... In conclusion, this paper's contributions are as follows: firstly, in contrast to the existing literature, which has conducted research through the perspectives of energy saving and environmental protection expenditure (Tang et al. 2022a, b;Fan et al. 2022), environmental regulation , and industrial agglomeration (Tang et al. 2022a, b), this paper incorporates the behavior of regional green technology innovation activities into the analytical framework to investigate whether local governments have self-interest tendencies; secondly, unlike most of the literature, which only constructs green economy indicators based on industrial "three waste" emissions (Chaaben et al. 2022), this paper introduces carbon dioxide emission indicators into the measurement of green economy indicators and employs them to examine the relationship between local government fiscal decentralization and green economy development. On this basis, the heterogeneous differences among the eastern, central, and western regions of China, as well as the policy-supported Yangtze River Economic Belt, are investigated through theoretical analysis and empirical tests, and the impact of such geographical heterogeneity on regional economic growth is discussed further. ...

... Also, most of the studies have used CO2 emissions as the environmental quality indicator, whereas the CEI has been a fundamental concept recently [34]. From the KSA perspective, there are naturally some studies [e.g., 24,27,29,30,31,32,33,34] in the literature. However, most of them have examined the KSA by using traditional econometric 7 approaches (e.g., ARDL, dynamic ARDL simulations, DOLS, FMOLS, quantile regression, VECM), whereas some others have made an empirical examination by using relatively olddated data. ...
