evaluating small firm performance in local context: A case study of manufacturers in Columbus,Ohio

This research approaches corporate restructuring from a place-based perspective, departing from firm or industry-specific analysis and focusing instead on the performance and problems of a local economy. The study systematizes data from a survey of small manufacturing firms in Columbus, Ohio, offering a methodology that can be used for comparative analyses of sectors within or among communities.We link the performance of firms and local context using a sampling strategy that represents local industry mix. We recognize the multidimensional character of performance and employ several indicators, stated in both static and dynamic terms. We use these indicators to identify patterns of firm performance, relative to both national and local standards. Discriminant analyses reveal variables that account for differences among groups of firms, identified by level of performance, industry, and mode of labor-management relations.Results indicate that small manufacturers in Columbus are relatively uncompetitive. The few high performing firms are investing more in labor than in capital, but most firms are investing more in capital than labor. These findings are consistent with American corporate tradition that deemphasizes workers. Effective restructuring entails more than technical change, which enables competitiveness but does not itself engender it.This project was funded by the Ohio State University Committee on Urban Affairs, #724520.     

Implications of the US Tax Reform for Transatlantic FDI

On 22 December 2017 President Trump signed the Tax Cuts and Jobs Act. This corporate tax reform can be considered the most significant amendment of the US corporate tax code since 1986. Besides the reduction of the corporate income tax rate from 35% to 21%, the Tax Cuts and Jobs Act entails features like a switch from worldwide income taxation to territorial taxation, as well as immediate deductions for certain assets. This leads to a substantial improvement for the US in global tax competition. In this paper, we analyse the effects of the US tax reform on FDI flows between Europe and the US. We find that European high-tax countries in particular will suffer from a net outflow of FDI.     

Liquidity Constraints and Investment Opportunities: New Evidence from Large and Small Businesses in the UK

In this paper, we compare the liquidity constraints and investment opportunities for large and small businesses. This is done by examining the relationship between stock liquidity and investment opportunities in a sample of large and small enterprises listed on the London Stock Exchange. We find a positive statistical association between stock liquidity and investment opportunities, regardless of the size of the enterprise. This unique result in the London Stock Exchange suggests that firm size does not influence corporate investment decisions because there is no significant change in the cost of capital between large and small enterprises.     

Does Corporate Taxation Deter Multinationals? Evidence from a Historic Event in Ireland

We use a unique exogenous corporate tax policy change in the Republic of Ireland to investigate how corporate taxation affects foreign direct investment at the extensive and intensive margin. To this end, we construct exhaustive sectoral and plant level panel data and use difference‐in‐differences strategies. Our results do not provide strong evidence that the increase in corporate tax rates for exporters did affect the entry or exit of plants from the US or UK in Ireland. Entry rates of German firms seem to be negatively affected, however. At the intensive margin, there is evidence that foreign plants in Ireland reduce the size of their operations in response to the tax change.

公司风险投资组合多元化与公司投资者价值创造——基于分位数回归的实证分析

文章基于沪深主板78家上市企业2000-2012期间686个企业观察样本所构成的非平衡面板数据,在控制了企业规模、年龄、资本支出、营收增长率、行业平均Q值等因素后,基于分位数回归模型检验公司风险投资组合多元化与公司投资者价值创造之间的关系以及组织冗余对两者关系的调节作用。研究发现：只有具备一定企业价值水平的公司投资者才可能通过公司风险投资来实现价值创造,并且公司风险投资组合多元化与企业价值创造之间存在复杂的“U形”关系;组织冗余对“U形”关系有积极的调节作用,但企业价值水平不同,则调节效应大小不同,实现价值创造的公司风险投资组合多元化临界值也就不同。因此,企业根据自身资源禀赋（价值水平和组织冗余）来选择差异化公司风险投资策略。
