Abstract: As a cutting-edge technology industry, the high-tech industryis confronted with such a question as how can it achieve its high-quality development and improve its resilience in the face of external shocks, which has become a hotspotfor present researches. Based on provincial panel data from 2011 to 2019, this paper makes a calculation to obtain the numerical values of digital economy, business environment and high-tech industry resilience with the entropy method. Then based onthe theoretical analysis, it empirically tests the impact effect of digital economy on the resilience of high-tech industry, the impact mechanism and the adjustment effect of business environment with the econometric model. The results show that, the digital economy has a positive impact on the resilience of high-tech industries on the whole, and a good business environment can enhance the promotion of the digital economy on the resilience of high-tech industries. The heterogeneity test shows that the promotion effect of digital economy on industrial resilience varies from region to region, and the spillover effect on the eastern region is greater. The result of further impact mechanism test shows that the digital economy will promote the resilience of high-tech industries by promoting industrial upgrading and improving industrial innovation capacity.

Key words: digital economy, business environment, high-tech industry, resilience
