农产品物流损耗原因分析

利用因子分析对我国31个省和直辖市的样本的农产品物流损耗原因进行综合分析。分析农产品物流环节中常见损耗情况及其原因，建立农产品物流损耗原因分析指标体系，利用因子分析对农产品物流损耗原因进行分析重组；再利用新重组的因子代替原先较多的变量指标对我国31个省和直辖市样本进行Q型聚类分析，对各省和直辖市的农产品物流损耗原因进行综合分析评价并提出优化建议。该方法可使复杂且难以量化的农产品物流损耗问题得到客观、可信的原因分析。

The method of factor analysis and cluster analysis is to conduct a comprehensive analysis of agricultural products logistics loss according to samples of 31 Chinese provinces and municipalities. Analyzing the situation and the reasons for loss of common agricultural products logistics, agricultural products logistics loss analysis indexes systemwas established. Factor analysis was used to restructure agricultural products logistics loss factors evaluation because information overlaps lying in multi-indexes. Q type cluster analysiswas used to classify these provinces and municipalitiesinto several categories, according to new recombinant indexes obtained from factor analysis, and made recommendations from the result. The method can simplify agricultural products logistics loss problems and lead to objective, credible conclusion.
