英文文献摘要：
This study analyzes difference in efficiency among the U.S. rural hospitals using a two-stage, semi-parametric approach. Data Envelopment Analysis is used in the first stage to calculate cost, technical and allocative efficiencies of Critical Access Hospitals (CAH) and non-CAH rural hospitals. Following Simar and Wilson (2007), bootstrapped truncated regressions are used in the second stage to infer on relationship between the cost, technical and allocative inefficiencies of hospitals and some environmental variables. The estimated results show that CAHs are less cost, technical and allocative efficient than non-CAH rural hospitals. The results also show that Medicare cost-based reimbursement for CAHs has a negative effect on the efficiency of these hospitals while Medicare prospective payment system for non-CAH rural hospitals has a positive effect on hospital efficiency.

本研究采用两阶段半参数方法分析了美国农村医院的效率差异。第一阶段使用数据包络分析计算关键准入医院(CAH)和非农村医院的成本、技术和配置效率。继Simar和Wilson(2007)之后，第二阶段使用bootstrap truncated regression来推断医院的成本、技术和配置效率低下与一些环境变量之间的关系。估计结果表明，CAHs的成本、技术效率和配置效率均低于非cah农村医院。结果还表明，农村非cah医院的医保费用报销对医院效率有负向影响，而农村非cah医院的医保预期支付制度对医院效率有正向影响。
