产业协同集聚、工业机器人应用与技术创新

Synergetic Agglomeration of Industries,the Application of Industrial Robots and Technological Innovation

本文运用2015—2019年中国30个地区的面板数据,讨论工业机器人应用对技术创新的影响,并基于面板门槛模型研究生产性服务业与制造业协同集聚对二者关系的门槛效应。研究发现:①工业机器人应用对技术创新具有显著促进作用,且这一影响在低劳动力成本地区显著,在中、高劳动力成本地区不显著;②产业协同集聚在工业机器人应用对技术创新的影响中存在单门槛效应,伴随产业协同集聚跨越门槛值,工业机器人应用对技术创新的影响由负转正;③针对生产性服务业细分行业与制造业的协同集聚,其中,批发、零售业,信息传输、软件和信息技术服务业,金融业及科学研究和技术服务业均存在单门槛效应,除科学研究和技术服务业中工业机器人应用系数由负转正外,其余行业均由不显著变为显著正向影响。未来中国要加速机器人全行业应用,以产业协同集聚推动产业融合发展,实现高水平科技自立自强。

Based on the panel data from 30 regions in China from 2015 to 2019,this paper discusses the impact of the application of industrial robots on technological innovation,and investigates the threshold effect of synergetic agglomeration of producer services and manufacturing on the impact using panel threshold model.The results show the followings.①The application of industrial robots has a significant contribution to technological innovation,and this effect is significant in the regions with low labor cost and not significant in the regions with medium and high labor cost.②There is a single threshold effect in the impact of the application of industrial robots on technological innovation when taking the synergetic agglomeration as threshold variable.Along with the value of the synergetic agglomeration crossing the threshold value,the impact of the application of industrial robots on technological innovation turns from negative to positive.③For the synergetic agglomeration of the segmented industries of producer services and manufacturing,there are single threshold effects in the industries of wholesale and retail trade,information transmission,software and information technology services,financial business and scientific research and technical services.The coefficient of the application of industrial robots in scientific research and technical services turns from negative to positive,and the remaining three industries all changed from insignificant to significant positive.In the future,China should accelerate the application of robots across all industries,and promote the development of industrial integration by enhancing synergetic agglomeration,to achieve sci-tech self-reliance and self-strengthening at higher levels.
