Research on the Influence Mechanism of Green GDP, Green Network Security, and Digital Economy Based on Gray Correlation Model

This paper explores the impact that using GGDP (Green GDP) as an important indicator of a country's economic health will have on global climate mitigation. The GGDP values of 24 EU countries are calculated based on Eurostat data, and greenhouse gas emissions, precipitation, etc. are selected as variables, global data are collected for five years from 2015 to 2019, and the expected impact is estimated using gray correlation model and ridge regression model, which concludes that GGDP is negatively correlated with the climate indicators, and has a significant impact on climate mitigation. The resultant research is applied to the impact of green network security on network ecology and digital economy, selecting network ecological cleanliness, network energy utilization efficiency, and network security inputs as variables to be applied to the model, and the study concludes that green network security has a positive positive impact on the digital economy, and can promote the sustainable development of the digital economy.
