Investigating Contribution Factors of Grain Input to Output Transformation for the Inner Mongolia Autonomous Region in China

Inner Mongolia Autonomous Region (IMAR) has become the sixth-largest grain-producing province of China, contributing 5.6% total national grain output in 2021. Grain production increased by around 821% from 1980 to 2019. The contributions structure adjustment, sown area, and yield increase was analyzed for IMAR. For yield, Cobb–Douglas function estimated, analyze contribution agricultural inputs (fertilizer, irrigation, seed, pesticide, agriculture film, machinery operation) impact natural hazards on yield. Results our study showed that IMAR 81.40 × 104 t 0.11 t·ha−1 annually grain-crop area 73.65 103 ha annually, maize constitutes 16.82% 55.30% 1980–2019. In IMAR, adjustment can explain 54.06%, 33.31%, 12.63% production, respectively, input per unit fertilizer, other (seed, mechanical operation inputs) 362.16%, 259.66%, 405.55%, 1981 2019, which contributed 160.44%, 15.06%, 53.13% main cereal (maize wheat) while decrease comprehensive loss rate agrometeorological 7.76% Technologies such as water-saving high-efficiency fertilizer application, agrometeorological-hazards mitigation measures should be adopted future considering stable environmental resource constraints.
