【摘要】 高新科技企业关系到民生,更维系着本国的经济增长。高新技术行业的特点主要为投入资金较高、密集人才水平较高、创新能力较高、企业风险较高等。至今,我国仍对整个行业制定了 15%的所得税率以鼓励高新技术企业增加研发投入。但是市场上也确实存在对政府补贴使用不合理,甚至假借高新技术的名号,依靠政府补贴经营的企业。因此,研究政府补贴与企业绩效水平之间的关系具有理论与现实意义。本文以我国创业板于2017年至2019年的606家上市的高科技领域相关企业作为研究分析的样本,进行数据分析,构建固定效应模型,探究政府补贴政策实行的效果,以及不同补贴政策的影响结果,通过多元回归的方式对影响企业综合绩效水平的因素进行实证研究,并得出研究结论:政府补助和税收优惠都对企业综合绩效水平产生正向影响,研发投入对企业绩效水平也产生了正向作用;但是税收优惠的影响效果更显著,并且研发投入在其中起到中介作用;税收优惠对于企业绩效的影响存在滞后性,并且对于滞后一期的影响程度高于当期的影响。最后,在实证研究结果的基础上,分别针对国家相关政策方面和行业内企业层面提出了相关对策和建议。政府应当提升监管水平,完善补助制度,优化优惠体系。高新技术企业应努力提高资金的投入与产出比,完善内部监督管理制度,科学规划研究方案,有效管理研发活动。更多还原

【Abstract】 High-tech companies are related to persons’ livelihood and the growth of our economy.The high-tech industry is characterized by high investment,high density of high-level talents,high innovation and high risk,etc.At present,China still applies 15%income tax rate to the whole industry to encourage high-tech enterprises to increase investment in R&D.However,there are some enterprises that use government subsidies unreasonably in the market,even though they rely on government subsidies in the name of high technology.Therefore,studying the relationship between government subsidies and corporate performance has important theoretical and practical significance.This article uses the 606 high-tech companies listed on China’s Second-board from 2017 to 2019 as the research and analysis samples,carries out data analysis,constructs a fixed-effect model,and explores the effect of government subsidy policies and the impact of different subsidy policies As a result,the empirical research on the factors that affect the comprehensive performance of the company was conducted through multiple regressions,and the conclusions were drawn:government subsidies and tax incentives both have a positive impact on the comprehensive performance of the company,and R&D capabilities also have a role Positive effect;but the impact of tax incentives is more significant,and R&D capabilities play an intermediary role;the impact of tax incentives on corporate performance is lagging,and the impact on the lag period is higher than the impact of the current period.Finally,on the basis of the empirical research results,relevant countermeasures and suggestions were put forward for the relevant national policies and the enterprise level in the industry.The government should improve the level of supervision,improve the subsidy system,and optimize the preferential system.High-tech enterprises should strive to increase the ratio of capital input to output,improve the internal supervision and management system,scientifically plan research programs,and effectively manage R&D activities.更多还原
