To explore the method of creating a theoretical model of urban low-carbon economy evaluation, and analyze
the development status and level of low carbon economy in cities in the middle and lower reaches of Yangtze River;
Method To introduce the basic theory of low-carbon economy, the principle and the technical route for creating the
evaluation system of urban low-carbon economy, develop 3 layers of 5 categories of 18 evaluation indicators, conduct
weighted calculation using Delphi method, analytic hierarchy process(AHP) , fuzzy evaluation method and fuzzy AHP
method, investigate into 7 cities, such as Shanghai, Nanjing in the middle and lower reaches of Yangtze River, and evaluate
the urban low-carbon economic status using the created models; Results The evaluation result shows that at present
China has many cities at “medium to high carbon economy” or “high carbon economy” types. The development level of
low-carbon economy lagged behind many western countries; Conclusion It is a most efficient pathway to improve the present
low-carbon economic level by vigorously developing the low-carbon technology, developing the low-carbon environmental
education and promoting the low-carbon concept.
