- 摘要:
- 发展低碳经济，是城市可持续发展的必然选择，也是推进经济结构调整，促进经济增长方式转变的必由之路。以甘肃省为例，构建了城市经济低碳度综合评价指标体系，运用因子分析法、自然断裂分类法，对甘肃省12个地级市的城市经济低碳度进行了实证分析，并对低碳经济空间差异、驱动因素分别讨论，以期为甘肃省发展低碳经济制定决策提供科学依据。结果表明：甘肃省城市经济低碳度综合得分曲线右偏，极差达到5.69，说明甘肃省低碳经济总体水平较低，各城市低碳经济水平高低不等；不同城市低碳经济驱动因素呈多层次、多水平的发展格局；低碳经济区域空间分异显著，呈“两头小，中间大”的橄榄形结构。
- 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.
