Land use transitions increasingly hinge on how governance arrangements shape resource use efficiency and knowledge diffusion in agricultural systems. Collective irrigation, as a key institutional form of water governance, has been widely promoted to improve irrigation performance, yet its potential linkages with peer effects in agricultural production remain insufficiently understood. Using plot-level panel data from Jiangsu Province, China, for 2015 and 2019, this study examines how peer effects and collective irrigation affect the technical efficiency of rice production. A time-varying stochastic frontier production function is employed to estimate technical efficiency, while a linear-in-means model is used to capture peer effects and compare their effects across different irrigation types. The results indicate that peer effects play a significant role in improving technical efficiency in rice-growing areas. These effects are more pronounced under collective irrigation arrangements. Moreover, peer effects under collective irrigation are stronger in villages without public technology extension services, among farmers with lower grain production capacity or without off-farm employment, and on smaller plots. Mechanism analysis indicates that peer effects under collective irrigation operate partly through input decisions, especially pesticide use. Overall, the findings highlight the importance of considering both peer interactions and irrigation institutions when improving agricultural production efficiency. Full article

Achieving sustainable rice production is essential for food security, rural livelihoods, and the resilience of rice-based food systems that supply raw materials to the food processing industry. Improving technical efficiency (TE) at the farm level is a key pathway to reduce resource use and environmental pressures per unit of output while ensuring a stable supply of high-quality rice for downstream processing and value-added products. Drawing on micro-survey data collected in 2021–2022 from 455 rice farmers selected through a multi-stage sampling strategy in Jiangsu Province, China, this study investigates how agricultural productive services (APSs) affect stage-specific technical efficiency along the production process and discusses the implications for sustainable rice production and the rice-based food industry. We apply a stochastic frontier production function to estimate overall and stage-specific TE and examine the effects of different APS combinations for land preparation, sowing, fertilization, pest control, and harvesting. The results show that overall participation in APSs significantly improves rice farmers’ TE. Stage-specific analysis reveals that APSs in land preparation, sowing, and harvesting are associated with higher TE, supporting more sustainable use of machinery and labor, while APSs for fertilization and pesticide application do not consistently improve TE and may reflect potential overuse of chemical inputs. Multi-stage service combinations that include both production and pest-control operations can further enhance TE. These findings suggest that well-designed APSs can contribute to sustainable intensification and low-carbon transformation of rice production, thereby strengthening the sustainability of rice-based food systems. Policy interventions should guide APS providers and farmers toward integrated, precision-oriented, and environmentally friendly service packages that support both farm-level efficiency and the sustainability goals of the broader food industry.

The olive flounder (Paralichthys olivaceus) is a significant aquaculture species in Korea, yet production has stagnated due to rising costs, environmental pressures, and shifting consumer preferences. Enhancing farm efficiency is critical not only for economic viability but also for environmental sustainability, as efficient production reduces resource waste, lowers feed inputs, and minimizes the carbon output of aquaculture operations. This study estimated the production function and efficiency of olive flounder farms in Korea using stochastic frontier analysis, drawing on survey data collected directly from producers. Results indicate that the Cobb–Douglas model is more suitable than the translog model for empirical analysis. The average farm efficiency was 0.38, with the lowest recorded efficiency at 0.13. Key determinants of production efficiency included fry quality, workforce size, and feed management. Regional differences were also observed in the technical inefficiency factor. By identifying inefficiencies and management gaps, this study highlights opportunities to enhance resource use efficiency, reduce environmental and economic waste, and promote more sustainable practices. The findings provide insights for policymakers and farm managers seeking to strengthen both the profitability and sustainability of the Korean olive flounder aquaculture industry. Full article

This article is devoted to the study of the possibilities for improvAzing the quality of energy management systems adopted at open-pit mining enterprises in the Russian Federation. The main idea of the work is to apply stochastic boundary value analysis methods using the production function for individual and integral estimates of the performance of energy-consuming objects when performing various types of technological work. It is shown that mining enterprises are experiencing problems in the field of rational energy consumption due to the lack of strictly formalized ways to determine the frontiers of the efficiency value of the parameter of specific energy consumption (SEC). A justification is given for the need to apply stochastic frontier analysis (SFA) methods and use the Cobb–Douglas production function to account for the nonlinearity and stochasticity of the operating conditions of energy-consuming mining objects. The results of a statistical analysis of the data on the operation of EKG-10 excavators at operating enterprises in Siberia are presented, as well as an assessment of their energy efficiency using the adopted approach based on planning the target value of SEC. The results of computational experiments on constructing an energy efficiency model using the SFA/Cobb–Douglas function for various data segmentation options are presented. Computational experiments have been conducted to compare variants based on the Cobb–Douglas production function and translog function with semi-normal and exponential distribution forms for the same data set. A comparative assessment is given of the approaches to the complex analysis of activities adopted at enterprises and proposed in this study, characterizing potential hidden energy losses in the range from 4.53% to 20.73%.

