Abstract: It’s a formidable task for a long time in China that how to utilize the land resources intensively and protect farmlands.The improvement of land use intensity is an important embodiment for the optimum land allocation.Market is the basic and efficient way to allocate resource. However, different market degrees can lead to different efficiencies of resource allocation and utilization.On the basis of building a framework of different land use efficiencies under the effect of market and government in different land market development stages, the article makes an empirical study on the development zones in Jiangsu province.By factor analysis and multifactors analysis model, and on the basis of the data of economy and land use in 2004, this study measured the development of land market and the intensity of land use in different land market stage.The result of the study suggests that on the whole, the stage of land market development is rather high, while the stage is different in different development zones.For example, the degree of land market in Wujiang and Nanjing development zones is 78% and 69% , respectively.The degree of land market in Yixing, Zhangjiagang and other 13 development zones is between 50% and 65%; at the same time, the degree of land market is between 30% and 50% in 23 development zones; and as for the remaining 4 development zones, the degree is only between 15% and 3 0%.So, the stage of land market in 33.4% of the development zones is in the end of transition to re latively mature stage; while the stage of land market in 57.1% of the development zones is in the m iddle transition stage.At the same time, the intensity of land use is different in different land marke t stages.The score of the intensity index of land use in the end of transition to relatively mature sta ge is 65.49, which is higher than that of the middle of transition stage.Because the score of intensit y index of the latter is only 48.85, the former is higher than the latter.So, the paper thinks the inno vation method to improve land use intensity is to change the mechanism of land management, and l et market mechanism become the main way to allocate land resource.
