摘　　要：为了保障自身的科学技术优势,美国一直对外实施高科技技术封锁政策。随着中国经济水平和科技水平的提高,美国等发达国家对中国的技术优势越来越小,美国开始逐步对中国实施了技术封锁。一旦有企业被美国实施技术封锁,整个行业的企业都将面临未来发展的不确定性,那么这些企业是加大投入突破“卡脖子”技术,还是转向低端发展模式呢?根据2011—2021年中国A股上市的非金融公司数据研究结果表明,技术封锁会导致整个行业的企业增加研发投入,而且创新水平越高的企业增加的幅度就越大。国有企业和非国有企业的分样本检验也支持这一结果,而且国有企业对于技术封锁更为敏感,对研发投入增加的幅度更大。安慰剂检验和平行趋势检验也验证了本文结论的可靠性。这一结果意味着,虽然开放有利于经济和科技水平的提升,但是应当始终坚持自主创新的发展战略。In order to safeguard its own scientific and technological advantages,the U.S.has been implementing a policy of high-tech technology embargo on foreign countries.With the improvement of China's economic level and science and technology level,the developed countries such as the U.S.have less and less technological advantages over China.The U.S.began to gradually implement a technology embargo on China.Once an enterprise is blocked by the U.S.,the whole industry will face uncertainty of future development,so will these enterprises invest more to break through the“choke”technology,or turn to low-end development mode?According to a study of non-financial companies listed on the A-share market in China from 2011 to 2021,the technology embargo will lead to an increase in R&D investment for the entire industry,and the higher the level of innovation,the greater the increase.The subsample robustness of state-owned and non-state-owned firms also supports this result,and state-owned firms are more sensitive to technology embargoes and increase their R&D investment more.Placebo tests and parallel trend tests also verify the reliability of the paper's findings.This result implies that although openness is beneficial for economic and technological advancement,the development strategy of independent innovation should always be adhered to.
