摘要
扩大技术市场规模对提升农业科技创新质量具有重要作用.以2004-2020年为研究时段,利用机器学习与文本分析方法,测算各省(市、自治区)农业科技创新质量;在此基础上,实证分析技术市场规模对农业科技创新质量的影响效应,通过构建中介效应模型揭示了技术市场规模影响农业科技创新质量的作用机制.研究发现:技术市场规模对农业科技创新质量具有显著的正向影响,且这一影响在中部和东部地区较强,而在西部地区则相对较弱;技术市场规模通过知识溢出和协同创新效应,正向促进农业科技创新质量提高;其中,知识溢出的中介效应强于协同创新.研究结论为进一步厘清技术市场规模影响农业科技创新质量的作用机理提供了经验证据,也为如何提升农业科技创新质量提供了新视角与新路径.
Abstract
Expanding the scale of the technology market plays an important role in improving the quality of agricultural technical innovation.It took the period from 2004 to 2020 as the research period,and used machine learning and text analysis methods to calculate the quality of agricultural technical innovation in various provinces(cities,autonomous regions).On this basis,empirical analysis was conducted to examine the effect of technology market scale on the quality of agricultural technical innovation,and a mediation effect model was constructed to figure out its internal transmission mechanism.The results show that technology market scale has a significant positive influence on the quality of agricultural technical innovation,and such influence is stronger in the central and eastern regions,while relatively weaker in the western regions.Technology market scale positively encourages the improvement of the quality of agricultural technical innovation through knowledge spillover and collaborative innovation effects.The mediating effect of knowledge spillover is stronger than collaborative innovation.The research conclusion provides empirical evidence for further clarifying the mechanism by which technology market scale affects the quality of agricultural technical innovation,and provides a new perspective and path for improving the quality of agricultural technical innovation.
