基于2014~2022年中国高科技上市企业样本，分析美国实体清单制裁对行业内未被制裁企业技术原创性的溢出效应。研究发现：实体清单制裁提高了未被制裁企业的技术风险，促使其提高技术原创性。实体清单制裁的新颖性、破坏性和关键性增强了实体清单制裁对未被制裁企业技术原创性的直接影响：制裁事件发生越早、未被制裁企业对被制裁企业以及美国的技术依赖程度越高，实体清单制裁对未被制裁企业技术原创性的正向影响越强。进一步分析发现，企业研发强度越高，以及在北约地区子公司数量越多，实体清单制裁对技术原创性的正向影响越强。

Based on a sample of high-tech listed firms in China from 2014 to 2022, this study analyzes the spillover effects of the U.S. Entity List sanctions on the technology originality of non-sanctioned firms within the industry. The research finds that the Entity List sanctions increase the technological risks faced by non-sanctioned firms, prompting them to enhance their technology originality. The novelty, disruption, and criticality of the Entity List sanctions strengthen their direct impact on the technology originality. Specifically, the earlier the Entity List sanction event occurred and the higher the technological dependence of non-sanctioned firms on the sanctioned firms and the U.S., the stronger the positive impact of the sanctions on the technology originality. Further analysis reveals that the higher the firm’s R&D intensity and the greater the number of subsidiaries in NATO region, the stronger the positive impact of the sanctions on technology originality.
