The Differences and Enhancing Potential of Provincial Carbon Productivity and Energy Efficiency
基于2011年中国省级数据，用DEA模型将各省分为四类区域，分析碳生产率和能源效率的差异及提升潜力，为区域差异化政策提供参考。
Based on the output-oriented CRS and VRS DEA's model, this paper analyzes Chinese provincial energy efficiency and carbon productivity in 2011. The calculation results show that all provinces were divided into four regions: high carbon productivity-high energy efficiency regions, low carbon productivity-high energy efficiency regions, low carbon productivity-low energy efficiency regions, high carbon productivity-low energy efficiency regions. Enhancing potential of carbon productivity in these regions is different. In order to enhancing carbon productivity, each province should be considering regional differences and then setting reasonable provincial target. The results can provide reference for different energy-economic policy of different regions.
