“…According to the agricultural production theory, land, labor, machinery, and seed are vital inputs for agricultural production (Asche et al, 2009;Aung et al, 2021). Scuderi and Chen (2018) Drawing on the characteristics of freshwater aquaculture and the existing literature (Zou & Huang, 2015;Zhong et al, 2023), this article chooses four variables to construct the input variable system: aquaculture acreage, number of farming vessels, number of aquaculturists and nominal value of intermediate input.…”

“…The existing literature on evaluating ecological efficiency mainly focuses on transportation (Kuosmanen & Kortelainen, 2005), energy (Camarero et al, 2012; Todorovic et al, 2016), and cultivation (Hochman et al, 2014; Moutinho et al, 2018; Sabiha et al, 2017). Only three studies, by Du et al (2021), Zhang et al (2021), and Zhong et al (2023), evaluate the ecological efficiency of aquaculture industries. Using the Super‐SBM model, Du et al (2021) investigate the ecological efficiency of 18 marine farms in Shandong province and prove that the redundancy of inputs and the deficiency of ecological outputs are major causes of loss of ecological efficiency.…”

“…Of Chinese aquaculture output, freshwater (inland) aquaculture has produced almost 60% (Chinese Academy of Fishery Sciences, 2020). However, fettered by obsolete production methods and constrained natural resources, Chinese freshwater aquaculture is stuck in a high‐cost, low‐productivity pattern that poses a threat to the environment (Zhang et al, 2018; Zhong et al, 2023; Zou & Huang, 2015). For example, farmers usually over‐introduce feeds and fish medicines containing high‐level micronutrients to maximize the freshwater aquaculture production, accelerating the eutrophication of water bodies (Wang, Beusen, et al, 2019; Wang, Sun, & Wang, 2019).…”

Promoting the productivity and environmental sustainability of aquaculture is critical in ensuring its healthy development. This study assesses freshwater aquaculture's technical efficiency and ecological efficiency in China's 19 inland provinces from 2008 to 2019, aiming to reveal its productivity and environmental sustainability status. We employ the three‐stage Data Envelopment Analysis‐CCR (T‐DEA‐CCR) and three‐stage Slack‐Based Measure‐DEA (T‐SBM‐DEA) methods to explore the technical efficiency and the ecological efficiency while accounting for environmental conditions and random errors. The average technical efficiency and ecological efficiency during 2008–2019 are 0.857 and 0.702, respectively, indicating substantial scope for enhancing the productivity and environmental sustainability of China's inland aquaculture. We further investigate the regional development using the club convergence, finding that the provincial‐level technical efficiencies have already achieved population convergence while the ecological efficiencies diverge into two clubs, suggesting that Chinese freshwater aquaculture's productivity and environmental sustainability have different development pathways. Acknowledging the pivotal roles of environmental protection and growers' training in aquaculture's productivity and environmental sustainability, policymakers may institute funding and recognition to foster the adoption of innovative, environmentally responsible practices by operators.

“…From a regional perspective, it was the highest in the western region, followed by the central and eastern regions [20]. However, the DDF model cannot calculate the arbitrary problems of insufficient improvement and poor output disposal [21]. Applying stochastic frontier analysis and the Malmquist index method to estimate the provincial GTFP in China from 2000 to 2016, one study determined that the overall trend was upward, with the highest GTFP in the eastern region and the lowest in the western region [22].…”

Aquatic products are important sources of protein and food consumption, which are pivotal to solving the problem of food shortage. As the world’s largest producer of aquatic products, China’s aquaculture has developed rapidly. However, a large quantity of pollutants has also been generated in the fish farming process, which is detrimental to the sustainable development of China’s aquaculture. Therefore, under double constraints with regard to resources and the environment, fishery development must achieve cleaner production. Measuring green total factor productivity in aquaculture is fundamental to improving aquaculture production efficiency and reducing pollution emissions. This paper investigated the green total factor productivity in China using the SBM-ML method and analyzed the dynamic evolution of fish farming, measuring its change characteristics with regard to time and spatial differences. The results indicated that the total factor productivity indexes of mariculture and freshwater aquaculture in China are 1.050 and 1.060, respectively. Regionally, mariculture in the East China Sea region has the highest green total factor productivity of 1.072, followed by the South China Sea region with 1.056, and the green total factor productivity in the Yellow Sea region is the lowest—only 1.030. The results of the freshwater aquaculture calculations showed the opposite geographical distribution characteristics in China, with the highest in the western region (1.098), followed by the central region (1.046), with the lowest being in the eastern region (1.038). Evidently, both mariculture and freshwater aquaculture have noticeable spatiotemporal heterogeneity. Relevant policy recommendations are provided to improve the green production efficiency of fishery.

“…This holistic approach results in a more robust and objective assessment of the growth of both the green industry and the overall economy [ 31 , 32 ]. Yet, the majority of current research on GTFP predominantly centers around specific sectors, such as manufacturing, aquaculture, agriculture, etc., and a limited number of studies have delved into assessing specific varieties within these industries [ [33] , [34] , [35] ]. Therefore, the novel and rational application of this index to measure the green productivity of Chinese broilers is an innovative effort.…”
