Comprehensive Evaluation Index System for Integration of Freshwater Fishery Industry Chain Based on Structural Equation Modeling

According to the principles for index design, based on the existing index systems of other related industries, this paper proposed the conceptual model of internal potential influence factors for integration of freshwater fishery industry chain. On such basis, this paper screened out the observed variables that explain each influence factor, i.e. bottom indexes, established the comprehensive evaluation index system for integration of freshwater fishery industry chain, and then constructed the structural equation model for integration of freshwater fishery industry chain, and fitted and optimized the model by confirmatory factor analysis. Principal component analysis was applied to comprehensively evaluate the integration performance of freshwater fishery industry chain.
