我国区域经济发展的生态效率差异研究——基于2007年省际数据的实证分析

经济、资源和环境协调发展是当前研究的重要课题。基于生态效率理论，采用因子分析法，以2007年省际数据为样本，测算了各省域经济发展的生态效率值。结果显示：节能减排与水资源利用水平对生态效率的影响较大，我国区域经济发展的生态效率值差异明显，沿着东、中、西部三大经济带空间依次递减，中西部地区的各省域及整体生态效率值均低于全国平均水平。根据以上研究结论提出改善建议，旨在为我国指导经济发展与资源、环境协调可持续发展提供宏观参考。

Research on the Regional Eco -efficiency Based on Factor Analysis --Evidence from Provincial Data 2007

The coordinated development of economy, resources and environment is an important subject of current research. By the theory of eco - efficiency, with factor analysis method, estimated the value of provincial eco - efficiency for inter - provincial data 2007. The result showed that energy - saving ＆emission - reduction and water - using lever have a great compact on eco - efficiency. The eco - efficiency disparity of regional economic development is significant, declining from east to west, the eco - efficiency values of the overall and their provincial regions of the central area and western area are lower than the national average. Based on the above finding , it made improvement recommendations to provide overall guidance and reference for advancing Chinese sustainable development in harmony with nature.
