摘要
作为现今信息流通的主要渠道,通信行业已经发展成为国家支柱产业,受到当代人们的广泛关注.本文基于目前最新《贵州统计年鉴》的数据,以2015年到2019年贵州省各市邮政、电信指标为研究对象,选取8个通信指标,通过稀疏因子分析法从8个通信水平评价指标提取出3个公因子,利用少数的公因子解释原始变量.用因子综合得分对2015年到2019年贵州省各城市通信水平进行排名,并对其进行综合评价.最后,结合实际情况对促进贵州省城市通信水平均衡发展提出建议.
As the main channel of information circulation today,the communication industry has developed into a national pillar industry,widely concerned by the contemporary people.Based on the latest data of Guizhou Statistical Yearbook,this paper takes the postal and telecommunications indexes of all cities in Guizhou province from 2015 to2019 as the research object,extracts 3 common factors from 8 communication level evaluation indexes through sparse factor analysis,and uses a few common factors to explain the original variables.The communication level of cities in Guizhou province from 2015 to 2019 is ranked and evaluated comprehensively by factor comprehensive score.Finally,some suggestions are proposed to promote the balanced development of urban communication level in Guizhou province.
