Abstract
The marine fishery resources are declining with the increase of fishing intensity, and the sustainable development of marine fishery economy has become the focus of attention. In this paper, the economic loss of marine natural fishery resources is taken as the undesired output. The SBM model is used to evaluate the economic efficiency of marine fisheries in 11 provinces and cities in China’s coastal areas from 2004 to 2015. Based on this, decoupling theory is adopted to analyze the spatial and temporal evolution pattern of marine fishery economic efficiency and resource consumption in various provinces and cities. The results show that: 1) Based on the perspective of time and space, the economic efficiency of marine fisheries in 11 provinces and cities along the coast of China is polarized and has not been effectively improved, indicating that the level of fishery economic development in China’s coastal areas is unbalanced; 2) Based on the overall perspective, the overall economic efficiency of China’s marine fisheries is low, indicating that China’s marine fishery economy is developing at a slower rate; 3) Based on the perspective of decoupling theory, the economic efficiency of marine fisheries in China and the consumption of fishery resources have shown a trend in the research period. The structure of China’s marine fishery industry, which is dominated by traditional fisheries, needs to be adjusted.

The results show that: 1) Based on the perspective of time and space, the economic efficiency of marine fisheries in 11 provinces and cities along the coast of China is polarized and has not been effectively improved, indicating that the level of fishery economic development in China’s coastal areas is unbalanced; 2) Based on the overall perspective, the overall economic efficiency of China’s marine fisheries is low, indicating that China’s marine fishery economy is developing at a slower rate; 3) Based on the perspective of decoupling theory, the economic efficiency of marine fisheries in China and the consumption of fishery resources have shown a trend in the research period
Based on the “China Fishery Eco-Environmental Bulletin” (Ministry of Agriculture, 2004-2015), the estimation principle of the economic loss of marine natural fishery resources, according to the estimation method of the economic loss of natural fishery in the bulletin, the specific calculation of the 11 provinces and municipalities in China’s coastal areas from 2004 to 2015 Unexpected output value of natural fishery economy as a quantitative indicator of undesired output
Summary
Gao & Chen (2003) based on the scarcity theory of resources, confirmed the continuous reduction of offshore fishing grounds and Marine fishery resources and the decline of the economic efficiency of fishery production factors, which has become the main factor restricting the sustainable development of China’s marine fisheries. Based on the traditional DEA model, the efficiency relationship between production factors and expected output (generally the total output of fishery economy) is mainly studied from the perspective of performance evaluation of input and output of Marine fishery economy or the development level of fishery economy. This paper constructs an SBM-DEA model that considers undesired outputs, and measures the economic efficiency of marine fisheries in 11 provinces and municipalities in China’s coastal areas from 2004 to 2015, and describes the evolution of its spatial and temporal patterns. On the basis of analyzing the distribution characteristics of time and space patterns in various regions, using the decoupling theory, the economic efficiency and resource consumption of marine fisheries during the “Eleventh Five-Year Plan” (2007-2010) and “Twelfth Five-Year Plan” (2011-2014) The relationship is measured and analyzed for its evolution, in order to provide reference for the economic development of marine fisheries
