Research on Establishing City Low Carbon Economy Evaluation Theory Model

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.
