A Party Committee Secretary is the leader of the Chinese Communist Party (CCP) organization in a province, city, village, or other administrative unit. In most cases, it is the de facto highest political office of its area of jurisdiction. The term can also be used for the leadership position of CCP organizations in state-owned enterprises, private companies, foreign-owned companies, universities, research institutes, hospitals, as well as other institutions of the state.
Post-Cultural Revolution, the CCP is responsible for the formulation of policies and the government is responsible for its day-to-day execution. At every level of jurisdiction, a government leader serves alongside the party secretary. For example, in the case of a province, the provincial Party Secretary is the de facto highest office, but the government is headed by a government leader called a "Governor" (simplified Chinese: 省长; traditional Chinese: 省長; pinyin: shěng zhǎng). The Governor is usually the second-highest-ranking official in the party's Provincial Committee, and holds the concurrent title of "Deputy Party Committee Secretary" (simplified Chinese: 省委副书记; traditional Chinese: 省委副書記; pinyin: shěng wěi fù shū jì). A similar comparison can be made for municipal Party Secretaries and Mayors in city-level, or even for the general secretary of CCP and the Premier of State Council in state-level.
