郑州都市圈创新联系与驱动机理研究

Research on Innovation Connection and Driving Mechanism of Zhengzhou Metropolitan Area

以郑州都市圈为研究对象,从知识创新、技术创新、服务支撑三方面构建郑州都市圈创新评价体系,使用引力模型测算郑州都市圈创新联系强度并探讨郑州都市圈创新联系的驱动机理。研究结果表明,2017—2022年,郑州都市圈内各城市的创新能力不断提升但是增速存在差异,郑州市为创新核心,洛阳市、新乡市与焦作市是次核心,济源市的创新能力增长速度最快,由边缘城市上升到创新次核心地位。郑州都市圈各城市创新联系强度不仅受距离影响,还受各节点城市创新能力强弱的制约,总体上同城化程度不高,未达到成熟状态。地理邻近、认知邻近、制度邻近与创新网络结构是推动郑州都市圈创新联系不断增强的重要力量。

Through taking Zhengzhou metropolitan area as the research object,the study constructs the innovation evaluation system of Zhengzhou metropolitan area from three aspects:knowledge innovation,technology innovation and service support,uses gravity model to estimate the innovation linkage strength of Zhengzhou metropolitan area,and discusses the driving mechanism of innovation linkage of Zhengzhou metropolitan area.The results show that the innovation capability of the cities in Zhengzhou metropolitan area constantly improves from 2017 to 2022,but the growth rate is different.Zhengzhou City is the innovation core.Luoyang City,Xinxiang City and Jiaozuo City are the second core.Innovation capability of Jiyuan City grow rapidly,rising from the edge city to the innovation core status.The innovation connection strength of the cities in Zhengzhou metropolitan area is not only affected by the distance,but also restricted by the innovation ability of each node city.On the whole,the degree of urbanization is not high and has not reached a mature state.Geographical proximity,cognitive proximity,institutional proximity and innovation network structure are the important forces to promote the continuous enhancement of innovation links in Zhengzhou metropolitan area.
