制造业数字化转型与企业创新绩效OA北大核心CHSSCDCSSCICSTPCD

This paper takes China's A-share manufacturing listed companies from 2011 to 2021 as research samples to em-pirically investigate the impact of digital transformation of manufacturing enterprises on innovation performance and its mecha-nism.It is found that the digital transformation of manufacturing enterprises can help improve innovation performance,and it is still robust after a series of robustness tests and endogenous processing.The mechanism test results show that the digital transfor-mation of manufacturing enterprises can promote the improvement of innovation performance not only by improving corporate so-cial responsibility performance,but also by promoting the implementation of differentiation strategy.The mediation path of cost leadership strategy is not valid.The results of heterogeneity analysis show that the digital transformation of manufacturing enter-prises can improve their innovation performance significantly only in the eastern region of China.The industries in more fierce market competition have a greater effect on the improvement of innovation performance,and the manufacturing enterprises recog-nized as high-tech enterprises have a more significant impact on innovation performance.The digital transformation of state-owned manufacturing enterprises can not significantly improve their innovation performance.
