Abstract: Mariculture plays a crucial role in the marine industry, holding significant importance for global food provision, coastal economic growth, and marine ecological preservation. However, mariculture encounters challenges such as resource scarcity, environmental contamination, and market instabilities. The broad adoption of digital technology presents valuable growth prospects for mariculture. Employing the SBM-GML model, this study assesses the green total factor productivity of mariculture across ten coastal provinces in China from 2006 to 2022 and investigates the influence of digital economy policies on the sector’s green total factor productivity. The results reveal an overall fluctuating upward trend in the green total factor productivity of Chinese mariculture, ranging between 0.975 and 1.074, with variations in technical efficiency surpassing those in technological progress. This underscores that enhancing the green total factor productivity in China’s mariculture sector primarily hinges on technical efficiency. Noteworthy regional disparities point to an imbalance in regional mariculture advancement. Additionally, this study illustrates the favorable impact of digital economic strategies on the sector’s green total factor productivity, with varying effects observed across diverse regions. These findings provide empirical support and policy recommendations which will help government authorities formulate and implement effective policies, fostering the green transformation of mariculture amid the evolving digital economy landscape.
