实体企业进行数字化转型不仅能够释放企业内部的数字化生产力，推进产业数字化进程，还有助于整合创新资源，加速创新进程。文章基于2011—2020年我国沪深A股上市公司数据，实证检验了企业数字化水平提升对企业创新的影响。研究结果表明：企业数字化水平提升显著提高了企业的创新能力；企业数字化水平提升带来的创新产出存在滞后性；企业数字化水平提升对企业创新能力的促进效应在不同规模、不同产权、不同地区的企业之间存在异质性，大规模企业、非国有企业及东部地区企业在数字化进程中表现出了更为显著的创新增长。基于此，今后应进一步完善数字化政策，鼓励企业加速数字化进程，根据企业异质性制定差异化的激励扶持政策，完善政策外部环境和配套体系。

The digital transformation of entity enterprises not only unleashes the digital productivity within the enterprise, advancing the digitalization of the industry, but also helps integrate innovative resources and accelerate the innovation process. Based on the data of A-share listed companies in Shanghai and Shenzhen from 2011 to 2020, this paper empirically tested the impact of the enhancement of enterprise digitalization level on enterprise innovation. The research results show that the enhancement of enterprise digitalization level significantly and positively affects enterprise innovation, and there is a lag in the increase of innovation output brought by the enhancement of digitalization level. And this promotion effect is heterogeneous among enterprises of different sizes, different property rights and different regions, with large-scale enterprises, non-state enterprises and enterprises in the eastern region showing more significant innovation growth in the digitization process. Based on this, it is of necissity to further promote the improvement of relevant digitization policies to encourage enterprises to accelerate the digitization process, formulate differentiated encouragement and support policies according to heterogeneous enterprises and enhance the establishment of relevant supporting policy systems.
