摘　　要：使用中国2001-2019年省际面板数据,首先就贸易开放、收入差距对区域创新能力的影响机制进行分析。在此基础上,建立以收入差距为门槛变量的门槛效应模型,就贸易开放对以创新产出、创新效率为主要衡量指标的区域创新能力的作用机制进行了实证分析。结果表明:贸易开放对区域创新产出存在单门槛效应,对区域创新效率则存在显著的双门槛效应,即当收入差距低于某一临界值时,贸易开放会促进区域创新能力提升;当收入差距高于某一临界值时,贸易开放将对区域创新能力提升产生抑制作用。稳健性检验证实了相关结论。进一步的研究表明,在既定收入差距下,进口贸易对区域创新效率的改善更为明显,而出口贸易则更有利于提高区域的创新产出。Given China’s inter provincial panel data from 2001 to 2019,this paper first analyzes the impact mechanism of trade openness and income gap on regional innovation capability.On this basis,this paper establishes a threshold effect model with income gap as the threshold variable,and makes an empirical analysis on the mechanism of trade openness on regional innovation capability with innovation output and innovation efficiency as the main content.The results show that:trade openness has a single threshold effect on regional innovation output and a significant double threshold effect on regional innovation efficiency,that is,when the income gap is lower than a certain critical value,trade openness will promote the improvement of regional innovation ability;when the income gap is higher than a certain critical value,trade openness will inhibit the construction of regional innovation ability.The robustness test confirmed the relevant conclusions.Further research shows that under the given income gap,import trade improves regional innovation efficiency more obviously,while export trade is more conducive to improving regional innovation output.
