【摘要】 近年来，税费优惠作为带动企业转型升级的重要政策手段，有利于促进制造业企业技术创新。本文选取2015-2021年1396家A股制造业上市公司数据，就税费优惠对制造业上市公司技术创新影响进行实证研究。研究结果显示：税费优惠能够促进制造业企业提升技术创新。考虑企业类型及地区差异，税费优惠对高技术制造业技术创新投入越大，技术创新绩效越大，且独立技术创新优于联合技术创新。同时，经济发达地区效果明显好于经济欠发达地区。基于研究结果，建议进一步完善税费优惠政策提升精准性，细化政策体系，鼓励企业加强开展联合技术创新，以此促进制造业企业全面创新；根据不同企业类型及区域经济发展情况，有针对性地采取差异化政策策略，促使我国制造业整体协调发展。更多还原
