摘要
本文运用中国工业面板数据,实证研究了企业规模、产权结构等因素对R&D投入的影响。研究发现,企业销售收入对R&D支出有显著正影响,企业员工数量对R&D支出和R&D人数均没有显著影响,这意味着熊彼特假说依赖于企业规模和创新变量的设定;国有产权对R&D人数有显著正影响,但对R&D支出没有显著影响,这可能表明国有企业在R&D资源配置上存在着某种扭曲。研究还发现,政府资助对激励企业R&D投入有重要作用。
The paper investigates the effects of firm size and ownership on R＆D inputs by using the panel data on Chinese industry. The paper finds that sales revenue has significantly positive effects on R＆D expenditures and the number of employees has no significant effects on both R＆D expenditures and R＆D employees. The paper also finds that state ownership has significantly positive effects on R＆D employees and no significant effects on R＆D expenditures. The important role of government subsidy in stimulating R＆D inputs is also found in this paper.
