Spatio-temporal evolution and regional heterogeneity in the efficiency of agricultural non-point source pollution control within the Chaohu Lake Basin
This study employs panel data from 17 counties (districts) within the Chaohu Lake basin spanning 2016-2023. It utilises the SBM-DDF model to conduct a static measurement of agricultural non-point source pollution control efficiency. Building upon this foundation, it further employs the Global Malmquist-Luenberger (GML) index to perform a dynamic decomposition of this efficiency. Additionally, regional heterogeneity is examined across the upper, middle, and lower reaches of the Chaohu Lake basin. Research findings reveal: (1) Agricultural inputs within the Chaohu Lake basin exhibit widespread redundancy, with excessive application of chemical fertilizers and pesticides constituting the core issue, alongside low utilisation efficiency of labor, machinery and irrigation resources. (2) Basin-wide governance efficiency demonstrates cyclical fluctuations characterised by 'policy effectiveness - efficiency decline - adjustment recovery', with weak synergies between technological advancement and management efficiency severely constraining overall governance efficacy. (3) Significant regional heterogeneity exists: upstream areas exhibit high redundancy in labor, machinery, and pesticide inputs alongside dual deficiencies in technology and management; midstream regions demonstrate efficient land use and the lowest reliance on chemical pesticides, yet suffer from unstable policy implementation; downstream areas face prominent redundancy in fertilizer and irrigation, coupled with structural imbalances in technology and management. Based on these findings, the following recommendations are proposed:
Key Takeaways for Enterprise Leaders
The study reveals widespread redundancy in agricultural inputs, especially chemical fertilizers and pesticides, leading to low utilization efficiency of labor, machinery, and irrigation resources. Governance efficiency in the Chaohu Lake Basin shows cyclical fluctuations, marked by 'policy effectiveness - efficiency decline - adjustment recovery', severely constrained by weak synergy between technological advancement and management. Regional heterogeneity is significant: upstream areas have high input redundancy and dual deficiencies in technology and management; midstream regions show efficient land use and low pesticide reliance but suffer from unstable policy implementation; downstream areas have prominent fertilizer and irrigation redundancy with structural imbalances in technology and management. These insights are crucial for targeted strategies to foster green agricultural transformation and efficient pollution control.

Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
- The study integrates SBM-DDF and GML index models for static efficiency measurement and dynamic decomposition of agricultural non-point source pollution control efficiency.
- The SBM-DDF model addresses non-radial slack and undesired outputs, improving efficiency measurement accuracy.
- The GML index resolves intertemporal comparison issues by using a global production frontier, enabling decomposition into technical efficiency (EC) and technical progress (TC).
- Direction vectors are defined to elucidate system coupling mechanisms, allowing for optimization according to current scale proportions or full-sample range benchmarks.
- Agricultural inputs exhibit widespread redundancy, with excessive application of chemical fertilizers and pesticides being the core issue.
- Utilization efficiency of labor, machinery, and irrigation resources remains low across the basin.
- Governance efficiency shows cyclical fluctuations ('policy effectiveness - efficiency decline - adjustment recovery'), severely constrained by weak synergy between technological advancement and management.
- Significant regional heterogeneity exists, with distinct patterns of input redundancy and technological/management deficiencies across upstream, midstream, and downstream areas.
- Implement targeted strategies to reduce excess capacity based on slack variables, focusing on regulating fertilizer and pesticide application, and promoting ecological agricultural technologies.
- Establish an efficiency-oriented long-term governance mechanism, deepening the integration of technology and management, and incorporating GML Index and coordination levels into policy evaluation.
- Implement zoned collaborative governance strategies with differentiated approaches for upstream (provincial green agriculture compensation funds), midstream (dual assessment system with River/Lake Chief System), and downstream (irrigation district water user associations) areas.

Case Study: Impact of Policy Intervention on Governance Efficiency (2018)
Scenario: In 2018, strong intervention policies like the 'Opinions on Accelerating the Development of a Green and Beautiful Chaohu Lake' and 'Ten Major Wetland Restoration Projects' were implemented. This led to a significant increase in the mean GML Index (1.0640), demonstrating that concentrated policy initiatives can substantially enhance basin-wide management effectiveness within a short timeframe. However, the period also saw high volatility in efficiency scores across districts, indicating uneven distribution of policy benefits.
Outcome: While policy interventions showed short-term effectiveness, long-term sustainability requires deepening the synergy between technology and management. The observed 'policy effectiveness - efficiency decline - adjustment recovery' cycle highlights the need for continuous, adaptable governance mechanisms rather than one-off interventions.
Enterprise Relevance: This illustrates that even with significant investment, without integrated technological and managerial strategies, efficiency gains can be short-lived or unevenly distributed. Enterprises should aim for holistic transformation, not just isolated policy compliance.

Your AI Transformation Roadmap
A strategic phased approach for integrating advanced AI solutions derived from research insights into your enterprise operations.
Phase 1: Diagnostic & Strategic Alignment
Conduct a detailed slack variable analysis at the sub-basin level to pinpoint precise areas of input redundancy (fertilizers, pesticides, labor, machinery, irrigation). Align these findings with current agricultural practices and policy frameworks to identify immediate intervention points. Establish a cross-functional task force involving agricultural specialists, environmental scientists, and AI/data experts.
Phase 2: Technology & Management Integration Pilot
Pilot precision agriculture technologies (e.g., drone variable-rate fertilization, intelligent irrigation systems) in high-redundancy areas, integrating them with updated management protocols. Implement a 'Technology-Management Synergy Enhancement' initiative in a selected district (e.g., Feixi County for 'technical silos' or He County for 'management compensation') to develop best practices for combining technological progress with improved operational efficiency.
Phase 3: Zoned Collaborative Governance Framework
Develop and implement differentiated governance strategies for upstream, midstream, and downstream regions. For upstream, focus on green agriculture compensation and ecological infrastructure. For midstream, establish a dual assessment system linking water quality to GML index targets. For downstream, create water user associations and promote smart irrigation with water quota trading. Establish a basin-level joint governance conference for shared responsibility and incentivization.
Phase 4: Monitoring, Evaluation & Adaptive Adjustment
Establish a robust monitoring system using real-time data on input usage, pollution emissions, and governance efficiency (GML Index, coordination levels). Regularly evaluate the impact of interventions and adapt strategies based on performance data. Institutionalize continuous learning loops to ensure long-term sustainability and responsiveness to environmental and economic changes.
