In economy, the Old Empire rigidly controlled overseas trade of the colonies, and passed the Navigation Act. This system had been reasonable, but it could not be accommodated to the problem after the Seven Years War. The contradiction between America and Great Britain led to the collapse of the Old Empire.

旧帝国的特征体现在经济方面则是英国对殖民地的对外贸易进行严格限制，英国通过《航海条例》控制了殖民地的生产和贸易，这个体制曾经具有其时代合理性，但是&七年战争&之后，英帝国的形势发生了很大的变化，重商主义殖民政策已经无法解决帝国所面临的难题，英国同美洲殖民地的矛盾越来越大，最终导致了旧帝国的崩溃。
