中文摘要：

新型城镇化已经成为我国的国家发展战略,但我国目前在城镇土地的再整治上面临着不少困难,制约了城镇化目标的实现。以上海市五角场镇的土地置换实践探索为研究样本,对现行的土地出让制度及依赖土地财政为主的＂经营城市＂的思路进行分析,探寻实施土地直接置换、推动新型城镇化发展的主要障碍及其原因。并提出基于土地直接置换的＂自主置换整治型＂与＂政府主导整治型＂两种市地整治类型,进而从现有政策法规与国内外实践分析了这种模式实施的可行性,并从政策保障、机构建设、权属调整、资金筹措与配套措施5个方面提出土地直接置换的市地整治模式的规范性建议。

英文摘要：

New urbanization has been a national development strategy of China and it is now facing many difficulties. The urban land readjustment is one of the effective tools for new urbanization. From the practice of land direct replacement in Wujiaochang Town of Shanghai, the research concluded that the current land transfer system and the policy frame of managing city mainly depended on land finance and have become the main obstacle to the land exchange and urban land replacement. Based on the thinking of land direct replacement, the ＂independent replacement regulation model＂ and ＂government---dominated regulation model＂ were built for the urban land replacement with the existing policies, regulations and practice. The feasibility of implementing urban land replacement was analyzed and regulatory suggestions were put forward from the perspectives of policy support, institution building, landownership adjustment, fund raising and supporting measures.
