Based on the importance of the internal information system of public hospitals in hospital work, this paper analyzes the security risks and operational risks existing in the use of the current hospital information system, explores the importance and development measures of information system audit, and improves the operation quality and service efficiency of the internal information system of hospitals.展开更多

Because processing imports are inputs for exports, the link between such imports and China＇s exchange rates are ambiguous. We estimate export functions that include China＇s RMB real effective exchauge rates （REER） along with bilateral real exchange rates （B RER） using Johausen ＇s cointegration method aud find that the RMB REER significantly affects Japanese and Korean exports to China, even more so than BRER in most cases examined. These two exchange rates appear in the export equations with opposite signs. Subsequently, we use the estimated model to illustrate the importance of accounting for a concurrent change in B RER when analyzing the effects of a hypothetical RMB revaluation on China＇s trade balances despite the apparently weak imports-B RER linkage.展开更多
