Evaluation of the innovation ability of China's marine fisheries from the perspective of static and dynamic

Marine fisheries innovation ability (MFIA) has been considered as a key factor to promote the modernization and sustainable development of fisheries. In this study, an evaluation index system was constructed from three dimensions: innovation input, innovation output and innovation environment. Using a static evaluation model involving a combined evaluation method based on the Gini criterion and a dynamic evaluation model with speed characteristics, the comprehensive evaluation of the MFIA was firstly conducted from both the static and dynamic perspectives based on 2009–2018 data from 11 coastal provinces and cities of China. The static evaluation results showed that the overall level of the MFIA in China was low with slight growing trend. The 11 provinces and cities could be divided into three levels according to the MFIA, and the stronger the MFIA, the greater the ascent degree. The dynamic evaluation results displayed changing state of the MFIA was closely related to policy orientation in China, and both the time entering the upgrading stage of the MFIA and growing stability of the MFIA were different among the 11 provinces and cities. The dynamic evaluation results were basically consistent with the static evaluation results, which indicated the reliability of the conclusion. The evaluation of the MFIA could provide an insight for regional innovation development level of marine fisheries, and provide a basis for regional governments to formulate more reasonable policies of marine fisheries development.
