Abstract
In this paper, we analyze the influence of cooperation between medical and nursing care on the hospital technical efficiency, to verify the validity of H&W CO−OP JAPAN ongoing managerial strategy. The procedure adopted here is as follows. Firstly, the order on technical efficiency among 56 H&W CO−OP JAPAN hospitals is examined through DEA−bootstrap approach. Then we detect the effect of running nursing care facilities on hospital technical efficiency by applying Wilcoxon rank sum test to the ranking of two groups of individual hospital, one runs more than 5 facilities and the other runs less than 1, measured above. As a result, statistically significant positive correlation is found out.
