迁移效率指数、偏好指数和差别指数
迁移效率指数、偏好指数和差别指数迁移效率指数是用于测定两地间人口迁移效率的指标。它是净迁移对总迁移之比。计算公式为:EIM一摇寿纂拼又‘。。上式中,}人么夕一材方}为i、]两地净迁移人数;从少+材户为i、]两地总迁移人数;El入了为迁移效率指数。 EIM的取值范围为。至100,如某一地区的值越大,反映迁移的的影响也越大。如果计算i地区与其他一切地区之间的人口迁移效率指数EIM厂,则: }艺材。一芝Mj、}EIM汀艺。+乏M,(j笋i) 迁移偏好指数是从一个地区向另一地区的实际迁移人数与期望迁移人数之比。计算公式为:____M.___材尸2行一:一二子一一不石一二,么M“ 了厂‘.厂‘、八 }二不十二六二1 、厂厂7上式中,M“为从i地迁到j地的实际迁移量;艺材。为总的人口迁移量;尸为总人口;M尸I,j为迁移偏好指数。通过计算迁移偏好指数,可以反映各地区的相对引力。 迁移差别指数是反映具有某种特征的迁移人口与非迁移人口区别的指数。例如,专业技术人员的人数所占比重,各种文化程度人数所占比重等,以便研究人才流失和其他间题。计算公式为:M‘从IMD、一翌不丝xl。。 .义V‘ N上式中,M为迁移人数;M,为具有i特征的迁移人数;N为非迁移人数;N‘为具有i特征的非迁移人数;了八了D、为迁移差别指数。
