摘　　要：采用上市公司500强企业网络数据、专利权转让数据和航班数据构建中国多层城市网络,实证检验了多层网络嵌入对中国城市能源利用效率的影响及特征。研究发现:①城市多层度数中心性和多层PageRank中心性对能源利用效率具有显著正向影响,结论在一系列稳健性检验后依然成立,表明城市多层网络中心性成为能源利用效率的重要来源。②多层网络嵌入的能源利用效率提升效应随城市绿色创新水平、创业孵化能力、产业结构高级化水平和数字经济发展水平趋于增强,表明城市吸收能力正向调节着多层网络嵌入与能源利用效率的关系。③非资源型城市和资源型城市的能源利用效率分别受益于多层PageRank中心性和多层度数中心性的提升,中西部城市能源利用效率从多层网络嵌入中获得的收益明显高于东部城市。城市多层网络嵌入的研究必然对城市能源利用效率产生重要影响。The urban system in China is essentially a multilayer network composed of evolving and interacting single-layer relational networks.Understanding how the embedded characteristics of cities in these multilayer networks influence energy utilization efficiency is crucial for effectively balancing economic growth and sustainable development in China.This article sets out to empirically investigate the impacts of multilayer network embeddedness on energy utilization efficiency based on a panel data set covering 282 prefecture-level and above cities in China in 2005,2010,2015,and 2020.To this end,three single networks,i.e.,network of top 500 public companies,network of patent transfer,and network of flight,are used to construct the edge-colored multigraph.Three main findings stand out.First,both multilayer degree centrality and multilayer PageRank centrality have a significant positive impact on the energy utilization efficiency of Chinese cities,which is still valid after a series of robustness and endogeneity tests.Second,urban absorptive capacity acts as a positive moderator between multilayer network embedding and energy utilization efficiency,with energy efficiency effects increasing alongside improvements in urban green innovation,entrepreneurial incubation,industrial structure upgrading,and digital economy development.Third,the energy efficiency effects of multilayer network embedding demonstrate multidimensional heterogeneity,with non-resourcebased cities benefiting more from multilayer PageRank centrality and resource-based cities from multilayer degree centrality.In addition,central and western cities experience greater energy efficiency gains from multilayer network embedding compared to eastern cities.The results underscore the significance of a city’s integration into extensive networks for its energy performance,highlighting network capital as a crucial component of urban energy utilization efficiency.The paper also fills the gap in the juxtaposition between agglomeration and network economies,by clarif
