Assessing the Effectiveness of Aquaculture Technology Dissemination in Eastern China: A Biotechnological Approach

Abstract

Utilizing the three-stage Data Envelopment Analysis (DEA) model, this study evaluates the efficiency of aquaculture technology dissemination across eastern China's coastal regions from 2011 to 2020. Our analysis incorporates a comprehensive assessment of the influences shaping this efficiency, including the number of aquaculture technology promotion platforms, the educational qualifications of personnel involved, local farmers' per capita income, and the impact of regional disasters. By adjusting for environmental and stochastic variations, we pinpoint the true efficiency levels. The findings indicate that regions such as Liaoning, Shandong, Jiangsu, Fujian, and Guangdong demonstrate optimal comprehensive technical efficiency in aquaculture technology promotion. Conversely, Hebei, Shanghai, and Hainan have not achieved peak efficiency, primarily due to suboptimal scale efficiency. In Tianjin, Zhejiang, and Guangxi, both pure technical efficiency and scale efficiency fall short of the efficiency frontier. The study underscores the need for each region to tailor its resource allocation to enhance the effectiveness of its aquaculture technology promotion strategies, aiming to establish a more robust and efficient system.
