7393多产品企业出口在我国对外出口中一直扮演着十分重要的角色。随着中间品贸易在全球贸易中重要性的逐步提高，在当前逆全球化态势愈演愈烈的情况下，研究多产品企业在面对贸易自由化冲击时，如何通过调整其不同产品的成本加成，优化企业内资源配置并提高企业竞争力，具有十分重要的意义。文章基于修改后的De Loecker等（2016）方法，估计了中国制造业企业在产品层面的成本加成，并利用中国工业企业和海关数据，研究了我国多产品企业在中间品贸易自由化条件下，对其内部不同类型产品成本加成的调整差异。研究表明，进口中间产品关税下降会促使多产品出口企业提高其出口产品的成本加成，且对非核心产品成本加成的调整幅度更大；随着产品排序的增大，企业对其成本加成的调整幅度也增大。也就是说，中间品贸易自由化有助于缩小企业内部核心与非核心产品间成本加成的差异，进而优化企业内资源配置。影响机制分析与内生性和稳健性检验进一步支持了文章的研究结论。文章的研究对于进一步提高当前贸易摩擦频发环境下我国出口企业的抗压能力和整体竞争力，推动形成全面开放的贸易新格局具有一定的启示意义。
