以中国沪深两市物联网行业上市公司为样本,以企业全要素生产率(TFP)作为被解释变量,分别采用面板数据固定效应模型和横截面计量方法,实证检验了政府财税补贴、风险投资参与对企业生产效率的影响。结果表明:政府直接补贴和税收优惠并没有带来上市公司生产效率的提高,风险投资的参与对于物联网上市公司生产效率也没有显著的积极影响。最后,提出了相应建议。
This paper makes an analysis of tax preferences and subsidy and VC on operating performance using TFP as de- pendent variable with a sample of publicly - traded enterprises of Internet of Things in a balanced panel data and a set of sectional data. The result shows that tax preferences and direct subsidy had no statistically significance on the growth of pro- ductivity of the listed companies and VC has no significant effect on it too.
