An Inter-Country Comparison of the Research and Development Tax Credit.
利用美国制造业企业数据，计算多个工业国家的研发税收抵免有效税率，比较发现美国税率低于日本、加拿大和法国，且美国税率对企业研发强度变化有显著影响。
Abstract Data for a sample of U.S. manufacturing firms are used to develop effective rates of research and development (R&D) credit using the tax provisions for a number of the major industrialized nations. Rates are compared using Analysis of Variance (ANOVA). The effects of the credit on changes in R&D intensity (R&D/Sales) are also evaluated by way of two stage least square regression. The reported results show that the U.S. rate of credit is below that of many of its foreign counterparts, such as Japan, Canada, and France. Canada has the most generous rate of credit followed by Japan, France, and, lastly the United States. The foreign counterparts also offer other tax and non-tax incentives not offered in the United States. In addition, the effective rate of the U.S. credit is shown to have a significant effect on changes in R&D intensity of the firm.
