Since the low鄄carbon economy ( LCE) was, firstly, brought out by the Department of Trade and Industry ( DTI) in UK in 2003, the issues related to the concept of low carbon ( LC) have attracted more and more attentions at home and abroad. The low鄄carbon development ( LCD) is one of the hottest issues in the academic circles. However, people remain to have some controversial viewpoints on this topic of LCD up to now. For example, some people think the LCD should guarantee the growth of Gross Domestic Product ( GDP) , but some others think the LCD could leave it out. Therefore, in this paper, the two concepts of LCE and LCD were, at the first step, distinguished based on some published literature.Then, according to the distinguished result above, the indicators忆 system for evaluating the LCD levels of different regions was constructed, which contains 5 second鄄layer忆s indicators and 10 third鄄layer忆s indicators. As the unavailability of data, some provinces were omitted, and there were 30 provinces altogether were taken into the numerical case. In the empirical research process, a two鄄step methodology of combining the Fuzzy Analytic Hierarchy Process ( FAHP) with the Technique for Order Performance by Similarity to Ideal Solution ( TOPSIS) method is proposed. The FAHP was, firstly, used to compute the indicators忆 weights of the 30 provinces忆 LCD levels, and then the TOPSIS method used these weights as its own input weights to complete the whole calculation process. The results show that: (1) the index system is a very practical and
