Abstract: Facing the national condition that there are a large number of populations but small land area，and staying in the accelerated urbanization and industry development stage，it is an important composite how to allocate the land resource reasonable and efficient use in the development research. The evaluation on the benefits of urban construction land input provides a theoretical and scientific significance to the rational allocation of land resources，so it is very important to do the evaluation study. Based on understanding the benefits of urban construction land input，this article considers that the benefits of urban construction land input is an objective reflection on the productive elements input-output efficiency，the coordination among the artificial composite ecological system internal’s economic benefit，social benefit and ecological environment benefit，the load bearing capacity，the reasonable degree of the regional relationship and the institutional arrangement，and then according to this，the article built the evaluation system，took the thirty provinces as research subject，and used SPSS Statistical software，combining with “China Statistical Yearbook 2010” relevant data to do the research. The result shows that: （1） the benefits of our country urban construction land input shows two typical characteristics: level feature——the growth is extensive and efficient，and the couple degree of internal economic，social and ecological environment is low; vertical feature——differentiation significant，and the whole level shows a following trend: In China the east region’s score>western region’s one>northeast region’s one >middle region’s one; （2） the pattern shows that economic benefit （3.5005）> social benefit （3.0193）>environment benefit （1.3329），to some degree，it reflects the fact that national macro development strategy relatively attaches more importance to social fairness than to efficiency，which distorts the inter-regional relations value seriously （person-person contradiction）. In a word，the benefits evaluation system takes into account the equity and efficiency，man and nature，and also provides a basis protection for the urban construction configuration，and a method to solve regional ecological compensation，and financial transfer payment of the provinces and provincial areas of social，economic，ecological and environmental sustainable development. It is a reasonable and operable urban construction land input benefits evaluation system. It can be used to dynamically supervise the reasonability of national urban construction land input，and to adjust the allocation of the land input of the nation.
