Under the theoretical frame of urbanization effect on development of lowcarbon economy established according to the EKC Hypothesis and STIRPAT Model, a measurement of the efficiency of 20002011 development of lowcarbon economy in the 30 provinces and metropolitans of our country by the SBM Model and verification of the results by the Tobit Penaldata Model come to the following conclusions: Different provinces and metropolitans differ greatly in efficiency of development of lowcarbon economy, which tends to fall annually. The efficiency of lowcarbon economic development in Eastern China is higher than that in central and western China. Furthermore, the association between urbanization and development of lowcarbon economy throughout the country and in eastern and western China presents a reversedU curve while that in central China a U curve. The association between average DGP and efficiency of development of lowcarbon economy throughout the country and in central and eastern China presents a U curve whereas that in western China a reversedU curve. From the abovementioned, technological progress makes prominent positive effects on development of lowcarbon economy.
