异质性企业与基础研究决策

Heterogeneous Firms and Basic Research Investment

针对中国企业基础研究投入严重不足的现实困境,提出一个基于异质性企业分析框架的决策模型,分析了生产率异质性对于企业基础研究投入的影响。模型发现,生产率越高,企业对于创新越积极,但是只有生产率足够高的企业才会选择开展基础研究。而基础研究收益的增加或者相关成本的降低会促使更多的企业投入基础研究,针对中国工业行业面板数据的实证检验证实了这一点。研究还发现,良好的盈利能力、适当的企业规模以及优化的人力资本结构都会对企业产生正向的激励作用。提高中国企业基础研究的规模和水平,要求建立更加公平和规范的市场,加强对知识产权的保护以及科学家的培养,理顺相关体制和机制,推动人才和其他科研资源在高校、科研机构与企业间更加顺畅地流动。

According to Chinese firms investment shortage in the basic research,we build a decision-making model based on enterprise heterogeneity to analyze the impact of productivity heterogeneity on the firm investment of basic research.We find that the higher a firm s productivity is,the more active the firm invest in innovation,yet only when the productivity is high enough,the firm would choose the basic research.Using a panel data of Chinese industries,we further confirm that any increase in the return or any decrease in the cost of basic research would encourage firms to do basic research.Empirical studies also suggest that good profitability,appropriate firm size and optimized human capital structure might prompt investment in basic research.To promote Chinese basic research requires to establish a more fair and regulated market,to strengthen the protection for intellectual property and the training of scientists,to straighten the relevant institutions and mechanisms,and to make various innovative resources flow more smoothly among universities,research institutions and enterprises.
