离婚率是衡量社会稳定、家庭幸福度的重要指标。高离婚率往往带来家庭关系的不和谐以及社会的不稳定性。随着国内对离婚审查期的政策调整，离婚程序简易化、离婚低成本化。这也带来了冲动离婚、假离婚等社会现象，由此引起社会热议。离婚政策关系失睦家庭夫妻双方的选择，体现着人民群众的利益诉求。如何科学制定离婚政策，有效化解社会问题，回应社会关切成为重要的课题。离婚冷静期政策的制定契合了社会发展所需，分析该政策制定过程，对于后续政策优化有着重要的借鉴性价值。

研究运用多源流理论从问题源流、政策源流、政治源流等出发对中国离婚冷静期政策进行深入分析，把握政策制定过程中各源流的作用，进一步了解政策议程“暗箱”，为政策优化与完善提供相应的建议。研究主要内容包括三个方面：其一，从历史性维度梳理中国离婚政策变迁，并对离婚数据进行解读，明晰当前国内离婚状况；其二，运用多源流理论对离婚冷静期政策进行有效梳理，把握各种要素具体作用以及三源流的耦合所带来的政策之窗开启情况；其三，多源流理论下优化中国离婚冷静期政策的路径。综合这三个方面的研究内容认为，中国离婚冷静期政策的制定是契合人民群众根本利益的政策内容。离婚冷静期政策制定中焦点事件发挥了催化剂的作用，催生了社会问题的讨论，也引起了更多的社会关注，同时各类问题的出现进一步促使人大代表、专家学者对问题的讨论。在政府理念、国民情绪的作用下，社会问题获得政府及领导人的重视，最终三源流实现耦合，创造了政策之窗。多源流理论对于理解中国离婚冷静期政策具有重要意义，同时考虑到离婚冷静期政策也应随着时代变化、特殊情境而有所相应调整，借鉴该理论，在未来的政策优化中需要锁定问题源流，扩大信息来源；厘清政策源流，选择恰当方式；借力政治源流，优化舆论环境；把握政策之窗，优化政策内容。

Divorce rate is an important indicator of social stability and family happiness. The high divorce rate often brings about the disharmony of family relations and the instability of society. With the adjustment of the domestic policy on the divorce review period, the divorce procedure is simplified and the divorce is low-cost. This has also led to impulsive divorce, fake divorce and other social phenomena, which has caused heated social debate. The divorce policy reflects the interests of the people. How to formulate divorce policy scientifically, effectively solve social problems and respond to social concerns has become an important issue. The formulation of divorce cooling-off period policy meets the needs of social development, and the analysis of the formulation process of this policy has important reference value for the subsequent policy optimization.

This study applies the theory of multiple sources to make an in-depth analysis of China's divorce cooling-off period policies from the perspectives of problem sources, policy sources and political sources, grasp the role of various sources in the policymaking process, further understand the "dark box" of policy agenda, and provide corresponding suggestions for policy optimization and improvement. The main contents of the study include three aspects: first, the changes of China's divorce policy are sorted out from the historical dimension, and the divorce data are interpreted to clarify the current domestic divorce situation; Second, the multi-source theory is used to effectively sort out the divorce cooling-off period policy, grasp the specific role of various factors and the opening of the policy window brought by the coupling of the three sources. Third, the path to optimize China's divorce cooling-off period policy under the theory of multiple sources. Based on these three aspects, it is concluded that the formulation of divorce cooling-off period policy in China is a policy content that conforms to the fundamental interests of the people. The focal events in the formulation of the divorce cooling-off period policy played a catalyst role, which stimulated the discussion of social issues and attracted more social attention. Meanwhile, the emergence of various problems further promoted the discussion of issues among deputies to the National People's Congress, experts and scholars. Under the influence of government philosophy and national sentiment, social issues have been paid more attention by the government and its leaders. Finally, the coupling of the three sources has created a policy window. The theory of multi-source flow is of great significance for understanding China's divorce cooling-off period policy. At the same time, considering that the policy of divorce cooling-off period should be adjusted accordingly with the change of times and special circumstances, it is necessary to lock the source of problems and expand the source of information in the future policy optimization based on this theory. Clarify the source of policy and choose the appropriate way; Leverage political sources to optimize public opinion environment; Grasp the policy window, optimize the policy content.
