摘要
基于2013~2017年我国沪深A股上市公司的研究样本,本文运用聚类分析的方法,以生产要素密集度的分类视角,将选取的样本公司归类为劳动密集型、资本密集型和技术密集型三个行业,运用混合OLS回归分析的方法,对比考察不同行业财政补贴对自主创新的影响。使用专利授权数量来衡量企业创新,系统检验了财政补贴的专利产出效应。研究表明,财政补贴与专利产出之间存在着显著的正相关关系,并且财政补贴对高质量发明专利的影响高于其他专利;财政补贴对专利产出的正向激励作用呈现出劳动密集型行业、资本密集型行业和技术密集型行业依次递增的结果;金融杠杆对自主创新的作用却表现出对技术密集型行业显著促进作用,而对劳动密集型行业和资本密集型行业具有显著的抑制作用。
Based on the research sample of China’s Shanghai and Shenzhen A-share listed companies from 2013 to 2017, this paper uses cluster analysis to classify the selected sample companies as la-bor-intensive, capital-intensive, and technology from the perspective of the classification of pro-duction factor intensity. In the intensive three industries, the method of mixed OLS regression analysis was used to compare and examine the impact of financial subsidies of different industries on independent innovation. The number of patent grants is used to measure enterprise innovation, and the patent output effect of financial subsidies is systematically tested. Research shows that there is a significant positive correlation between financial subsidies and patent output, and the impact of financial subsidies on high-quality invention patents is higher than other patents;the positive incentive effect of financial subsidies on patent output is labor-intensive industry, capital-intensive industry, and technology-intensive industry in increasing order;the effect of financial leverage on independent innovation has shown a significant promotion of technology-intensive industries, but a significant suppression of labor-intensive and capital-intensive industries effect.
