To ensure the energy of spinning reserve（SR） can be transmitted to the locational region successfully in the case of contingencies， the SR resources should be evenly distributed in the network. This paper develops an equilibrium model for the integrated energy-reserve electricity market with regional SR constraints， in which various constraints are considered simultaneously， including the transmission constraints， the system-wide SR requirement and the regional SR requirement. The regional SR requirement is met with both the locational generation resources and the unused transmission capacity of the corresponding tie line interface. Moreover， the energy price， reserve price and their coupling relationship are also discussed. As illustrated by numerical tests， the regional SR constraint may lead to increase of the energy price and reserve price within the reserve-shortage region， while the total profit may decrease accordingly. In the oligopolistic environment， the GenCo located in the reserve-shortage area could usually obtain more profit by increasing its energy output， which is different from the common way in which most GenCos could raise their profits by decreasing their energy outputs.
