Early life and career in academia
Sun Zhigang was born in May 1954 in Xingyang, Henan province. He joined the work force in February 1971 during the Cultural Revolution as a sent-down youth in Xingyang. In 1973, he entered Wuhan Institute of Metallurgy (now incorporated into Wuhan University of Science and Technology) as a "Worker-Peasant-Soldier student". He joined the Communist Party of China in September 1976. 

After graduating from college, Sun stayed at his alma mater as an instructor. He entered the Shanghai University of Finance and Economics to pursue graduate studies in economics, then he became, for a brief period, a research fellow at Zhongnan University of Economics and Law. In April 1985, he quit academia to pursue a career in politics, entering the Wuhan municipal government.

Political career
In Wuhan, the provincial capital, Sun became the deputy head of the city's economics commission, and also in charge of economic restructuring. He became the district deputy party chief, then governor of Hanyang District. In March 1993 he was named vice mayor of Wuhan, then transferred to serve as the mayor of Yichang in August 1996, and promoted to party chief in March 1999. He became a member of the provincial Party Standing Committee in June 2002, and the secretary-general of the Party Committee, becoming chief of staff under then-party chief Yu Zhengsheng.

Beginning in September 2006, Sun began serving as executive vice governor of Anhui province, and a member of the party ruling council there. After a comprehensive set of health care reforms were put into effect by the central government, Sun spearheaded implementation of the reforms in Anhui province, pioneering a government drug purchase program which was circulated at the national level and dubbed the "Anhui model." He was then tasked with implementing the Anhui model nationwide, taking on the role of deputy director of the National Development and Reform Commission in March 2010, and then in December 2010, the chief of the Office of Health Care Reform. In a government reshuffle in March 2013, Sun was named deputy director of the National Health and Family Planning Commission.
