摘要
创新产出是衡量政府研发补贴有效性的重要指标。本文以2014—2019年中国沪、深A股上市企业为研究样本,利用倾向得分匹配模型考察了政府研发补贴对企业创新产出的影响。研究发现:政府研发补贴推动了企业创新产出量质齐升,但其质量提升效应不及数量推动效应;政府研发补贴一定程度上诱发了民营企业、高竞争程度行业和市场化环境较差地区企业的策略性创新行为;政府研发补贴的持续性是提升企业创新质量的关键路径。据此,本文提出:政府要进一步优化研发补贴政策设计,重视知识产权保护,深入推进营商环境优化,为企业高质量发展构筑良好的创新生态环境。
Innovation output is an important indicator to measure the effectiveness of government R&D subsidies.This article uses the Shanghai and Shenzhen A-share listed enterprises from 2014 to 2019 as a research sample to investigate the impact of government R&D subsidies on enterprise innovation output by propensity score matching model.The study shows that,government R&D subsidies promote the improvement of both quantity and quality of enterprise innovation output,but the quality improvement effect is not as good as the quantity promotion effect;to a certain extent,government R&D subsidies have induced strategic innovation behavior among private enterprises,high-competitive industries and enterprises in regions with poor marketization environment;the sustainability of government R&D subsidies is the key way to improve the quality of enterprises innovation.Accordingly,this article proposes that the government should further optimize the design of R&D subsidy policies,pay attention to intellectual property protection,further promote the optimization of the business environment,and build a good innovation ecological environment for the high-quality development of enterprises.
