中文摘要：	党的二十大报告提出，“加强基础研究”。自2018年《国务院关于全面加强基础科学研究的若干意见》发布以来，习近平总书记在多次报告中提到“切实加强基础研究，夯实科技自立自强根基”，基础研究已经在建设世界科技强国之路上扮演了举足轻重的角色。同时，战略性新兴产业政策自2010年9月发布，始终致力于推动企业参与高质量创新，“十四五”规划中再次强调了要发展壮大战略性新兴产业。 基于以上背景，本文对“战略性新兴产业政策对企业基础研究的影响”展开研究。文章采用了理论研究与实证检验相结合的研究方法，在充分梳理已有文献、相关理论和发展现状的基础上，分析了战略性新兴产业对企业基础研究的影响；然后通过使用2006-2021年中国沪深两市上市公司的数据进行了实证检验。本文使用双重差分模型和倾向得分匹配-双重差分模型，分别估计了战略性新兴产业政策实施对企业基础研究的影响。实证结果显示，战略性新兴产业政策在1%的置信水平下对企业发表论文数、企业和高校或科研院所合作发明专利数和企业发明专利数有显著的促进作用；并通过安慰剂检验和更换倾向得分匹配的方法进行稳健性检验。针对研究结果，本文进一步分析并验证了基于企业产权性质、资产规模和所在地区的战略性新兴产业政策的异质性影响。此外，本文还验证了企业不同层面基础研究对企业绩效的影响，结果显示只有应用基础研究可以显著提高企业资产收益率。 本文的理论分析与实证检验都表明：战略性新兴产业对企业基础研究有明显的促进作用，且基于企业产权性质、资产规模和所在地区产生异质性影响。同时证明了，不同层面企业基础研究对企业绩效将产生不同的影响。基于此研究结论，本文为未来探究企业基础研究提供了新的视角，并对企业制定自身基础研究战略和政府产业政策的出台提供了重要的管理启示。企业应继续加大在基础研究方面的投入，推动产学研一体化，选择适合企业自身的基础研究模式。对政府而言，应进一步加大对企业基础研究的支持，优化相关政策内容。
英文摘要：	The 20th Party Congress report proposed "Strengthening Basic Research." Since the release of the "Several Opinions of the State Council on Strengthening the Comprehensive Basic Science Research" in 2018, General Secretary Xi Jinping has repeatedly emphasized in several reports the need to "effectively strengthen basic research, consolidate the foundation of scientific and technological self-reliance," and basic research has played a crucial role in building a world-leading science and technology country. At the same time, the strategic emerging industry policy, which was released in September 2010, has been committed to promoting enterprise participation in high-quality innovation, and the "14th Five-Year Plan" once again emphasizes the need to develop and strengthen strategic emerging industries. Based on above, this article explores the impact of the strategic emerging industry policy on corporate basic research. The study adopts a research method that combines theoretical research with empirical testing. Based on the comprehensive review of existing literature, relevant theories, and development status, the article analyzes the impact of strategic emerging industries on corporate basic research. The study then conducts empirical testing using data from listed companies on the Shanghai and Shenzhen stock exchanges from 2006 to 2021. This paper uses the DID method and PSM-DID method to estimate the impact of the strategic emerging industry policy on corporate basic research. The empirical results show that the strategic emerging industry policy has a significant promotion effect on the number of published papers, the number of patented inventions in collaboration with universities or research institutes, and the number of patent inventions by enterprises at a 1% confidence level. The study also conducts robustness tests through placebo tests and replacement of propensity score matching. Based on the research results, the article further analyzes and verifies the heterogeneous impact of the strategic emerging industry policy based on corporate property rights, asset size, and location. In addition, the study verifies the impact of basic research at different levels on corporate performance, and the results show that only applied basic research can significantly improve the asset return on investment, while theoretical basic research and collaborative basic research do not have a significant impact on asset return on investment in the short term. The theoretical analysis and empirical tests both demonstrate that strategic emerging industries have a significant promoting effect on basic research of enterprise, and that the effect varies based on the enterprise's property rights, asset scale, and geographic location. The paper also confirms that basic research at different levels of enterprises will have different impacts on enterprise performance. Based on these research conclusions, this paper provides new perspectives for future exploration of enterprise basic research, and offers important management insights for enterprises to develop their own basic research strategies and for the government to formulate industrial policies. Enterprises should continue to increase investment in basic research, promote the integration of industry, university and research, and choose the basic research model suitable for enterprises themselves. For the government, it should further increase the support for enterprise basic research and optimize the relevant policy content.
