- Abstract:
-
The low-carbon economy is an inevitable choice of urban sustainable development as well as a necessary way to adjust economic structure and to further change economic growth. A comprehensive evaluation of low-carbon economy that reflects the status of the city and level of low-carbon economy, reflects the low-carbon economy gap among different city. In this paper, taking Gansu Province as an example and using methods of principal component analysis,ArcGIS natural Breaks Classification, built the construction of the urban economy comprehensive evaluation index system of low-carbon. Thus, low-carbon economy level, spatial disparity and driving factors of twelve cities in Gansu Province were evaluated and analyzed. So that scientific foundation of decision-making to the development of Gansu Province low-carbon economy can be offered. The results showed that: the scores of Gansu Province low-carbon economy demonstrates right-skewed distribution, the range reaches 5.69, which indicates that the low-carbon economy level of Gansu Province is generally inadequate and low,low-carbon economy gap between difference cities was significant; the factors of driving low-carbon economy in different cities were in a multi-level of development pattern; there is a significant regional spatial differences in low-carbon economy, which was like ’two sides small, middle big’ of the olive structure. Therefore, the development of Gansu Province low-carbon economy should adequately take local conditions and consider different regions.
