从可持续生计视角,构建县域多维贫困测度指标体系,对四川藏区不同县域多维贫困状况展开跨时区测度与比较。研究发现：进入21世纪以来,四川藏区农牧业、社会事业得到较大发展,藏区社会成员收入得到较大提高。随着时间推移,四川藏区各县域多维贫困程度在波动中不断减轻。在扶贫开发的相对初期,各县域多维贫困趋同性大于异质性（“均贫”）;在扶贫开发的相对中期,其异质性大于趋同性（“贫富不均”）;在扶贫开发的相对后期,其趋同性大于异质性（“均富”）。目前四川藏区各县域多维贫困以轻度和中度为主。金融资本、社会资本和人力资本对四川藏区各县域多维贫困贡献度较大,自然资本贡献度呈上升趋势。

At present, the multidimensional poverty in these counties is at mild and moderate degrees.
