Abstract: In order to compare the importance of various influencing factors in the promotion process of agricultural APP, farmers in Yantai City, Tai’an City, and Weihai City, Shandong Province were selected as the research objects. Typical correlation analysis methods were used to analyze subjective factors and objective factors on farmers’ use of agricultural APP. The results indicated that the degree of understanding of the software among subjective factors was the main factor determining whether to use agricultural APP, while whether traditional information channels met information needs was a secondary factor. When traditional information channels could not meet farmers’ information needs, it was beneficial for the promotion of the software;the average monthly frequency of obtaining technical guidance and the age of farmers were the main and secondary factors in objective factors, respectively. In summary, when promoting agricultural APP, the focus should be on farmers over 40 years old, and on areas where traditional information channels had developed well but couldn’t fully meet farmers’ needs for agricultural information. Emphasis should be placed on cultivating farmers’ software usage abilities.

Key words: agricultural APP, objective factors, subjective factors, canonical correlation analysis
