“…MEEC refers to the calculation of the sea area from which natural resources can be drawn without degrading its ecological function, it reflects the ability of the natural environment to supply resources and support social development (Hu et al, 2019). Owing to the depletion of non-renewable resources in the process of economic and social development, only renewable natural resources are considered when measuring the emergy ecological carrying capacity.…”

IntroductionMarine ecological security assessments are considered as a basis for coordinating marine economic development and ecological protection.MethodsWe propose an assessment method based on the emergy ecological footprint which first measures the emergy of the natural and economic elements of the marine ecosystem. Considering the role of economic, social and waste discharge factors in the marine ecosystem, an ecological security evaluation index is constructed, and a dynamic evaluation is conducted based on long time series data to characterize the change trend of ecological security.ResultsThe Guangxi marine ecosystem was selected as the case study, and the ecological security dynamic evaluation was conducted by collecting data from 2008 to 2020. The results show that Guangxi's marine ecosystem has always been in an ecologically secure state, but since 2010, the emergy ecological footprint intensity has been increasing, indicating ecosystem deterioration. Therefore, some targeted suggestions are put forward.DiscussionThis method provides a new assessment tool for marine ecological security evaluation and offers guidance for the sustainable development and utilization of marine ecosystems.

“…In this context, making use of the maritime economy is an essential and lucrative way to alleviate the paucity of land resources and the shrinking amount of space available for development. In addition to this, it has evolved into a favored region for the expansion of the global economy (Hu et al, 2019).…”

Purpose: Marine insurance is a form of civil contract in which the insurer makes the promise, in exchange for the insurance payment, to the insured person in whose favor the contract was established to compensate them for any losses they may have had as a result of the occurrence of hazards or accidents. The goal of the study is to determine the role of marine insurance on marine trade growth. Methodology: This was accomplished through the use of a desktop literature review. The use of Google Scholar was utilized in order to locate seminal references and journal articles that were pertinent to the investigation. Papers that were published no more than ten years prior were required to meet the inclusion requirements. Findings: The field of marine insurance is associated with insuring cargo that is being transported by sea, air, road, or rail; with insuring ships of varying types and sizes, ranging from pleasure craft to oceangoing commercial vessels; and with insuring liabilities that are associated with the transportation of cargo. There is an increased likelihood of risks occurring everywhere in the world. Unique contribution to theory, practice and policy: Since the performance outcome of marine insurance companies can have implications for the continued existence of shipping and other maritime businesses, the paper makes the recommendation that more specific policy interventions should be directed at the complete removal of impediments in the operating environment of marine insurance firms. In addition, policymakers should work on developing solutions that would, in some way, mitigate the adverse impact that insurance policies have on foreign trade.

“…Its connotation mainly includes the instability of the marine economic system itself, sensitivity to the changes of various factors, and the ability to withstand external influences. The stable development of marine economic system has become an important part of comprehensive national strategies of developed countries including the United States, Britain, Russia, France, Japan and others (Hu et al, 2019). These countries used…”

The sustainable development of the marine economic system to accurately grasp the dynamic evolution characteristics and main driving factors of the vulnerability of the marine economic system so as to effectively identify the problems in the operation of the marine economy is extremely important. Based on the establishment of a three-level assessment index system for the vulnerability of the marine economic system, the vulnerability of the marine economic system of Jiangsu Province in 2008-2016 was evaluated by using the comprehensive index model and the catastrophe progression model, and the results were compared based on the unified evaluation criteria. The main influencing factors were analyzed by principal component analysis and Pearson correlation analysis. It's found that 2014, 2015 and 2012 are in a general state, 2009 and 2010 are in a poor state, and the vulnerability state from 2008 to 2011 is lower than that in 2012. The overall volatility is small indicating a stable system. Among them, the scale of marine industry and profit and loss of marine resources are the main components of marine economic system vulnerability having the highest correlation with the vulnerability of marine economic system. This study enriches the theoretical method and empirical research on the vulnerability of the marine economic system and has practical significance in allowing for timely targeted control measures to affect the vulnerability of the marine economic system.
