The land conversion is a major source of CO2 in urbanization. The expansion of the extension of the city lending to agricultural land and its cover has been continuously reduced, which not only lead the green vegetation in fixed carbon to release, but also because of the lack of vegetation to absorb carbon caused a significant increase greenhouse gases in atmosphere. To reduce the CO2 in the atmosphere, this paper studies carbon emissions and coordinating between carbon emissions reduction and economic development from an efficiency point. Based on DEA environmental technology, this paper estimates eco-efficiency of carbon emissions caused by single element of nonagricultural land in the process of urbanization and industrialization, and further analyzes carbon emissions reduction and economic development coordinated degrees. Comparative of similar studies have found that carbon emissions are mainly caused by land use change, other input elements contribution to carbon emissions are in a secondary position in urbanization and industrialization process; It is mainly through the intensive use of land to achieve coordination between carbon emissions and economic development Therefore, it is crucial to use land resources rationally to achieve carbon reduction in urbanization and industrialization.
