企业成本加成率为深入理解产品市场竞争和劳动收入分配之间的内在关联提供了关键切入点。文章构建了一个成本加成率内生的一般均衡模型,分析了企业成本加成率上升对内部收入分配的影响。基于2011—2023年中国上市公司财务报表数据,文章实证检验了理论模型的结论。研究发现,企业成本加成率上升使得员工平均薪酬和劳动收入份额显著提高,同时也造成了内部薪酬不平等的扩大。机制分析发现,产品市场竞争激励在位企业降低边际成本,以维持竞争优势,由此提高的成本加成率更多地补偿了促进创新的高管和研发人员,进而导致了劳动收入份额提高和薪酬不平等扩大。异质性分析发现,在生产集中缓慢、行政监管较弱和处于成长期的竞争性行业中,企业加成率对员工薪酬的推升作用更强,且扩大了管理层内部的收入分布差距。文章的发现对于理解公平竞争政策与收入分配之间的联系具有重要借鉴意义。