This article estimates the impact of government subsidies on productivity growth in South Africa, joining the ongoing debate among economists regarding the effectiveness of subsidies as a driver of industrial productivity. While some argue that subsidies address market failures, facilitate R&D, and improve efficiency, others criticise the attendant dependence, which reduces the incentive for industries to operate efficiently. This article contributes by examining the specific channels—efficiency and technical changes—through which subsidies affect productivity in South Africa. The analysis is based on a panel dataset comprising 64 three-digit industries observed between 1993 and 2023. Estimation is performed through an endogeneity robust panel stochastic frontier model, which treats subsidies as both an inefficiency driver and a technology variable. An additional estimation approach is proposed integrating the true fixed effects with a control function in a bid to account for both unobserved heterogeneity and idiosyncratic endogeneity. The results show that subsidies are detrimental to productivity, particularly through stifling technological progress. This result supports the view that subsidies reduce the incentive for beneficiaries to innovate. This evidence calls for a reevaluation and a possible restructuring of subsidy programmes in South Africa in a bid to mitigate their adverse effects on industrial productivity. Full article

Climate warming poses a significant threat to China’s national food security as grain production encounters the daunting challenge of climate change. Thus, promoting the shift of agriculture toward climate-smart practices has become an inevitable choice. This study investigated climate-smart agriculture (CSA) practices using agricultural and environmental indicators that affect the technical efficiency of grain farming in Northeast China. The study employs the stochastic frontier analysis approach to estimate the efficiency of the production function and highlight the significant factors that affect efficiency. The entropy weight method was also used to analyze the climate-smart agricultural development index (CSA-DI) and climate-smart balanced development index (CSA-BDI) in Northeast China. The provincial panel data from 1980 to 2017 revealed an increasing trend for the CSA-DI and CSA-BDI. Although the region has achieved initial results in systematicity and coordination, there is still room for improvement in food security and climate change adaptation. Based on these results, this study proposes policy recommendations for CSA technologies and the promotion of comprehensive projects to endorse climate-smart agriculture for regional shared benefits and responsibilities.

This article presents an estimation of a stochastic frontier model using a translogarithmic production function to identify the impact of production factors—labor and capital—along with CO₂ emissions and technical progress on the value added of the manufacturing sector in North American countries over the 1984–2022 period. The model also provides estimates for technical efficiency, scale efficiency, and technological change, allowing for a comparative analysis of these indicators’ evolution within the manufacturing sectors of Canada, Mexico, and the United States. The findings indicate that capital exerts the strongest influence on manufacturing value added, followed by labor. CO₂ emissions exhibit the anticipated negative effect on the sector’s value added. Notably, the average technical efficiency of Mexico’s manufacturing sector is higher than that of Canada and the United States over the studied period. Regarding technological change, the United States demonstrates the highest values, followed by Canada, with both nations displaying an upward trend throughout the years, while Mexico shows a declining trend in this indicator.

Rice is one of the primary staple foods in Nepal, and there has been a notable increase in the production of this crop over the past ten years. Nonetheless, there appears to be a growing tendency to import rice. The plain region (Terai) of Nepal produces more than two-thirds of the country’s total rice output, with the highest productivity found in Madhesh Province. However, because of the limited knowledge regarding the technical aspects of rice production, commercial rice growers are facing challenges in using resources to produce output as effectively as possible. There is a pressing need to maximize production based on a limited number of inputs. Thus, this study aimed to examine the technical efficiency of rice farmers and the factors affecting technical inefficiency in the Parsa district of Nepal. This study area is the major domain of the Prime Minister Agriculture Modernization Project (PMAMP), which supports farmers with necessary agricultural inputs, infrastructure development, and innovative practices. Data were collected from 215 rice farmers using multistage purposive sampling and were subjected to a Cobb–Douglas stochastic frontier production function. The results showed that rice producers had a technical efficiency of 0.862. Age and off-farm activities were found to significantly influence the technical efficiency of rice farmers. The technical efficiency of rice producers could be enhanced using a project approach, such as the PMAMP. It is important for the government to implement innovations and technologies in farms with the participation of older farmers because their ability to adapt to novel techniques and technologies is better than that of young farmers. Youth generally prefer off-farm employment opportunities, so domestic investment in agriculture should be promoted to make this sector more appealing. Further, policies and programs focusing on pooling small rice fields and subsidizing the price of tractors will help improve the yield of rice. Full article

