摘　　要：基于我国28个省份2010—2020年省级面板数据,应用面板门槛模型验证政府补贴对高技术产业创新效率的影响是否随企业规模质量水平而变化,并将28个省份划分为东部和中西部两大区域,以此来比较分析这种影响的地域异质性。研究结果表明,政府补贴对高技术产业创新效率的作用效果具有显著的门槛效应,并且这种门槛效应具有一定的地域差异性;在不同企业规模质量区间内,政府补贴对高技术产业创新效率的影响效果不同,其中对28个省份高技术产业创新效率起到了显著的正向影响作用,但随着企业规模质量阈值的提高作用效果递减;对东部省份的影响效果呈现出先促进后抑制的非线性特征;对于中西部省份高技术产业创新效率有显著的促进作用,但呈现出先增强后减弱的倒“U”型特征。因此,政府应针对在不同地区的不同规模的企业实施差异化、动态化的补贴策略。Based on the panel data of China’s 28 provinces from 2010 to 2020, the panel threshold model is used to verify whether the impact of government subsidies on the innovation efficiency of high-tech industries changes with the scale quality of enterprises;the 28 provinces are divided into the eastern region, and the central and western region,in order to compare and analyse the regional heterogeneity of this influence. The research results show that government subsidies have a significant threshold effect on the innovation efficiency of high-tech industries, and this threshold effect has certain regional differences;In the range of enterprise scale and quality, the effect of government subsidies on the innovation efficiency of high-tech industries is different. Among them, government subsidies have a significant positive effect on the innovation efficiency of high-tech industries across the 28 provinces, but the effect decreases with the increase of enterprise scale and quality threshold;the impact on the eastern provinces shows a nonlinear characteristic of first promoting and then inhibiting;it has a significant promoting effect on the innovation efficiency of high-tech industries in the central and western provinces, but it shows an inverted "U" characteristic of first strengthening and then weakening. Therefore, government should implement differentiated and dynamic subsidy strategies for enterprises of different sizes in different regions.
