Study on temporal and spatial evolution and influencing factors of fishery economic development quality in China
Taking 29 provinces(regions and cities)in China from 2011 to 2021 as the research object,this paper uses Entropy method and Theil index to measure the quality level of fishery economic development and the difference index of regional fishery economic development quality.The main factors affecting the development quality of fishery economy in China are analyzed by using the geographical detector model.The results show that:(1)The development quality of China's fishery economy is on the rise,and the development level of the eastern region is higher than that of the western region.(2)The quality of regional fishery economic development in China shows a spatial distribution pattern of"high gap in the east and west,low gap in the middle and northeast",and the overall difference come from within the region.(3)The main factors affecting the quality of fishery economic development are the intensity of fishery opening and the level of fishery ecology,and the influence of fishery resource level and fishery sharing level is relatively weak.The interaction of different influence factors shows a double factor enhancement type.
