Considering the increase of financial deficits, it becomes more important to select lower cost and more effective strategy in green space acquisition and enhancement. There exist many methods for the green space acquisition and enhancement, such as development of city parks, conservation of woods, and application of greening district. Each method has the different public cost performance for the fulfillment. Therefore, it is necessary for the policy-making to compare the cost performance in the different methods. This paper tries to show the models of the cost performance and to evaluate the public cost and benefit of methods. For achieving this purpose, this paper firstly surveys the government green space policy from the point of view of the cost, secondly shows the model of the public and private cost of each method, and explain the benefit by comparing the effectiveness and longevity of green space acquired by each method, and thirdly evaluate the ongoing methods of government and local authorities by this model, finally discuss about the directions of future green space policy.
