“…The GDE of marine fish culture in China was 0.9529, which was in an inefficient state. Compared with mariculture (GDE = 0.7140) (Wang and Ji, 2017) and agriculture (GDE = 0.6650) (Wu et al, 2022) in China, the GDE of marine fish culture was higher. This better performance of marine fish culture may result from its smaller scale and less complex environment than those of mariculture and agriculture.…”

“…It is more convenient to distinguish the difference in efficiency values than the SBM model (Meng and Qu, 2022). In previous studies, the Super-SBM model was widely used in industry, agriculture, energy, and other fields (Gökgöz and Erkul, 2019;Cui et al, 2020;Li and Ouyang, 2020;Khan et al, 2021;Wu et al, 2022). Therefore, in our study, we used the Super-SBM model to measure the GDE of marine fish culture.…”

“…In some cases, some DMUs are simultaneously efficient when evaluating efficiency. To establish a reasonable efficiency evaluation method, we apply the super-SBM model with undesirable outputs based on the previous studies (Andersen and Petersen, 1993;Tone, 2004;Li et al, 2013;Zhang et al, 2019;Zhao et al, 2020;Khan et al, 2021;Wu et al, 2022). This model is described as follows: (5)…”

“…From the existing perspective, research on GDE has mainly focused on green growth efficiency (OECD, 2009;World Bank, 2010;Kim et al, 2014;Ahmad and Wu, 2022), sustainability (UNDP, 1990;Prescott-Allen, 1995;Beijing Normal University., 2010;Sustainable Development Strategy Research Group and Chinese Academy of Sciences (CAS), 2011;UNEP, 2014;Schulte and Knuts, 2022), and ecological economic efficiency (Schaltegger and Sturm, 1990;WBCSD, 2000;UNESCAP, 2009;Shen et al, 2020;Zhu et al, 2022). The GDE of mariculture, marine economy, and agriculture evaluations have also gained some achievements for achieving the sustainable development goals, and stochastic frontier analysis (SFA) and data envelopment analysis (DEA) were mainly adopted in these studies (Wang and Ji, 2017;Cui et al, 2020;Ye et al, 2021;Wu et al, 2022). Although the above studies provided many illuminating results, the research on the GDE of marine fish culture is still very limited.…”

Green development efficiency (GDE) is an important criterion for measuring the level of green development. GDE considers not only economic development efficiency but also environmental costs. In China, marine fish culture, as one of the pillar industries of mariculture, promotes green development and industrial transformation and upgradation. Based on data from the field surveys of marine fish farmers (2017–2019) and the China Fishery Statistical Yearbook (2018–2020), this study establishes an evaluation index system and uses the super-slack-based measure model (Super-SBM) to evaluate the GDE of marine fish culture. The results show that the average GDE of marine fish culture in China was 0.9529, which was in an inefficient state. As for culture species, golden pompano (Trachinotus ovatus) and cobia (Rachycentron canadum) were the two species farmed in an efficient state, with a GDE of 1.2107 and 1.0659, respectively. Regarding culture modes, green modes (offshore cage aquaculture, industrial recirculating aquaculture, and engineering pond aquaculture) were in an efficient state, with a GDE of 1.2310, 1.0827, and 1.0401, respectively. Traditional modes (industrial flow-through aquaculture, ordinary cage aquaculture, and ordinary pond aquaculture) were in an inefficient state, with their GDE being 0.9884, 0.8746, and 0.8248, respectively. Green modes have higher GDE than traditional modes. In contrast, the production and culture areas of green modes were less than those of traditional modes because the profits of the same species in green modes were lower than those in traditional modes. The results of this study present an objective assessment of the GDE of marine fish culture in China and provide valuable insights for analyzing the mechanisms to improve the GDE of marine fish culture.

“…In recent years, in accordance with the decisions and arrangements of the Party Central Committee and the State Council, all localities have carried out in-depth e orts to reduce the burden of homework and o -campus training (hereinafter referred to as "double reduction") for students in the compulsory education stage [1]. But one of the most prominent problems in compulsory education now is that primary and secondary school students are too burdened, and the problems of short-sightedness and utilitarianism have not been fundamentally resolved [2].…”

Children are the hope of building a powerful, modern-socialist state. In recent years, all social classes have paid more and more attention to children’s enlightenment education, and the country began to implement the double reduction policy. As the main place for children to live and grow, the community has the responsibility and obligation to conduct the education of children. Work and effective development and utilization of community education resources can greatly meet the needs of children’s growth, help children develop good behavior habits, and lay a solid foundation for future education. Through the experimental survey results, this paper discusses the theoretical basis for the development and utilization of community children’s education resources under the dual emission reduction policy, puts forward the corresponding development principles, and analyzes the main strategies to improve the efficiency of social education.
