Summary
This panel study of 30 Chinese provinces (2013–2022) constructs a multidimensional Grain Productivity Quality Index and uses difference-in-differences methods to estimate the causal effect of new energy development on grain production outcomes. A 1% increase in new energy development raises GPQI by 0.41%, with heterogeneous effects by energy source (solar and nuclear positive; hydropower and wind insignificant) and regional context. The findings suggest energy transition can support sustainable grain production, though effects vary substantially by institutional and governance conditions.
Regional applicability
This study is specific to China's energy and agricultural policy context, dual-carbon goals, and provincial-level governance structures. Findings may have limited direct applicability to United Kingdom farming systems, though the conceptual framework linking energy transition to food production resilience and the importance of regionally differentiated policy design could inform UK approaches to integrating renewable energy deployment with food security objectives.
Key measures
Grain Productivity Quality Index (GPQI) via entropy-weight method; new energy development intensity; provincial-level panel data (2013–2022); heterogeneity analysis by spatial, temporal, policy, economic and financial development levels
Outcomes reported
The study measured effects of new energy development on a multidimensional Grain Productivity Quality Index (GPQI) incorporating technological efficiency, digitalization, green-input adoption, production integration, and inclusiveness across Chinese provinces. Results showed heterogeneous impacts by energy type and regional context.
