Summary
Digital technology integration in agriculture is key for food security, requiring collaboration between governments, service providers, and producers. Policy should focus on incentives and support tailored to regional needs for optimal outcomes.
Area of Science:
- Agricultural Economics
- Digital Agriculture
- Food Security Policy
Background:
- Digital technology integration is crucial for national food security strategies.
- Effective digital agriculture adoption depends on local government, service provider, and producer coordination.
Purpose of the Study:
- To analyze the evolutionary game dynamics between local governments, digital agriculture service providers, and grain producers.
- To identify conditions for tripartite collaboration and steady-state transitions in digital agriculture adoption for food security.
Main Methods:
- Construction of a three-party evolutionary game model.
- Inclusion of variables like digital empowerment, technology accessibility, subsidies, and government incentives.
- Numerical simulations using calibrated benchmark parameters and sensitivity analysis.
Main Results:
- Identified four evolutionary scenarios, including ideal tripartite collaboration and low-level equilibria.
- China's major grain regions show "technologically effective but weak profitability" and a drive towards collaboration.
- Key drivers identified: digital empowerment, producer subsidies, provider costs, and government incentives.
Conclusions:
- Policy should adopt differentiated, coordinated approaches rather than single instruments.
- Integrate demand-side incentives, supply-side support, and government performance assessments.
- Facilitate knowledge transfer for sustainable digital technology adoption in agriculture.
