Based on the principles of scientific, systematic, practicality, hierarchy, the paper constructs the evaluation index system of the Possibility of Low-carbon Economic Development, and determines the assessment of evaluation indexes applying the analytic hierarchy process (AHP), and builds the multi-objective linear weighted evaluation function model. Taking the Province of Zhejiang for example, the Possibility of Low-carbon Economic Development was evaluated. The results can be summarized as follows: The construction the evaluation index system of the Possibility of Low-carbon Economic Development is scientific and has a certain operability; The development of low-carbon economy in Zhejiang Province is potential, and the comprehensive evaluation has 4 levels; From certain aspects, such as the establishment and improvement of the low-carbon economy policy system, management system for carbon emissions and carbon exchanges, the introduction of foreign advanced low-carbon technologies, the promotion of low-carbon consumption and low-carbon lifestyle, measures can be taken to promote the development of a low- carbon economy in Zhejiang Province.
