摘　　要：提出了新的农业信息化水平评价方法,以主成分分析法、综合指数法及波拉特法为基础,通过组合赋权,建立了农业信息化水平非线性加权综合评价模型.以酉阳县2006年至2017年的数据为例,综合评价其农业信息化水平,并对比分析了单一测算法与综合评价法的测算结果.经相关性分析表明酉阳县农业信息化水平与农业总产值显著相关,从而提出了促进酉阳县农业发展的指导性建议.This paper proposes a new evaluation method of agricultural informatization level. Based on Principal Component Analysis, Comprehensive Index Approach and Porat Approach, a nonlinear weighted comprehensive evaluation model of agricultural informatization level is established by combination weighting. Taking the data of Youyang county from 2006 to 2017 as an example, comprehensive evaluation of the agricultural informatization level, and the results of single calculation approach and comprehensive evaluation approach are compared and analyzed. The correlation analysis shows that the level of agricultural informatization in Youyang county is significantly correlated with the agricultural gross output value, and thus some guiding suggestions are put forward to promote agricultural development in Youyang county.
