Measurement of variables.

In the context of digital economy, both the process and boundaries of open innovation performance are changing, and digital transformation has become an important factor for enterprises to realize open innovation performance in a complex and changing environment. This study based on the dynamic capability theory, etc. to explore how digital transformation drives the open innovation performance of enterprises and analyze its impact effects as well as the internal mechanism of action. In this paper, A-share listed companies in China’s Shanghai and Shenzhen cities from 2008–2022 are selected as research samples for empirical tests, and the research results show that digital transformation significantly stimulates enterprises’ open innovation performance, which still holds true after relying on a series of robustness tests. The study on the mechanism of action shows that digital transformation mainly enhances the dynamic capability of digital innovation, and ultimately promotes the open innovation performance of enterprises. And environmental dynamics play a positive moderating role. Heterogeneity analysis shows that the incentive effect of digital transformation on open innovation performance is more obvious in enterprises with high-tech and non-state ownership. Based on the new perspective of digital innovation dynamic capability, this study further reveals the effect and mechanism of digital transformation on open innovation performance, and provides theoretical basis and decision-making reference for enterprises to utilize the opportunity of digitalization to achieve open innovation performance results.在数字经济背景下，开放式创新绩效的实现流程与边界均发生改变，而数字化转型已成为企业在复杂多变环境中实现开放式创新绩效的关键因素。本研究基于动态能力理论等分析框架，探究数字化转型对企业开放式创新绩效的驱动路径，并剖析其影响效应与内在作用机制。本文选取2008-2022年中国沪深A股上市公司作为实证检验的研究样本，研究结果表明，数字化转型可显著提升企业开放式创新绩效，该结论经一系列稳健性检验后依然成立。作用机制分析显示，数字化转型主要通过增强数字创新动态能力，最终推动企业开放式创新绩效提升；环境动态性发挥正向调节作用。异质性分析表明，数字化转型对开放式创新绩效的激励效应在高新技术企业与非国有控股企业中更为显著。本研究基于数字创新动态能力的全新视角，进一步揭示了数字化转型对企业开放式创新绩效的影响效应与作用机制，可为企业抢抓数字化机遇以实现开放式创新绩效目标提供理论依据与决策参考。
