Agricultural eco-efficiency is a vital indicator for assessing the sustainability of agriculture. Conducting evaluations of agricultural eco-efficiency can provide critical information for policymaking, resource allocation, and the advancement of agricultural sustainable development. While there exists a substantial body of research on the evaluation of agricultural eco-efficiency, its influencing factors, and improvement paths, there remains a paucity of systematic reviews, evaluations, and prospective analyses in this area. This study employed the literature search method to analyze relevant scholarly articles. Chinese literature was sourced from the CNKI (China National Knowledge Infrastructure) database, while international literature was obtained from the Web of Science database. The literature search was conducted from 1998 to 2023. The study reviewed the progress of research on agricultural eco-efficiency and outlined the challenges and prospects that lie ahead. The findings of this study indicate that the primary challenges in the field of agricultural eco-efficiency research include refining the evaluation system, integrating macro and micro influencing factors, and ensuring the suitability of models employed. In the future, the research could expand in areas such as deepening the application of artificial intelligence technology in evaluation methods, clarifying the driving factors of agricultural eco-efficiency, and promoting the green transformation of agriculture. This study provides a comprehensive systematic review and could provide critical information for related research expansion.

Table 1 Evaluation framework |
Evaluation framework | Framework application | Evaluation areas | Literature sources |
---|---|---|---|
Agricultural economic value—Positive and negative consumption of environmental resources | Single ratio method | Cities of Jiangxi Province, etc. | Wang et al. (2016); Huang et al. (2018) |
Actual environmental load emissions—Ideal environmental load emissions | Life cycle assessment | Cities of Hubei Province, etc. | Wang et al. (2018); Huang et al. (2022) |
Production function—Combination of input factors—Optimal output | Stochastic frontier analysis | Cities of Jiangxi Province, etc. | Gu and Zhu (2020); Ji and Shang (2021) |
Population, social and economic activities—Ecological environment carrying capacity | Ecological footprint analysis | Guizhou Province, etc. | Hong and Quan (2012); Wang and Lin (2021) |

Table 2 Evaluation methods of agricultural eco-efficiency |
Evaluation methods | Application areas | Formulae and explanation |
---|---|---|
Single ratio method | Agricultural economic development | where, AE: agricultural eco-efficiency; EV: economic value of agricultural products; C: consumption of agricultural products; NE: negative environmental effects of agricultural products; PE: positive environmental effects of agricultural products. |
Life cycle assessment | Agricultural energy consumption and waste discharge | The life cycle assessment (LCA) method evaluates the use of resources and materials, as well as the emissions of environmental impacts, by identifying and quantifying them. It assesses the impacts of these inputs and emissions, and evaluates and explains opportunities for environmental improvement. The LCA process consists of four specific steps: 1) Setting evaluation goals and scope; 2) Inventory analysis; 3) Impact assessment and analysis; 4) Interpretation of life cycle results. |
Stochastic frontier analysis | Calculation of agricultural eco-efficiency | where, yit: the output of i in period t; pit: the production factors invested by i in period t (t is the time); rit: the random error term of the equation; oit: another error term of the equation. |
Ecological footprint analysis | The impact of human agricultural activities on the environment | where, ef: per capita ecological footprint; ai: per capita biological production area occupied by i substance; rj: equivalence factor; ci: per capita consumption of substance i; pi: world average production capacity of substance i; i: types of substances consumed; j: type of biological production area. |
Data envelopment analysis | Calculation of agricultural eco-efficiency | where, h0: efficiency value of evaluation unit; μT: weight of a certain investment; vT: weight of a certain output; xj: the input vector of j; yj: the output vector of j. |

Reducing fertilizer application | Wu et al. (2012) | |
Excessive redundancy of non-expected outputs | Zhang et al. (2014) | |
Spillover effect of agricultural production | Hou et al. (2021) | |
Fertilizer efficiency promotion policies | Liu et al. (2019) | |

The level of integration development of the tertiary industry | Wang and Zhou (2021) | |
Agricultural planting structure | Zeng et al. (2021) | |
The level of sustainable development of agricultural economy | Huang and Liu (2018) |
