政府补助时序模式抉择——高新技术行业政府补助、R&D投资与绩效的中介效应

The Timing Mode Selection of Government Subsidies——Based on the Mediating Effect Analysis of Government Subsidy,R&D Investment and Enterprise Performance of Hi-Tech Industry

对中国2007—2014年516家高新技术上市公司面板数据进行时序分组发现,政府补助均能通过R&D投资对企业绩效产生正向中介效应。其中,在"事中补助"模式中本期补助经本期R&D投入对本期企业绩效的总效用最优,但中介效应较差;上期补助经上期R&D投入对本期企业绩效的总效用稍差,但中介效用最优,因此最符合政府补助的政策导向初衷;而"事前补助"模式总效用和中介效用较差。结论有效论证和解决了政府补助时序模式抉择的争议,也为政府补助模式选择和政策倾向提供了决策参考。

This paper makes an empirical study on the panel data of 516 hsted high-tech compames Irom, wnne the data were grouped by panel data. Though the study we find that the government subsidies have positive mediating effect on hi-tech industry but the effect is affected the time selection. The study indicates that within three different timing model： subsidy advance, subsidy underway and subsidy afterwards, subsidy underway has best total effect and relatively poor mediating effect in the model the subsidy prior period though R＆D expend is good for current period enterprise per- formance and has maximum mediating effect. Meanwhile, subsidy advance model is not so good for total effect as well as mediating effect. Our research conclusion has effective settled the to the government subsidy timing decision making. problem of government subsidy timing, and contributed
