Research on the classification of prosperity indexes of monitoring and early warning of marine development based on grey system theory

Abstract

This paper adopts the grey relational analysis model in grey system theory to design and construct the leading, synchronous and lagging indicators of monitoring marine development in Guangdong Province. At the same time, Granger causality test is used to verify and analyze the model. The results prove the rationality of the application of gray correlation method in the classification of prosperity indicators and its strong operability, which lays the foundation for the further research of marine monitoring and early warning system.