Revealing the level of cultivated land use efficiency and its influencing factors in the northern agro-pastoral ecotone from the perspective of population contraction can provide a decision-making reference for ensuring national food security and promoting the implementation of rural revitalization strategies. In this paper, using the stochastic frontier production function and a Tobit regression model, we reveal the current situation of rural population shrinkage in the agro-pastoral ecotone in northern China and the spatial and temporal evolution characteristics of cultivated land use efficiency, and identify influencing factors based on the perspective of “human–land”. The results show the following: (1) The rural population in all provinces and counties in the agro-pastoral ecotone in northern China showed a continuous loss trend. The southwest was a hot spot area for rural population reduction, and the northeast was a cold spot area for rural population reduction. (2) During 2000–2020, the cultivated land use efficiency in the agro-pastoral ecotone in northern China showed a fluctuating upward trend, rising from 0.595 in 2000 to 0.754 in 2020. Spatially, the cultivated land use efficiency in the agro-pastoral ecotone in northern China showed the characteristic of being higher in the northeast and lower in the southwest, and the cultivated land use efficiency in some counties in the central and southwestern parts showed a downward trend. (3) The cultivated land use efficiency in the agro-pastoral ecotone in northern China is comprehensively affected by multiple factors. The following factors were determined, presented in descending order of the absolute value of influence degree: proportion of the population over 65 years old > multiple cropping index > proportion of cultivated land area > proportion of rural population > average years of education > population change rate. Based on these results, this paper puts forward measures to improve cultivated land use efficiency in the agro-pastoral ecotone in northern China from the perspective of population shrinkage, so as to provide references for ensuring national food security and promoting rural revitalization.

Enhancing the efficiency of fertilizer utilization and advancing fertilizer reduction efforts constitutes a pivotal initiative for augmenting the quality and productivity of the citrus industry; this constitutes an indispensable prerequisite for attaining green and sustainable development. Utilizing panel data from seven prominent mandarin-producing regions and seven prominent tangerine-producing regions in China spanning from 2002 to 2022, this study employed the stochastic frontier analysis (SFA) method to develop a translog production function model for precisely measuring the fertilizer use efficiency for mandarins and tangerines. Employing the calculated optimal fertilizer use rates, we further ascertained the fertilizer reduction potential for mandarin and tangerine; then, we estimated the associated carbon emission reduction potential within these key citrus regions. The research revealed the following findings: the overall level of citrus fertilizer use efficiency in China is comparatively low, with the mean values for mandarin and tangerine fertilizer use efficiency being merely 0.4403 and 0.3887, respectively, indicating substantial room for improvement by approximately 60%; substantial potential exists for decreasing fertilizer use in China’s citrus industry, with average reduction potentials of 66.27% for mandarins and 64.83% for tangerines, signifying a notable redundancy in fertilizer application within major citrus-producing areas. The magnitude of carbon emission reduction potential through the diminution of citrus fertilizer use is tremendous. When optimal fertilizer rates are applied, the average carbon emission reductions resulting from fertilizer reduction in mandarins and tangerines amount to 815.8681 kg/hm² and 602.3551 kg/hm², respectively. The average carbon reduction potential for mandarins and tangerines reach levels of 55.9673% and 61.1299%, respectively, both surpassing the threshold of 55%. Significant differences exist in the technical efficiency of fertilizer input, reduction potential, and carbon emission mitigation potential among major citrus-producing regions. Citrus orchards in Guangdong exhibit higher potential for fertilizer reduction but demonstrate a relatively low level of technical efficiency. In contrast, Hunan Province shows an opposite trend, necessitating the development of region-specific strategies. Therefore, to minimize citrus fertilizer use and augment the technical efficiency of citrus fertilizer, it is imperative to comprehensively integrate and promote the “three new” technologies aimed at reducing fertilizer use and enhancing its efficiency within the citrus industry; implement a regional coordinated development strategy for citrus fertilizer reduction; and intensify policy guidance, publicity, and training efforts related to citrus fertilizer reduction, efficiency enhancement, and carbon emissions reduction.

Farm overinvestment is highly dangerous in how it affects productivity and profitability. Therefore, it imperatively needs to be measured in the context of investment support offered under the Common Agricultural Policy. In turn, technical efficiency is one of the best methods for measuring farm investment. This paper analyzes the technical efficiency of 3273 Polish farms based on unpublished FADN (Farm Accountancy Data Network) data from 2010–2019. The purpose of this study was to indicate the level of, and changes in, technical efficiency of Polish farms in function of their investment levels, with particular emphasis on overinvested holdings. Technical efficiency was examined using stochastic frontier analysis (SFA). The study proved a decline in technical efficiency in underinvested farms and in those affected by absolute overinvestment (i.e., ones where the assets-to-labor ratio grows while labor productivity drops).

