In the context of a new round of grain production capacity improvement,aimed at reaching 100 billion catties by 2030,it is of great significance to reveal the evolution law of the major grain production performance and explore the factor sources driving this performance in the process of ensuring the sustainable improvement of grain output and promoting the high-quality development of the grain industry.This study focused on the three major grain crops,namely rice,wheat,and corn,and constructed an SBM directional dis-tance function model within the framework of data envelopment analysis.It also comprehensively measured China's grain production performance and factor performance from 2002 to 2021 by using the Luenberger productivity index,and explored the factor sources of the production performance of China's three major grain crops from the perspective of factor decomposition.The results showed that:① During the sample period,the production performance of the three major grain crops showed a significant improvement trend,with the most prominent improvement in the main grain-producing areas.The productivity of rice,wheat,and corn increased by 21.86%,24.35%,and 18.68%,respectively.② The growth of the production performance of the three major grain crops was primarily attributed to improved labor productivity,and the slowdown in labor productivity growth was the main reason for the decline in production perfor-mance growth.③ Technological progress was the primary driving force behind the improvement in the production performance of the three major grain crops,with technological progress in rice always relying on the factor of labor,a shift from land to labor in wheat,and a shift from labor to capital in corn.To meet the goals in the new round of grain production capacity improvement,we should endeavor to improve the production factor performance and overall performance by stimulating grain farmers' enthusiasm,accelerating agricultur-al science and technology innovation,and enhancing cultivated land quality.Such efforts could provide important support for ensuring national food security and building an agricultural power.
