“…A systematic study of efficiency theory was conducted by Farrell in 1957 [ 26 ]. Efficiency evaluation is always expressed as the ratio of an objective’s outputs to inputs at a specific time, from the perspective of management and economics, and has been studied and applied in different fields [ 27 , 28 ]. A DEA model is a specific model of data envelopment analysis, which analyzes the technical efficiency and scale efficiency of decision-making units (DMUs).…”

“…The efficiency measurement of Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) in DEA would be used to evaluate SCC input–output efficiency in China. To measure the construction efficiency of pilots and its influencing factors, the Banker, Charnes, and Cooper (BCC) model, with the assumption of variable returns to scale, was selected to analyze the technical and scale efficiency for the efficiency evaluation system of SCC pilots, as shown in the following equation [ 28 ]:

Sponge city construction (SCC) has improved the quality of the urban water ecological environment, and the policy implementation effect of SCC pilots is particularly remarkable. Based on the data envelopment analysis (DEA) model, this study employed the related index factors such as economy, ecology, infrastructure, and the population of the pilot city as the input, and the macro factors of SCC as the output, to scientifically evaluate the relative efficiency between the SCC pilots in China. Eleven representative SCC pilots were selected for analysis from the perspectives of static and dynamic approaches, and comparisons based on the horizontal analysis of the efficiency of SCC pilots were conducted and some targeted policy suggestions are put forward, which provide a reliable theoretical model and data support for the efficiency evaluation of SCC. This paper can be used as a reference for construction by providing a DEA model for efficiency evaluation methods and thus helps public sector decision makers choose the appropriate construction scale for SCC pilots.

“…Svetlana et al [19] performed an efficiency evaluation of regional environmental management systems in Russia; the results showed that the efficiency of regional environmental management in many Russian regions has great potential for improvement. Wang et al [20] evaluated the efficiency of LED energy enterprises in China using the DEA model. The results revealed that the total technical efficiency of China's LED energy firms has improved, owing to the LED energy enterprises' focus on technology advancement.…”

Vietnam’s textile and garment enterprises make an important contribution to the country with the second largest export turnover. The existence and development of textile and garment enterprises have a significant influence on the socioeconomic development of Vietnam. Currently, Vietnam’s textile and garment industry is facing difficulties caused by the COVID-19 pandemic, along with competition from foreign direct investment (FDI) enterprises. Therefore, it is imperative for managers to assess competitiveness by measuring their past and current performance indicators. This study assesses the performance of Vietnam’s 10 textile and garment enterprises from 2017 to 2020 by combining the DEA–Malmquist productivity index (MPI) and epsilon-based measure (EBM) model. The proposed model considered three inputs (total assets, cost of goods sold, and liabilities) and two outputs (total revenue and gross profit). In addition to showing the best-performing companies from certain aspects during the period (2017–2020), the results show that the EBM method combined with the Malmquist model in the field can be successfully applied. This study is a reference for companies in the textile and garment industry to identify their position to improve their operational efficiency and overcome their weaknesses.

This study investigates the impact of a company's environmental, social, and governance (ESG) activities on its financial performance. The COVID‐19 pandemic has caused unexpected difficulties in the operations of most companies, leading to a significant deterioration in their financial performance. We use empirical analysis to examine whether a company's ESG activities affect its financial performance. We employ the context‐dependent data envelopment analysis (DEA) model to evaluate the performance and provide a benchmark‐learning roadmap for 27 photoelectric companies in Taiwan. We also compare the marketability, innovation ability, and profitability of three sub‐industries: camera modules, optical component lenses, and optical components. Furthermore, we utilize a combination of classical DEA, stratification DEA, measurement of attractiveness, and progress for company evaluation. The results indicate that validating sustainability reports has a positive information effect, and high‐quality Global Reporting Initiative‐based external third‐party confirmed reports possess relatively high credibility, readability, and information value. The content and quality of these reports have an impact on performance. These findings offer insights into the role of ESG activities in the photoelectric industry and can help managers reflect upon and justify their choice to invest in specific ESG activities. Therefore, this research highlights the importance of green operations for firms.
