成渝地区双城经济圈产学合作对高校创新绩效的影响研究——基于高校研发投入的中介效应分析

Research on the Influence of Industry-university Cooperation on University Innovation Performance in Chengdu-Chongqing Twin-City Economic Circle:An Analysis of Intermediary Effect Based on R&D Investment in Colleges and Universities

高校创新绩效的产出是成渝地区双城经济圈发展的有效动力,受到产学合作和研发投入等因素的影响。收集2005—2018年重庆市和四川省有关研发投入、产学合作和创新绩效的指标数据,进行回归分析发现:成渝地区双城经济圈的产学合作对高校创新绩效产生显著的正向作用;成渝地区双城经济圈高校的研发投入在产学合作对创新绩效的影响中发挥中介效应,产学合作对高校研发投入产生显著的正向作用,高校研发投入对高校创新绩效产生显著的正向作用;政府支持力度在高校产学合作影响研发投入中产生显著的正向调节作用,而在研发投入影响创新绩效中产生微弱的正向作用。应推动成渝地区双城经济圈的产学合作进程,发挥高校、企业与政府间一体化的协同创新效应。适度增加高校研发投入,减少政府干预,激发高校科研创新活力。

The output of innovation performance of colleges and universities is the effective driving force for the economic development of the two cities in Chengdu-Chongqing region,which is affected by the factors such as industry-university cooperation and R&D investment.By collecting the relevant indicators of R&D investment,the industry-university cooperation and innovation performance between Chongqing and Sichuan from 2005 to 2018,the regression analysis shows that:firstly,the cooperation between industry and university in the Chengdu-Chongqing Twin-city Economic Circle has a significant positive effect on the innovation performance of universities;secondly,the research and development investment of universities in the Chengdu-Chongqing Twin-city Economic Circle plays a mediating role in the impact of industry-university cooperation on the innovation performance,while the industry-university cooperation has a significant positive effect on the research and development input of universities,and the research and development input has a significant positive effect on the innovation performance of universities;finally,the level of government support has a significant positive moderating effect on the impact of university-industry cooperation on R&D input,but has a weak positive effect on the impact of R&D input on innovation performance.It is necessary to deepen the cooperation between industry and education in Chengdu-Chongqing Twin-City Economic Circle,and bring into play the synergistic innovation effect of the integration of universities,enterprises and governments.The research and development investment in colleges and universities should be increased appropriately,government intervention to be reduced,and the vitality of scientific research and innovation in colleges and universities to be stimulated.
