本文選題：研發(fā)投入　切入點：企業(yè)規(guī)模　出處：《科研管理》2017年09期

【摘要】：本文基于軟件與信息企業(yè)的微觀截面數(shù)據(jù),應用Tobit模型,檢驗了研發(fā)投入與企業(yè)規(guī)模、所有制類型及政府補貼等因素的關(guān)系。研究發(fā)現(xiàn),研發(fā)投入與企業(yè)規(guī)模存在U型關(guān)系,國有企業(yè)同其他類型企業(yè)相比,在研發(fā)投入上未表現(xiàn)出顯著差異,企業(yè)年齡、企業(yè)利潤率與研發(fā)投入具有顯著的負向關(guān)系,政府補貼有利于企業(yè)研發(fā)投入,出口、資本密集度對企業(yè)研發(fā)投入無顯著性影響。
[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.
