政府的科技激励政策对大中型工业企业R&D投入及其专利产出的影响——上海市的实证研究

本文从动态角度运用面板数据分析中的随机效应模型实证研究了上海市政府的科技激励政策对大中型工业企业自筹的R&D投入及其专利产出的影响。本文认为 ,政府的科技拨款资助和税收减免这两个政策工具对大中型工业企业增加自筹的R&D投入都具有积极效果 ,并且政府的拨款资助越稳定效果越好 ;政府拨款资助和税收减免互为补充 ,提高一个的强度也会增加另一个的效果 ,但这个效应以政府税收减免为主。不同来源的R&D支出和不同等级的人力资源对专利产出的影响是不同的 ,自筹的R&D支出对专利产出有着显著的正面作用。

On The Impact of Government's S&T Incentive Policy on the R&D input and its patent output of large and medium-sized Industrial enterprises in Shanghai

This paper is an empirical research that studies the impact of government's Science & Technology (S&T) Incentive Policy on the R&D input and its patent output of large and medium-sized Industrial enterprises in Shanghai in views of dynamic. It adopts the random effect model based on panel data. The general finding is that both sponsoring and tax deduction have a positive effect on business R&D input, and the more stable in government's S&T sponsoring, the better effects on promoting Industrial enterprises increasing R&D input. However, the effects are different because of their different policy characteristics. Furthermore, we find that the business R&D input has a more direct and significant effect on the patent output in comparison to the effect of government's S&T sponsoring. This paper explores the differential effects of the R&D input based on various sources and degree of human capital intensity on patent, as an output of R&D.
