Abstract: With global population growth and economic development, the demand for marine resources is constantly increasing, and fishing activities are facing greater pressure. Overfishing and unreasonable fisheries management have led to some fishery resources facing depletion and ecosystem degradation. The health of marine ecosystems is crucial for the ecological balance of the Earth. Overfishing and ecosystem destruction may lead to ecosystem collapse, causing long-term impacts on many species and ecological functions that rely on marine organisms. With the development of technology and innovation, new fishery technologies and management methods continue to emerge, which have the potential to improve the ecological efficiency of fisheries and optimize resource utilization. Based on the panel data of some coastal selected provinces from 2005 to 2019, the NDDF model is used to calculate the marine fishery efficiency and target the path of marine fishery eco-efficiency improvement. The results of the study show that, in terms of spatial pattern, the eco-efficiency value of marine fisheries in southern coastal provinces and municipalities in China is higher than that in northern coastal provinces and municipalities as a whole. Shandong province has the highest eco-efficiency value in the Bohai Rim region, and Shanghai city has the highest eco-efficiency value in the Yangtze River Delta region. In terms of time series, the eco-efficiency values of marine fisheries in the eastern coastal provinces and municipalities of China showed a fluctuating increase, and two peaks occurred in 2011 and 2019. Provinces and cities with high eco-efficiency values have the common characteristics of enjoying national policy support and reasonable resource allocation, while provinces and cities with lower eco-efficiency values have the common characteristics of irrational industrial structure, weak environmental protection awareness, and less scientific and technological investment. Based on this, suggestions are put forward on improving the eco-efficiency value of marine fisheries: vigorously developing fishery-related science and technology, optimising the industrial structure of coastal cities, and increasing policy support.Abstract: With global population growth and economic development, the demand for marine resources is constantly increasing, and fishing activities are facing greater pressure.

Abstract: From the perspectives of conjugate resources and their transformations, this paper proposes conjugate contradiction analysis method, and discusses the urban governance model and governance pathway of the popularity of "Zibo barbecue". The research suggests that there are two main contradictions in Zibo's urban governance. One is the contradiction between emotional governance and rigid governance, among which emotional governance involves mainly the allocation, optimization, and utilization of soft resources and non-material resources in the city. And the other is the contradiction between a proactive government and an effective market, involving mainly the allocation, optimization, and utilization of material and hard resources in the city. The study reveals that the "synergistic governance between an effective market and a proactive government with emotional governance as a core feature" is the main approach for Zibo to solve the above contradictions. Four governance pathways including "tempering hardness with emotion and coupling hardness with softness", "promising government and effective market", "online marketing, offline realization" and "endogenous drive, exogenous promotion" are refined. The research shows that the allocation, optimization, and utilization of governance resources in the urban governance process can be understood more comprehensively, and the essence and laws of urban governance can be revealed more profoundly with conjugate contradiction analysis method, which includes structure in terms of (soft part and hard part) systematicity, composition in terms of (real part and virtual part) solidity and function, value in terms of (negative part and positive part) oppositeness, and dynamics in terms of (latent part and apparent part) changeability. The research results provide useful references and insights for urban governance and high-quality development practices.Abstract: From the perspectives of conjugate resources and their transformations, this paper proposes conjugate contradiction analysis method, and discusses the urban governance model and governance pathway of the popularity of "Zibo barbecue".
