Can increasing technological complexity help strengthen regional economic resilience?

Improving regional economic resilience through technological innovation has always been a strategic focus of China, but the previous studies have paid little attention to the impact of structural characteristics of technological innovation on regional economic resilience. Based on the complexity of technology, this study studies the impact and mechanism of technological systems with more complex internal mechanisms on economic resilience. The main findings are as follows: (1) Higher technological complexity is conducive to technological innovation and can improve regional economic resilience; (2) technological complexity needs to be in the appropriate range, and its positive effect shows diminishing marginal effect; and (3) optimizing market competition and absorptive capacity plays a positive role in regulating the relationship between technological complexity and regional economic resilience. This study provides policy implications for implementing innovation-driven development strategy, formulating economic recovery plan, and medium- and long-term sustainable development strategy.
