Research on China’s green total factor productivity of aquaculture industry and its influencing factors

The burgeoning field of ocean data and its application to resource management demands rigorous assessment of sustainability practices, and a recent study focusing on China’s aquaculture industry provides a valuable data point. This research, utilizing sophisticated modeling techniques, quantifies the Green Total Factor Productivity (GTFP) of China's aquaculture—a critical sector given its global significance in food security—and identifies key factors influencing its green development. The findings highlight a complex interplay of regional disparities, technological adoption, and infrastructural challenges. Understanding these dynamics is particularly relevant given escalating geopolitical tensions in the surrounding waters, as evidenced by recent incidents like the US Condemns China’s ‘Dangerous And Aggressive’ Actions After Philippine Sailor Injured In South China Sea Clash and the increasing scrutiny of China's activities in sensitive maritime zones. Further complicating the landscape is the strategic importance of marine resources, explored in a related study on Capability heterogeneity and dual technological paths: a micro-level empirical analysis of TFP improvement in Chinese marine enterprises, illustrating the country’s drive towards technologically advanced marine operations.

The study’s methodological rigor, employing the Super-SBM model and GML index, allows for a nuanced assessment of GTFP across freshwater and marine aquaculture systems. The observed regional discrepancies, with freshwater aquaculture demonstrating a clear east-to-west gradient and mariculture performing variably across coastal provinces, underscore the need for tailored policy interventions. The dependence on technological progress for aquaculture growth, particularly evident in the slower development of mariculture due to limited technology diffusion, is a key takeaway. The findings that industrial scale, structure, and urbanization positively impact GTFP, while transportation accessibility negatively affects it, offer practical guidance for optimizing resource allocation and infrastructure development. It is also noteworthy that the research identifies the detrimental impact of fishery disasters on mariculture efficiency, a vulnerability that demands proactive risk mitigation strategies. This aligns with emerging trends such as the US Coast Guard Tracks First Chinese Arctic-Bound Research Ships Through US EEZ In 2026, highlighting the increasing operational complexity and potential environmental risks associated with expanding maritime activities.

Beyond the specific findings regarding aquaculture, this research contributes to a broader understanding of sustainable industrial development in a rapidly changing global context. The emphasis on empirical data and validated methodologies reinforces the importance of rigorous scientific assessment in informing policy decisions related to resource utilization and environmental protection. The study’s identification of factors inhibiting GTFP, such as transportation bottlenecks and the adverse effects of fishery disasters, provides valuable insights for policymakers aiming to foster more resilient and sustainable aquaculture practices. The methodology employed – specifically the Super-SBM model – offers a framework applicable to assessing GTFP in other resource-intensive industries, contributing to the development of a more comprehensive understanding of sustainable development performance across diverse sectors. The consistent use of terms like "validated," "measurable," and "empirical" reflects a commitment to scientific integrity, aligning with World Data Ocean's core values.

Ultimately, this research highlights the critical need for integrated data ecosystems and real-time monitoring of key climate indicators to effectively manage ocean resources and mitigate environmental risks. The findings underscore that technological innovation, while essential, must be coupled with optimized infrastructure, targeted policy interventions, and robust environmental governance mechanisms. A key question moving forward is whether the demonstrated regional disparities in GTFP can be effectively addressed through collaborative efforts and knowledge sharing, or if they will exacerbate existing inequalities and hinder the overall progress toward sustainable aquaculture practices. Longitudinal data collection and analysis, continuously calibrated against emerging climate indicators, will be crucial for tracking progress and adapting strategies to ensure the long-term health and productivity of China's aquaculture industry—and, by extension, global food security.
