Abstract

In the context of the booming digital economy and the green transformation of society, information and communication technology (ICT) agglomeration is essential for promoting green technology innovation (GTI) and achieving sustainable development. Therefore, by utilizing a balanced dataset of 41 cities in the Yangtze River Delta for 2006–2019, the study examines the impact of ICT agglomeration on GTI with the system-generalized method of moments (SYS-GMM). Furthermore, we discuss the mediating and moderating roles of FDI and human capital, as well as the asymmetric relationship. Our results demonstrate that ICT agglomeration significantly promotes GTI and indirectly supports GTI by increasing FDI and improving human capital levels. FDI and human capital play a positive moderating role in ICT agglomeration for GTI. Moreover, ICT agglomeration has a significant positive impact on GTI only when the level of GTI is relatively high. Finally, based on the above findings, we provide several policy implications for promoting GTI in terms of ICT agglomeration.

信息通信技术集聚如何促进绿色技术创新？来自中国长三角的证据

在数字经济蓬勃发展和社会绿色转型的背景下，信息通信技术集聚是推动绿色技术创新、实现可持续发展的重要途径。基于此，本研究利用2006-2019年长三角41个城市的平衡数据集，采用系统广义矩量法（SYS-GMM）研究ICT集聚对GTI的影响。此外，本文还讨论了FDI与人力资本的中介和调节作用，以及两者之间的不对称关系。研究结果表明，信息通信技术集聚通过增加FDI和提高人力资本水平对GTI有显著促进作用，并间接支持GTI的发展。FDI和人力资本对GTI的ICT集聚具有正向调节作用。此外，只有当GTI水平较高时，ICT集聚才会对GTI产生显著的正向影响。最后，基于上述研究结果，本文提出了从信息通信技术集聚角度促进GTI发展的若干政策建议。

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.
