As emphasis has been placed on using the incentive-based mechanism by the central government, rapid progress on PES research and practice has been achieved. However PES still faces many difficulties. A key issue is the lack of a fully-fledged theory and method to clearly define the design scope, accounting and feasibility of PES criteria. An improved watershed criteria model was developed in light of research on PES practices in China, investigations on the water source area for the Middle Route Project of South-to-North Water Diversion and ecosystem services outflows theory. The basic principle of assessment is the direct and opportunity cost for ecological conservation and environmental protection in the water source area deduct nationally-financed PES and internal effect. Then the scope and the criteria methods were determined, and internal effect was put forward to define benefits brought from water source area. Finally, Shiyan City, which is the main water source area for the Project of Water Diversion, was analyzed by this model and its payment was calculated. The results showed that： （1） during 2003–2050, the total direct cost and opportunity cost would reach up to 262.70 billion and 256.33 billion Chinese Yuan （CNY, 2000 constant prices）, i.e., 50.61% and 49.38% of total cost, respectively; （2） Shiyan City would gain 0.23, 0.06 and 0.03 CNY/m3 in 2014–2020, 2021–2030, and 2031–2050, respectively.展开更多

Since April 2004, the system has been gradually extended to general hospitals that satisfy certain prerequisites. In this paper, the new inclusive payment system is analyzed. Data pertaining to 1,225 patients, who were hospital-ized for cataract diseases and underwent lens operations from July 2004 to September 2005, are used. The lengths of hospital stay and medical payments among hospitals are com-pared. Even after eliminating the influence of patient characteristics, there are large differ-ences among hospitals in average lengths of hospital stay and DPC-based inclusive pay-ments. The highest average inclusive payment is 3.5 times as high as the lowest payment. On the other hand, there are relatively small differ-ences in non-inclusive payments based on the conventional fee-for-service system—the larg-est deviation from the average of all hospitals is approximately 10%. Thus, although payments based on the DPC account for only one-third of the total medical payments for this disease, the major differences in medical payments among hospitals are caused by differences in their DPC-based inclusive payments. The results of the study strongly suggest that revisions of the payment system in Japan are necessary for the efficient use of medical resources in the future.展开更多

Indicators like means,increase（decrease） percentages were used to descriptively analyze the average hospitalization expense of each time（AHEET） and its trends of breast cancer patients with different medical insurance coverages treated in medical institutions of different types and grades.Results：In 2011–2015,the AHEET borne by breast cancer patients in China had been constantly increasing.Specifically,the self-pay inpatients had the largest increase,inpatients covered by Urban Employee Basic Medical Insurance（UEBMI）and Urban Resident Basic Medical Insurance（URBMI）were the next,and those covered by New Rural Cooperative Medical System（NRCMS）had the least increase.Breast cancer inpatient treated in public hospitals had quite greater increase and higher expenditure level than those in private hospitals.The AHEET borne by the inpatients in Grade 3 hospitals had greater increase and higher cost than those in Grade 2 hospitals.Conclusions：The inpatient payments of breast cancer patients will be wisely controlled by reducing the number of self-pay inpatients,taking advantage of restriction mechanism of the medical insurances,and promoting healthy competition between private hospitals and public hospitals.The economic burden imposed on the society by breast cancer can be relieved through further control of inpatient payments of UEBMI-and URBMI-covered breast cancer patients and of Grade 3 hospitals.展开更多

In addition, virtualization technology is applied to isolate TOS from normal OS. Users complete ordinary affairs in normal OS and security-sensitive affairs in TOS. TMPE can offer users a highly protected environment for mobile payment. Moreover, TMPE has good compatibility in different hardware architectures of mobile platforms.
