China is at the transition stage of optimizing its fertility policy. Based on the policy style interpretation framework, this article focuses on the Chinese style of fertility policy, and can analyze the recursive picture from crisis design to rational design, then to gradual design, and gradually realize the social design. This corresponds to four types of executive logic: authoritative, expert-guided, coordinated, and multi-cooperative. The Chinese style of the reproductive policy can be summarized as “state capacity leads to the social order”, which embodies on the dual evolution of the design and implementation of the “the governance of China”. Facing the long-term, complex and severe super-social project of solving China's population problem, the fertility policy style is based on the socialist system with Chinese characteristics, and contains China's unique governing characteristics and governance elements, namely "conforms to China's national conditions of good governance" design and implementation of innovation "concentrate resources to accomplish large undertakings". Based on the dual evolution of China's fertility policy in the design and implementation, it is possible to objectively and comprehensively understand the changes in the mission of fertility policy from social management that restricts fertility to public services that encourage fertility, and to better integrate all forces so that the top-level design and implementation process of future fertility policies can take into account the needs of the country and the direction of public opinion. 

中国正处于进一步优化生育政策的窗口期,亟待温故知新。基于政策风格解释框架,本文聚焦既往生育政策的中国风格,可解析出从危机设计到理性设计、再到渐进设计、逐渐实现社会设计的递归性图景;与此对应的是四种执行逻辑:科层权威型、专家引导型、统筹协调型和多元合作型。优化生育政策的逻辑变迁可概括为 “国家能力引领社会秩序”,集中体现 “中国之治”在设计与执行上的双元演进。毋庸置疑,优化生育政策这一长期性、复杂性与严峻性的超级社会工程的逻辑变迁,蕴含着中国独特的执政特色与治理元素,即 “符合中国国情”的善治设计与 “集中力量办大事”的执行创新。以优化生育政策在设计与执行上的双元演进为基础,才能客观和全面理解优化生育政策从生育限制的社会管理到生育支持的公共服务之使命的善治变迁,亦能更好地整合多元力量使中国特色生育支持政策体系的顶层设计和执行过程都能兼顾国祚所需与民意所向。
