Mianzhu County is among Sichuan Province's more successful counties in family planning. Following Marx's theory of the 2-fold character of production, Mianzhu County in 1980 simultaneously transferred both agricultural production and family planning work to the work crew by implementing "double transfer of responsiblity," thereby mobilizing cadres and people to understand both time material production and human reproduction, i.e., "grains, money and people." Last year when the agricultural production responsiblity system was established and production was contracted to the work crew, it was decided to transfer both production and birth quotas to the work crew through a system of monetary rewards for sucessful family planning and fines for unplanned births. Results from the double responsiblity system show that: the grain production kept up with 1979 levels; the rate of natural population increase dropped from 1979's 4.1/1000 to 1.57/1000 in 1980; the single-child family rate was 94%; the multiple child family rate was .3/1000; the rate of applications for the Single Child Certificate was 97.5%. At first the work crew felt that their repsonsibility was production and that family planning was a personal matter. But after extensive propaganda efforts to teach Marxist population theory and to stress the need to control population, the work crew realized that family planning is everyone's concern just as production is everyone's concern. With the "double transfer or responsiblity," the working relationship among communes, production brigades, production teams, and work crews improved, and advocacy of the single-child family was strengthened and expanded.
