“营改增”以来制造业税收优惠政策效果研究——基于江苏A股上市公司数据的分析

Research on the Effect of Tax Preferential Policies in the Manufacturing Industry since the Reform of Business Tax to Value Added Tax——Analysis Based on Data of Jiangsu A-share Listed Companies

《中国制造2025》发布以来,制造业税收支持力度不断加大。以2016—2020年江苏A股上市公司作为样本研究发现,制造业税收优惠政策在降税减负方面效果明显;但创新激励效果存在预期偏差,而短期利益驱使下企业研发支出费用化偏好是导致该问题的重要原因。完善企业研发管理制度、规范研发支出核算、加强税务精准化监管是解决这一问题的关键。

Since the release of“Made in China 2025”,the manufacturing tax support has been increasing.Using the A-share listed companies in Jiangsu from 2016 to 2020 as a sample,it was found that the tax incentives in the manufacturing industry have a significant effect on reducing taxes and burdens;However,there is expected bias in the effectiveness of innovation incentives,and the preference for expensing R&D expenses driven by short-term benefits is an important reason for this problem.Improving the R&D management system of enterprises,standardizing the accounting of R&D expenses,and strengthening precise tax supervision are the key to solving this problem.
