Research on the Influence of Technology Blockade on the Technology Innovation Level of Manufacturing Enterprises
Based on the listed manufacturing enterprises from 2012 to 2021 as the research object,text min-ing method was used to construct the index of technology blockade degree.The Difference-in-Difference model and the Moderation-Effect model were used to analyze the effect and mechanism between technology blockade and the level of enterprise technology innovation from the perspectives of enterprise,government and market.The heterogeneity analysis was carried out.The research results show that technology block-ade promotes enterprise technology innovation.Restraining managerial myopia,increasing policy support and easing financing constraints have a positive moderating effect,and the improvement of enterprises'technology innovation level can weaken the market blockade effect of the trade war on enterprises.Expan-ding the scale of enterprises and improving the digitalization degree of enterprises can promote enterprise technology innovation more effectively.
