| 摘要:基于江苏省A市和B市城镇职工参保人异地就医住院的结算数据，采用描述性统计法及双重差分(DID)识别策略，估计了基本医疗保险异地就医“免备案”对异地住院人次、住院总费用及医保基金支出的实际影响。研究结果显示，取消备案会促使更多的本地参保人异地就医，且异地住院总费用显著增加(P<0.05)，对医保基金支出的影响并不显著(P>0.05)。对“异地”与“本地”患者实施差异化的支付水平有助于降低医保基金支出风险。 |

| Abstract:Based on the settlement data of urban employees in cities A and B in Jiangsu Province, this study evaluates the actual influence that the removal of record-filing process from the cross-region healthcare can have on the number of cross-region inpatients, the total cost of hospitalization and medical insurance funds by applying descriptive statistics and difference-in-difference model as identification strategy. The results showed that cross-region inpatient visits and medical expenditures increased after the policy intervention while the health insurance funds was not affected significantly, which implied that different payment rates should be set for local patients and cross-region patients to reduce the risk of medical insurance fund expenditure. |