In the context of China’s large country with small farmers, agricultural socialized services are regarded as an important way for small farmers to organically connect with modern agriculture and provide ideas for improving agricultural green total factor productivity (AGTFP). Based on data from 1066 farmers from the China Land Economy Survey (CLES), this paper takes net carbon sink as the environmental output variable, adopts the Cobb–Douglas production function for stochastic frontier method estimation, and measures the AGTFP based on the stochastic frontier analysis method with an output-oriented distance function. At the same time, through the construction of intermediary effect and regulatory effect models, it empirically analyzes the impact and mechanism of agricultural socialized services on farmers’ AGTFP from the perspective of factor allocation. The study found that agricultural socialized services not only significantly promote AGTFP, but also that the effect of AGTFP improvement is more significant as the degree of participation in agricultural socialized services increases. The main results have passed a series of robustness tests. Further research found that agricultural socialized services promote the improvement of AGTFP through the intermediary role of improving the scale of farmland and the level of agricultural green technology adoption. Off-farm employment of the rural labor force has a positive regulatory effect between agricultural socialized services and AGTFP. Therefore, it is recommended to further play the role of agricultural socialized services in optimizing the allocation of production factors and to motivate agricultural socialized service organizations to provide multiple green production services for farmers through policy support or subsidies, enhance the service capacity of agricultural socialized service organizations, and provide precise services by fully considering the differences in the endowment of production factors among farmers, as well as take multiple measures and make solid and steady progress in promoting the sustainable development of agriculture.

Debt is a fundamental component of modern economic systems. It serves as a source of financing for government, business, and individual projects. Many earlier studies concentrated on the direct relationship between debt and economic performance using different econometric methodologies. This work investigates the effect of debt on production efficiency, extracted from the estimated production function. Unlike previous econometric approaches, we employ a production stochastic frontier analysis (SFA) on data for 18 OECD countries spanning from Quarter 1, 2015, to Quarter 3, 2021, to capture the short-run effect of debt on the production efficiency and, thus, output growth. The results show that, in the short run, as debt increases by $1 billion, efficiency increases by 0.04%. Additionally, we found that the most indebted countries are the most efficient countries. In our sample, those were the UK and France. Furthermore, the average efficiency for the 18 OECD countries was 70.07. Full article

Over the past three decades, China has shifted from a relatively immobile society to one where rural migrant workers are dispersed throughout urban areas, resulting in significant changes in rural family structure. Previous studies have tended to approach migrant workers as homogeneous groups within families. In contrast, our attention turns to the diversity among individuals and the complex interactions within families. Based on a survey of rice farmers in five provinces of China, this study aims to explore the heterogeneous impact of changes in rural family structure on the single-factor (i.e., land, labor, and capital) productivity and technical efficiency (TE) of rice production. Methodologically, we calculated the productivity indicator through the Cobb–Douglas production function. Following this, a one-step stochastic frontier approach (SFA) was employed to assess the production frontier and estimate inefficiency. To address self-selection bias in family migration behavior, we applied the propensity score matching method (PSM). The results reveal that significant outcomes are observed only with certain types of changes in rural family structure. The production decisions of rural families are influenced by the migration regions of their family members. Compared to non-migrating families (NM), families with couples’ joint migration outside the province show higher single-factor productivity and TE. We used multiple approaches to examine the results and came to similar conclusions. Therefore, enhancing social security measures and employment opportunities for migrant workers, with specific attention to supporting migrant couples, can have a positive impact on sustainable urban and rural development, as well as food security.

In the digital transformation era, digitalization integrates deeply into production, bolstering output efficiency and economic value. Through stochastic frontier analysis (SFA), this research positions digitalization as an input in the production function, dissecting its elasticity impact on capital, labor, and output. The effect of digitalization on total factor productivity change (TFPC) is explained by comparing TFPC with and without digitalization. Findings reveal that digitalization’s integration into economic growth displays a U-shaped trajectory, with initial productivity setbacks transitioning to long-term benefits as industries adapt. The periodic complementarity and substitution between digitalization and labor, along with a weak substitution relationship with capital, illustrate that, as a production factor, digitalization dynamically interacts with other factors, both complementing and substituting them. This dynamic interplay highlights the intricate role that digitalization plays within the production function. Furthermore, digitalization has played a crucial role in China’s TFP growth, which also highlights the lack of other technological progress. Meanwhile, the pace of digital transformation presents scalability challenges, evident in the fluctuating scale efficiency change (SEC). Policymakers are advised to address these early stage challenges through supportive measures, ensuring smoother digital transitions. Concurrently, industries should embrace this non-linear transformation, emphasizing adaptability to maximize digitalization’s long-term advantages. Full article
