黄河下游城市协同创新网络演化特征及影响因素分析
Evolution characteristics of collaborative innovation network in cities in the lower reaches of the Yellow River and its analysis of influencing factors
摘要
Abstract
Innovation is the primary driving force for economic development;promoting urban col-laborative innovation is an important step for improving the quality of regional economic develop-ment.Ecological protection and high-quality development in the Yellow River Basin have become national strategies.As for its important area,it is urgent to explore the spatiotemporal evolution characteristics and influencing factors of urban collaborative innovation network in the lower rea-ches of the Yellow River.Based on the joint patent application data published by the National In-tellectual Property Rights,a collaborative innovation network among 34 cities in the lower rea-ches of the Yellow River from 2011 to 2020 is constructed.The dissertation uses the social net-work analysis method to analyze its evolutionary characteristics and uses the QAP regression a-nalysis to reveal the impact mechanism for proximity factors on urban innovation cooperation.The results are as follows:①The innovation network gradually develops into a complex and dense structure and gradually evolves into a core edge structure with Jinan,Zhengzhou and Qing-dao as core nodes.②Proximity factors other than cultural proximity significantly promote inno-vative cooperation between cities,and institutional proximity has the greatest impact.③ Institu-tional proximity exhibits a complementary relationship with both geographical and technological proximity,while simultaneously serving as a substitute for cultural proximity.关键词
