Abstract: Surgery appointment platforms can help alleviate the problem of “difficulty in accessing medical care”. However, the development of this model has long been constrained by relatively low medical quality and insufficient traffic conversion. How platforms and primary-level hospitals can enhance medical quality through online-offline collaboration is therefore key to overcoming these challenges. From the perspective of medical quality, this paper constructs a complete-information dynamic game model between platforms and primary-level hospitals to examine their collaborative strategies. The findings show that the efforts made by both parties to improve medical quality are related to the initial medical quality of primary-level hospitals. When the platforms collaborate with primary-level hospitals whose overall initial medical quality is relatively low, a higher initial medical quality leads to a corresponding increase—either monotonic or wave-like—in the equilibrium improvement of medical quality, until a maximum is reached. Due to the free-rider effect, when platforms collaborate with primary-level hospitals whose overall initial medical quality is relatively high, a higher the initial medical quality instead results in a smaller equilibrium improvement in medical quality. When platforms collaborate with primary-level hospitals with a moderate level of initial medical quality, a moderate level of difficulty in improving medical quality is most conducive to overall quality enhancement.

摘要： 手术类医疗平台有助于缓解“就医难”问题。然而，该模式的发展长期受医疗质量偏低、流量转化不足的制约而踟蹰不前，平台与基层医院如何通过线上线下合作提升医疗质量，是突破这一困境的关键。为此，本文基于医疗质量视角，构建平台与基层医院的完全信息动态博弈模型，研究双方的合作策略问题。研究发现：双方为提升医疗质量所付出的努力，与基层医院的初始医疗质量密切相关。当平台与初始医疗质量总体较低的基层医院合作时，基层医院的初始医疗质量越高，医疗质量的均衡提升程度也会相应提高或呈波浪式增长，直至达到最大值；由于搭便车效应的存在，当平台与初始医疗质量总体较高的基层医院合作时，基层医院的初始医疗质量越高，医疗质量的均衡提升程度反而越小；当平台与初始医疗质量中等的基层医院合作时，若基层医院提升医疗质量的难度处于中等水平，则最有利于医疗质量的提升。
