Abstract

The prior literature has argued that inter-sectoral supply chain links provide an important channel for technology diffusion and productivity spillovers across industries, but whether such vertical spillovers influence industrial energy use has remained unexplored thus far. This study analyzes how the energy intensity of European industries is affected by vertical technology and energy productivity spillovers along the industrial supply chain. The analysis combines international input-output tables, energy use and patent data. Panel data from 2000 to 2014 for 27 industries in 29 countries is analyzed using panel fixed effects and instrumental variable estimation methods. The findings reveal that supply-use links channel significant vertical spillovers that promote a decline in energy intensity in downstream industries. These spillovers appear to be more strongly associated with overall energy intensity changes in upstream industries and, to some degree, with patented green innovations in upstream industries.

纵向溢出效应和欧洲工业的能源密集度

先前的文献认为，部门间的供应链联系为跨行业的技术扩散和生产率溢出提供了重要渠道，但这种垂直溢出是否会影响工业能源使用，迄今仍未得到探讨。本研究分析了欧洲工业的能源强度如何受到工业供应链纵向技术和能源生产率溢出效应的影响。分析结合了国际投入产出表、能源使用和专利数据。使用面板固定效应和工具变量估计方法，分析了 2000 年至 2014 年 29 个国家 27 个行业的面板数据。研究结果表明，供应-使用环节产生了显著的纵向溢出效应，促进了下游产业能源密集度的下降。这些溢出效应似乎与上游产业的整体能源强度变化以及在一定程度上与上游产业的专利绿色创新有着更密切的联系。

期刊介绍： Energy Economics is a field journal that focuses on energy economics and energy finance. It covers various themes including the exploitation, conversion, and use of energy, markets for energy commodities and derivatives, regulation and taxation, forecasting, environment and climate, international trade, development, and monetary policy. The journal welcomes contributions that utilize diverse methods such as experiments, surveys, econometrics, decomposition, simulation models, equilibrium models, optimization models, and analytical models. It publishes a combination of papers employing different methods to explore a wide range of topics. The journal's replication policy encourages the submission of replication studies, wherein researchers reproduce and extend the key results of original studies while explaining any differences. Energy Economics is indexed and abstracted in several databases including Environmental Abstracts, Fuel and Energy Abstracts, Social Sciences Citation Index, GEOBASE, Social & Behavioral Sciences, Journal of Economic Literature, INSPEC, and more.
