中文摘要：

城乡统筹背景下土地利用政策的关键是如何处理城市用地扩张与保护耕地之间的矛盾。通过分析城乡土地利用中的三类外部性和现有城乡挂钩试验的基础上,提出在大区域和都市区内进行土地发展权转移,使市场机制和土地利用规划相结合的策略。在大区域层次上,主要是进行地区间城乡挂钩指标或有关用地指标的交易;在都市区内,则是以农民集体组织为单位进行土地发展权转移的交易。

英文摘要：

Against the background of current public policy of urban-rural coordinated development,a key land policy issue is how to deal with the conflict between urban expansion and farmland protection.By analyzing three major types of externality in urban-rural land use and the current trial of ＂urban-rural hook-up＂ land use policy,we propose establishing markets for transfer of development rights（TDR）at both regional level and metropolitan level.In this way,market mechanism and land use planning are integrated.In the regional market the quotas for ＂urban-rural hook-up＂ trial or some land use quotas are traded;at the metropolitan level,the market participants are peasant collectives who trade the development rights.Some technical details and policy implications are also discussed in the paper.
