摘要
为破解区域中心城市创新生态圈创新力场强分布不均匀导致区域创新不平衡的问题,实现区域协同创新,基于断裂点模型、创新力场强模型和创新辐射力模型,对长三角城市群区域中心城市创新生态圈辐射效应进行实证研究。结果表明:长三角城市群创新力场强整体以“沪—苏—宁—合—杭—沪”为边界呈圆形网络分布,包括上海创新辐射带、苏州创新辐射带、杭州创新辐射圈、南京创新辐射带以及合肥创新辐射圈等五大核心辐射区;创新力场强分布不均匀,靠近核心辐射区的城市创新力场强密集,受到多重辐射效应影响,而边缘城市受到辐射效应微弱;周围城市创新要素量对创新力场强具有倍乘效应,可通过增加其创新要素量放大创新辐射效应。
In order to solve the problem of regional innovation imbalance caused by uneven distribution of innovation power field of regional central cities and realize regional collaborative innovation,an empirical study on the radiation effect of innovation ecosystem of regional central cities in Yangtze River Delta urban agglomeration was conducted based on the fracture point model,innovation force field model and innovation radiation force model.The results show that the innovation power field of the Yangtze River Delta urban agglomeration is distributed in a circular network with the boundary of"Shanghai Suzhou Nanjing Hefei Hangzhou Shanghai",including five core radiation areas:Shanghai innovation radiation zone,Suzhou innovation radiation zone,Hangzhou innovation radiation zone,Nanjing innovation radiation zone and Hefei innovation radiation zone;The distribution of innovation power field is uneven,and the innovation field near the core radiation area is dense,and it is affected by multiple radiation effects,while the radiation effect of marginal city is weak;The amount of innovation elements brought by the surrounding cities has a multiplier effect on the innovation field,and the radiation effect of innovation can be amplified by increasing the amount of innovation elements.
