Gao, S.; Zhao, L.; Sun, H.H., and Liu, W., 2020. Comprehensive evaluation and main influencing factors of sustainable development of marine economy based on GRA and LWCI models.

With the rapid development of marine economy, resource demand and ecological environment pressure are increasing. It is of great significance to evaluate the sustainable development of marine economy to promote the coordinated development of marine economy, resources and ecological environment. This paper constructs the evaluation index system from four aspects: the scale of marine industry, the profit and loss of resources, ecology, environment. The sustainable development of marine economy in Jiangsu Province is evaluated by Grey Relational Analysis model (GRA) and Linear Weighted Composite Index model (LWCI). The main influencing factors are objectively analyzed by calculating the grey relational grade of each evaluation index. This Research found that the sustainable development level of marine economy in 2010 was in a general state, and the other years were in a good state. The wetland area in coastal areas, Area of Marine Nature Reserve, Standard rate of industrial wastewater discharge in coastal areas, Biodiversity indicators are the most important influencing factors affecting the sustainable development level of marine economy.
