0科学预警早已拉响，为何公共健康政策却总在“最后一公里”徘徊？抗生素耐药性、活禽市场卫生风险……这些关乎每个人健康的议题，为何难以迅速转化为全国性的统一行动？问题的症结，或许不在科学证据的缺失，而在政策从纸面走向现实的复杂路径。
本期 MediHealth Podcast，我们对话杜克昆山大学环境政策学者 Van den Dool 教授。她将以中国公共卫生治理为切口，带你拆解“政策循环”与“多重流框架”的真实运作：一个健康议题如何跨越文化习惯、部门壁垒与政治时机，最终跻身国家议程？在科学、利益与制度的交织中，政策制定究竟是一场理性的规划，还是一次次危机驱动下的博弈？
如果你关心健康政策的落地逻辑，或想理解“同一健康”（One Health）理念在现实中的挑战与可能，本期节目将为你揭开政策幕后的真实图景。
Scientific warnings are clear, yet why do public health policies often stall before reachingimplementation? Issues like antimicrobial resistance and the health risks of live poultry markets are widely recognized—so why do coordinated national actions remain elusive? The bottleneck may not lie in a lack of evidence, but in the complex journey a problem takes to become policy.
In this episode of MediHealth Podcast, we sit down with Prof. Van den Dool, an environmental policy scholar at Duke Kunshan University. Drawing on China's public health governance, she unpacks the real-world mechanics of the "policy cycle" and the "Multiple Streams Framework". How does a health issue navigate cultural norms, bureaucratic silos, and political windows to finally reach the national agenda? Is policymaking a rational blueprint, or a series of negotiations shaped by crises, stakeholders, and timing?
If you are curious about the gap between scientific consensus and policy action, or want to understand the real challenges of implementing a “One Health” approach, this episode offers a grounded, behind-the-scenes look at how health policies are truly made.
