Pei, R., 2020. Effectiveness evaluation of marine fishery ecological sustainable policy based on comparative study. In: Wan, Z. (ed.), Coordinated Sustainable Development in Coastal Areas: Environment and Economy. Journal of Coastal Research, Special Issue No. 109, pp. 93–99. Coconut Creek (Florida), ISSN 0749-0208.With the current Chinese government's advocacy of sustainable marine fisheries, a series of studies have emerged on the efficiency of China's fishery policy. This paper studied latest measurement indexes and discuss them by comparative method. At present, the three latest pieces of research mainly discuss sustainable measures from three perspectives of economy, ecology, and economic ecological coordination and formed a preliminary evaluation system. These three studies are respectively Sun, Wang, and Su (2020), Han et al. (2020), Ji, Guo, and Zhang (2020). After a comparative study, the deficiencies of previous research are proposed and this work gives the suggestions based on the theoretical framework of social-ecosystem proposed by Ostrom (2009) and the three-dimension theory of "exposure -- sensitivity -- coping capacity" proposed by Polsky, Neff, and Yarnal (2007).

The coordinated development of a complex system refers to the harmonious and coherent evolution of its subsystems. From the perspective of the coordinated development of ecological–economic–social complex systems, this paper analyzes the coordinated development mechanism (CDM) of the mariculture ecological–economic–social (MEES) complex system, constructs a coordinated development evaluation indicator system for the MEES complex system, and adopts the comprehensive evaluation model and the coupling coordination degree (CCD) model to empirically analyze the coordinated development level of the MEES complex system in China from 2009 to 2020. The results show that the comprehensive development level of China’s MEES complex system has improved significantly during this period, with the comprehensive development index increasing from 0.25 in 2009 to 0.76 in 2020, transitioning from a poor to an excellent status. Simultaneously, the CCD of the system increased progressively, experiencing phases of near dissonance, barely coupling coordination, primary coordination, and intermediate coordination, before finally reaching a stage of good coordination. Based on these findings, we further discuss and propose countermeasures to promote the coordinated development of China’s MEES complex system.
