Abstract

Abstract: Technical innovation is a key factor in boosting regional economic resilience. This paper, uses patent data measurement technically-related diversity and non-related diversity to construct urban technical network, applies anti-reality function to measure regional economic resilience, and employs multiple linear regression model to discuss impacting mechanism of technical diversity and technical network structure on regional economic resilience in 41 prefectures in Yangtze River delta area. Technical related diversity level, non-related diversity level in Yangtze River delta area show an overall rising trend, but imbalanced in spatiotemporal distribution, urban technical network topological structures (density, average agglomerating coefficient, average path length) vary largely, technical innovation turns to physical communication from traditional metallurgy. Spatiotemporal distribution of economical resilience intensity in Yangtze River delta area is uneven, low-in-east-high-in-west, and low-in-south-high-in-north, but generally in a rising trend. Technical non-related diversity constrains urban economic resilience, but technically related diversity show a U-shaped relation with urban economic resilience. Technical network density shows an upside-down U-shaped relation with regional resilience, a close technical network can promote technical communication innovation and boost regional economic resilience, but over close technical network plays in a negative role. This paper presents suggestions on promoting diversified technical production and optimized technical network structure to improve regional economic resilience.

Key words: technical diversity, technical network structure, regional economic resilience, Yangtze River delta area

摘要： 技术创新是增强区域经济韧性的关键因素。论文以长三角41个地级市为研究对象，基于发明专利数据测度技术相关多样性与非相关多样性并构建城市技术网络，运用反现实函数测度区域经济韧性，采用多元线性回归模型探讨技术多样性、技术网络结构对区域经济韧性的影响机理。研究结果表明：1）长三角地区的技术相关多样性水平、非相关多样性水平总体呈上升趋势，但时空分布不均衡，城市技术网络拓扑结构特征（密度、平均集聚系数、平均路径长度）差异大，在技术领域方面长三角的技术创新由传统冶金领域转向物理通讯领域；2）长三角地区经济韧性强度时空分布不均，整体呈现东低西高、南低北高的分布态势，经济韧性水平总体呈上升趋势；3）技术非相关多样性对城市经济韧性起抑制作用，技术相关多样性与城市经济韧性呈U型关系，技术网络密度与区域经济韧性呈倒U型关系，紧密的技术网络能够促进技术交流创新从而提升区域经济韧性，过度紧密的技术网络会加速风险的传播从而对区域经济韧性产生不利影响。最后，从促进相关多样性技术产生和优化技术网络结构等方面对提升区域经济韧性提出了对策建议。
