Background: With increasing demands for medical treatment and healthcare, private hospitals have enjoyed rapid development, and the quality and satisfaction ratings of their medical services have gradually become hotspot issues. We aimed to investigate the influencing mechanisms of medical service quality, patient perceived value, patient satisfaction, and patient loyalty. Methods: On the basis of improved patient perceived value, service satisfaction, and loyalty scales, a questionnaire survey was conducted among 300 patients in 15 private hospitals in China. The action mechanisms of medical service quality, patient perceived value, patient satisfaction, and patient loyalty were verified via SPSS 22.0 and AMOS 20.0 statistical software. Results: The service quality of private hospitals was positively correlated with patient perceived value, patient satisfaction and patient loyalty. Patient perceived value was positively correlated with patient satisfaction. Patient perceived value, as well as patient satisfaction was positively correlated with patient loyalty. Patient perceived value and patient satisfaction play a mediating role between medical service quality and patient loyalty. Patient perceived value and patient satisfaction play a chain mediating role between medical service quality and patient loyalty. Conclusion: 1) Improving medical service quality is the main path to acquire patient loyalty for private hospitals. 2) When accepting high-quality medical services, patients will think that the cost paid is reasonable, and their satisfaction with private hospitals will consequently increase. 3) As patient satisfaction with private hospitals is elevated to a certain degree, they become increasingly willing to choose these hospitals again and recommend them to others.

Based on the problem of insufficient coordination of integrated machinery and technique configuration in the exploration of dry farming regions, a method of two-period comparative test was carried out in Shanxi Province, China. Zones of the effects of different treatments on straw coverage, soil moisture, emergence rate, seedling condition, yield, and benefit were monitored and analysed. The result was that the coverage before sowing decreased to below 55% after surface harrowing or rotary tillage in autumn by using dry farming technology in Northern China. The average number of emerging seedlings through surface tillage was larger than that without surface tillage by 1.7 plants/5 m; emergency rate was increased by 8.37%, and the increase in amplitude of grain yield reached 28% compared with that of traditional farming. Moreover, the input–output ratio reached 1:4.41. The experiments showed that the net income could reach RMB 1,251–1,401/hm2, and compared with traditional farming, operating cost was lowered by 23.1%–28.8%, and benefit was elevated by 48.8% with prominent cost saving and benefit increase. The study results will facilitate the improvement of water-saving and production-increasing technologies in Northern China and play a critical role in the development of agricultural cultivation and steady growth of agricultural output in this region.

This paper proposed three scholars PZB "service quality model" as the basic theory of SERVQUAL scale, with patients who come into contact with the medical care service quality interviews to determine the degree of importance of each index. Then on the joint use of the spss and liserl software, we get the data of the relevant results. Then analyze the results of the processing and integration of the amendment of the initial model, test hypotheses, ultimately get the quality evaluation model for the medical industry. Finally in accordance with results of the questionnaire survey data to make recommendations to improve medical institutions draw direction and future focus of the appraisal of the medical work.
