摘　　要：以2010—2019年沪深A股关键战略材料企业为研究对象,运用负二项回归方法检验政府研发补贴对关键战略材料企业实质性创新的影响效应,对比中央与地方政府研发补贴影响效应的差异,并进一步探索地方政府研发补贴影响效应的边界条件。研究发现,地方政府研发补贴对关键战略材料企业实质性创新有先抑后扬的“U型”激励效应,调节机制检验发现,区域市场环境与创新环境负向调节地方政府研发补贴的创新激励效应,且地方政府研发补贴的“U型”效应仅在国有企业与低发展水平城市企业出现。研究结论为地方政府合理制定研发补贴政策,促进关键战略材料企业实质性创新,加快核心技术国产化替代提供参考。This paper examines the effect of government R&D subsidies on the substantive innovation of critical strategic materials firms using negative binomial regressions,comparing the differential effect of the impact of central and local government R&D subsidies,using SSE and SZSE A-share critical strategic materials firms from 2010 to 2019 as the research Subjects.And further explored the boundary conditions of the impact effect of local government R&D subsidies.It is found that local government R&D subsidies have a significant"first depressing and then increasing"U-shaped effect on substantive innovation of critical strategic materials enterprises.Tests for moderating effects finds that the regional market environment and innovation environment negatively moderate the relationship between local government R&D subsidies and substantive innovation.The heterogeneity test finds that the U-shaped efect exists only in the sample of state-owned enterprises and low-development urban enterprises.The findings of the study provide some policy insights for local governments to reasonably formulate R&D subsidy policies to promote critical strategic material enterprises to implement substantive innovation and accelerate the localization of core technology substitution.
