Spatial and Temporal Differentiation of the Coordination and Interaction among the Three Fishery Industries in China from the Value Chain Perspective

Abstract

The efficiency change, mutual cooperation, and interaction among the three fishery industries in China can accurately reflect the level of economic development within the industry. Studying the relationships between the three fishery industries under the existing structural system is conducive to enhancing the endogenous power and steady progress of the industry. Using the DEA-Malmquist model, gray correlation, impulse response, and variance decomposition methods, this paper focuses on the specific value appreciation process of the three fishery industries, namely, fishery capture and aquaculture (primary industry), aquatic processing (secondary industry), and recreational fishery activities (tertiary industry), in order to analyze the synergy and interactive response relationship among the three fishery industries during the period of 2003 to 2020 based on the value chain. We propose specific policy suggestions regarding the overall efficiency level and integration degree of the three fishery industries. The results show the following: (1) the efficiency of fishery capture and aquaculture (primary industry) and aquatic processing (secondary industry) show significant regional differences, and the change in trend in the efficiency of recreational fishery activities (tertiary industry) is better than that of the other two. (2) Most of the synergy degrees of fish capture and aquaculture efficiency, aquatic processing efficiency, and recreational fishing efficiency, are medium and above. (3) The interactions among the efficiencies of the three fishery industries in the country and that in different regions vary. From a national perspective, the efficiency of the fishery industries can be dependent on economic inertia. There is a regional heterogeneity among the interactive responses to the efficiency of the three fishery industries in China; the interaction of fishery value chain efficiency in the four economic regions differs in both strength and direction. Exploring the synergy and interactive response among the three fishery industries in China from the value chain perspective can provide a basis for the precise governance of different regional characteristics and help to modernize the fishery industry.
