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.
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.
