牡蛎养殖业绿色发展水平评价模型构建与实证分析OA

With the growing prevalence of green development concepts and the continuous advancement of green development strategies,the oyster aquaculture industry faces increasingly stringent environmental regulations.To promote the industry's green transformation,there is an urgent need for a systematic and scientific assessment of its green development level.This study employs R-clustering factor analysis to construct an indicator system for evaluating the green development level of the oyster aquaculture industry.Indicator weights are determined using the arithmetic mean derived from the Random Forest algorithm and the CRITIC method.A fuzzy joint evaluation method combining the effectiveness coefficient method,TOPSIS method,and rank-sum ratio method is then applied to comprehensively measure the green development level of China's oyster aquaculture industry.The results indicate that the green development levels of the six major oyster-producing provinces,ranked from highest to lowest,are as follows:Fujian,Guangxi,Shandong,Liaoning,Guangdong,and Zhejiang.Fujian demonstrated the strongest performance,while Guangxi and Shandong showed comparable levels.Liaoning,Guangdong,and Zhejiang scored below 80,indicating a medium-to-low development level.Based on each province's industrial status and primary challenges,this study further proposes targeted policy recommendations.
