A research on influencing factors on the international cooperative exploitation for deep-sea bioresources based on the ternary fuzzy DEMATEL method

In the 21 century, in order to effectively solve the problem of declining offshore living resources, maritime countries have started to exploit deep-sea marine bioresources to provide a substantial resource foundation for fisheries development, marine medicine research and genetic research. Recently, due to the unbalanced distribution of resources and technologies in the world, the deep-sea bioresources cooperative development projects have successively been initiated among countries. In the present study, in order to speed up the deep sea research processes in China and promote the international cooperation, the factors that affect the international cooperative development for deep-sea bioresources were identified firstly. Nine factors were identified as funding level, technical level, policy, politics and diplomacy, economy, resources, ecology, geography and culture. The ternary fuzzy DEMATEL method was used to analyze the impact level of these factors. According to prominence, the direct influences of the factors were analyzed. The top three influencing factors are economic environment, politics and diplomacy environment, and technical level, while ecological environment has the least impact. According to relation, the indirect influences of the factors were also identified, revealing that policy, political and diplomacy, economy, geography, culture environment and resources level have indirect influence. It was suggested that these six factors firstly influence the other three factors, and then the six factors indirectly influence the international cooperative development for deep-sea bioresources. Based on the above analysis, from the aspects of economy, political diplomacy, policy, funding, culture, ecology and the relationship among the influencing factors, suggestions were put forward to promote the rapid and sustainable development of the international cooperative development for deep sea marine bioresources.
