有关自由经济区的静态研究众多，但对其演化规律的归纳与总结较少。在相关研究的基础上，通过对自由经济区的类型划分以及发展演化阶段的回顾，从目标、区位、产业、政策、管理和空间结构等因素入手，归纳和总结出了世界自由经济区演化规律，并建立了自由经济区统一的演化模式，世界自由经济区正由贸易型向综合型类型，由外资和区域优惠导向向区域和产业优惠导向，由特殊经济区向特殊行政区域，由国内向跨边界区域，由劳动密集向资本和技术密集转化，由临近港口向更为灵活的区位和更大的空间的方向发展。根据世界自由经济区演化模式和天津滨海新区的现状与问题，天津滨海新区应选择开放型与封闭型、综合与专业功能型相结合、复合型梯度自由经济区发展模式；随着经济发展和制度创新，中期可以采用封闭型、综合复合型自由贸易区发展模式；远期有望成为类似于香港与澳门的特别经济和行政区。

There are numerous theoretical and empirical studies on FEZs, but only little consideration has been given to when, why, and how FEZs evolve under diverse economic, political, social-cultural and spatial conditions on different scales. This paper tries to put forward the structural and spatial evolutionary model of FEZs by classifying world free economic zone (FEZ), and analyzes its development of objectives, preferential policy, governance structure, industrial sectors and location of FEZs based on the international economic and political development. FEZs develop towards ① more comprehensive and macro objectives, ② more industry-oriented and multi preferential policies, ③ more cross-national and combinational zones with administrative feature, ④ more technology-intensive and multi-industries, ⑤ more flexible location and larger spatial dimension, ⑥ more rapid evolution and typologies, and ⑦ more economic integration. Based on the evolution of world FEZ, the overall planing and current situation, Tianjin Binhai New Area (TBNA) should choose the complex, gradient model of FEZ, namely a combination between the open-close customs surpervison as well as the comprehensive function and specialization. Following the road to economic development and reform, TBNA could select a close, comprehensive and complex model of FEZ in the middle stage and the Hong Kong or Macao model in the long-term goal.
