政府干预对新兴企业技术创新的影响研究--基于负二项式模型

摘要

The weak technological innovation capability of emerging enterprises seriously hampers their development , the market force alone is difficult to resolve this problem, then do they need government’s guidance and incentive? Aiming to solve this problem,this paper applies the panel factor analysis to measure the variable of government intervention,and em⁃ploys the negative binomial model to study the impact of government intervention on emerging enterprise technological innova⁃tion. The results show that: Government intervention and technological innovation have an inverted U-shaped relationship;Government intervention has a significant impact on promoting incremental innovation in early period,however,the inter⁃vention inhibits the innovation when it exceeds the optimal value;Government intervention inhibits breakthrough innovation in the early period,however,the intervention is conducive to promoting the innovation when it reaches a certain degree.%新兴企业技术创新能力弱的问题严重制约其发展，仅凭市场力量难以解决，此时是否需要政府引导和激励？针对此问题，文章利用面板因子分析法对政府干预变量进行量化测度；利用负二项式模型，研究政府干预对新兴企业技术创新的影响。结果表明：政府干预与技术创新呈倒U型关系；政府干预对于渐进式创新初期具有显著性促进作用，当干预超过最优值时，反而抑制其创新；对突破式创新初期具有抑制作用，当干预达到一定程度，有助于促进其增加。
