G60科创走廊科技创新效率及其空间网络结构分析
Analysis of Technological Innovation Efficiency and Spatial Network Structure of G60 Science and Technology Innovation Corridor
摘要
Abstract
The super-efficiency SBM model was used to measure the innovation efficiency of cities in the G60 Science and Innovation Corridor from 2012 to 2021,and the spatial correlation network of innovation efficiency was constructed with the gravity model.The research findings were as follows:(1)In recent years,the S&T innovation efficiency has increased,the regional differences have gradually expanded,and the spatial correlation intensity showed a pattern of high in the east and low in the west.(2)Network density and network correlation gradually increased,network grade and network efficiency first decreased and then increased,and the overall fluctuation decreased;(3)Degree centrality and proximity centrality showed an upward trend,and the regional distribution was consistent.The highest values were concentrated in Hangzhou,Shanghai,Suzhou and other regions;The annual change of intermediary centrality was little,and the overall central region was high,while the east and west were low;(4)There were few connections between the eastern regions and the western regions.The network pattern of regional science and technology innovation efficiency still needed to be improved.The conclusions provide policy suggestions for improving regional innovation efficiency and promoting regional high-quality integrated development.关键词
