企业所有制类型和企业规模的不同可能会导致政府科技资助对企业R&D产出的影响不同。基于所有制和企业规模相组合的异质性视角,理论上探讨了政府科技资助对企业R&D产出影响的权变效应,并采用上海市企业的面板数据,运用负二项回归的固定效应模型进行了实证检验。研究发现,就上海市而言,政府科技资助能够有效的促进企业R&D产出,且对于小微型非国有企业的促进最为显著,而对大中型国有企业R&D产出则存在微小的抑制作用。
The difference between the type of enterprise ownership and the size of the enterprise may lead to different effects of government technology funding on the output of the enterprise R & D. Based on the heterogeneous perspective of the combination of ownership and firm size, this paper theoretically explores the contingency effect of government science and technology funding on firm R & D output. Using the panel data of Shanghai firms, we use the fixed-effects model of negative binomial regression Empirical test. The study shows that in Shanghai, government subsidies for science and technology can effectively promote the R & D output of enterprises, and promote the promotion of small and non-state-owned enterprises most prominently. However, it has a slight inhibitory effect on R & D output of large and medium-sized state-owned enterprises.
