As proposed in a grant application submitted to the Council for Cultural Planning and Development, the aims of the project are twofold: to preserve folk customs through the medium of drama; and to borrow from tradition to create modern Chinese drama.
據優劇場向行政院文化建設委員會申請贊助的企劃書上所說，「溯」計畫具有雙重使命：一是藉著劇場形式來保存民俗，二是藉著回溯傳統，開創具有中國形式的現代劇場，且計畫在兩年之內依次在國家實驗劇場、全省各地露天野台、以及他們建於木柵的山上劇場演出。
