【摘要】:本文基于软件与信息企业的微观截面数据,应用Tobit模型,检验了研发投入与企业规模、所有制类型及政府补贴等因素的关系。研究发现,研发投入与企业规模存在U型关系,国有企业同其他类型企业相比,在研发投入上未表现出显著差异,企业年龄、企业利润率与研发投入具有显著的负向关系,政府补贴有利于企业研发投入,出口、资本密集度对企业研发投入无显著性影响。
[Abstract]:Based on the microcosmic cross-section data of software and information enterprises, this paper tests the relationship between R & D investment and enterprise size, ownership type and government subsidy by using Tobit model.It is found that R & D investment has a U-shaped relationship with enterprise scale, and there is no significant difference in R & D investment between state-owned enterprises and other types of enterprises, and there is a significant negative relationship between R & D investment and enterprise age, profit margin and R & D investment.Government subsidy is beneficial to enterprise R & D investment, while export and capital intensity have no significant influence on R D investment.
