广西政府科技投入对企业R&D投入的影响效应分析

Impact of Government Science Technology Input on R&D Input of Industrial Enterprises in Guangxi

文章采用2006—2015年广西大中型工业企业组成的行业面板数据,估计了广西政府科技投入对企业R&D投入的影响。结果表明,政府对企业的科技投入短期内对企业自身R&D投入具有较强的挤入效应,但长期激励机制还没有完全形成;政府科技投入效果受到政府资助稳定性和资助力度的影响,政府资助越稳定其资助效果越好,资助率在6%—10%时政府科技投入的效果最好。

This paper estimates the impact of government science technology （S＆T） input on the R＆D input of enterprises by applying Guangxi, s large and medium - sized industrial enterprises panel data from 2006 to 2015. The results show that government S＆T input has strong crowding - in effect on firms ’ R＆D input in short term,but long - term incentive mechanism is still not fully formed. The effect of subsidy is affected by it’ s stability and intensity. Besides,the more stable the government S＆T subsidy is,the better subsidizing effect it will get. The effect is best while the government S＆T subsidizing rate is 6% ？10%.
