Comprehensive Evaluation System Research on Agricultural Modernization based on Principal Component of BP Network

摘要

Based on the current situation of agricultural modernization development (AMD) in 14 regions of Liaoning province during 2007 and 2010, a comprehensive evaluation system (PCABP) of AMD was established and comprehensive evaluation of Liaoning AMD was given by PCABP. Moreover, contrast the evaluation results of PCABP, PCA, and BP, getting the evaluation effect of PCA, BP and PCABP are increased respectively. Consequently, PCABP can improve the accuracy and stability significantly instead of the two separate evaluations, which providing a practical new way to evaluate agriculture modernization.
