    Abstract

    With the rapid development of the marine economy, the demand for marine resources development and the pressure on marine environmental protection are gradually increasing. It is critical to evaluate and analyze the driving forces of marine sustainable development in order to promote the coordinated development of the marine economy, resources and environment. Taking Jiangsu Province of China as an example, this paper constructs an evaluation index system for marine sustainable development from the three aspects of marine economy, resources and environment, and calculates the weight of the variation coefficient for each indicator. Based on the grey relational model, the average value of the relational degree, calculated by the average value method of correlation coefficients and the weighting method, is then used to evaluate the status of marine sustainable development in this province. The comprehensive index model is used to analyze the dynamic trend of the evolution of marine sustainable development. The driving forces of marine sustainable development are analyzed by the path analysis method combined with the average values of the grey relational degree for each indicator. This analysis found that the marine sustainable development in 2016 and 2012 was good, the situation in 2007 was bad, and the remaining years were intermediate. Compared with the previous years, the optimal conditions of 2008 and 2012 were obvious. The main driving factors of marine sustainable development are cargo throughput of coastal ports, economic losses caused by storm surges in coastal areas, the area of marine nature reserves in coastal areas, coastal wind power generation capacity, and marine biodiversity.

    1 Introduction

    With the increasing demand for resources for consumption, coastal countries all over the world consider marine sustainable development as an important development strategy. Marine sustainable development is reflected by several factors, such as the total amount of marine economy that has increased to a certain stage, marine industrial structure is optimized, marine resource development is efficient and reasonable, the marine ecological environment is harmonious, and marine comprehensive strength is improved, which together realize the dynamic balance of the “marine economy-resources-environment” system (Eikeset et al., 2018). Marine resources and the environment are the basis and guarantee for the development of the marine economy, but with increasing marine development, the pressures on marine resources and the environment are increasing day by day (Selina, 2018). The contradictions between marine resources, environment and economy are becoming increasingly prominent. As a result, the system is faced with a series of problems and risks, such as low utilization efficiency of marine resources, decline of biodiversity, frequent occurrence of marine disasters, tension between man and land, aggravation of environmental pollution, degradation of the ecological environment, an extensive mode of economic growth, and increasing transformation pressures (Zhang et al., 2019a). Therefore, with the rapid development of the marine economy, marine sustainable development has gradually become the focus of attention and the key for enhancing the comprehensive national strength of coastal countries.
