Regional electric power carbon emission factor calculation method and system

The invention discloses a regional power carbon emission factor calculation method and system. The method comprises the following steps: acquiring time-sharing electricity consumption and generating capacity of a time-sharing unit in a current area; according to the time-sharing unit generating capacity, time-sharing and type-sharing generating capacity is determined, and according to the time-sharing and type-sharing generating capacity, time-sharing total generating capacity is determined; determining the proportion of each time-sharing power generation type according to the time-sharing total power generation amount and the time-sharing and type-sharing power generation amount; determining a national average power carbon factor and power carbon factors of different power generation types; according to the time-sharing and type-sharing power generation amount, the power-carbon factors of different power generation types, the time-sharing power consumption, the time-sharing total power generation amount, the
