Abstract:

Identifying the comparative advantages in the cultivation of grain crops is of significant value for optimizing regional planting structures, enhancing the comprehensive benefits of grain cultivation, and thereby ensuring food security. This study is based on the data related to the cultivation of major grain crops in the nine provinces (autonomous regions) of the Yellow River Basin from 2010 to 2022. Utilizing the comparative advantage analysis method, the study measured the spatio-temporal evolution of the comparative advantages of five major grain crops, including rice, wheat, corn, legumes, and tubers. The principal findings indicate that in terms of scale advantages, rice in Sichuan, wheat in Henan and Shandong, tubers in Gansu and legumes in Inner Mongolia are particularly prominent; in terms of efficiency advantages, legumes in Qinghai, Gansu, and Shandong, as well as tubers in Qinghai and Shandong, and corn in Qinghai, are more significant; for comprehensive advantages, rice in Sichuan, corn in Inner Mongolia and Shanxi, wheat in Henan and Shandong, tubers in Gansu, and legumes in Inner Mongolia are predominant; in terms of the temporal changes in comprehensive efficiency, there is a noticeable upward trend for rice in Sichuan and Inner Mongolia, wheat in Qinghai, Shandong and Henan, corn in Sichuan, and legumes in Inner Mongolia. Additionally, the comprehensive index for tubers in Qinghai, Sichuan, Gansu, Ningxia, and Shaanxi has shown a certain degree of growth, indicating a promising development prospect. This study can provide some ideas for the optimization of planting structure and high-quality agricultural development in the Yellow River Basin.
