Objective: To assess the total factor productivity (TFP) of schistosomiasis control programs in Jiangsu Province, so as to provide insights into sustainable schistosomiasis control.
Methods: The data envelopment analysis-Malmquist index method was employed to analyze the human resources and financial investments in schistosomiasis control programs from health sectors in each schistosomiasis-endemic city of Jiangsu Province from 2005 to 2015, and assess the outputs of each schistosomiasis control project.
Results: The overall productive efficiency of schistosomiasis control programs in Jiangsu Province showed an increasing tendency, and the mean fluctuation of annual TFP was 2.3%. The comprehensive technical efficiency, including pure efficiency and scale efficiency, appeared a steady increase with minor fluctuations, and the mean fluctuation of annual comprehensive technical efficiency was 3.8%. The growth rate of technical progress fluctuated greatly from 2005 to 2011, and showed a steady increase from 2012 to 2015, which became a major contributor to the growth of TFP. A higher growth rate of TFP was seen in Huai ' an and Changzhou cities, which showed a greater comprehensive technical efficiency, and a large fluctuation was observed in the growth rate of technical progress in Yancheng, Nanjing, Huai ' an and Yangzhou cities.
Conclusions: There is a continuous improvement in the technical level of schistosomiasis control programs in Jiangsu Province, and technical application and supervision and management capacity also show a steady increase. In addition, the application of new techniques and new strategies contributes greatly to TFP growth. In the future, the investment into new techniques and new strategies should be increased to ensure the sustainable schistosomiasis control in Jiangsu Province.
［摘要］ 目的 评估江苏省卫生血防全要素生产率 (Total Factor Productivity, TFP), 为血吸虫病防治工作可持续性发展提供方向。方法 运用数据包络分析 (Malmquist 指数法) 对 2005–2015 年江苏省各血吸虫病流行市卫生血防人力和财政经费资源投入及各项血吸虫病防治工作量产出进行模型分析。结果 2005–2015 年江苏省血吸虫病防治工作各类生产效率总体呈上升趋势, 历年平均 TFP 变动率为 2.3%。综合技术效率在略有波动中稳步增长, 历年平均综合技术效率变动率为 3.8%。技术进步变动前期波动较大, 后期稳步增长, 成为 TFP 增长的主要来源。淮安、常州等市 TFP 变动率增长较快, 其综合技术效率较高; 盐城、南京、淮安、扬州等市技术进步变动率较高。结论 江苏省卫生血防技术水平不断提高, 技术运用和管理督导水平稳步上升。新技术新策略的应用对 TFP 贡献较大, 未来应加大对新技术新策略的投入, 保障江苏省血吸虫病防治工作可持续性发展。.
