主成分分析与熵值法综合评价云南省乡村振兴发展水平

Comprehensive Evaluation of the Development of Rural Revitalization in Yunnan Province by the Principal Component Analysis and Entropy Value Method

实施乡村振兴战略有利于解决我国长久以来的“三农”问题。本文以乡村振兴战略五大基本内容为一级指标,以粮食总产量等20项具体内容为二级指标构建评价体系,并分别采用主成分分析和熵值法测算云南省乡村振兴综合发展水平,进一步采用加权秩和比法测算出Level数值并进行归档。结果显示,两种评价方法下的RSR拟合值存在轻微差异,但最终的分档等级是一致的。具体表现为:2011年云南省乡村发展水平存在小幅回落,但整体呈现稳步上升态势;从2019年起,乡村振兴整体水平开始大幅上升,表明我国2017年提出的乡村振兴战略对云南省农村地区的发展产生了积极的推动力。

The implementation of a rural revitalization strategy is conducive to solving China's long-standing problems of agriculture,rural areas and farmers.In this paper,the evaluation system is constructed with the five basic contents of the nural revitalization strategy as the first-level indicators,and twenty specific contents such as the total grain output as the second-level indicators,and the level of comprehensive development of rural revitalization in Yunnan Province is measured by the principal component analysis and entropy value method,respectively,and the level is further measured by the weighted rank-sum-ratio(RSR)method,and is filed.The results show that there are slight diferences in the fitted values of RSR under the two evaluation methods,but the fnal graded level is consistent.Specifically,there is a small drop in the level of rural development in Yunnan Province in 2011,but the overall trend of steady increase;from 2019,the overall level of nural revitalization began to rise sharply,indicating that China's strategy of nural revitalization put forward in 2017 has produced a positive impetus to the development of nural areas in Yunnan Province.
