区域绿色创新效率评价及空间网络特征分析

Evaluation of Regional Green Innovation Efficiency and Analysis of Its Spatial Network Characteristics

构建区域绿色创新网络是推动绿色发展的重要载体,更是推动经济转型、完成“双碳目标”的核心引擎。使用SBM模型对甘肃省12个城市的工业绿色创新效率进行了测量和评价,并运用引力模型和社会网络分析方法对其空间关联特征进行了分析。研究表明:定西、庆阳等地绿色创新效率较高,张掖和平凉绿色创新水平较低;甘肃省绿色创新网络关联程度不高,等级性较强;兰州和嘉峪关对全省的绿色创新资源具有吸附效应,处于创新网络的中心位置;甘肃省工业绿色创新网络形成受到城市间的地理临近性、经济基础和创新支持系统差异的影响。建议应重点完善产业和环境政策,并在全局寻找方向,加强区域空间关联,进而全面提升甘肃省绿色创新水平。

The establishment of a regional green innovation network is a crucial carrier for promoting sustainable development and serves as an engine for economic transformation to achieve the"dual carbon goals."In this study,the SBM model is employed to measure and evaluate the industrial green innovation efficiency of 12 cities in Gansu Province.Additionally,the gravity model and social network analysis methods are applied to analyze the spatial correlation characteristics of the industrial green innovation.The research findings indicate that cities such as Dingxi and Qingyang exhibit higher levels of green innovation efficiency,while Zhangye and Pingliang demonstrate lower levels.The interconnection degree of the green innovation network in Gansu Province is not high,whereas it exhibits a strong hierarchical structure.Lanzhou and Jiayuguan play a central role in the innovation network,exerting an absorbing effect on green innovation resources across the entire province.The formation of Gansu Province's industrial green innovation network is influenced by the geographical proximity between cities,differences in economic foundations,and disparities in innovation support systems.Recommendations include a focus on refining industry and environmental policies,seeking a direction in the overall situation,strengthening regional spatial correlations,and thereby enhancing the overall level of green innovation in Gansu Province.
