摘要
以中国已婚育龄个体避孕措施选择的定量及定性相结合的分析为研究起点,揭示育龄个体避孕诉求与国家计划生育意志之间存在冲突的社会事实,即个体偏好短效自控型避孕措施,而国家着力推行长效医控型避孕措施。当个体诉求与国家意志相遇,在互动中发生有限理性条件下的演进博弈,并形成演进稳定策略,出现唯一非合作演进均衡。
Using the large scale data from the national conventional statistics and nationally representative sample surveys, the current study aimed at assessing the social fact that there was a conflict between the birth control policy and the individual childbearing desire. The policy encouraged individuals to pursue long - acting contraceptives use, however, the individuals preferred to choose short - acting methods. There existed a non - cooperative Evolutionarily Stable Strategy（ESS） in the evolutionary game in which the central government was satisfied with the long - acting methods prevalence and the individuals were satisfied with their choices. The study demonstrates that how individual desire can bend the iron bars of the formal institutions.
