Abstract: In view of the fact that the pollution index is not easy to measure,less attention has been paid to the undesirable outputs from the frontier quantitative research on marine fishery economy. In this study,it is assumed the negative effect caused by pollution of marine natural fisheries waters as the undesirable outputs. We adopt SBM (Slacks based measure)model to evaluate the economic efficiency of marine fishery in 11 coastal provincial-level areas of China from 2004 to 2015. Furthermore,we use Kernel density and Tobit model to analyze the spatio-temporal evolu-tion and influencing factors of economic efficiency of marine fishery. The results show that:In the time series perspective,the economic efficiency of marine fishery remains low,indicating that the marine fishery economic restructuring and upgrading has not yet achieved the desirable effect;From the perspective of time and space,the economic efficiency of marine fishery in the study area has shown a polarization trend and has not been effectively improved. This indicates that the level of marine fishery development is unbalanced in China. Generally speaking,the economic efficiency of marine fishery is low,which indicates that marine fishery economic development is relatively slow in China. In terms of industrial structure,the main reason for the low overall economic efficiency of marine fishery is attributed to the high proportion of the primary industry and the low level of technology,suggesting that marine fishery industry structure continues to follow the traditional mode that the primary industry dominates the economy. In order to reverse the negative relationship between the professional level and efficiency of fishermen's employment, it should be improved in quality and efficiency of the transfer industry and employment policy. In the future,marine fishery will face the dual challenges of institutional and structural transformation in China. According to the different resource endowments of coastal areas,firstly,the institutional innovation should hold a leading position in the transformation and upgrading of the system. Secondly,it is urgent to develop a differentiated and innovative development path. To improve the economic efficiency of marine fishery,we should adjust the industrial structure and optimize the regional layout.
