How and when does digital transformation promote technological innovation performance? A study of Chinese high-tech firms
基于中国19个高科技行业2010-2021年面板数据，研究发现数字化转型通过缓解内部信息不对称和调整研发投入，提升了技术创新的数量、质量和效率，但对亏损企业效果不显著。
Digital transformation and technological innovations are crucial responses of firms to external competitive dynamics; however, the complex relationship between them remains underexplored and contentious. Drawing on the dynamic capability view, we postulate that digital transformation influences technological innovations by alleviating internal information asymmetry and altering organizational resource distribution, thereby addressing routine and resource rigidities in the transformation process. To further explore the potential crowding-out effect of digital transformation on technological innovation, we designed a set of heterogeneity analyses based on contextual conditions surrounding resources accessible to firms. We examined these relationships using double fixed-effects and mediation models, based on a comprehensive panel dataset of 19 high-tech industries in China, spanning the years 2010–2021. Our results indicate that digital transformation promotes the quantity, quality, and efficiency of technological innovations, with a comparatively greater influence on the former two. These effects are mediated by internal information asymmetry and R&D intensity. Furthermore, the positive and significant effect of digital transformation is evident among firms located in the Eastern region of China and those that are profitable, but becomes negligible among loss-making firms. We conducted a series of robustness checks to validate the results and discussed their theoretical and practical implications.
