本文主要論述共享經濟對區域整合的補充功能。共享經濟基於網際網路的演化、財富分配的新常態，以及超越現有規範的時效性，已經在貨品、資金、服務及人員移動方面，創造有別於傳統FTA 的整合效果。同時，共享經濟超越國家由上而下的區域主義架構，不僅可能衝擊主流商業模式的運作，同時也加速由下而上的區域化過程。共享經濟實為結合個體單位、社群互信，以及網絡科技並活用各類生產要素的另類區域整合模式。然而，共享經濟對監理法規、職種工時，以及交易模式概念的影響則尚待評估。

This could make an impact on main business models, while speed up the bottom-up regionalization process. The sharing economy is one kind of regional economic integration model that connects individuals and groups, community trust and internet technology and utilizes all types of production factors. However, issues facing the sharing economy include regulatory challenges, work structures and business transaction models.
