The purpose of studying agriculture, rural areas and farmers is to solve the problems of increasing farmers' income, agricultural development and rural stability. In fact, this is the trinity of living area, occupation and subject identity, but the three have different emphases, so the above three issues must be considered comprehensively. As a big agricultural country, China's "three rural issues" are related to national quality, economic development, social stability, national prosperity and national rejuvenation.
To deal with the problem of agricultural development, we should not only focus on agriculture, rural areas and farmers themselves, but also take countermeasures from the outside of agriculture, rural areas and farmers, that is, their respective opposites. The significance of the theory of agricultural easy development lies in three aspects: unity of opposites and mutual transformation; agricultural industrialization management, agricultural innovation, functional diversification and humanism.
