The whole life cycle management of industrial land is an important way to optimize the allocation of land resources and enhance the degree of intensive use. This report measures the entire life cycle of industrial land from two dimensions：enterprise life cycle and industrial land management cycle. The nonlinear regression model is used to identify the life cycle stage. The practical experience and practical contradictions in the whole process management of industrial land supply access stage，benefit evaluation stage and equity exit stage are analyzed. We explored the evaluation method of industrial land intensive use level based on life cycle. The results show that 66.1% of the enterprises in the study area have a life cycle of less than 5 years and 99.6% have a life cycle of less than 30 years；the level of intensive use of industrial land shows an upward and then downward trend with the evolution of the life cycle of enterprises，and the efficiency of industrial land use is low in the decline stage. There are prominent practical contradictions between the enterprise life cycle and the land supply period in the study area，such as the difficulty in the main body of post-supply supervision implementing，and the difficulty in promoting the revitalized exit mechanism. Therefore，flexible land supply and differentiated management policies should be implemented in accordance with the characteristics of the enterprise life cycle stage.
