Construction and Comprehensive Evaluation of the High-quality Development Indicator System for Marine Economy in Guangdong Province

This article initially dissects the contemporary status of the development of Guangdong's marine economy, and based on the new development concept, develops a framework of evaluation indicators aimed at assessing the high-quality advancement of the marine economy. Then, it utilizes the entropy method to compute the high-quality development index and employs a linear regression model to analyze the key determinants influencing high-quality development. The research outcomes manifest that the trajectory of high-quality development of Guangdong's marine economy is steadily progressing, accompanied by marginal fluctuations in the interim period. The key factors affecting high-quality development include: R&D investment intensity, marine industrial structure upgrading index, marine industrial structure advancement level, industrial wastewater discharge, coastal port cargo throughput, actual utilization of foreign capital, urbanization level, and urban-rural consumption gap. Finally, targeted suggestions are proposed based on the above research results.
