摘　　要：国家战略区域高质量发展是当今学界所关注的热点话题。测度2016—2022年淮海经济区经济高质量发展水平,通过修正引力模型,利用社会网络分析法和QAP方法分析淮海经济区经济高质量发展的空间网络结构及影响因素。研究发现:淮海经济区经济高质量发展水平逐年提升,但高水平城市数量偏少,经济高质量发展水平存在较强的空间异质性;经济高质量发展整体网络结构呈现出空间网络密度逐渐增大但整体水平较低,网络集聚弱联结状态显著的特征;个体网络结构显示,徐州市、临沂市、宿迁市为区域中心城市,发挥着“中心行动者”的作用,是淮海经济区信息传播媒介。城市间经济高质量发展空间网络呈现出明显“马太效应”,区域一体化程度有待提高;淮海经济区经济高质量发展空间网络由四大子群构成,存在小群体集聚发展特征;政府支持强度、对外开放、科技创新、产业结构、城市化强度的差异都会直接造成城市间经济高质量发展水平的差异。The high-quality development of national strategic regions has become a focal point of contemporary academic discourse.This study measures the level of economic high-quality development in the Huaihai Economic Zone from 2016 to 2022 by employing a modified gravity model,alongside social network analysis and QAP methods to examine the spatial network structure and influencing factors of economic high-quality development within this region.The findings reveal that while the level of economic high-quality development in the Huaihai Economic Zone has been steadily improving over the years,there remains a limited number of cities achieving high-level status,indicating significant spatial heterogeneity in economic quality.The overall network structure for economic high-quality development exhibits an increasing density;however,it is characterized by relatively low levels and notable weak connectivity within its clustering.Individual network structures identify Xuzhou,Linyi,and Suqian as regional central cities that act as“central actors”,serving as key conduits for information dissemination throughout the Huaihai Economic Zone.The inter-city spatial network for economic high-quality development demonstrates a pronounced“Matthew effect”,suggesting that regional integration requires enhancement.Furthermore,the spatial network for economic high-quality development in the Huaihai Economic Zone comprises four major subgroups exhibiting characteristics typical of small group clustering.Variations in government support intensity,openness to external markets,technological innovation capabilities,industrial structure diversity,and urbanization intensity directly contribute to disparities in levels of economic high-quality development among cities.
