China’s coastal areas are the regions with the most prominent contradiction between supply and demand of land resources, where the oversize planning and expansion of economic zones have exacerbated the urban land issues. In this paper, economic zones were divided into three types according to the location relations between sixteen coastal economic zones and cities, which are away from city, at the edge of a city and inside a city. The spatial characteristics of the expansion of these three types of economic zones and the economic characteristics of the economic zones were studied. The research indicated that the expansion of the economic zones was related to the stage of economic growth and the peaks appeared at the early stage and the “second-time undertaking” stage. After 25 years of development, the largest expansion of the economic zone was less than 60 km2 in the current environment of economic development and land policy. In addition, the directions and forms of the expansion of different types are different. The economic zones away from cities expanded in multiple directions and along the traffic lines. The economic zones inside a city expanded inward or expanded outward in a narrow fan-shaped area, while the economic zones at the edge of a city could expand in areas from a wide fan-shaped to a semicircle. The expansion of the zones far away from city needs more investment, however, there are more room for economic development and higher economic output. Therefore, the scale and speed of expansion of the economic zones need to be planned properly in light of the local capital strength, the location and stage of the development of the zones.
