摘要:

厘清低碳技术创新合作网络对绿色发展效率的影响及其空间溢出机制,有助于促进创新资源跨区域配置与城市绿色协同转型。本文基于2011—2021年长三角41个城市的低碳技术联合申请专利及社会经济数据,运用社会网络分析、超效率SBM模型、空间分析和空间杜宾模型,考察低碳技术创新合作网络与绿色发展效率的时空演化特征,并识别不同网络位置的直接效应和间接效应。研究发现:①长三角低碳技术创新合作网络的专利合作数量、网络密度和复杂程度总体上升,至2021年形成以上海、南京、杭州和宁波等城市为核心的菱形结构,并呈现“核心-次核心-边缘”的等级层次特征。②长三角绿色发展效率总体提升,空间格局由“两极引领”演变为“两区集聚”,网络密度与绿色发展效率的总体变化呈显著正相关。③不同网络位置对绿色发展效率的作用存在差异,度中心度主要表现为显著正向间接效应,接近中心度主要表现为显著正向直接效应,中介中心度的影响不显著。研究结论可为优化长三角低碳技术创新合作网络、发挥中心城市的技术溢出效应及推进区域绿色协同转型提供参考。

Abstract:

Clarifying how low-carbon technology innovation collaboration networks affect green development efficiency and generate spatial spillovers can facilitate the cross-regional allocation of innovation resources and coordinated urban green transitions. Using data on jointly filed low-carbon technology patents and socioeconomic indicators for 41 cities in the Yangtze River Delta from 2011 to 2021, this study applies social network analysis, the super-efficiency slacks-based measure model, spatial analysis, and the spatial Durbin model to examine the spatiotemporal evolution of the collaboration network and green development efficiency and to identify the direct and indirect effects associated with different network positions. The results show that: ① The number of patent collaborations, network density, and network complexity increased overall. By 2021, the network had developed into a diamond-shaped configuration centered on Shanghai, Nanjing, Hangzhou, Ningbo, and other cities, with a hierarchical core-subcore-periphery structure. ② Green development efficiency improved overall, and its spatial pattern shifted from dual-pole leadership to dual-zone agglomeration. Changes in network density and overall green development efficiency were significantly positively correlated. ③ Different network positions had distinct effects on green development efficiency. Degree centrality was mainly associated with a significant positive indirect effect, closeness centrality with a significant positive direct effect, while the effect of betweenness centrality was not statistically significant. These findings provide implications for optimizing the low-carbon technology innovation collaboration network, strengthening technological spillovers from central cities, and advancing a coordinated green transition across the Yangtze River Delta.
