摘要
国内城市的创新效率及其空间关联性对于推动经济高质量发展起着重要作用,“一带一路”倡议促进了城市间在创新领域的交流互动和资源整合,也对创新效率的空间关联产生了深远影响。文章以“一带一路”倡议为背景,运用社会网络分析法对中国284个地级市的创新效率进行研究,探讨“一带一路”倡议对中国城市创新效率及其空间关联的影响。文章运用了DEA-Malmquist法测度各城市的创新效率,利用引力模型构建了中国城市创新效率网络,通过网络指标分析探索“一带一路”倡议对创新效率空间关联的影响,并采用QAP回归定量分析了创新效率网络的影响因素。研究发现:(1)近年来中国城市创新效率持续提高,但节点城市与非节点城市在创新效率上的差异在“一带一路”倡议实施后有所扩大;(2)“一带一路”倡议实施后,城市间创新效率的关联得到明显加强;(3)空间距离、经济发展、人力资本、对外开放和政府支持等因素均对创新效率存在显著影响;(4)“一带一路”倡议下城市创新效率网络的空间关联主要体现在节点城市对周边城市的溢出效应上。本研究在理论上拓展和丰富了对创新效率空间关联的研究,在实践上为创新效率的提升提供了政策建议。
The innovation efficiency and spatial associations of domestic cities play a crucial role in promoting high-quality economic development.The"Belt and Road Initiative"(BRI)has facilitated exchanges and resource integration in the field of innovation among cities,profoundly impacting the spatial associations of innovation efficiency.This paper,set against the backdrop of the BRI,employed a social network analysis to study the innovation efficiency of 284 prefecture-level cities in China,and explored the impact of the BRI on the innovation efficiency and spatial associations of Chinese cities.The paper used the DEA-Malmquist method to measure the innovation efficiency of each city and constructed a network of innovation efficiency among Chinese cities using the gravity model.Through the network indicator analysis,it explored the impact of the BRI on the spatial associations of innovation efficiency and employed the QAP regression to quantitatively analyze the influencing factors of the innovation efficiency network.The study found that:(1)In recent years,the innovation efficiency of Chinese cities has continuously improved,but the gap in innovation efficiency between node cities and non-node cities has widened after the implementation of the BRI;(2)After the implementation of the BRI,the associations of innovation efficiency among cities have significantly strengthened;(3)Factors such as spatial distance,economic development,human capital,openness to the outside world,and government support all have significant impacts on innovation efficiency;and(4)Under the BRI,the spatial associations of the urban innovation efficiency network are mainly reflected in the spillover effects of node cities on surrounding cities.This study will theoretically expand and enrich the research on the spatial associations of innovation efficiency and provide policy recommendations for improving innovation efficiency in practice.
