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.
