Abstract:As a major agricultural province in western China, Gansu provides an important case for examining the relationship between agricultural modernization and farmers' income increase, which has significant practical implications for implementing the rural revitalization strategy, addressing the "Three Rural" issues, and promoting high-quality development of agriculture and rural areas in the province. Using data from the Gansu Rural Statistical Yearbook(2014-2024), the Grey Relational Model was first employed, followed by the application of a Vector Autoregression(VAR) model with data spanning 1996-2024, to investigate the dynamic interaction and inherent mechanisms between agricultural modernization and farmers' income growth in Gansu. The results demonstrate that agricultural modernization and farmers' income increase in Gansu exhibit a long-term, mutually reinforcing and inseparable relationship, which strengthens progressively with the advancement of agricultural modernization and the rise in farmers' income. Accordingly, to foster the synergistic development of agricultural modernization and increased agricultural production and farmers' income, this study recommends: strengthening agricultural scientific and technological innovation; promoting the transformation and application of research outcomes; giving full play to the leading role of new-type agricultural business entities; increasing governmental funding and strengthening supervision; broadening financing channels; and establishing a long-term dynamic monitoring platform.
