The average growth rate of total expenditures and expenditure categories before and after the reform. Note: a Total inpatient expenditure. b Drug expenditure. c Diagnostic testing expenditure. d Physician services and therapeutic services expenditure. The formula of the average growth rate (AGR) before the reform (2007–2012) was ${\mathit{AGR}}_{2007-2012}=\left(\sqrt[5]{\frac{\mathit{\text{Expenditure}}2012}{\mathit{\text{Expenditure}}2007}}-1\right)\times 100\%$. The formula of AGR after the reform (2013–2016) was ${\mathit{AGR}}_{2013-2016}=\left(\sqrt[3]{\frac{\mathit{\text{Expenditure}}2016}{\mathit{\text{Expenditure}}2013}}-1\right)\times 100\%$
