The author comes to the conclusions that: the size of LSP is large, and its growth rate is high; the sex ratio of LSP is higher than the total population and working-age population, and comparatively speaking, its age structure is younger and cultural-educational quality is lower; the LFPR of total population goes steadily up; the characteristics of age-specific LFPR are similar to other countries; the LFPR of illiterate and semi-illiterate is lowest, and among the other population the higher the educational level, the lower the LFPR; the regional differences in the size, age-sex structure and cultural quality of LSP are obvious, and so is the LFPR.

首先对中国劳动力供给人口和劳动力参与率进行了研究，主要结论如下：劳动力供给人口的总量大、增长快；劳动力供给人口的性别比高于总人口和劳动年龄人口，其年龄构成比较年轻，文化素质也较低；总人口劳动力参与率稳步上升，1978—1994年，中国总人口劳动力参与率的回归模型为：Bt=40.1611(t-1977)〓(R〓=0.9150)；中国分年龄组劳动力参与率的特征与其他国家相类似，在15岁及以上人口中，文盲半文盲人口的劳动力参与率最低，其他文化程度人口则是文化层次越高，劳动力参与率越低。
