Dynamic change on the productivity of township health centers after China’s health care sys-tem reform：Based on the nonparametric Malmquist index in Guangzhou, Guangdong Prov-ince, 2009-2013 / 中国卫生政策研究

Objective:To explore the productivity of township health services in Guangzhou. Methods:We use a nonparametric Malmquist index approach to analyze total factor productivity change in Guangzhou’s township health service. The panel data was collected between 2009 and 2013. Results: The average growth rate of Guangzhou’s township health service was 18 . 7% from 2009 to 2013 . This growth was mainly due to improved technical progress but not technical efficiency. Pure technical efficiency and scale efficiency have not developed simultaneously. Conclusion:The change in the total factor productivity was positively affected by technical progress, not by strategic management and business decisions inside township health centers.
