As part of its One Child Policy, China developed the one child certificate which offered numerous benefits to couples who had one child and promised to have no more. Using data from the Two-per-Thousand National Fertility Survey, this study describes the level of certificate acceptance in Hebei province from 1979 to 1988 and analyzes socioeconomic, cultural and early family formation factors affecting certificate acceptance as well as the role of certificate acceptance on transition to second parity. During the past decade, the level of initial certificate acceptance was 22.6 percent. This estimate is much lower than earlier published rates because it utilizes the concept of women at risk. Public resistance to the One Child Policy is evident in declining acceptance from 26.0 percent during the first five years of the policy to 11.3 percent during the 1984-1988 period. Women's response to the certificate has been influenced by the woman's status as reflected in education and occupation as well as cultural traditions, particularly son preference. The one child certificate, however, independently depresses subsequent fertility. This research indicates that efforts to understand fertility decline in China must simultaneously acknowledge the role of government family planning programs as well as socioeconomic and cultural factors.

To encourage compliance with this unique policy, the government developed the one child certificate which offered a variety of benefits to couples who had one child and promised to have no more (Feeney et al., 1989; Shen, 1984; Park and Han, 1988; Kaufman et al., 1989).Along with the incentives associated with the certificate, other family planning measures were introduced to restrict or negatively sanction noncompliance. The 1980 marriage law required every couple to practice birth control. Couples were required to secure permission to have a second child and such
