摘要:随着我国社会主义市场体系的不断完善，内外资企业分别实行两套所得税所带来的负面效应日益凸现，统一内外资企业所得税制度是我国税制改革的必然。2008年正式实施的新企业所得税法根据我国市场经济发展的总体要求，在“简税制、宽税基、低税率、严征管”的原则基础上，提出了“四个统一”：即内外资企业适用统一的企业所得税法、统一并适当降低企业所得税率、统一和规范税前扣除办法和标准、统一税收优惠政策。本文重点分析了两法合并对企业的影响，内资企业将和外资企业在相同的所得税标准下公平竞争，使内资企业竞争力大大增强。两法合并尽管会对我国FDI（外商直接投资）的总量有一定影响，但会提高引资质量，促进我国产业结构升级和科学技术进步。本文得出的结论是要客观辨证地看待两法合并，内资企业竞争力将大大增强，同时对外资企业也不会有太大影响，并于文章结尾提出了一些对企业应对政策变化的建议。
