Using China's Strategic Emerging Industries Classification (CSEIC), which is enacted in 2018, as a quasi-natural experiment, this study investigates its impact on corporate innovation behaviors. In basic research, we find that: (1) The CSEIC significantly enhances both substantive and strategic innovation; (2) The effect of CSEIC is influenced by the characteristics of the enterprise. Specifically, in state-owned enterprises (SOEs), the CSEIC significantly enhances substantive innovation and strategic innovation, while in non-SOEs, the CSEIC only significantly enhances substantive innovation. In further research based on entrepreneurial spirit, we find that: (1) The effect of CSEIC on strategic innovation is suppressed if entrepreneurial patriotism is higher, no matter whether the enterprise is SOEs or non-SOEs; (2) The effect of CSEIC on substantive innovation is enhanced, if and only if entrepreneurial integrity is higher in SOEs or International Vision is higher in non-SOEs. These findings offer valuable insights for policymakers aiming to foster innovation through targeted support for enterprise leaders, highlighting the need for tailored approaches considering the distinct characteristics of SOEs and non-SOEs.
