研究表明，我國目標出口退稅機制需要從五個方面進行構建：即增值稅制度改革、退稅率設置、退稅管理辦法統一、退稅財政分擔優化和退稅管理的強化，最終方可達到總體退稅成本最低和退稅收益的最大化。更具體地說，一是改革現行增值稅制度，將我國增值稅制度由生產型逐步轉為消費型，並強化征稅管理，為退稅機制的優化奠定基礎；二是在綜合考慮國內國際實際情況的前提條件下，選擇適宜我國的「中性與非中性」相結合的退稅率，並建立一套具有相對穩定性和適時靈活性的彈性退稅率機制；三是伴隨著外貿體制改革的進一步深化和退稅管理能力的逐步提高，將現行兩種出口退稅管理辦法逐步過渡到以「免、抵、退」為主的單一管理辦法；四是改革現行增值稅共享辦法，建立「先退稅后共享」的新型退稅負擔機制；五是建立一套針對出口企業和稅務機關的激勵約束機制，有效強化出口退稅的管理。
