异质性产学研协同创新对地区全要素生产率的非对称效应

symmetric Effects of Heterogeneous Collaborative Innovation of Industry-university-research on the Total Factor Productivity

摘要:

探明不同产学研协同创新模式对地区全要素生产率的影响能为提升经济发展质量带来有益启示。区分全要素生产率与全要素生产率增长率，通过分析产学研协同创新与二者间作用关系，在运用信息熵测算中国30个省市产学研三边及产学、产研和学研双边协同创新水平基础上，检验各协同创新模式对地区全要素生产率及其增长率的影响。结果显示：产学研协同创新对全要素生产率存在模式非对称效应，产学和学研两种双边协同创新有递增的促进作用，产学研三边协同创新有递减的抑制作用，产研双边协同创新影响不显著，且仅产学双边协同创新既能改善技术效率又能推动技术进步，其他协同创新模式仅发挥了改善技术效率作用；产学研协同创新对全要素生产率存在地区非对称效应，促进作用在中西部地区更显著，且以改善技术效率为主；考虑滞后期检验发现学研双边协同创新更能为地区全要素生产率提升提供长久动力。

Abstract:

Exploring the impact of different modes of collaborative innovation among industry, university and research on the development of total factor productivity can provide useful insights for promoting the deep integration of industry, university and research and improving the quality of economic development. This paper distinguishes the total factor productivity from its growth rate, and analyzes the relationship between collaborative innovation of industry-university-research, and the total factor productivity and its growth rate, on the basis of using information entropy to measure the level of collaborative innovation among industry, university and research in 30 provinces and cities of China from 2009 to 2019, this paper examines the impact of collaborative innovation models of industry, university and research on total factor productivity and its growth rate, which can reveal the asymmetric effect of heterogeneous collaborative innovation of industry-university-research on the quality of regional economic development. The results show that:The impact of heterogeneous collaborative innovation of industry-university- research on the total factor productivity is asymmetric. The bilateral collaborative innovation of industry-university and university-research has an increasing promoting effect, while the trilateral collaborative innovation of industry-university-research has a decreasing inhibiting effect, in the channel of influence, only the industry-university bilateral cooperative innovation can improve the technical efficiency and promote the technical progress, and other cooperative innovation models can not promote the technical progress;The impact of heterogeneous collaborative innovation on total factor productivity is asymmetric among regions, and the promotion effect is more obvious in the central and western regions, but the main effect is to improve technical efficiency;The lag period test is considered and find collaborative innovation between academics and research institutes in both sample and the central and western regions will continue to drive the next stage of technological progress, which can provide long-term impetus for the upgrading of total factor productivity and the quality of regional economic development.
